Re: [linux-audio-dev] Amplitude (de)modulation with JACK (was "with LADSPA")

Lars, thanks, I'll try.

!! Well, it seems like "to be inside LADSPA" is unneeded restriction.
Any JACK-enabled apps will be helpful. My mistake, sorry... The thread
subject was changed.

The "Sine oscillator" in the LADSPA toolkit (1046/sine_fcaa)

The "Sine oscillator" in the LADSPA toolkit (1047/sine_fcac)

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?
