Detailed Description

template<size_t max_size, size_t max_block>
class daisysp::FIRFilterImplGeneric< max_size, max_block >

Generic FIR implementation is always available

Parameters

max_size	- maximal filter length
max_block	- maximal block size for ProcessBlock() if both parameters are 0 (via FIRFILTER_USER_MEMORY macro) Assumes the user will provide own memory buffers via SetIR() and SetStateBuffer() functions Otherwise statically allocates the necessary buffers itself

Member Function Documentation

Process()

template<size_t max_size, size_t max_block>

float daisysp::FIRFilterImplGeneric< max_size, max_block >::Process ( float in )

inline

Shift the state simulatenously (note: better solutions are available)

SetIR()

template<size_t max_size, size_t max_block>

bool daisysp::FIRFilterImplGeneric< max_size, max_block >::SetIR ( const float * ir, size_t len, bool reverse )

inline

Set filter coefficients (aka Impulse Response) Coefficients need to be in reversed order (tail-first) If internal storage is used, makes a local copy and allows reversing the impulse response
