Would you technical guys agree that the two tone interaction
we are hypothesizing can be approximated to low order by:

l*sin((wh+wld*sin(wl*t))*t) + h*sin((wl+whd*sin(wh*t))*t)

with h and l related to the amplitudes of the HF and LF
components respectively, wh the frequency of the HF tone, wl
the frequency of the LF tone and wld and whd a measure of
the "depth" in Hz of the cross modulations that are related
to the relative strength of the two tones?

If so, I'd appreciate input on what might be a reasonable
set of parameters.
