When working with Android SoundPool you can alter the playback rate with the following API and adjusting the rate:
SoundPool play(int soundID, float leftVolume, float rightVolume, int priority, int loop, float rate)
My question is how to do so within the Android oboe library. I know you can set the frequency to a AudioStreamBuilder, but once the stream has been opened, can you then change the rate on the fly?
