Well, using QuickTime you could make use of this component.
It does all that.

I'm just starting a project along the lines of an audio editor that
will be
displaying lots of audio waveforms, user-drawn envelopes, frequency
spectra,
and so on. The central thrust of the project involves the concept of
"overlays" - both visual and auditory - on sections of the sound
file. So my
waveform displays have to show semi-transparent layers and so on.
My question is - what would be the best technology to accomplish this?
Quartz 2D, an NSView subclass, or something else?
I am familiar with subclassing NSViews for drawing but I find them
pretty
inflexible for transparency layers, adding and removing layers, and
so on.
Quartz 2D seems like it would be better suited, but I've never used it
before. Would Quartz Composer be useful for this, or is that more for
constantly-moving stuff like screen savers, music visualization, etc.?
Any other suggestions?
