Question

I am writing an application that uses the AVAudioRecorder class. It works great except for when a phone call comes in. I am handling this per apple’s guidelines of using the AVAudioRecorderDelegate methods

– (void) audioRecorderBeginInterruption:
– (void) audioRecorderEndInterruption:

It works great until the interruption ends and I attempt to “resume” the recording by calling the record method again (per the documentation). However it does not resume my recording but instead throws out the old one and starts up an entirely new one in its place. I have not been able to find a solution to this problem, if anyone has figured this out, or if it is a bug with apple’s AVAudioRecorder please let me know. I really hope I do not have to write this using AudioQueues.

thanks

Looks like its a bug with apple’s API. Great fun….

This was the response we received from a support ticket.

“The behavior you described is a bug and unfortunately there’s nothing in the API that you can change to work around to actually append to the original recording. The interruption is resulting in capturing only the audio recorded after the interruption. You could try and stop the recording after the interruption then creating a new file after which would at least not cause the user to loose any information, but the result would be two separate files.

Please file a bug report at for this issue since bugs filed by external developers are critical when iOS engineering is evaluating critical features of fixes to address. It’s easily reproducible but if you have a test app you can include please do, iOS engineering like having apps that show the bug directly.
