A user suggested I add audio analysis to the movie player plugin. Turns out Apple has some pretty easy APIs to add FFT analysis to your QT movie playback code, so I implemented it tonight. Its a bit rough, but this is nice because it grabs only audio from the currently playing movie (meaning you could, in theory have 2 of these going and get different FFTs out), and runs based off of volume in the patch, so you can fade out your audio and the FFT respects that. Kind of neat!

Wow. thats incredible. Does it work well with SnowLeo?

Yeah, it does, if you launch QC s a 32 bit app. Quartz Composer is a 64 bit app in 10.6, which complicated QT development since you cannot link against the lower level Quicktime 7 framework in 64 bit bundles or apps, which means you just loose a lot of things.

On top of it, some outstanding bugs in QTKit X mean that things that SHOULD work do not, so, Snow Leopard works, if you just run QC as a 32 bit app, everything is hunky dory. Same on 10.5 :) Stay tuned.
