About this app

An offline Android app for mixing looping sounds. Pick audio files from your device, play any number of them at the same time, and set each one's volume independently — rain under a fan under a café, at whatever balance you like.

- **Add sounds** with the `+` button. The system file picker opens and accepts a multi-selection, so a whole folder of ambience lands in one go. The files themselves are never copied or moved — Soundboard just remembers where they are.
- **Play any combination at once.** Each row has its own play/pause toggle, and sounds loop until you stop them. Tapping anywhere on a row toggles it too.
- **Set each sound's volume** by tapping its volume pill, then 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".
- **Remove a sound** by long-pressing its row and choosing Delete. This only takes it off the board — your audio file is left exactly where it is.
