 ERROR: >aq> 327: AudioConverterNew from AudioQueueNew returned 'fmt?' io: 1 ch, 8000 Hz, Float32 client: 1 ch, 8000 Hz, 'samr' (0x00000000) 0 bits/channel, 0 bytes/packet, 2400 frames/packet, 0 bytes/frame 

Answer 1

The AMR codec was removed from iOS in version 3.2 (I think). Oh no, 4.3 (thanks, Eric D.). The only link I've ever met was in dev forums (login required).

The strange thing is, while kAudioFormatAMR was removed in iOS 4.3, it looks like kAudioFormatAMR_WB was added in OSX 10.10 (Yosemite) .
