SoundAura
SoundAura is an open source ambient sound app. It does not include any audio tracks to save on download size, but allows users to add local files from their device and play any (reasonable) number of them concurrently, with individual volume controls for each track. SoundAura can also switch between an audio focus respecting mode, and a ‘play in background’ mode that ignores audio focus rules and allows SoundAura to play audio alongside other apps.

Features
- A library of tracks and/or playlists added from the device’s local files, with individual volume controls for each track.
- User created presets of tracks.
- An automatic stop timer set by long pressing the play/pause button.
- A media notification to control playback when the app is in the background. These controls will appear with other media session controls if ‘play in background’ is turned off, or as a regular notification when ‘play in background’ is turned on.
- A quick settings tile to control playback. If the quick settings tile is in use, the notification can be manually hidden if desired to save notification space.
- Auto-pausing during calls (if the ‘play in background’ setting is turned on, this additionally requires the read phone state permission).
- Automatic stopping or pausing when switching to a new audio device that has a volume of zero (e.g. when switching from a headset to the device’s speaker when the speaker volume is zero).
- No permissions required, except for the read phone state permission for the optional auto-pause during calls when ‘play in background’ is turned on, and the notification permission for Android 13 and up.
