cascade~
Description
Use the cascade~ to filter an input signal using a series of biquad filters.
Examples

Use cascade~ with filtergraph~ in multi-filter mode to efficiently process a complex parametric filter

list
Arguments
filter-coefficients
[list]
The filter coefficients can be provided as a
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 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
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 filterdesign object dictionary (set via the attribute), will cause the cascade~ object to use the dictionary values for filter coefficients.
, followed by a symbol that references a named 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
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). Output
signal
The filtered signal.
