CyanPhase Notch This is a BETA filter, while it is quite stable, right now there might be some bugs. I would REALLY recommend to send me email of the ones you encounter. Sometimes the LFO will not work for odd reasons if so, please tell :) This is a Notch (band reject) filter, meaning it punches a "hole" in the frequency spectrum.
