A set of coefficients for use in an FIRFilter object. More...
#include <juce_FIRFilter.h>
Public Types | |
using | Ptr = ReferenceCountedObjectPtr< Coefficients > |
The Coefficients structure is ref-counted, so this is a handy type that can be used as a pointer to one. | |
![]() | |
using | Ptr = ReferenceCountedObjectPtr< ProcessorState > |
The ProcessorState structure is ref-counted, so this is a handy type that can be used as a pointer to one. | |
