Record AVAudioPlayer output using AVAudioRecorder

Question

In my app the user plays a sound by pressing a button. There are several buttons which can be played simultaneously. The sounds are played using AVAudioPlayer instances. I w

Answer 1

Was facing the same problem. Solved the problem by setting the AVAudioSession category to AVAudioSessionCategoryPlayback mode. This is my working code:

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
audioSession.delegate = self;
[audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
[audioSession setActive: YES error: nil];

Also make sure that the audio recording has been finished successfully by implementing:

   -(void) audioRecorderDidFinishRecording:(AVAudioRecorder *)recorder successfully:(BOOL)flag
{
    NSLog(@"Recording success:%@",flag ? @"YES" : @"NO");
}

And check that you have added <AVAudioSessionDelegate,AVAudioRecorderDelegate,AVAudioPlayerDelegate>

in your interface declaration.

Answer 2

It is not possible to record AVAudioPlayer output as input to AVAudioRecorder for recording. You can use audio buffer to store played files and save it to a file.

Answer 3

It would probably be easier to help if we saw your code.

You should also check out the following link to see if you have your AVAudioRecorder setup correctly: How do I record audio on iPhone with AVAudioRecorder?

Although that link shows how to setup a recording from the mic, it might still be helpful to you.

Answer 4

Hope it helps, at least to look for something else.

I'm having the same issue here, I'm trying to record a mix of different sounds played at different times with a main track playing, what I found is that AVAudioRecorder records only from the mic, so it would work.

What I found, still have to read doc and test it, is the Audio Converter Services, I think that may work, but I have just read a few lines.

Once again, sorry to tell you, but you're looking the wrong way, I hope my answer helps
