Is it possible to read the spectrum data from the currently playing track in iOS? For example, to make an equalizer similar to the one in iTunes?

Apple has a sample program, "aurioTouch," which can display time and frequency domain waveforms.

    thanks, however this uses the microphone input. could you recommend tweaks to the code to get it to read from the device's music player? – miketucker Apr 11 '12 at 08:48
