Hi Steve,
Thanks for the tone generators.
Could you please help with finding a solution to the following problem?
I am quite lost in my search for a software that could FM modulate a voice from a
microphone (or even better a prerecorded voice) with a high frequency sinusoid carrier signal. The
frequency of the carrier signal supposed to be adjustable up to 20kHz.
I have found a code that supposed to do this here https://forum.audacityteam.org/t/modulate-one-waveform-track-with-another-fm-synthesis/19806/1
The first 42 seconds of the output wave looks good, but the sin wave starts deteriorating at 43.69020 and it gets even worse at 1:27.38060.
The code also uses a low pass filter, and I am not sure whether it will do any good for my purpose. The best would be a simple FM modulator code, which would allow the setting of the modulation parameters (to make it universal and tweakable).
Can you please advise if such software exists already, or how to write a Nyquist code that could accomplish this task.
Thanks for your help.
Joe
