Examples
Use cascade~ with filtergraph~ in multi-filter mode to efficiently process a complex parametric filter
Cascaded series of biquad filters
| list | filter-coefficients (sets of five-per-biquad) [list] |
In right inlet: The filter coefficients can be provided as a in the left 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. |
| clear | Resets all coefficients and sample-memory to 0. | |
| bypass | operational-flag (0 or nonzero) [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. |
| 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 | operational-flag (0 or nonzero) [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). |
