Overview
If your PC is too quiet even at 100%, you can amplify the sound using built-in features and third-party tools. This guide covers everything from Windows’ Loudness Equalization to VLC’s 300% boost and dedicated booster apps.
Several methods can boost your PC’s volume beyond the normal maximum.
Warning: Boosting volume well beyond 100% can distort audio and, at high levels, damage speakers or your hearing. Increase gradually and keep levels reasonable.
Key Takeaways
- Check per-app volume and the default playback device first.
- Loudness Equalization (an audio enhancement) raises perceived volume without extra software.
- VLC can play media up to 300% volume.
- Booster apps like Letasoft Sound Booster or Equalizer APO amplify system-wide.
First Checks
1. Make sure the system volume and the app’s own volume are both up.
2. Open Volume mixer (or Quick Settings) and raise the level for the specific app.
3. Confirm the correct Output device is selected in Settings > Sound.
4. Clean dust from laptop speaker grilles, which can muffle sound.
Adjust per-app volume in the Volume mixer / Quick Settings.
Method 1 — Enable Loudness Equalization
1. Press Windows key + R, type mmsys.cpl, and press Enter.
2. On the Playback tab, select your device and click Properties.
3. Open the Enhancements tab.
4. Tick Loudness Equalization, then Apply — this evens out and raises quiet audio.
Note: If there is no Enhancements tab, switch to the Microsoft High Definition Audio driver to expose it (see our guide on restoring the Enhancements tab).
Method 2 — Use VLC Media Player (up to 300%)
1. Open your media in VLC.
2. Drag the volume slider above 100% — VLC allows up to 300%.
3. To raise the default cap, go to Tools > Preferences > Audio and set the maximum volume level.
VLC can boost playback volume up to 300%.
Method 3 — Sound Booster Software
- Letasoft Sound Booster — amplifies system-wide volume above 100%.
- Equalizer APO — a free, powerful system-wide equalizer that can add gain.
- Use reputable tools from their official sites, and raise gain carefully to avoid distortion.
Letasoft Sound Booster amplifies system audio.
Other Fixes
- Run the audio troubleshooter (Settings > System > Troubleshoot).
- Update or reinstall the audio driver from Device Manager or the manufacturer.
- Try a different playback device or external speakers/headphones for more output.
Troubleshooting
Problem: Audio distorts when boosted.
Solution: Lower the boost level; amplifying too far clips the signal. Loudness Equalization is gentler than raw gain.
Problem: No Enhancements tab for Loudness Equalization.
Solution: Switch to the Microsoft High Definition Audio driver, which exposes the Enhancements tab.
Problem: Boost only works in one app.
Solution: Use a system-wide tool like Equalizer APO or Letasoft Sound Booster to amplify all audio.
Problem: Still too quiet.
Solution: The speakers may be underpowered. Use external speakers or headphones, or an amplifier/DAC for more output.
Conclusion
You can push Windows audio past 100% with Loudness Equalization, VLC’s 300% slider, or a trusted booster app. Increase gradually to avoid distortion and protect your speakers and hearing.
