The Equalizer Pie works starting from Android P.
Please note that this application works only with audio players that notifies about starting audio session. It does not work for global output.
Application lets you adjust the frequency envelope of the sound with 14 bands to enjoy music.
Adjust audio balance between channels (Right/Left)
* 14 bands equalizer
* Audio balance
* Pre amplifier (to boost sound volume)
* 14 presets (Default, Default for Bluetooth headphones, Jazz, Rock, Classic, Pop, Deep-House, Dance, Acoustic, Soft, Ton compensation, Voice, Lounge, Flat).
* Customizable preset
Works perfectly with audio and video players that open audio session. (Google Music, YoutTube Music, Deezer, etc.)
We recommend you to restart player after installing equalizer.
It makes noise sound with bluetooth headphones when any of frequency band summary level (preamp + level of band) is more than 0.
That is why we recommend you to use Preamp and decrease level for bluetooth headphones.
