freqgen turns your PC into a frequency generator under Windows 95/98/ME/NT/2000/XP. freqgen is a "command line program". The shortcuts are set up to run "freqgen -g -S". This allows people who don't know what "command line program" means to use freqgen with frequency data files that come with freqgen, and to generate squarewaves to the best of your soundcard's ability. freqgen uses your soundcard. The frequencies that are generated are output from your soundcard's "line out" jack. Your PC, with freqgen and the hardware to turn the signal from your soundcard into the right waveform/voltage, can be used either to drive a Bare/Rife device, or as a pad/contact frequency therapy device.
