Audio is delivered to applications using the standard Android mechanisms, so an application that records audio should work out of the box on a HMT-1.
It is possible to record audio in mono or stereo at the following sample rates:
The WearHF service handles microphone selection automatically and audio delivered to an application after the HMT-1 has preformed noise cancellation, so an application simply needs to record from the microphone.
int bufferSize = AudioRecord.getMinBufferSize(
mSampleRate, monoOrStereo, AudioFormat.ENCODING_PCM_16BIT);
AudioRecord audioRecorder = new AudioRecord(
MediaRecorder.AudioSource.MIC,
8000, // Sample rate
AudioFormat.CHANNEL_IN_STEREO,
AudioFormat.ENCODING_PCM_16BIT,
bufferSize);
mAudioRecorder.startRecording();
