Mac Fourier

Mac Fourier is open-source Macintosh software that allows you to record a sound through the microphone, and see a graph of its spectrum as a function of frequency. It's a Classic application, so you can run it on MacOS 9. It doesn't seem to work quite right in MacOS X in Classic mode (the recording controls act funny, and more importantly, the Analyze button doesn't work!).

• executable, source code, and resource files, in binhex format
  
• source code only, in Unix .tar.gz format (not sufficient to build the program, because you need the resource files as well)

This was compiled using the old CodeWarrior compiler, and would probably require some work to compile from source using gcc on a modern MacOS X system.
