YetAnotherVolumeBooster is a lightweight Windows utility that increases shared-mode system audio beyond the normal 100% limit. It provides a polished 100–500% gain controller while using Equalizer APO as the underlying Windows Audio Processing Object.
It is designed to feel like a small native Windows utility rather than a full equalizer suite: install it once, select your playback device, and control the boost from the main window or system tray.
Important
YetAnotherVolumeBooster does not install its own background service. Equalizer APO runs inside the Windows audio engine. A true app exit resets YetAnotherVolumeBooster's managed gain to 100% / 0.00 dB. Closing to the tray intentionally keeps the selected boost active.
- 100–500% system-wide gain for normal Windows shared-mode audio
- Smooth precision slider with direct 100%, 200%, 300%, 400%, and 500% presets
- Automatic Windows master-volume synchronization when boost is above 100%
- Emerald light and dark themes with a circular theme-switch animation
- Native anti-aliased interface with rounded cards, switches, and controls
- System tray controls for quickly changing gain without opening the window
- Start with Windows option that launches quietly into the tray
- Close-to-tray option with a separate true Exit command
- Live Equalizer APO configuration updates without restarting the player
- Device Setup and Repair Integration tools built into the app
- Diagnostic logs for controller, installer, APO integration, and device-selector failures
- Safe exit behavior that restores 0 dB before terminating
- No Python, .NET, Electron, or browser runtime required
- Native Windows x64 executables built with Go
YetAnotherVolumeBooster displays a linear amplitude multiplier and converts it to Equalizer APO preamp gain:
| YetAnotherVolumeBooster | APO gain |
|---|---|
| 100% | 0.00 dB |
| 200% | +6.02 dB |
| 300% | +9.54 dB |
| 400% | +12.04 dB |
| 500% | +13.98 dB |
Caution
High gain can clip already-loud audio, damage speakers or headphones, and harm your hearing. Begin at 100%, increase gradually, and lower the level immediately if you hear distortion.
- Windows 10 or Windows 11
- 64-bit Windows installation
- Administrator access during setup
- A playback device that supports Windows audio enhancements/APOs
- Shared-mode audio playback
ASIO and WASAPI exclusive-mode applications may bypass the Windows APO pipeline and therefore may not be affected by YetAnotherVolumeBooster.
- Open the repository's Releases page.
- Download
YetAnotherVolumeBoosterSetup.exefrom the latest release. - Run the installer and approve the Windows administrator prompt.
- Confirm the installation when prompted.
- If Equalizer APO is not already installed, YetAnotherVolumeBooster will:
- download the official Equalizer APO 1.4.2 x64 installer;
- verify its SHA-256 checksum before execution; and
- install it automatically.
- In the Equalizer APO device selector, select the actual speakers, headphones, Bluetooth device, USB DAC, or monitor output you use.
- Click OK in the device selector.
- Restart Windows if setup says the Windows Audio service could not be restarted automatically.
- Open YetAnotherVolumeBooster and compare 100% with 200% while audio is playing.
Community builds may be unsigned and can trigger a Microsoft Defender SmartScreen warning. Download YetAnotherVolumeBooster only from this repository's Releases page and compare the file checksum with the release notes when one is provided.
Drag the slider or select one of the preset buttons. Values above 100% set the active Windows playback endpoint to its maximum volume and then apply additional APO gain.
The status card reports the active state, for example:
Active · Windows 100% · APO +6.02 dB
The tray menu provides:
- Open YetAnotherVolumeBooster
- 100%, 200%, 300%, 400%, and 500% presets
- Start with Windows toggle
- Close button minimizes to tray toggle
- Exit
Left-click or double-click the tray icon to reopen the window.
| Action | Result |
|---|---|
| Click X with close-to-tray enabled | Window hides; app and selected gain stay active |
| Click X with close-to-tray disabled | Gain resets to 100%; app exits |
| Select Exit from the tray menu | Gain resets to 100%; app exits |
| Windows startup enabled | App starts quietly in the tray |
YetAnotherVolumeBooster.exe
│
├─ sets the active Windows playback endpoint to 100% when needed
│
└─ writes a managed preamp value to:
C:\Program Files\EqualizerAPO\config\YetAnotherVolumeBooster\gain.txt
│
└─ Equalizer APO reloads the configuration
and processes shared-mode Windows audio
YetAnotherVolumeBooster adds one managed block to Equalizer APO's main configuration:
# BEGIN YetAnotherVolumeBooster
Include: YetAnotherVolumeBooster\gain.txt
# END YetAnotherVolumeBooster
Existing Equalizer APO configuration is preserved, and the installer creates a backup before modifying config.txt.
- Download the newest
YetAnotherVolumeBoosterSetup.exe. - Run it over the existing installation.
- Confirm the active playback device if the device selector opens.
- Restart Windows only if requested.
Your user preferences and managed gain configuration are preserved during a normal update.
- Open Windows Settings → Apps → Installed apps.
- Find YetAnotherVolumeBooster.
- Select Uninstall and confirm.
The uninstaller removes YetAnotherVolumeBooster, its shortcuts, startup entry, managed APO include, gain file, and ProgramData diagnostic logs. Equalizer APO is intentionally left installed to avoid damaging unrelated audio configurations. Remove Equalizer APO separately from Windows Settings only when no other application or configuration uses it. To remove saved UI preferences as well, delete %APPDATA%\YetAnotherVolumeBooster.
- Open Device Setup and confirm that the currently active playback device is selected.
- Make sure Windows is outputting audio through that same device.
- Restart Windows once after selecting a new device.
- Confirm that audio enhancements are not disabled for the playback device.
- Test with a normal shared-mode app such as a browser, media player, or Spotify desktop.
- ASIO and WASAPI exclusive-mode applications can bypass Equalizer APO.
- Use Repair Integration to rebuild the managed configuration and reopen the device selector.
The displayed percentage is an amplitude multiplier, not a perceived-loudness measurement. Human loudness perception is logarithmic, and source material may already be normalized, limited, or mastered near full scale. Higher gain may create clipping before it produces a clean perceived-volume increase.
The Close button minimizes to tray setting is enabled. Use Exit from the tray icon, or disable that setting before clicking X. A true exit resets the managed preamp to 0.00 dB.
Run Repair Integration from YetAnotherVolumeBooster. The repair launcher isolates Equalizer APO's Qt environment, verifies the platform plugin, and records detailed diagnostics if the selector still fails.
Check the Windows notification-area overflow menu. If YetAnotherVolumeBooster is running but the icon is not visible, end YetAnotherVolumeBooster.exe in Task Manager and launch it again from the Start menu.
Use the Logs button in YetAnotherVolumeBooster, or open:
C:\ProgramData\YetAnotherVolumeBooster\logs\YetAnotherVolumeBooster.log
C:\ProgramData\YetAnotherVolumeBooster\logs\YetAnotherVolumeBoosterSetup.log
When reporting a bug, attach both files and include:

- The YetAnotherVolumeBooster percentage tested
- Whether a Windows restart was performed after device setup
- Windows 10/11 x64
- Go 1.23 or newer
- PowerShell
