Don said:It shows the other signals, certainly. To call it frequency modulation
is nothing more than your chosen interpretation. There is no
justification for that interpretation.
What is your interpretation of a FFT, which shows a prominent nearly
narrow band sinusoid

and sounds like a loud noise?

The wave file contains 16384 points, which facilitates FFT analysis.
Short term spectra show the sinusoid rapidly hopping around 900 Hz. Any
insights you have would be appreciated.
