I am presently using CoolEdit to generate modulated audio tones for test purposes. The only FM envelope that is possible to define is a sine, square or triangle.
Is anyone aware of a software signal generating application (Windows PC) that will allow me to FM a signal with a _complex_ or arbitrary waveform? This also implies a graphical interface of some kind for shaping the latter.
Both the carrier and modulating frequency should be created in software, ie. not sampled.
I need something that will output via the soundcard as save as WAV or MP3, not just a mathematical model.
Thank you,
Mark Waugh
