SynthesisFilterInit_SBR

Initializes synthesis specification structure.

Syntax

Case 1: Operation on float-point signal.

IppStatus ippsSynthesisFilterInit_SBR_CToR_32fc32f(IppsFilterSpec_SBR_C_32fc** ppFilterSpec, Ipp8u* pMemSpec, Ipp8u* pInitBuf);

IppStatus ippsSynthesisFilterInit_SBR_CToR_32f(IppsFilterSpec_SBR_C_32f** ppFilterSpec, Ipp8u* pMemSpec, Ipp8u* pInitBuf);

IppStatus ippsSynthesisFilterInit_SBR_RToR_32f(IppsFilterSpec_SBR_R_32f** ppFilterSpec, Ipp8u* pMemSpec, Ipp8u* pInitBuf);

Case 2: Operation on fixed-point signal.

IppStatus ippsSynthesisFilterInit_SBRHQ_32sc32s(IppsFilterSpec_SBR_C_32sc* pFilterSpec);

IppStatus ippsSynthesisFilterInit_SBRLP_32s(IppsFilterSpec_SBR_R_32s* pFilterSpec);

Parameters

ppFilterSpec

Double pointer to the synthesis SBR specification structure.

pMemSpec

Pointer to the area for the synthesis SBR specification structure.

pInitBuf

Pointer to the initialization buffer.

Description

These functions are declared in the ippac.h file. The functions initialize the synthesis SBR structures:

ippsSynthesisFilterInit_SBR_CToR_32fc32finitializes the specification structure for ippsSynthesisFilter_SBR_CToR_32fc32f_D2L.

ippsSynthesisFilterInit_SBR_CToR_32f initializes the specification structure for ippsSynthesisFilter_SBR_CToR_32f_D2L.

ippsSynthesisFilterInit_SBR_RToR_32f initializes the specification structure for ippsSynthesisFilter_SBR_RToR_32f_D2L.

ippsSynthesisFilterInit_SBRHQ_32sc32s initializes the specification structure for ippsSynthesisFilter_SBRHQ_32sc32s.

ippsSynthesisFilterInit_SBRLP_32s initializes the specification structure for ippsSynthesisFilter_SBRLP_32s.

AAC decoder included into IPP Samples uses the functions ippsSynthesisFilterInit_SBR_RToC_32f and ippsSynthesisFilterInit_SBR_RToR_32f in the float-point version, and functions ippsSynthesisFilterInit_SBRHQ_32sc32s and ippsSynthesisFilterInit_SBRLP_32s in the fixed-point version. See introduction to this section.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when at least one of the specified pointers is NULL.
