| # | Name | Type | Description |
|---|---|---|---|
| 1 | IIRState | TIirState |
Result: stored in self (calling object)
Remarks:
Free any memory associated with the IIR filter initialized with the IirInit routine. The method can be called more than once. Nothing will be freed, if the filter is not initialized, but IirState must be initialized either with zeros or a call to IirInit before passing it to this routine.
