6.2. Biblioteca - Consulta i edita la col·lecció sencera

Library - Icon Library La Biblioteca mostra una llista ordenable de totes les pistes que teniu a la biblioteca.

Personalitzeu la vista

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.

Ordeneu les pistes

Les pistes queden ordenades per la columna activa. Feu clic a la capçalera de la columna activa per a invertir l’ordre. Feu clic en una altra columna per canviar la columna activa.

  • Multi-Column sorting

    Novetat de la versió 2.0.

    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.

Puntueu les pistes

Assegureu-vos que la columna Puntuació no està amagada. Puntueu les pistes fent clic a les estrelles.

Editeu les pistes des de la llista

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.

Carregueu les pistes

To load a track into a deck, you can either drag it to the waveform display or use the context menu. Go to the chapter Càrrega de pistes for detailed information.

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.

Les opcions disponibles:

  • Botó Selecciona-ho tot: Selecciona totes les pistes de la llista.

  • Botó elimina: Elimina les pistes de la Biblioteca del Mixxx, però no les elimina de l’ordinador. Tan sols elimina les metadades que el Mixxx té d’aquesta pista.

6.3. Càrrega de pistes

Novetat de la versió 2.0: You can drag tracks from deck to deck.

Les pistes es poden carregar a un plat de diferents maneres:

  • 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.

  • 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 and drag it to another deck or sampler.

  • 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 Mac OS X, dragging-and-dropping a track from iTunes onto one of Mixxx’s waveform displays will load it into that deck.

6.5. Pre-escolta de pistes

To pre-listen to a track, activate the Preview column in a library view. Clicking the Library - Preview Play 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 Library - Preview Pause icon to stop the playback.

També podeu seleccionar una pista de la Biblioteca del Mixxx, arrossegar-la al gràfic d’ona del reproductor de pre-escolta i prémer el botó Reprodueix del costat del gràfic d’ona.

6.6. Modificació de les metadades dels fitxers d’àudio

El Mixxx llegeix les metadades rellevants de les pistes i els mostra a les columnes de la biblioteca. Podeu editar la majoria de les metadades, i us permet fer-ho de diferents maneres. Algunes dades no es poden canviar, com la taxa de bits, la mida, la durada, el tipus, el nom o la ubicació.

Nota

El Mixxx no permet editar les metadades de múltiples pistes alhora.

Avís

Els canvis a les metadades de la pista es desaran a la Biblioteca del Mixxx, però no al fitxer. El Mixxx no modificarà les vostres pistes per evitar la pèrdua de dades.

6.6.1. Edició manual

Edició en línia:

Feu doble clic en un camp de la Biblioteca. Si el camp és editable, es convertirà en un camp editable. Introduïu el valor i premeu Enter quan estigui llest.

  • Reload Track 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.)

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

6.6.2. Ús de la base de dades d’internet MusicBrainz

Musicbrainz és una enciclopèdia musical de codi obert que emmagatzema metadades musicals i les posa a disposició del públic.

Mixxx library - MusicBrainz Wizard

Biblioteca del Mixxx - Assistent de MusicBrainz

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

Seleccioneu una única pista a la Biblioteca, feu clic amb el botó dret i aneu a Recupera metadades amb el MusicBrainz. Es cercaran les dades a la base de dades del MusicBrainz i es mostraran els resultats.

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

  • Aplica: Aplica les metadades seleccionades a la pista.

  • Tanca: Tanca l’assistent.

  • 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.

Suggerència

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.

6.6.3. Using third-party software

If you have modified file metadata in third-party software, select Library ‣ Rescan Library in the menu on top of the application window. This prompts Mixxx to re-read the metadata from all tracks in the library.

Algunes aplicacions populars d’edició de metadades d’audio són:
  • Mp3tag (Windows, en anglès)

  • Kid3 (Mac, Windows, Linux)

  • Picard (Mac, Windows, Linux, en anglès)

6.7. DJ Automàtic - Mescleu de manera automatitzada

Library - Icon AutoDJ 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.

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

  • Botó Activa el DJ Automàtic: Activa o desactiva el DJ Automàtic.

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

Novetat de la versió 2.0.

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.

6.8. Playlists - Arranging tracks in a set order

Library - Icon Playlist 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.

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

6.9.1. Caixes o llistes de reproducció?

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.

6.10. Navega - Carregueu pistes externes

Library - Icon Browse Browse mode works like a file manager and allows you to load tracks from anywhere on your computer that are not necessarily already in your Mixxx library.

Novetat de la versió 2.0: Afegiu carpetes de música directament des de l’element Navega de la barra lateral.

Click the Browse 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 Library - Icon Library Library icon or directly to the Visualització de gràfics d’ona.

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.

6.13. Analitza - Prepara les pistes

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 Analyze your library for details.

6.14. iTunes, Traktor, Rhythmbox, Banshee - Utilitzant biblioteques externes

Biblioteques compatibles:

Novetat de la versió 2.0: Suport per al reproductor de música Banshee

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.
