Andy,
AudioUnits are merely a plugin format, designed to allow external
audio processing code to be added to a program that has already been
compiled. If you are writing your own (iPhone or other) application,
then you are free to process the samples any way you wish, whether or
not you use AudioUnits or any other external code. I have not
written any iPhone applications yet, but I believe you have access to
audio input and audio output. Your goals can be reached using
AUGraph or other parts of CoreAudio besides AudioUnits.

Sorry if this question has been asked before. Does anyone know of an
official list of Audio Units available on the iPhone?
The CoreAudioOverview.pdf does a nice job listing the audio units
available on Mac OS, but does not list what’s available on iPhone? I
looked through AUComponent.h . I think I might be missing something
because there is an application in the apple store called
“PocketGuitar” that has distortion and delay effects. Yet
kAudioUnitSubType_Distortion is conditionally commented out of the
header file?
#if !TARGET_OS_IPHONE
kAuditoUnitSubType_Delay = ‘dely’,
kAudioUnitSubType_Distortion = ‘dist’,
#else
CoreAudioOverview.pdf says that delay and distortion are only
available on Mac OS and that you can not write audio units for the
iphone. Is there some way to implement effects like distortion by
manipulating the sample values while they are in the audio queue or
using some other technique?
