If your audio interface is not accessible from Mixxx because it is used by other applications via PulseAudio, you may close and restart Mixxx using pasuspender mixxx. See Command line options for an overview of Mixxx’s command line options.

2.2. Importing your audio files

Mixxx 1st run - Choose music library directory dialog

Mixxx running on Windows 10 - Choose music library directory dialog

The first time you run Mixxx, you are asked to select a directory where your music is stored. By default, the dialog points to a location where music files are typically held, but you can select any location on your computer.

Click Select Folder and Mixxx will scan your music library. Depending on the size of your library this could take some time. All the supported music files Mixxx detects will be listed in the Tracks - View and edit your whole collection.

If you want to refresh your library (for example because you added or moved files), you can do this with Library ‣ Rescan Library in the menu. If you want to rescan at every launch, select Preferences ‣ Library ‣ Rescan on startup.

On Windows 7 and 8 the import dialog points to your Windows “Music“ Library, a special-purpose virtual folder. You can not use these virtual folders. Select a regular folder instead, usually “My Music“, like pictured above.

2.3. Analyze your library

Library - Icon Analyze Mixxx automatically analyzes tracks the first time you load them in a deck, nevertheless it is recommended that you analyze them before playing live to ensure the beatgrids are correct. Furthermore, track analysis takes considerable CPU power and might cause skips in the audio — things you surely don’t need while performing.

Once you have imported your music library, press OK on the Preferences window. Go to the Analyze view on the left side panel of the library. This allows you to run beatgrid, key, and ReplayGain detection on tracks in advance. While analyzing, the progress in percentage and total queue length are shown.
