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. <b>What it does</b> * 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. <b>Your files stay yours</b> 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. <b>Private by construction</b> 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. <b>Free software</b> Released under the GNU General Public License v3 by 508.dev, a worker-owned software co-op.
