I am trying to implement audio analysis for my application (i.e. for a visualizer or something else). Using the Audio Queue structure, can I read the result of playing itunes against the background of the device into the AudioQueueLevelMeterState variable? Once I have this variable, I can do everything I need, I just can’t figure out how to get this information. All the samples that I looked at are read either from the internal sound of your application or from the microphone input. To make my application as simple as possible, I would prefer the user to customize any music they want on itunes and just play in the background when loading my application ...
Forgive me if this question has already been answered many times, but I just need a good guide from which to start researching this solution. Thank...
