[android-developers] AudioRecord weirdness on Samsung Moment (SPH-M900)

Our app has a problem with AudioRecord where the recorded audio is
very sloooow (sound like it's 2x slower). We use
AudioRecord.getMinBufferSize to try 16000 Hz first and then back down
to 8000 Hz if that function returns an error. So my guess is that the
audio is reported as 8000 Hz even though it's really sampling @ 16000
Hz.

It seems that the problem could also be that the output stream is
stereo, not mono. We're passing AudioFormat.CHANNEL_IN_MONO on API
levels 5 and above and AudioFormat.CHANNEL_CONFIGURATION_MONO
(deprecated) on the earlier devices. This seems to be how it works for
AudioTrack. But is this how it works for AudioRecord?
