I use AudioRecord class to get microphone audio samples and AudioTrack to play them back. Is there any way to completely stop or bypass any kind of preprocessing the phone does to the microphone input samples, or to the output samples?I have looked at all the sound related settings on the phone and they are all disabled, at least as far as I can tell. I think some kind of built in noise reduction or some other effect is kicking in when I blow into the microphone However, if I blow into the microphone, I can momentarily notice the sound in the earphone going smaller, which slowly rises back to its normal volume Normally I can hear what I say into the microphone loud and clear on the attached headphone I have made a program that reads a fixed number of bytes from the microphone and sends it out to the speaker, effectively a program to route audio from the mic to speaker without any changes
