4.2. Tracks - View and edit your whole collection¶
A sortable list of all the tracks in your music library.
- Prilagajanje prikaza
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.
- Sortiranje skladb
Skladbe se samodejno sortirajo po aktivnem stolpcu. Za obratni vrstni red kliknite na glavo stolpca. Za zamenjavo aktivnega stolpca kliknite na njegovo glavo.
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.
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.
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).
- Ocenjevanje skladb
Poskrbite, da stolpec ocenjevanje ni skrit. Za ocenjevanje skladb kurzor premaknite nad polje za ocenjevanje in kliknite na ustrezno zvezdico.
- Neposredno urejanje podatkov o skladbi
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.
- Nalaganje skladb
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 Loading Tracks for detailed information.
- Importing tracks
Mixxx samodejno uvozi vašo glasbeno zbirko ob prvem zagonu. Pojdite na poglavje Changing music directories za podrobnejše informacije.
- 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%.jpgin the track directory for
Mixxx supports the following image types: jpg, jpeg, png, gif, bmp
- Preglej zbirko
If you want to manually refresh your library without exiting (for example because you added or moved files) you can do this within the menu at the top of the application window. You can prompt an automatic rescan when Mixxx is started under .
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.
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:
Izberi vse gumb: Izbere vse skladbe v trenutnem pogledu.
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.
4.3. Loading Tracks¶
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 Uporaba tipkovnice 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. Finding Tracks (Search)¶
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 ↑ and ↓ keys to scroll in the list of results.
If the search input field has focus, the Mixxx keyboard shortcuts are disabled, see Uporaba tipkovnice.
The Computer and Recording views currently only support simple case-insensitive filtering.
Using search operators¶
Search operators allow you to form more complex search queries. They allow you to limit certain search terms to particular properties of your tracks.
Mixxx supports the following filters:
Text filtering: album_artist, album, artist, comment, composer, crate, genre, grouping, location, title
artist: “com truise” album:Danger genre: Trance title: foo composer: foo comment: foo genre:hip-hop -genre:gangsta
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
bpm:140 bpm: >140 year: <2010 bpm: >=140 rating: <=4 bpm: 140-150 played: >10
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.
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
Negative search filters. Use the
-prefix as negation operator. The following example would find “hip-hop“ from any year but 1990.
Search for empty fields. The following example lists all tracks without a genre. It works for all text fields, including crates.
duration:2m10 duration:<2:10 duration:>1m35s duration:>62
You can put a space after the colon but currently there must be no space between the operator and the number.
4.5. Previewing Tracks¶
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).
Click on the Preview column header to randomly sort tracks.
4.6. Edit metadata of audio files¶
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.
Mixxx does not support editing the metadata of many tracks at a time (bulk editing).
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.
- Track Inline editing:
To enable inline editing in the library go to 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.
- Properties editor:
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.
OK: Accept the changes and close the editor.
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.
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.
Using the MusicBrainz online database¶
MusicBrainz is an open-source music encyclopedia that collects music metadata and makes it available to the public.
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.
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.
Rescanning the library within 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.
4.7. Auto DJ - Automate your mix¶
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: 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.
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.
Selection Info label: Displays the duration and number of selected tracks. Press Ctrl + A to get the total duration of the AutoDJ queue.
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 .
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.
For more information, go to the chapter 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.
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:
Add to Auto DJ: Adds the content of the playlist to the Auto DJ queue for automatic mixing.
Rename: To rename a playlist, just enter a new playlist name and click OK.
Duplicate: Sometimes you want to build a playlist based on an existing one. Select the playlist you would like to duplicate, choose 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.
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
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.
Right-click on an existing crate’s name to access the different features in the context menu:
Rename: To rename a crate, enter the new crate name and click OK.
Duplicate: Just like playlists you can duplicate an existing crate. Select the crate you would like to duplicate, choose Duplicate Crate, name the new crate and click OK.
Remove: Removes an unlocked crate. Tracks in the crate are still available in the library for later use.
Lock: This icon indicates a locked crate. If a crate is locked, you cannot add tracks, rename or delete the crate. Choose Unlock from the context menu to unlock the crate.
Auto DJ Track Source: Use this crate as a source for random tracks in Auto DJ, see Auto DJ crates .
Analyze entire crate: Forces the analysis of the crate in the Analyze view.
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
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.
Crates vs. Playlists¶
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 Prikaz valovne oblike.
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.
For more information, go to Changing music directories.
Quick Links - Bookmark your favorite folders¶
Using the Quick Links sub-menu you can bookmark folders for direct access. Click the Computer 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.
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.
For more information, go to Snemanje miksa.
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.
This icon indicates the current session.
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:
Add to Auto DJ: Adds the content of the session to the Auto DJ queue for automatic mixing.
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. Analyze - Prepare your tracks¶
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 Analiza zbirke for details.
4.14. Using libraries from other software¶
iTunes (Windows, macOS)
Traktor (Windows, macOS)
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.
Playing a track from an external library will add it to your Mixxx library.
External libraries can be disabled under.
Using the iTunes/Traktor/Rhythmbox/Bashee/Rekordbox library¶
Right-click on the iTunes icon in the Library tree and select
Choose Library to load the
iTunes Music Library.xml from a
different location. Select Use Default Library to reset.
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.
Plug your USB or SD drive in while Mixxx is running.
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).
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:
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, saved loops, 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.
Waveforms, Gain values and „Flips“ are not imported from Serato.
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:
Copy music library from Serato into external USB drive
Plug in USB drive while Mixxx is running
Click on Serato in the library. All USB drives containing a Serato library will be detected automatically.
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.
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
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.
Click the Library item in the sidebar.
Find and select the tracks you want to remove, perform a right-click on them and select Hide from Library from the context menu.
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.
Select the tracks you want to remove, or use the Select All button.
To confirm you want to permanently remove these tracks from the library, click Purge.
If you want to hide or purge only tracks from a specific folder you may use
location: search operator, or
sort the table by „Location“.
Če se nakndano odločite, da bi radi povrnili del izbrisanih skladb, jih ponovno uvozite v Mixxx knjižnico. Glej: Changing music directories.
4.16. Compatible file formats¶
Mixxx supports a variety of audio file formats:
Ogg Vorbis (ogg)
Aiff (aiff, aif)
AAC (aac, m4a, mp4)
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.
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
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.
AAC playback is disabled by default due to licensing restrictions.
To enable the playback of
build Mixxx from source with m4a/AAC files support.
DRM protected files, such as m4p files purchased in the iTunes Store in 2009 or earlier, are not supported.
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
