demodulating audio cassette wav files

Chuck: You may want to look at Jim Battle's SOL emulator project (http://www.thebattles.net) for inspiration. I haven't looked at the code recently, but IIRC it has a software-based method for demodulating WAV files.

I have some cassette tape audio files using 300 baud 8/n/1 format simple fsk 1200/2400Hz I think. Same audio you would find on a cassette tape for program storage except in a wav file. Any easy way to demodulate it back into data? Something like a software (mo)dem that can read the audio file and create the contents? Otherwise I will have to type the program in again (yuck) or read it into the old machine and rig up a serial interface to transfer it to a new PC running a simulator (more fun but would rather just extract it directly).
