In my app,I want to make sure user can record his sound and sent to other user to listen to it.
In android platform I choose .amr ,it's not too big and easy to record.
Then I realized I should make sure my ios user can chat with my android user,but .amr seems not support in ios(after v4.3).
So is there a certain audio file format that can use between android and ios platform?
Or I have to let my Server to do the Transcoding job?
