I am developing an app that uses Core Graphics and Audio Queue Services to generate an image that changes with the input from the iPhone's mic. Some sort of interaction between Core Graphics and Audio Queue Services is killing my frame rate, keeping it at about 10 fps no matter what I do. Profiling with Instruments tells me that my pro...
