I'm just taking a few tentative steps into OS X programming using
XCode, but have a couple of ideas for things I'd like to work on in
the future, and was just wondering if any of you more more
experienced programmers could maybe give me an idea if they could be
achieved relatively easily.
One of the things I'd really like to do is to create a plugin for
Quartz Composer that grabs an audio stream from a particular source,
and draws the volume levels for each frames-worth of the audio as
brightness values across a 1D image strip of a given length.
So, in very simplified pseudocode, it would:
* Work out the current frame-rate
* Grab one frames-worth of audio
* Create 1D image of set length
* Scale audio information to appropriate number of samples
* Write level information into image, with appropriate scaling
* Pass image to QC
I will post this also to the Quartz Composer Devlist, so apologies in
advance if some of you receive this twice.
