You drag past 100%
Every app has its own slider. Up to 100% it's plain Windows volume. Past the notch, VolumeX takes over.

Louder than 100%.
Louder than 100%.
One app at a time.
VolumeX boosts any app, or your whole PC, past Windows' 100% limit, without the crackle. Everything you don't boost plays exactly as before.

Drag past 100%.
This is what VolumeX does for one app. Press play, then push the slider into the boost zone. Switch the Distortion Guard off to hear why it's there.
Press play - and start with your volume low.

How it works
Three steps, only for the apps you boost.
Only that app takes the boost path
A boosted app plays through VB-CABLE, a free virtual device by VB-Audio. Everything else goes straight to your speakers, with no delay added.
Louder, never crunchier
The engine raises the level, and the Distortion Guard, a look-ahead limiter, catches every peak before it can clip.
Features
Everything Windows' mixer should have been.
Every app, its own boost
Chrome at 220%, Spotify at 45% and Discord at 135%, all at once. Each app gets a slider up to 300% (500% if you unlock it), with a live level meter built in.
Boost what you're using
One hotkey raises whichever app is in front, from anywhere. A small overlay shows the new level.
0ms
Added to everything else
Apps you don't boost never touch VolumeX's audio path.
One dial for the whole PC
Up to 100% it's your normal Windows volume. Keep turning to boost everything, or tap a preset: 150%, 200%, 300%.
Lives in your tray
Click the icon for a quick mixer. It turns orange while something is boosted.
Remembers every app
Windows often forgets your levels. VolumeX puts them back every time an app starts, and runs rules like "when Zoom starts, turn Spotify down to 30%".
A boost per device
Headphones at 180%, speakers at 100%. VolumeX remembers the master boost for each output and applies it when you switch.
Never leaves your audio broken
Every change is written down before it's made, then undone on quit, crash or uninstall. No code injection, so it's safe to run alongside games with anti-cheat.
Take the tour
Every screen, one click away.
Safety
Loud, not reckless.

VolumeX doesn't talk to the internet. The one exception: if you ask it to install VB-CABLE and the copy that ships with it is missing, it downloads VB-Audio's official package, checks its signature and runs nothing else.
Your ears matter too. Levels change smoothly and never jump, the first boost comes with a hearing note, and the Distortion Guard is on by default. Don't take our word for any of this: read the code.
Get started
Set up in about two minutes.

Install
Run
VolumeX-Setup.exe. VolumeX installs just for you, with no admin prompt. - 02
Keep VB-CABLE ticked
Setup adds VB-CABLE by VB-Audio. Windows asks for permission once, then restart your PC.

Drag past 100%
Open VolumeX from the tray and boost whatever is too quiet. That's it.
