Record and play louder volume avaudio

Question

I used the tutorial found here to record and playback a sound. The recording and playback work fine, but I can barely here the sound when I play it back. I've tried the following code:

UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;                
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,          
                             sizeof (audioRouteOverride),&audioRouteOverride); 

I add it to my "play" method, right before I play the sound. I've also tried to add it to my viewDidLoad. Both of them make it so I can't here the playback at all. It seems to be working for others, but where should I add it?

I checked out SpeakHere, Apples example AVAudio app. The volume is very quiet. When I use the Voice Memos app, the recording is played back very very loud. Has anyone been able to play a recorded message and play it back that loud?

Answer 1

Try setting this property of AVAudioPlayer ...

@property float volume; /* The volume for the sound. The nominal range is from 0.0 to 1.0. */
