list

Arguments

filter-coefficients [list]
The filter coefficients can be provided as a list in the left or right inlet. The coefficients should be in sets of five, each set corresponding to a second-order section or biquad. The first five coefficients in the list are used for the first second-order section in the series, the next five for the second, and so on.

bypass

Arguments

operational-flag [int]
The word bypass followed by a nonzero number will turn bypass mode on and cause the dry unfiltered signal to pass through to the object's outlet; followed by a 0 will output the filtered signal.

clear

Resets all coefficients and sample-memory to 0.

dictionary

Arguments

dictionary-name [symbol]
The word dictionary, followed by a symbol that references a named filterdesign object dictionary (set via the name attribute), will cause the cascade~ object to use the dictionary values for filter coefficients.

signal

In left inlet: Signal to be filtered. The signal is filtered by a series of two-pole two-zero (i.e. biquad) filters, often referred to as "second order sections".

zero

Arguments

operational-flag [int]
The word zero followed by a nonzero number will cause the filtered signal to be muted; followed by a 0 will output the filtered signal (this will not prevent the unfiltered signal from appearing at the outlet when bypass mode is turned on).
