In my application I want to record a video with music playing in background. I have achieved this through AVCaptureSession and AVAudioSession.
After recording (through headset) my music file output will be a combination of the sound recorded through mic + the background music played through the speaker. But my issue is that the sound of the background music played through the speaker is very low on the final output music.
I have gone through AVCaptureSession and background audio iOS 7 and added the below code in my viewDidLoad, but with no change in volume.
AVAudioSession *session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryPlayAndRecord withOptions:AVAudioSessionCategoryOptionMixWithOthers|AVAudioSessionCategoryOptionDefaultToSpeaker error:nil];
How can I increase the volume of the background music in my final output?
