Trouble storing Audio on Parse in an m4a format

I am trying to record audio using the amazing audio engine and then upload it to Parse.

There is a great question on stackoverflow which seems to deal with this here but I am having problems with the m4a formatting side of things meaning this answer doesn't help me.

This is how I record audio:

self.recorder = [[AERecorder alloc] initWithAudioController:_audioController];

NSArray * documentsFolders = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * path = [documentsFolders[0] stringByAppendingPathComponent:@"Recording.aiff"];

And then how I save it to Parse:

NSArray * documentsFolders = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * path = [documentsFolders[0] stringByAppendingPathComponent:@"Recording.aiff"];

NSData * audioData = [NSData dataWithContentsOfURL:[NSURL fileURLWithPath:path]];

PFObject * testObject = [PFObject objectWithClassName:@"TestObject"];

PFFile * audioFile = [PFFile fileWithName:@"audio.aiff" data:audioData];

testObject[@"audioFile"] = audioFile;
[testObject saveInBackground];

This all works fine and the audio is uploaded and saved correctly.

The problem is that I am saving the audio in an aiff format, this means it takes longer to stream and upload as it is a larger file. I really want to save the audio in an m4a format as speed is more of an issue than quality.

I find though when I change .aiff to .m4a suddenly it doesn't work.

Is there something I am doing wrong or overlooking? I feel that this should be a quick an easy change so any advise would be greatly appreciated.

Can you try telling the AERecorder to use M4A format and see if that helps (in addition to changing the filenames.)

[self.recorder prepareRecordingToFileAtPath:path fileType:kAudioFileM4AType error:nil];

Or setting that fileType in beginRecording.
