Raise system audio up to +20 dB while preserving clarity with a limiter, applying EQ and safety limits across apps and outputs. Amplia: Volume Booster & EQ from Quantix Utility Studio runs as a system-wide audio processor on Android devices, showing actual decibel gain with its Honest Numbers display. It bundles a multi-band equalizer, presets, and output-aware profiles, and fits listeners who need louder playback without distortion and those who want measurable control over device gain.

What the app actually does for your playback

Amplia intercepts audio at the system level, which means you don't import files or rebuild libraries to change sound. It applies gain and EQ to audio coming from music players, video apps, games, and calls, so you hear the boosted result in any app. The app reports the real decibel gain applied, so you can see hardware-imposed limits rather than opaque percentage sliders.

How it handles devices and outputs

The tool supports wired headphones, Bluetooth, USB audio, and internal speakers, and it can switch profiles automatically when you connect different outputs. You set an output-aware profile for headphones or Bluetooth, and the app applies the chosen EQ and effects for that route. The Honest Numbers readout helps you confirm how much gain the hardware allows on each output.

Controls, presets, and safety features

The free tier gives a 5-band equalizer, hearing-safety tracking, and up to +9 dB boost; the Pro tier expands to a 10-band EQ, 14 presets, bass boost, and a 3D virtualizer. You can set a safe volume ceiling to prevent prolonged exposure above your threshold, and Night Mode plus Dialogue Clarity address different listening situations without changing the source app.

Performance and audible results

The developer prioritizes a limiter-first chain to avoid clipping, so you get louder output while avoiding the distortion typical of naive boosters. Users report improved sound for streaming and clearer dialogue, and the app works on devices running Android 8.0 and newer. Because it processes audio in real time, heavier effects may tax lower-end devices more than entry-level setups.

Good gateway for listeners who need measurable loudness control

If you want louder, clearer system audio and you value a decibel readout over vague sliders, Amplia is a practical entry point. It gives you direct control of device gain and safer listening options; the trade-off is that extreme boosting still depends on your hardware’s physical limits. Try it when you need measurable volume gains without altering each source app.
