Volume Booster - Audio Boost

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.

🔊 BOOST VOLUME UP TO 400%

Need louder music, clearer podcasts or stronger video sound? The built-in volume amplifier raises media audio past your device's normal maximum.

• Increase phone volume up to 400%
• Control the sound booster with a large analog-style dial
• Jump to Mute, 30%, 60%, 100%, 125%, 150%, 250% or 400%
• Adjust system volume and extra boost separately
• Watch audio activity on the live level meter
• Your last volume booster level is remembered

🎚️ 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.

🎛️ 10-BAND EQUALIZER & BASS BOOSTER

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

• Adjust individual frequencies for bass, mids and treble
• Equalizer presets: Normal, Classical, Dance, Flat, Folk, Heavy Metal, Hip Hop, Jazz, Pop, Rock
• Save custom bass boost equalizer settings and name them
• Turn the Bass Boost knob for a deeper low end
• Super Bass for an even stronger bass booster effect
• Virtualizer for wider stereo, Reverb for a more spacious sound
• Return to flat sound in one tap

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

Maximum boost, sound quality and available effects depend on your device, Android version, audio output and the app playing the audio.
