This very simple passive circuit provides a simple audio shaping function. It was described by Derek Bowers inElectronic Design in February, 2012.
At the center of its range, its response is flat across the audio spectrum.
Adjusted away from center in one direction, it boosts signals above 1 kHz while attenuating those below 1 kHz. Adjusted in the opposite direction, vice-versa.
