I haven’t looked into it much but I did recall that someone was able to use their ipod library music to create a rhythm game using AVAsset.
Take a look into into that to see if it helps you.

Yeah music played through iTunes does not go through AVAudioPlayer so metering can’t be done.

So, is there no way to run the metering code with a song played from the itunes library?

Thanks!

As of right now the way to play music off of the devices library is through the MPMediaPickerController. It’s quite an easy class to setup and get music running. Unfortunately the class does not connect itself with the AVAudioFoundation class which is what we’re using to run the metering code in this post but it if that’s not what you’re looking for then that is the best solution.

Hi
I just needed to resetMetering after starting the background music.
Something like:

[[SimpleAudioEngine sharedEngine] playBackgroundMusic:fullPath loop:YES];
[[AudioVisualization sharedAV] resetMetering];
[[AudioVisualization sharedAV] addDelegate:self forChannel:0];

Thanks!
Regards
Ahsan

Logically it should be as simple as adding the instance since addDelegate places the instance into a list and that list is used to notify everyone. There shouldn’t really be any other needed steps.

Hi Lam

I am facing the problem when I remove the delegate and add the delegate again! I get level = 0.0 in avAvgPowerLevelDidChange.

Do I need to do something after removing the delegate and before adding it again?

Thanks
