I have simplified my question and offered a bounty: What options are there for compressing raw PCM audio data to a mp3 on a Android device.

My original post: I'm creating a synthesiser on my Android phone, and I've been generating PCM data to send to the speakers. Now I'm wondering if I can encode this PCM data as a mp3 to save to the sdcard. The MediaRecorder object can encode audio coming from the microphone into various formats, but doesn't allow the encoding from programmatically generated audio data.

So my question is, is there a standard Android API for encoding audio? If not, what pure Java or NDK based solutions are there? And can you recommend any of them?

Failing this I'll just have to save my generated audio as a WAV file, which I can easily do.
