lpass2~

lowpass filter


A second-order IIR lowpass filter which is similar to the standard MSP object lores~ (a resonant lowpass filter). Like lpass1~, the cutoff frequency in the second inlet defines the point at which the high frequencies will start to be attenuated. However, lpass2~ also takes a "damping factor", which controls the slope of the cutoff. Damping values greater than 1.41 produce a mild slope similar to that of lpass1~. However, damping factor values less than 1.41 produce moderate to extreme gain boost around the cutoff frequency, characterizing this filter as a resonant lowpass filter (the gain boost creates a mild to pronounced resonating effect).
