Detailed Description¶

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

Public Functions Documentation¶

function FIRFilterImplGeneric¶

inline daisysp::FIRFilterImplGeneric::FIRFilterImplGeneric ()

function Init¶

template<typename... Args>
inline auto daisysp::FIRFilterImplGeneric::Init (
    Args &&... args
)

function Process¶

inline float daisysp::FIRFilterImplGeneric::Process (
    float in
)

function ProcessBlock¶

inline void daisysp::FIRFilterImplGeneric::ProcessBlock (
    const  float * pSrc,
    float * pDst,
    size_t block
)

function Reset¶

inline void daisysp::FIRFilterImplGeneric::Reset ()

function SetIR¶

inline bool daisysp::FIRFilterImplGeneric::SetIR (
    const  float * ir,
    size_t len,
    bool reverse
)

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

Public Static Functions Documentation¶

function GetLatency¶

static inline constexpr  size_t daisysp::FIRFilterImplGeneric::GetLatency ()

Protected Attributes Documentation¶

variable size_¶
