Hello Paul - 

CA>> The 'psycho accoustics' that LAME uses to generate MP3
CA>> sound files is really resonant frequency response. Two
CA>> identical frequencies will collide generating a third
CA>> resonant frequency that is usually perceived as a buzzing
CA>> insect sound similar to a mosquito. With 'tuning' etc. and
CA>> slight offsets of the two frequencies this resonant
CA>> frequency can be useful.

It's been about 40 years or more but yes, I do think it is
similar using feedback to attenuate the circuit to the required
frequency.
