Volume Booster - Audio Boost Android

Volume Booster is a free volume booster app for Android that makes quiet audio louder — a sound booster, bass booster and 10-band equalizer for music, videos, podcasts and games.

Boost volume up to 400%, add deeper bass and shape every frequency from one screen. Use this volume booster with your phone speaker, headphones or Bluetooth audio while any media app is playing.

🎚️ A SOUND BOOSTER THAT DOESN'T DISTORT

Most apps just add raw gain. Volume Booster runs a real audio engine, so louder stays clean.

• Multi-band compression lifts quiet detail
• A limiter holds back sudden volume peaks
• Sound Cleanup reduces harshness and distortion
• Noise Reduction cuts background hiss
• Automatic speaker and headphone tuning follows your audio output

Raise the sound booster gradually to find the best balance of loudness and clarity on your device.

Fine-tune your sound with a full 10 band equalizer and bass booster.

This equalizer bass booster gives you warmer music, clearer voices or a brighter mix — your call.
