Auxio is a local music player with a fast, reliable UI/UX without the many useless features present in other music players. Built off of ExoPlayer, Auxio has superior library support and listening quality compared to other apps that use outdated android functionality. In short, It plays music.

I primarily built Auxio for myself, but you can use it too, I guess.

The default branch is the development version of the repository. For a stable version, see the master branch.



  • ExoPlayer-based playback
  • Snappy UI derived from the latest Material Design guidelines
  • Opinionated UX that prioritizes ease of use over edge cases
  • Customizable behavior
  • Support for disc numbers, multiple artists, release types, precise/original dates, sort tags, and more
  • Advanced artist system that unifies artists and album artists
  • SD Card-aware folder management
  • Reliable playlisting functionality
  • Playback state persistence
  • Full ReplayGain support (On MP3, FLAC, OGG, OPUS, and MP4 files)
  • External equalizer support (ex. Wavelet)
  • Edge-to-edge
  • Embedded covers support
  • Search functionality
  • Headset autoplay
  • Stylish widgets that automatically adapt to their size
  • Completely private and offline
  • No rounded album covers (Unless you want them. Then you can.)


  • Storage (READ_MEDIA_AUDIO, READ_EXTERNAL_STORAGE) to read and play your media files
  • Services (FOREGROUND_SERVICE, WAKE_LOCK) to keep the music playing even if the app itself is in background


Auxio relies on a custom version of ExoPlayer that enables some extra features. This adds some caveats to the build process:

  1. cmake and ninja-build must be installed before building the project.
  2. The project uses submodules, so when cloning initially, use git clone --recurse-submodules to properly download the external code.
  3. You are unable to build this project on windows, as the custom ExoPlayer build runs shell scripts that will only work on unix-based systems.


Auxio accepts most contributions as long as they follow the Contribution Guidelines.

However, feature additions and major UI changes are less likely to be accepted. See Why Are These Features Missing? for more information.
