GUI is based on Omnirom DSP Manager and able to run on most Android devices from 5 to 10 include AOSP, Cyanogenmod, Huawei(arm64), LineageOS, Samsung and recent HTC. This app include many cool features.
This repo is a Android variant of JamesDSP, JDSP4Linux uses core library from current repo.
Multiband, multiresolution dynamic range compander –> A highly tunable multiband dynamic range booster/reducer
Auto Bass Boost –> Frequency detecting bass boost. Effect detect interesting frequency, and adjust gain, bandwidth and cut-off frequency arccordingly
Reverb –> Progenitor 2 (Complicated IIR network)
Interpolating FIR Equalizer and IIR Equalizer –>Both FIR and IIR equalizer yield flat response when the gain is uniform, unlike some competitors
Partitioned Convolver (Auto segmenting convolution) –> Support mono, stereo, full/true stereo(LL, LR, RL, RR) IR
Live programmable DSP –> A effect that can compile EEL code into opcode, and do processing base on the compiled code. The EEL virtual machine had pre-built tons of advanced math routines and DSP function. Including: Basic C String manipulation functions, Linear algebra solver(Least square, inv(), pinv()), Mathematical optimization(linprog(), quadprog(), lsqlin()), polynomial roots solver(roots()), spectral processing(Short-time Fourier Transform), Polyphase filterbank(Constant Q Transform), multi-purpose IIR / FIR filter designer(eqnerror() / firls()), IIR Subbands transform, Direct form FIR filter, Fractional delay line, Polyphase resampler, real time 1D convolution, Autoregressive Burg estimator, simple peak finding algorithm.
More details:EEL2 open source variant
Stereo Widen –> Algorithm detect stereo phase relation in a few spectral region, and enhance the stereo soundstage without affect vocal integrity
Crossfeed –> Include traditional BS2B mode and convolution-based HRTF
Vacuum tube modelling –> Second harmonic generator
Viper DDC (Cascaded Second-Order Sections Form II IIR filterbank)

A: Float32.
A: Convolver is a effect apply convolution(a mathematical operation) on input signal, that perfectly apply user desired response on music, it could simulate physical space.
Effect itself require audio file(.wav/.irs/.flac) to become impulse response source.
For more info: Convolution and Convolution reverb
A: Advanced method(Manual installation)
Effect may get unloaded by Android system if no audio stream for while.
audio_effects.conf is a file specified for system to load effect using known UUID.

Modify SELinux is not required(in most case), let your device become safer. Also, it’s good to customizing your own ROM or even port ROM with JamesDSP. Some device does require SELinux workaround to work correctly
Better contact me by email. Send to james34602@gmail.com
