comb1~ Abstraction comb filter
A comb filter creates equally spaced peaks or troughs in the output signal's frequency response at each multiple of the peak width (a frequency value in Hz). This is done by adding a slightly delayed version of a signal to itself, which causes regularly-spaced phase cancellation in the signalís spectrum. Negative values for the intensity parameter cause the center frequency of all peaks to be shifted by half the peak width (i.e. the troughs occur at each multiple of the given width). The comb1~ module is a basic FIR (finite impulse response) comb filter which is much simpler than MSPís standard comb~ object. Usually, more than one comb1~ will be needed to produce enough volume for any musically useful filtering effects (it has a potential gain of 2).The help file shows how its gain may be boosted by connecting three (or more) in series.
flange1~ Abstraction flanger
flange1~ is a simple flanger that is closely related to comb2~. The principal difference is that it uses a variable delay tap. An added parameter controls the portamento time of the resonant frequency when it is changed. This abstraction is intended for use with dynamic parameter changes. As with the comb filter, equally spaced peaks or troughs in the output signal's frequency response are created at each multiple of the peak width (a frequency value in Hz). This is done by adding a slightly delayed version of a signal to itself, which causes regularlyspaced phase cancellation in the signalís spectrum. Negative values for the intensity parameter cause the center frequency of all peaks to be shifted by half the peak width (i.e. the troughs occur at each multiple of the given width).
