Looks like you are able to record voice on Nokia 6600 in AMR format. I tried to record it, but couldn't get success. I can record only in wav format. Can you please tell me how you were able to record in AMR format and is it possible to record in buffer (not file). When I do player= Manager.createPlayer("capture://audio?encoding=amr"), it records in GSM format (not AMR).
Anybody successful in recording on Nokia 6620 or Nokia 6630 in AMR or GSM format. They allow me only wav format recording.
