About this app

Notch is a system-wide equalizer and audio EQ for your phone. Turn it on once and the same sound settings apply to music, games, videos, and other apps.
Boost bass. Cut harsh highs. Keep it from clipping.
Equalizer
A simple EQ with bass, mid, and treble. Pick a preset or shape your own sound curve. Cut muddy sound, tame harsh frequencies, and boost what you want to hear.
Bass and Clarity
Add deep bass and bass punch. Smooth harsh highs. Make the sound warmer or brighter without a cluttered mixer.
Compressor
Evens out loud and quiet parts so music feels more consistent.
Limiter
Stops sudden volume peaks from distorting. Louder is fine. Crackling is not.
Auto Gain
Keeps the volume steady when you boost the EQ, so the sound does not blow out.
Headphone Equalizer
Wider headphone sound. One switch. Readable controls. No hidden menus.
Notch is an equalizer app for music listeners, headphone users, and anyone who wants one EQ for every app. It also works for voice, podcasts, and a quick mobile mix.
Notch works as a bass booster, volume booster, and headphone equalizer in one app — built for music, podcasts, games, and video. Looking for a system-wide EQ, sound booster, or an audio compressor and limiter for your phone speakers or headphones? This is it.

Cut what doesn’t belong. Keep what does.
