The aim is:

signal (say, in 1-10Hz range)
The "Sine oscillator" in the LADSPA toolkit (1047/sine_fcac)
- to pass this modulated signal through some device,
- to demodulate it, and, as a result,
- to get that 1-10Hz signal.
Not sure about this. Maybe use the "Frequency tracker" in swh-plugins
(1418/freqTracker) and subtract the known frequency of your high
frequency sine from the result?
