EngineersFilter is a filter plugin that allows for extremely steep filtering. It achieves this by implementing high order IIR filter design methods that are commonly used in science and engineering, namely Butterworth, Chebychev, inverse Chebychev, elliptic (aka Cauer), Bessel and Papoulis filters.
Each of these filter design methods can be applied to create lowpass, highpass, bandpass, bandreject, high/low shelving and peak/dip filters of orders up to 20.
- ultra-steep filters possible
- design methods: Bessel, Butterworth, Chebychev I and II, elliptic, Papoulis
- characteristics: lowpass, highpass, bandpass, bandreject, low-/high shelf, peak
