Stable Volume

The test bench for the Windows app. Grab the chaos script to fight StableVolume with a real, jumping system volume. Or play with the web version: hold a level, make the sound wobble, and level it back out.

★Test the Windows app with real chaos

A web page can't touch your Windows master volume, so it can't fight StableVolume by itself. This tiny PowerShell script can. It sets your real volume to random levels and mutes it now and then, then tells you whether it stuck.

  1. Open StableVolume, pick a level (say 40%), flip Hold volume.
  2. Open PowerShell, paste the script below, press Enter.
  3. Every line should read now 40%. If it shows the random level, the guard missed it. Your corrections counter in the app should climb too.

Untested on a real Windows machine so far. It uses the same Windows audio API the app watches. Stop it any time with Ctrl+C. It only changes volume and mute, nothing else.

2Sound to test with

Play something, then mess with the volume.

Wobble makes the sound itself jump loud and quiet at random, like a bad video. That is what the leveler below fixes. It does not move your Windows volume.

Demo is a quiet-then-loud melody made on the fly, so you can hear the volume jumps.

Chaos

Pretend apps, hotkeys and drivers are fighting for your volume.

  • Nothing yet. Turn on the guard, then hit Chaos.

3Loudness leveler web-only bonus

Pulls quiet parts up and loud parts down so everything lands near the same loudness. A browser can do this to its own audio. Windows needs a driver for it.

4Self-test

Runs the guard and the leveler through real changes and checks the results. Takes about 25 seconds and plays a quiet demo.

What this can't test: your real Windows system volume. The page only controls its own audio, so the Windows app still needs a try on your laptop. This page checks the logic: hold, cap, keep-unmuted, and snap-back speed.
