RootlessJamesDSP

Use JamesDSP as a system-wide audio processing engine without any root access.

This app has several limitations that may be deal-breaking to some people; please read this whole document before using the app. Shizuku (Android 11+) or ADB access via a computer is required for the initial setup.

JamesDSP supports the following audio effects:

* Limiter control

* Output gain control

* Auto dynamic range compressor

* Dynamic bass boost

* Interpolating FIR equalizer

* Arbitrary response equalizer (Graphic EQ)

* ViPER-DDC

* Convolver

* Live-programmable DSP (scripting engine for audio effects)

* Analog modelling

* Soundstage wideness

* Crossfeed

* Virtual room effect (reverb)

Additionally, this app integrates directly with AutoEQ. Using AutoEQ integration, you can search and import frequency responses that aim to correct your headphone to a neutral sound. Go to 'Arbitrary response equalizer > Magnitude response > AutoEQ profiles' to get started.

--- Limitations

* Apps blocking internal audio capture remain unprocessed (e.g., Spotify, Google Chrome)

* Apps using some types of HW-accelerated playback may cause issues and need to be manually excluded (e.g., some Unity games)
