Try to make a real-time voice changer based on phase vocoder algorithm.
The algorithm transforms audio input from time space to frequency domain, modifies some content and transforms back to processed audio out.
It seems that the audio in-output latency is better than my expectation considering the moderate heavy computation and audio driver implementation on my 4 years old phone.
The apk is splited in 2 zip files as the apk size is more than 600K to upload with RuntimePermissions lib (AUDIO_RECORD) in, remove both the .zip extension to unzip. Only arm64_v8a supported which should be fine for most modern phones.
Warning: Headsets must be put on to avoid self-excitation howling, which may hurt hearing.
