Dimitry, if I'm not wrong, Android currently only supports AMR_NB for encoding+decoding, PCM is only supported for decoding so far. And the file encapsulating this type encoding should be 3GPP (audio/3gp is the MIME type which you may need). You can find more information about MediaRecorder in developer.android.com, take care!
