Turn your volume up past 100% — all the way to 500%.
Volume+ is a tiny Windows app that lives in your system tray. Windows caps the volume slider at 100%; Volume+ gives you a second slider that goes 100% → 500%, so quiet videos, calls and games can actually get loud.
- 🔊 Volume 100% → 500% — push your sound past the Windows limit with one slider.
- ⚡ One-click presets — 100 / 200 / 300 / 500%.
- 📌 Lives in the system tray — double-click to open, quiet and out of the way.
- 🚀 Starts automatically with Windows (optional, one click).
- 🔒 No account, no login, no telemetry. 100% local.
Volume+ needs Equalizer APO — a free, open-source Windows audio engine — to actually amplify the sound.
Why? Windows' 100% isn't a lockable limit you can just raise: the volume slider only
attenuates, and the audio engine (audiodg.exe) is a protected process nothing can
inject into. The only native way to go above 100% is a system audio effect (an APO).
Volume+ drives Equalizer APO's engine for you — you never have to touch it.
On first launch, if Equalizer APO isn't installed, Volume+ shows a "Get Equalizer APO" button. Install it, pick your output device, reboot once — then Volume+ takes over.
- Download
VolumePlus.exefrom the Releases page and run it. (Windows SmartScreen may warn because the exe isn't code-signed → "More info" → "Run anyway".) - On first launch, Volume+ walks you through installing Equalizer APO (free) — tick your speakers/headset in its setup, then reboot once.
- Reopen Volume+ and slide it up. That's it.
- Clean on VirusTotal: 0 / 68 detections — VirusTotal indexes by file hash, so this link always shows the current result for this exact
.exe. Scan it yourself anytime. - No account, no telemetry, no network calls — Volume+ only writes a small local config file that tells Equalizer APO how loud to go.
- Single-purpose — one small tool that does exactly one thing.
The exe isn't code-signed (signing certificates cost money), so Windows SmartScreen may warn you the first time — that's normal for indie apps. Click "More info" → "Run anyway".
The Windows volume slider is an attenuator: 100% means "signal untouched", and there's
nothing above it — the endpoint volume API is capped at 1.0, and the audio engine
(audiodg.exe) is a protected process no tool can inject into. The one native place to
add gain is the APO (Audio Processing Object) chain — the same slot sound-card makers
use for their effects.
Volume+ simply sets Equalizer APO's preamp in real time: dragging the slider to N%
applies a gain of 20 · log10(N / 100) dB (200% = +6 dB, 500% ≈ +14 dB), live.
⚠️ Digital gain has no free headroom: at very high settings, already-loud content can clip/distort. Turn Windows' own volume down before you put your headphones on, then bring it up gradually.
Your setting is stored in %AppData%\VolumePlus\config.json.
