Accessing microphone from a service on Glass

Question

I would like a service to access the microphone (and do some signal processing on it a bit like what the google music is doing to recognise songs) Is there a public API for that ? can't seem to find it :/

Answer 1

Have you tried the AudioRecord class in Android? That should do everything you need. You might also find the waveform sample on the Google Glass GitHub page to be a useful example.

Keep in mind that recording audio from a service (as in a background service) might be dangerous since other applications could need the microphone for voice recognition and so forth. Using an immersion for this might be a better approach.
