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 Loading Tracks. Mixxx
imports your music library automatically when it is run for the first time, see
Importing your audio files for more information.
The sidebar on the left contains different collections of music. The track list
view on the right displays the tracks in those collections.

6.2. Library - View and edit your whole collection
The Library displays a sortable list of all the tracks in your
music library.
Customizing the view
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.
Sorting Tracks
Tracks are automatically sorted by the active column. Click on the active
column header to reverse the sort order. Click on another column header to
change the active column.
Multi-Column sorting
Nové ve verzi 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:
Click on the BPM column header -> list is sorted by BPM
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.
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.
Rating tracks
Make sure the Rating column is not hidden. Rate tracks by hovering
over the rating field and clicking the stars.
Track Inline editing
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.
Loading tracks
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
Loading Tracks for detailed information.
Importing tracks
Mixxx imports your music library automatically when it is run for the first
time. Go to the chapter Importing your audio files for detailed information.
Previewing Tracks
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 Previewing Tracks for detailed information.
Cover/Album Art
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:
The first image saved in the track’s ID3v2/Vorbis tags
An image file in the track folder (if there is only one image file there.)
%track-file-base%.jpg in the track directory for %track-file-base%.mp3
%album%.jpg
cover.jpg
front.jpg
album.jpg
folder.jpg
Mixxx supports the following image types: jpg, jpeg, png, gif, bmp
Rescan Library
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.

Poznámka
Most of the context menu items are available in file lists of other
views like Auto DJ, Playlists, and Crates as well.
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.
The features in detail:
Select All button: Selects all tracks in the current view.
Purge button: Purges the selected tracks from the Mixxx library, but does
not remove them from your computer. This will delete all metadata
Mixxx has for a track.

Nové ve verzi 2.0: You can drag tracks from deck to deck.
Tracks can be loaded into a deck in several ways:
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 Using a Keyboard to load the selected track in the library track
table.
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.
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.
To clear the search string hit ESC or click the clear button right next
to the input field.
Hit TAB to cycle between the search and the list of results in the
library. Use the ARROWUP and ARROWDOWN keys to scroll in the
list of results.
Poznámka
If the search input field has focus, the Mixxx keyboard shortcuts are
disabled, see Using a Keyboard.
Search operators allow you to form more complex search queries. They allow you
to limit certain search terms to particular properties of your tracks.
Nové ve verzi 2.0: Adds location, album_artist, and key search keywords. Supports
human-readable time suffixes in time-based search query filters, e.g.
1:30, 1m30s, 1m30, 90, 90s. Supports negative search
filters.
Mixxx supports the following filters:
Text filtering: artist, album, album_artist, genre, title, composer,
comment, key, location
Supports fuzzy matching of key searches. The following example list 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 list all tracks by “Danger” over 3 minutes long that
are rated 4 or 5.
artist:Dangerduration:>3mrating:>=4
Negative search filters. Use the - prefix as negation operator. The
following example would find “hip-hop“ from any year but 1990.
genre:hip-hop-year:1990
Examples for text filtering
Examples for numeric filtering
Examples for duration filtering
artist: “com truise”

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.
Alternatively, select a track from the track list of the Mixxx library, drag the
track to the waveform view of the Preview Deck
and click the Play button next to the waveform.
To display the Preview deck, press CTRL + 4 (Windows/Linux) or
CMD + 4 (Mac).
Mixxx reads relevant metadata from the tracks and displays them in the
library columns. You are free to edit most metadata, and Mixxx offers a number
of different ways to do so. Note that some information can not be edited, such
as bitrate, size, length, type, filename, and location.
Poznámka
Mixxx does not support editing the metadata of many tracks at a time
(bulk editing).
Varování
Changes to a track’s metadata will be saved to the Mixxx library,
but not to the track itself. Mixxx wont touch your audio files
to prevent data loss.
Click on a single track in the library and select Properties
to open the editor. Add or change values in the editable fields, and save your
changes as explained below.
Apply: Accept the changes and leave the editor open.
Cancel: Discard the changes and close the editor.
Previous/Next: Load the previous or next track in the current library
view.
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.
The MusicBrainz wizard in Mixxx allows searching the MusicBrainz database and
applying the results to your tracks.
Click on a single track in the library and select Get Metadata
from MusicBrainz. Mixxx fetches track data from the MusicBrainz database and
displays the search results.
Select the best match from the search results by clicking on it in the list.
Apply: Apply the selected MusicBrainz metadata to the track.
Close: Close the wizard.
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.
Rada
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.
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.
Popular software to edit metadata of audio files include:
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.
The Auto DJ features in detail:
Shuffle button: Randomizes the order of tracks in the Auto DJ playlist.
Add Random button: Add random track from Auto DJ track sources.
Skip track button: Skips the next track in the Auto DJ playlist.
Fade now button: Triggers the transition to the next track.
Transition time spin-box: Determines the duration of the transition. A
negative value will add a pause between tracks.
Enable Auto DJ button: Toggles the Auto DJ mode on or off.
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
Nové ve verzi 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.
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 New playlist. Name the playlist and click
OK.
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.

Duplicate Playlist, name the new playlist and click OK.
Remove: Removes an unlocked playlist. Tracks that were in the playlist
remain in the library for later use.
Lock: This icon indicates a locked playlist. If a playlist
is locked, you cannot add tracks, rename or delete the playlist. Choose
Unlock from the context menu to unlock the playlist.

Import crate: Import tracks from external playlists in various file
formats to a new Mixxx crate.
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.
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.
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.
Nové ve verzi 2.0: Add music directories directly from the Browse sidebar item.
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 or directly to the
Waveform Displays.
Poznámka
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.

access. Click the Browse sidebar item and navigate to the folder you
would like to bookmark. Right-click and choose Add to Quick Links.
The folder is now pinned below the Quick Links. To un-pin that
folder, right-click and choose Remove from Quick Links.
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.
This icon indicates the current session.

to use the data in other applications.
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 - Using external libraries
Nové ve verzi 2.0: Support for Banshee music player
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.
