Designing an Inverse Notch Filter?

[miguelairs]

Hi!

I'm a beginner with Teensy audio, and I want to design an inverse notch filter to amplify resonances over white/pink noise, similar to the one in the screenshot below.

So far, I have tried using the filter object from the Audio Design Tool, but the Q-value for the resonance function doesn't reach high enough for me to hear the resonant frequency.

Any suggestions for what I can do next? I'd appreciate any and all help!

Many thanks!

A biquad with setBandPass is clearly the way to go... Very high Q may cause stability issues though, but you should be able to get higher than 5...
