I'm wondering if there are classes available for consistently
displaying audio
waveforms maybe as an extension to coreaudio ??
Ideally, i'd like something that would use peak files to display
waveform
data quickly supporting moderate zooming, i'm not writing an audio
editor, but
some detail is important in long passages.
if not, i guess i'll just roll my own waveform viewer.
There is currently no standard, however if you were to implement it, I
would do it as an Effect Audio unit. As one of it's properties, you'd
export the audio content (or some transform on it like an FFT). If you
feel like getting fancy, then add a view component that lets someone
see the audio as it passes through =).
And so begins the CoreAudio visual plugin architecture...
