This filter can not be found in any other plugin on the market.
The algorithm is one of our own design and is not based on the standard biquad topology or any other standard FIR or IIR filter. is a true zero delay filter having no feedback leg. The algorithm is based on the differential equations governing the motion of air molecules. The frequency response is similar to the Massberg filter in that it completely throttles open at high frequencies without being pinned to the Nyquist, except that because the filter is not implemented using feedback there is no phase delay.
The time domain response of this filter is so fast that we actually inject a 16 sample smoothing function to soften any envelope edges applied to the filter's cutoff frequency. The smoothing function can be changed or disabled in the settings menu.
If your ears are sensitive to existing filters which inject a slight resonance into the audio, and you are looking for a fresh sound based on an absolutely clear and punchy frequency response, then this is your filter.
