Is Android capable of managing microphone/input vo

Question

I've searched everywhere, including the RootTools source. I can't find anything that manages the microphone, apart from muting it altogether. And there are no hints inside the AudioRecorder.setMicrophoneMute(bool) method either...

There are a few posts about this issue, but none of them ever go anywhere (through no fault of OPs'). Is it (legally) possible to override the OS and get to the mic hardware directly or something?

Thanks,

You can't directly set the recording volume, but you can change what you do with the byte data you get from AudioRecord (look at the AudioTrack class for reducing the volume of the track)

Edit: I forgot to mention that if you're having trouble with volume spikes you can look at automatic gain control. Some devices activate it automatically, but you can manually enable it.
