Quick answer

Mix looping ambient sounds, each at its own volume. Offline, free, no ads.

F-Droid repository metadata

Soundboard mixes looping sounds from your own audio files. Play any number of them at the same time and set each one's volume independently — rain under a fan under a cafe, at whatever balance you like. Built for tabletop-gaming ambience and for sleep soundscapes, but it will loop anything you point it at. What it does * Add sounds with the + button. The system file picker accepts a multi-selection, so a whole folder of ambience lands in one go. * Play any combination at once. Each row has its own play/pause toggle, and sounds loop until you stop them. * Set each sound's volume by tapping its volume pill and dragging around the dial. The percentage is relative: your device's volume keys still move the whole mix together, and each sound keeps its balance within it. * Keeps playing in the background with the screen off. A notification shows how many sounds are running and offers "Stop all". * Reorder, rename, and sort the board to taste. Your files stay yours Soundboard never copies or moves your audio. It remembers where each file is and reads it in place, using only the per-file permission you granted when you picked it. It never asks for broad storage access. Private by construction The app requests no INTERNET permission at all, so it cannot phone home even by accident. No account, no network calls, no telemetry, no ads, no tracking. Free software Released under the GNU General Public License v3 by 508.dev, a worker-owned software co-op. The source is on GitHub — read it, build it, change it.

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
