There are a couple of shareware apps that slow down audio so you can
play along with it; I think one's called "The Amazing Slow-Downer" or
something like that. I don't know if they support looping and keyboard
control, though.
I'm thinking that I can get most of "Basic" done using QTKit, while
I might have to wrap CoreAudio in Objective-C++ to get AUTimePitch
into the situation? (and how to keep audio/video in sync when
slowing and slowed?)
I think you can easily do the basics in QTKit ... except the speed-
control part. There are CoreAudio AudioUnits that will do speed/pitch
control, but I don't know how you'd splice those into a QTKit-based app.
It's been a few years since I used QTKit, though, so I may have
forgotten something, or they may have added more functionality in 10.5.
