Recording AVAudioPlayer using AVAudioRecorder

Question

In my application, the user plays a sound by pressing a button. There are several buttons that can be played simultaneously. Sounds are played using instances of AVAudioPlayer. I want to record the output of these instances using AVAudioRecorder. I created everything and the file is created and recorded, but when I play it, it does not play sound. This is just a quiet file, record length. Does anyone know if there is a parameter missing from AVAudioPlayer or AVAudioRecorder? Thanks

Answer 1

Writing AVAudioPlayer as an input to AVAudioRecorder for recording is not possible. You can use the sound buffer to store playback files and save it to a file.

Answer 2

It would be easier to help if you saw your code.

You should also check the following link to see if the AVAudioRecorder setting is configured correctly: How do I record audio on iPhone using AVAudioRecorder?

Although this link shows how to set up microphone recording, it may still be useful for you.
