508.dev Soundboard 앱
Soundboard mixes looping sounds from your own audio files. Play any number ofthem 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.
