4. A Biblioteca do Mixx

4.1. Visão geral dos recursos da Bilbioteca

A Biblioteca do Mixx

The library manages all of your music files. This is where you can find the tracks you want to play and load them into a deck or sampler; see Carregando Faixas. Mixxx imports your music library automatically when it is run for the first time, see Changing music directories for more information.

If you want to backup (or delete) your library refer to The Mixxx Settings Directory and look for mixxxdb.sqlite.

A barra lateral na esquerda contêm diferentes coleções de música. A visualização da lista de faixas na direita mostra as faixas nessas coleções.

Barra Lateral:

• Pesquise: Procur por faixas na sua biblioteca do Mixxx.

• Tracks: View and edit your whole collection.

• Auto DJ: Automaticamente carrega e faz transição de faixas para mixagem sem acompanhamento.

• Playlists: Arrange tracks in a set order.

• Crates: Organize tracks in (unordered) collections.

• Computer: Navigate, view, and load tracks from folders on your hard disk and connected devices.

• Gravações: Grave sua mixagem e veja suas gravações anteriores.

• History: Browse lists of tracks played in past mixing sessions.

• Analyze: Generate Mixxx-specific data for tracks before a gig.

• Bibliotecas Externas: Acesse suas bibliotecas existentes do iTunes, Traktor, Rhythmbox e Banshee.

Lista de Faixas:

• Ordene: Mostre e ordene as coleções de faixas por diferentes critérios.

• Carregue: Arraste as faixas que você quer tocar para o mostrador de onda.

• Edite: Avalie as faixas e edite as propriedades das faixas.

4.2. Tracks - View and edit your whole collection

A sortable list of all the tracks in your music library.

Personalizando a visualização

Move columns by clicking a column header and dragging it to another position. Right-click on a column header to show or hide individual columns. Adjust the column width to fit the contents of the rows by double-clicking on the separator between two column headers.

Ordenando Faixas

As faixas são ordenadas automaticamente pela coluna ativa. Clique em um topo de coluna ativo para inverter a ordenagem. Clique em outro topo de coluna para mudar a coluna ativa.

• Multi-Column sorting

  You can sort multiple columns by clicking up to three column headers you wish to sort your tracks by. This makes searching for tracks in a large list more efficient. Clicking twice on a column header will reverse the sort order.

  Example:

  1. Click on the BPM column header -> list is sorted by BPM

  2. Click on the Year column header -> list is sorted by year. If year is equal, it is still sorted by the last criteria, e.g. BPM.

  3. Click on the Genre column header -> list is sorted by genre. If genre is equal, it is still sorted by year. If genre and year is equal, then it is sorted by BPM.

• Random sorting

  Click on the Preview column header to randomly sort tracks.

• Sort keys by circle of fifths

  Click on the Key column header. The order starts with C at the top, then its relative minor (a), then adds 1 sharp (G), then G’s relative minor (e), and so adding sharps/removing flats around the circle of fifths. For Lancelot notation, it starts with G#m at the top, which is 1A in that notation, and proceeds alphanumerically (minor keys appear before their relative major keys in this case).

Avaliando faixas

Esteje certo de que a coluna Avaliação não está escondida. Avalie faixas ao clicar nas estrelas do campo de avaliação.

Edição de Faixas na Linha

Mixxx reads metadata from the tracks to fill the columns of the library. Double-click on a field, edit the data, and hit Enter when you are done. Go to the chapter edit metadata for detailed information.

Carregando faixas

To load a track into a deck, you can either drag it to the waveform display, use the context menu or use keyboard shortcuts. Go to the chapter Carregando Faixas for detailed information.

Importando faixas

Mixxx imports your music library automatically when it is run for the first time. Go to the chapter Changing music directories for detailed information.

Pré-escutando faixas

To pre-listen to tracks in your headphones without loading them to a regular deck, click the icon in the Preview column. Go to the chapter Pré-escutando Faixas for detailed information.

Arte da Capa/Álbum

Mixxx can display cover art it finds for a track in the library. It will search for available cover art in the following places in order and will use the first one it finds:

1. The first image saved in the track’s ID3v2/Vorbis tags

2. An image file in the track folder (if there is only one image file there.)

3. %arquivo-base-da-faixa%.jpg no diretório da faixa para %arquivo-base-da-faixa%.mp3

4. %álbum%.jpg

5. cover.jpg

6. front.jpg

7. album.jpg

8. folder.jpg

O MIxxx suporta os seguintes tipos de imagem: jpg, jpeg, png, gif, bpm

Reexaminar a Biblioteca

If you want to manually refresh your library without exiting (for example because you added or moved files) you can do this with Library ‣ Rescan Library in the menu at the top of the application window. You can prompt an automatic rescan when Mixxx is started under Preferences ‣ Library ‣ Rescan on startup.

Rescanning the library will add new files to the library and mark tracks as missing if the corresponding file has been deleted. It tries to detect and relocate missing tracks if files have been renamed or moved into another directory.

Automatically refreshing the metadata of tracks when files have been modified by an external application is not supported, yet. In this case you need to select the affected tracks and (re-)import their metadata from file tags.

Menu de contexto da lista de faixas

Clicando com o lado direito nas faixas selecionadas na lista de faixas revela o menu de contexto:

• Add to Auto DJ

  Adds the content of the selection to either the bottom or top of the Auto DJ playlist for automatic mixing. The replace option deletes the Auto DJ queue first, and then fills it with the selected tracks.

• Load to

  Loads a selected file to one of the available Decks, Samplers or to the Preview Deck. Alternatively simply drag it to the Mostradores de Onda. The number of available decks and samplers might differ, depending on the selected skin. Note that you can’t load multiple files at once.

• Add to Playlist

  Add selected tracks to an existing playlist, or drag the selection to a playlist crate in the sidebar. Choose Create new playlist to put them into a new playlist.

• Crates

  The checkbox shows in which existing crates the selection is in. Changing the crates selection does not collapse the menu, which allows much easier categorization of tracks without going through the menu from scratch. Choose Create new Crate to put them into a new crate.

• Select Color

  Assign a color to all selected tracks to indicate mood, energy etc. Select the black button at the top left to remove the color.

• Metadata

  • Import from File Tags: If the track’s metadata changes, (e.g. if you used iTunes to edit it,) this option lets you save the new values for the selected tracks to the Mixxx library. See edit metadata.

  • Import from MusicBrainz: Look up metadata online by searching the MusicBrainz database and apply the search results to your tracks. See edit metadata.

  • Export to File Tags: Saves metadata to files. Mixxx may wait to modify files until they are not loaded to any decks or samplers. If you do not see changed metadata in other programs immediately, eject the track from all decks and samplers or shutdown Mixxx.

  • Cover Art

    • Choose New Cover: Select an image from the file browser as the cover.

    • Clear Cover: Delete any cover information saved for this track.

    • Reload from track/folder: Reload the cover from the tracks” ID3v2 tags or a picture in the track folder if the tags do not supply any.

• Clear

  • BPM and Beatgrid: Removes the BPM and beatgrid data from the selected tracks in the Mixxx library. After doing this, we recommend analyzing the tracks again.

  • Play Count: Marks selected tracks as not played in the current session and sets their play counter to zero. The icon in the Played column changes.

  • Hotcues: Clears all saved hotcues and hotcue labels.

  • ReplayGain: Clears all saved ReplayGain values.

  • Waveform: Clears the saved waveform data from the selected tracks. This is useful if a file is overwritten by another file of the same name, or was edited externally (e.g. in a waveform editor). To clear the waveform cache for all tracks in the library, select Preferences ‣ Waveforms ‣ Clear cached Waveforms .

  • All: Clears all of the data above from the Mixxx library database at once.

• Change BPM

  • Allows to change the BPM to 50%, 66%, 75%, 133,33%, 150%, or 200% of the BPM set by Mixxx when analyzing the tracks. If many of the detected BPM values are incorrect, you may try other settings in the Analyzer Settings and re-run the analysis.

  • Travar/Destravar o BPM: Trava/Destrava o BPM das faixas selecionadas para que você não possa editar eles nas propriedades da faixa. O ícone perto do BPM da faixa na coluna da biblioteca é alternável. Clicar ele vai definir o seu estado para «travado», e o ícone muda para .

• Hide from Library

  Temporarily hides selected tracks from the track list. Hidden tracks are listed in the Hidden Tracks menu item which is explained below.

• Open in File Browser

  Brings up the selected files in your file manager.

• Properties

  Similar to inline editing explained above, the properties dialog allows you to view and edit metadata such as title, artist, album, and view the full file name and path. Note that you can not edit multiple files at once.

Nota

A maioria dos itens do menu de contexto também estão disponíveis nas listas de arquivo das outras visualizações como no Auto DJ, nas Listas de Reproduções, e nas Caixas.

Músicas Faltando

The Missing Tracks view is accessible by expanding the Library tree item in the sidebar. Any tracks that were previously loaded into your library but were later not found on your drive will appear here. Mixxx does not automatically delete records of missing tracks so that extra metadata Mixxx might have (such as hot cues and beat grids) will not be lost in case the file is replaced.

As funcionalidades em detalhe:

• Botão de Selecionar Tudo: Seleciona todas as faixas na visualização atual.

• Botão Eliminar: Elimina as faixas selecionadas da biblioteca do Mixxx, mas não remove elas do seu computador. Isso vai deletar todos os metadados que o Mixxx tem da faixa.

Músicas Escondidas

The Hidden Tracks view is accessible by expanding the Library tree item in the sidebar. Any tracks that were previously loaded into your library but were later set to be hidden from the library will appear here. Use the Hide from Library context menu item in the tracks view to temporarily hide selected tracks.

As funcionalidades em detalhe:

• Botão de Selecionar Tudo: Seleciona todas as faixas na visualização atual.

• Botão Eliminar: Elimina as faixas selecionadas da biblioteca do Mixxx, mas não remove elas do seu computador. Isso vai deletar todos os metadados que o Mixxx tem da faixa.

• Unhide Button: Removes the selected tracks from the Hidden Tracks view and makes them available in the regular track lists again. The tracks will re-appear in every playlist or crate they were in before being hidden.

Veja também

To learn how to permanently remove tracks from the Mixxx library using the Hidden Tracks view, see permanently remove tracks.

4.3. Carregando Faixas

Faixas podem ser carregadas em um deck de várias maneiras:

• Right-click the library track table: Right-clicking on a track in the table will present the options Load in Deck 1 and Load in Deck 2, among others. Making either selection will load a track into a deck.

• By Usando um Teclado to load the selected track in the library track table. Use keyboard ↑ and ↓ arrow button to select a track, Shift + ← to load into Deck 1 and Shift + → to load into Deck 2.

• Drag-and-drop from library track table: Dragging-and-dropping a track from the track table onto a waveform display will load the track into that deck.

• Drag-and-drop from deck to deck: Once you’ve loaded a track to deck, sampler, or preview deck, click on the track title, track artist or cover art and drag it to another deck or sampler. Note that you can also drop tracks onto Playlists and Crates in the sidebar, as well as into track tables of active Playlists or Crates.

• Drag-and-drop from external file browser: Dragging-and-dropping a track from an external file browser directly onto a waveform display in Mixxx will load that track. This function also works with some other applications. For example, on macOS, dragging-and-dropping a track from iTunes onto one of Mixxx’s waveform displays will load it into that deck.

4.4. Procurando Faixas (Pesquisa)

The search function filters the currently displayed list (e.g. a playlist, a crate, or even the whole library) for tracks that match your search query.

• Activate the search input field by clicking in it or pressing CTRL + F (Windows/Linux) or CMD + F (Mac).

• Type your search term(s). Mixxx filters the tracks as you type and shows only those matching the search term(s). Search terms can include an artist’s name, a song title, BPM, etc.

• Para limpar o campo de pesquisa pressione ESC ou clique no botão limpar perto do campo.

• Hit TAB to cycle between the search and the list of results in the library. Use the ↑ and ↓ keys to scroll in the list of results.

Nota

Se o campo de pesquisa estiver com foco, os atalhos de teclado estarão desativados, veja Usando um Teclado.

Usando operadores de pesquisa

Operadores de pesquisa permitem que você forme pesquisas mais complexas. Elas permitem que você limite certos termos de pesquisa para propriedades particulares de suas faixas.

O Mixxx suporta os seguintes filtros:

• Text filtering: album_artist, album, artist, comment, composer, crate, genre, grouping, location, title

  Examples

  artist: “com truise”
  album:Danger
  genre: Trance
  title: foo
  composer: foo
  comment: foo
  genre:hip-hop -genre:gangsta
  

  Nota

  It doesn’t matter if you have space between the colon and the argument or not. Quotes must be used for multi-word text arguments.

• Numeric filtering: bitrate, bpm, played, rating, track, year

  Examples

  bpm:140
  bpm: >140
  year: <2010
  bpm: >=140
  rating: <=4
  bpm: 140-150
  played: >10
  

  Nota

  You can put a space after the colon but currently there must be no space between the operator and the number.

• Special filtering: key, duration, added, dateadded, datetime_added, date_added

  • Supports fuzzy matching of key searches. The following example lists tracks with harmonically compatible keys to C# minor.

    ~key:c#m
    

    You can combine operators but there’s no way to do an “OR” search right now. The following example lists all tracks by “Danger” over 3 minutes long that are rated 4 or 5.

    artist:Danger duration:>3m rating:>=4
    

  • Filtros de pesquisa negativos. Use o prefixo - como operador de negação. O exemplo seguinte vai encontrar “hip-hop“ de qualquer ano menos o de 1990.

    genre:hip-hop -year:1990
    

  • Search for empty fields. The following example lists all tracks without a genre. It works for all text fields, including crates.

    genre:""
    

  Examples

  duration:2m10
  duration:<2:10
  duration:>1m35s
  duration:>62
  

  Nota

  You can put a space after the colon but currently there must be no space between the operator and the number.

4.5. Pré-escutando Faixas

To pre-listen to a track, activate the Preview column in a library view. Clicking the icon in the library’s Preview column loads the selected track into a special Preview Deck that will only output sound in the headphones channel. Click the icon to stop the playback.

Alternativamente, selecione uma faixa da lista de faixas da biblioteca do Mixxx, arraste a faixa para a visualização de ondas do Deck de Pré-escuta e clique no botão Tocar perto das ondas.

To display the Preview Deck, press CTRL + 4 (Windows/Linux) or CMD + 4 (Mac).

Dica

Click on the Preview column header to randomly sort tracks.

4.6. Edite os metadados dos arquivos de áudio

O MIxxx lê metadados relevantes das faixas e mostra eles nas colunas da biblioteca. Você é livre para editar a maioria dos metadados, e o Mixxx oferece um número de diferentes formas de fazer isso. Note que algumas informações não podem ser editadas, como a taxa de bits, tamanho, duração, tipo, nome do arquivo e localização.

Nota

O Mixxx não suporta a edição de metadados de várias faixas ao mesmo tempo (edição em massa).

Aviso

Mixxx won’t touch your audio files by default. Changes to a track’s metadata will be saved to the Mixxx library, but not to the track itself.

If you wish to write modified track metadata from the library into file tags, check the box in Preferences ‣ Library ‣ Track Metadata Synchronisation.

Edição Manual

Edição de Faixas na Linha

To enable inline editing in the library go to Preferences ‣ Library ‣ Miscellaneous and check the box «Edit metadata after clicking selected track».

Select any track in the library and click on the field you want to edit. If the field is editable, it will become an editable text box. Enter a value and hit Enter when you are done.

Biblioteca do Mixxx - Edição na linha

Editor de Propriedades:

To open the editor right-click on a single track in the library or any track label in decks or samplers, then select Properties in the track menu. You can also double-click any track label in the decks or samplers to open the editor directly.

Add or change values in the editable fields, and save your changes as explained below.

Biblioteca do Mixxx - Editor de Propriedades

• OK: Aceita as mudanças e fecha o editor.

• Apply: Accept the changes and leave the editor open.

• Cancelar: Descarta as mudanças e fecha o editor.

• Anterior/Próximo: Carrega a faixa seguinte ou anterior na visualização atual da biblioteca.

• Import Metadata from File: Prompts Mixxx to re-read the metadata of the selected track (such as when you have modified it externally with another application.)

• Import Metadata from MusicBrainz: Look up metadata on-line by searching the MusicBrainz database. See below.

Usando a base dados online do MusicBrainz

MusicBrainz is an open-source music encyclopedia that collects music metadata and makes it available to the public.

Biblioteca do Mixxx - Assistente MusicBrainz

The MusicBrainz wizard in Mixxx allows searching the MusicBrainz database and applying the results to your tracks.

Clique em uma única faixa da biblioteca e selecione Obter Metadados no MusicBrainz. O Mixxx busca dados da faixa do banco de dados do MusicBrainz e mostra os resultados da busca.

Select the best match from the search results by clicking on it in the list.

• Aplicar: Aplica os metadados selecionados no MusicBrainz na faixa.

• Fechar: Fecha o assistente.

• Previous/Next: Load the previous or next track in the current library view and perform a MusicBrainz lookup on it as well.

Fetching track metadata from MusicBrainz can fail:

• if Mixxx is unable to find the specified track in the MusicBrainz database,

• if Mixxx cannot reach the MusicBrainz servers (if they are down),

• or if you are not connected to the Internet.

Dica

The MusicBrainz service has been designed for identifying full audio files. If a track is less than 2 minutes long, identifying the file will likely fail. Identifying a layered mix-track or mash-up may produce false positives in the result list.

Using third-party software

If you have edited file metadata in third-party software you need to re-import the modified metadata into Mixxx manually by selecting the affected tracks, open the context menu, and then choose Metadata ‣ Import From File Tags.

Dica

Rescanning the library with Library ‣ Rescan Library in the menu on top of the application window will only detect newly added or removed tracks but no modifications of existing tracks. This is a known limitation.

Softwares populares para editar metadados dos arquivos de áudio incluem:

• Mp3tag (Windows)

• Kid3 (Mac, Windows, Linux)

• Picard (Mac, Windows, Linux)

4.7. Auto DJ - Automatize a sua mixagem

The Auto DJ queue is a special playlist that contains extra controls for automatic mixing. This is useful when taking a break from live mixing or for using Mixxx as media player.

As funcionalidades do Auto DJ em detalhe:

• Shuffle button: Randomizes the order of tracks in the Auto DJ playlist.

• Add Random button: Adds a random track from track sources (crates) to the Auto DJ queue. If no track sources are configured, the track is added from the library instead.

• Botão Pular faixa: Pula a próxima faixa da lista de reprodução do Auto DJ.

• Botão Desvanecer agora: Começa a transição para a próxima faiax.

• Transition time spin-box: Determines the duration of the transition. A negative value will add a pause between tracks.

• Selection Info label: Displays the duration and number of selected tracks. Press Ctrl + A to get the total duration of the AutoDJ queue.

• Botão Ativar Auto DJ: Liga/Desliga o modo Auto DJ.

The Skip track, Add Random and Fade now buttons are only accessible if the Auto DJ mode is enabled. The Search field in the upper left corner is disabled in Auto DJ. By default, Auto DJ removes tracks after playing them but if you want it to play the same tracks over and over again, you can activate the Auto DJ Requeue option in Preferences ‣ Auto DJ ‣ Re-queue tracks after playback.

Auto DJ Crates

It is possible to add random tracks to the bottom of the Auto DJ playlist. The tracks are chosen from a set of crates that you have set as a source for Auto DJ, or from the standard library. Mixxx will normally try to select tracks that haven’t yet been played. You can set a minimum number of tracks that are always available for selection no matter when they were last played in Preferences ‣ Auto DJ ‣ Minimum available tracks in Track Source.

Para mais informação, vá para o capítulo Auto DJ.

4.8. Playlists - Arranging tracks in a set order

Playlists are ordered lists of tracks that allow you to plan your DJ sets. Some DJs construct playlists before they perform live; others prefer to build them on-the-fly.

Playlists are not directly loadable into decks as Mixxx is primarily intended for live, attended performance use. However, you can right-click a playlist to queue it to Auto DJ, so in a sense you can «play» it.

• Create a playlist: Right-click on the Playlists sidebar item and select Create New Playlist. Name the playlist and click OK. The total number of tracks and total duration are displayed next to the name.

• Import playlists: Right-click on the Playlists sidebar item and select Import Playlist. Select one or more playlists and click OK. Mixxx creates an import of these existing external playlists as new Mixxx playlists.

• Add Tracks: Add tracks to a previously created playlist by dragging-and-dropping a selection of tracks from the library or playlists onto the name of a playlist in the sidebar. Alternatively, use the right-click context menu in the library’s track list.

  Dica

  If you have a track selected in the library, all of the visible playlist and crates that it is in are shown in bold.

Right-click on an existing playlist name to access the different features in the context menu:

• Adicionar ao Auto DJ: Adiciona o conteúdo da lista de reprodução à fila do Auto DJ para mixagem automática.

• Rename: To rename a playlist, just enter a new playlist name and click OK.

• Duplicar: Algumas vezes você quer construir uma lista de reprodução baseado em uma existente. Selecione a lista de reprodução que você quer duplicar, escolha Duplicar Lista de Reprodução, nomeie a nova lista de reprodução e clique OK.

• Remove: Removes an unlocked playlist. Tracks that were in the playlist remain in the library for later use.

• Travar: Esse ícone indica uma lista de reprodução travada. Se uma lista de reprodução é travada, você não pode adicionar faixas, renomear ou deletar a lista de reprodução. Escolha Destravar no menu de contexto para destravar a lista de reprodução.

• Analyze entire playlist: Forces the analysis of the tracks in the playlist in the Analyze view.

• Import playlist: Import tracks from external playlists in various file formats to the selected playlist. For more information, go to Using libraries from other software.

• Export playlist: Export a playlist to various file formats such as m3u, m3u8, pls, txt, or csv. This allows you to use the data in other applications.

• Export Track files: This copies all of the tracks in a playlist into a folder such as an external USB stick. Only files are copied, not Mixxx-specific metadata like waveforms or cover art that is not embedded in the file.

4.9. Crates - Organizing tracks into collections

Crates are unordered collections of tracks, just like DJ cases holding your favorite records.

• Create a crate: Right-click on the Crates sidebar item and select Create New Crate. Name the crate and click OK. The total number of tracks and total duration are displayed next to the name.

• Import crates: Right-click on the Crates sidebar item and select Import Crate. Select one or more playlists and click OK. Mixxx creates an import of these existing external playlists as new Mixxx crates.

• Add Tracks: Add tracks to a previously created crate by dragging-and-dropping a selection of tracks from the library or playlists onto the name of a crate in the sidebar. Alternatively use the context menu in the library’s track list.

Clique com o lado direito em um nome de caixa existente para acessar diferentes funcionalidades no menu de contexto:

• Renomear: Para renomear uma caixa, digite o novo nome da caixa e clique OK.

• Duplicar: Como nas listas de reprodução, você pode duplicar uma caixa existente. Selecione a caixa que você quer duplicar, escolha Duplicar Caixa, nomeie a nova caixa e clique OK.

• Remover: Remove uma caixa destravada. As faixas na caixa ainda vão estar disponíveis na biblioteca para uso futuro.

• Travar: Esse ícone indica uma caixa travada. Se uma caixa é travada, você não pode adicionar faixas, renomear ou deletar a lista de reprodução. Escolha Destravar no menu de contexto para destravar a caixa.

• Auto DJ Track Source: Use this crate as a source for random tracks in Auto DJ, see Auto DJ crates .

• Analisar Toda a Caixa: Força uma análise da caixa na visualização Analisar.

• Import crate: Import tracks from external playlists in various file formats to the selected crate.

• Export crate: Export a crate to various file formats, such as m3u, m3u8, pls, txt, or csv. This allows you to use the data in other applications.

• Export Track files: This copies all of the tracks in a crate into a folder such as an external USB stick. Only files are copied, not Mixxx-specific metadata like waveforms or cover art that is not embedded in the file.

Caixas vs. Listas de Reprodução

Crates are unordered collections of tracks. Unlike playlists, they cannot contain duplicate entries and do not support arranging tracks within them.

Often DJs group tracks by genre, keep lists of favorite tracks, and/or prepare lists of tracks they want to play at a particular party. In these cases they rarely care about the order since they will choose it at the party based on the dance floor and mood. They certainly don’t want duplicates in these lists. Crates serve these purposes. You can think of them like labels in GMail or Web 2.0 tags for your music.

If however you want to plan out a specific set and practice the transitions, you will want an ordered list of tracks. Playlists serve this purpose.

4.10. Computer - Loading tracks from anywhere on your computer

This mode works like a file manager and allows you to load tracks from anywhere on your computer and connected devices, that are not necessarily already in your Mixxx library.

Click the Computer sidebar item to navigate the computer and find your music. Depending on your operating system, your music will usually be found in the “My Music” or “Music” folder. Drag the files you want to import to the Tracks icon or directly to the Mostradores de Onda.

Nota

Currently you can only drag files (not folders) to the Mixxx library.

Right-click on a folder and choose Add to Library to add the folder as an additional music directory. Mixxx will watch this directory and its subdirectories for new tracks.

Veja também

For more information, go to Changing music directories.

Atalhos - Marque suas pastas favoritas

Usando o sub-menu Atalhos você pode marcar suas pastas para acesso direto. Clique no item da barra lateral Navegador e navegue até a pasta que você quer marcar. Clique com o lado direito e escolha Adicionar aos Atalhos. A pasta então vai estar em baixo dos Atalhos. Para tirar a pasta de lá, clique como o lado direito e escolha Remover dos Atalhos.

4.11. Gravações

In this section of the library you can start and stop recording your session as well as view previous recordings and the dates they were made.

Veja também

Para mais informação, vá para Gravando sua Mixagem.

4.12. History - Keep track of your sessions

The history section automatically keeps a list of tracks you play in your DJ sets. This is handy for remembering what worked in your DJ sets, posting set-lists, or reporting your plays to licensing organizations. Every time you start Mixxx, a new history section is created. If you don’t play any tracks during the session, it will be discarded.

Esse ícone indica a sessão atual.

Click on the History icon in the sidebar to switch to the History view, then right-click on a session’s name/date to access the different features:

• Adicionar ao Auto DJ: Adiciona o conteúdo da sessão à fila do Auto DJ para mixagem automática.

• Rename: Rename a session. The default is the calendar date (YYYY-MM-DD).

• Remove: Remove a previous (unlocked) session. (You cannot remove the current session.)

• Lock: Protect a previous session against accidental merge or deletion. An icon indicates a locked session.

• Create new history playlist: Split off the current history session and add a new session without having to restart Mixxx. The current history must contain at least one track for this option to be available.

• Join with previous: Append the selected history session to the end of the previous one.

• Export playlist: Export a session in various file formats. This allows you to use the data in other applications.

4.13. Analisar - Prepare suas faixas

This section allows you to analyze your tracks in advance of loading them into a deck. Analyzing tracks requires considerable CPU power and may cause skips in the audio while performing, so it helps to have your tracks analyzed before you play. See Analise sua biblioteca for details.

4.14. Using libraries from other software

Bibliotecas suportadas:

• iTunes (Windows, macOS)

• Traktor (Windows, macOS)

• Rhythmbox (GNU/Linux)

• Banshee (Windows, macOS, GNU/Linux)

• Serato (Windows, macOS)

• Rekordbox (Windows, macOS)

The external library views allow you to use music libraries you have created in these third-party applications. You can access music as well as playlists. If available, Mixxx automatically loads the external libraries from their default locations on your hard drive.

Nota

Ao tocar uma faixa de uma biblioteca externa, ela vai ser adicionada à sua biblioteca do Mixxx.

Veja também

External libraries can be disabled under Preferences ‣ Library.

Using the iTunes/Traktor/Rhythmbox/Bashee/Rekordbox library

Clique com o lado direito no ícone do iTunes na árvore da Biblioteca e selecione Escolher Biblioteca para carregar o iTunes Music Library.xml de um lugar diferente. Selecione Usar Biblioteca Padrão para resetar.

• Right-click on a iTunes/Traktor/Rhythmbox/Banshee playlist and choose Import Playlist to import it into a new Mixxx playlist.

• If you have an iTunes configuration file (*.xml) from a Windows or Mac partition mounted in Linux, you can load it and use your iTunes tracks and playlists as well.

Using the Rekordbox library

To read Rekordbox databases for CDJ/XDJ players on USB or SD devices, the database has to be exported to a USB or SD device with a FAT or HFS file system using the Rekordbox Export mode. Databases that have been moved to an external device via Preferences > Advanced > Database management in Rekordbox are not supported.

1. Plug your USB or SD drive in while Mixxx is running.

2. Click on the Rekordbox item in the library sidebar to scan for Rekordbox prepared USB drives. If no Rekordbox devices show up, you can click on Check for attached Rekordbox devices (refresh).

3. Click on the desired removable device. All your folders and playlists will be revealed for you to play from.

How Rekordbox hotcues, memory cues, and loops are imported

The following data is read:

• Folders

• Playlists

• Beatgrids

• Hot cues

• Memory cues

• Loops

Mixxx currently has one main cue point, one loop, and thirty eight hotcues. As such:

• All Rekordbox hotcues are mapped to Mixxx hotcues as expected, the first chronological Rekordbox memory cue is mapped to the Mixxx main cue.

• The first chronological Rekordbox loop is also mapped to the Mixxx loop.

• All loops (including the first loop), and all subsequent Rekordbox memory cues are appended as Mixxx hotcues following the previously imported Rekordbox hotcues.

• The hotcue and memory cue colors you assigned in Rekordbox are also imported, assisting in distinguishing between them.

Although additional imported Rekordbox loops only appear in Mixxx 2.3 as hotcues, their loop information is stored in the Mixxx library and will become usable in Mixxx 2.4.

Using the Serato library

Mixxx supports reading your Serato library and crates both from your local hard drive as well as portable USB drives. Smart crates are currently not supported.

Serato stores information such as hot cues, track color and beatgrid in the file tags. Regardless of whether a track is loaded into deck from the library or directly from the file browser, Mixxx will import that information automatically if present.

Saved loops are imported as well, but since Mixxx is lacking support for multiple saved loops, only the first loop is usable in Mixxx. All other saved loops can be used like regular hotcues for now.

Waveforms, Gain values and «Flips» are not imported from Serato.

Nota

Due to differences in the metadata format, importing Serato information from Ogg Vorbis files is currently not supported.

To import Serato libraries from external USB drives:

1. Copy music library from Serato into external USB drive

2. Plug in USB drive while Mixxx is running

3. Click on Serato in the library. All USB drives containing a Serato library will be detected automatically.

4. For each removable device, the library and all crates from Serato will accessible.

If you have already added a track containing Serato Metadata to your Mixxx library in a Mixxx version that didn’t support reading that data, you can reimport it from the file’s tags via the track context menu.

Aviso

This action will clear your existing cuepoints in Mixxx if the file contains Serato Metadata

To reimport metadata from files:

• Right click on the track to show the context menu

• Select Metadata ‣ Import From File Tags.

Dica

Decoders may slightly detect different track start and end times for files from different sources, this could possibly be because of the presence of countless encoders and decoders for MP3 and M4A/AAC. This problem may cause your cues to be shifted up by a few milliseconds. Mixxx might not always be able to mitigate this problem, but it’s possible to shift all cues for a track at once as a workaround.

4.15. Removing tracks from the library

Removing tracks from the Mixxx library will not physically delete them from your drive. However it does delete extra metadata Mixxx might have (such as hotcues and the beatgrids), and removes links to playlists or crates.

1. Click the Library item in the sidebar.

2. Find and select the tracks you want to remove, perform a right-click on them and select Hide from Library from the context menu.

3. Expand the Library item in the sidebar and click on the Hidden tracks sub-item. All tracks that were set to be hidden from the library will appear here.

4. Select the tracks you want to remove, or use the Select All button.

5. To confirm you want to permanently remove these tracks from the library, click Purge.

Dica

If you want to hide or purge only tracks from a specific folder you may use the location: search operator, or sort the table by «Location».

Dica

If you later decide to add some of the deleted tracks back, import them to the Mixxx library again, see Changing music directories.

4.16. Compatible file formats

Mixxx supports a variety of audio file formats:

Sem Perdas	Com perdas
FLAC (flac)	MP3 (mp3)
Wave (wav)	Ogg Vorbis (ogg)
Aiff (aiff, aif)	AAC (aac, m4a, mp4)
	Opus (opus)

Lossless formats preserve every detail of the original recording and are recommended for the best sound quality. The FLAC format compresses the files to take less space on your computer without sacrificing audio quality. WAV and AIFF files are uncompressed and take up much more space.

Lossy formats take up less storage space on your computer than lossless formats at the expense of reducing sound quality. Assuming an average track length of about 4 minutes, a 1 TB hard drive or solid state drive can store about 42000 FLAC files or about 115000 MP3 files at 320 kbps.

There is no benefit to converting lossy file to lossless formats. The detail lost when making the lossy file cannot be recovered.

AAC (M4A) is supported on Windows Vista and macOS 10.8 onwards. The Platform Update Supplement is required for Windows Vista.

On Linux, AAC playback is disabled by default due to licensing restrictions. To enable the playback of AAC files, build Mixxx from source with m4a/AAC files support.

Aviso

DRM protected files, such as m4p files purchased in the iTunes Store in 2009 or earlier, are not supported.

Aviso

ALAC files use the same container MP4 container format and file extensions (m4a, mp4) as AAC files, but Mixxx cannot play ALAC files. It is recommended to convert ALAC files to FLAC for use in Mixxx. This will not reduce the sound quality of the files.

4.17. Music from audio CDs

Mixxx can not play music directly from audio CDs. Use a CD ripping program to copy the audio from the CD to files on your computer. It is recommended to save the ripped files in the FLAC format. Many different programs are available to rip CDs, but not every program is capable of saving them to FLAC.
