Volume Launcher Sound Control

Volume Launcher, sound enhancer, volume & sound launcher, and a real 10-band equalizer in one app. Every control works on the audio already playing - turn up a quiet video, add bass to a song, or make speech clearer, live, in whatever app is playing.
Also, you can use this app as a VOLUME luncher AND VOLUME launcher.
VOLUME CONTROL AND VOLUME BOOSTER
- Media volume control with a precision rotary knob
- Volume booster for when the system maximum is not loud enough
- Boost is capped and limiter-protected, because distortion is not loudness.

10-BAND EQUALIZER AND SOUND ENHANCER
- Real frequency curve with bass booster and treble control
- Voice booster for podcasts, dialogue and audiobooks
- Loudness enhancer, spatial 360 virtualizer, compressor and true peak limiter
- Presets for music, movies, gaming and bass, or save your own EQ curves

AUDIO TOOLS
Spectrum analyzer, sound meter, speaker test, headphone test, stereo balance, speaker cleaner and a 20 Hz to 20 kHz tone generator.

SOUND CONTROL FROM ANYWHERE
Four home screen widgets, a floating sound controller, a Quick Settings tile, and light and dark themes.

WORKS WITH THE APPS YOU ALREADY USE
The equalizer and volume booster attach to your phone's audio output, so they apply to music, video, streaming, podcasts and games on speaker, headphones or Bluetooth. Nothing to import.

HONEST ABOUT LIMITS
Audio effects depend on your device, so the app reports what actually attached on your hardware. This is a listening tool, not a hearing aid.
