I have a decent pre-Alpha version of my audio analysis software running. It displays a real-time FFT plot from any supported audio input source. Pre-Alpha in this case means non-feature complete, but fairly solid, crash and leak free. The pic shows data being displayed on a labelled plot with the settings window up and displaying the current settings. Through the magic of Cocoa, changes to the sliders adjust the plot in real-time allowing easy setup for different sound sources. I have kinda written this software before, but in assembler on a Commodore Amiga. Luckily the Mac OS comes with a built in vector processing lib and though my G4 is hardly a Cray, it does a pretty good job from Objective-C using threads to bury the sound capture, and regular old events to perform data analysis and screen plotting. Any enquiries about this software can be directed to Highland Innovation Centre Limited in Scotland.
