Editor's Overview

508.dev Soundboard is a ambient sound application developed by 508.dev, packaged as a single Android APK of version 0.1 weighing in at 2.11 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 2.11 MB, so it installs quickly even on modest connections.
This build is signed by "508.dev" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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.
