Hello,
I'm currently working on a noise monitoring app, and there is some signal processing being done -analog and digital gains throughout the acquisition system mostly- that I can't access or get rid off using solely the methods of the android.media.AudioRecord class.
My feeling is that active noise cancellation or automatic gain control are always done at a lowest level, whatever the chosen options when creating an instance of the forementioned class.
I would like to be able to access these and get the corresponding info or disable them, but I guess this is all manufacturer dependent, and I don't know where to look for.
Any help would be much appreciated.
