Description

when I use my custom speed control, it will get different adjusted speed & set the playbackParameters to the SonicAudioProcessor(I need to use Sonic instead of AudioTrackParameters to change playback speed cause API level problem).
When the speed changed too often, the audio will playing with plosive & noise, the faster the speed changes, the worse the audio quality
