This can create some interesting audio effects for music such as a wah-wah effect, or the scanning/sweeping filtering effect heard in some electronic music where the sound seems to hollow out as the resonant peak scans through the audio band.
Starting from a passive Bridged-T notch/band reject filter, this project uses an op amp to transform the filter into a bridged T peak filter, and using a potentiometer, the resonant peak can be moved within the audio range from below 100Hz to around 14.5 KHz.
This project includes an LTSpice simulation and a breadboard prototype with some audio examples.
