I would like to use SSP for equalizing my car audio system. My iPhone (original) connects to the car system using a dock connector - I have no aux jack input. Ideally I would use SSP to generate pink noise to the dock output while simultaneously capturing input from the Apple headset microphone (original version), or another mic attached to the headset jack.
I performed a simple experiment to see if this might be possible. I first setup my iPhone to produce music on the Apple headset, then connected the car's dock connector. At that point the desired result was achieved, i.e., the music switched from playing on the headset to the car's stereo system. But I am unable to determine if the Apple headset micrphone could be tapped by SSP in this configuration. Would this work, or would the iPhone input also be switched to the dock?
Of course the other option would be to play a CD containing pink noise from my CD player while capturing input using the headset mic.
