SynthesisDownFilterFree_SBR

Closes downsample synthesis SBR specification structure for real and complex signals.

Syntax

IppStatus ippsSynthesisDownFilterFree_SBRHQ_32sc32s(IppsFilterSpec_SBR_C_32sc* pFilterSpec);

IppStatus ippsSynthesisDownFilterFree_SBRLP_32s(IppsFilterSpec_SBR_R_32s* pFilterSpec);

Parameters

pFilterSpec

Pointer to the downsample synthesis SBR specification structure.

Description

These functions are declared in the ippac.h file. The functions close the downsample synthesis SBR specification structure pFilterSpec by freeing all memory associated with the specification created by ippsSynthesisDownFilterInitAlloc_SBR. Call ippsSynthesisDownFilterFree after the transform is completed.

The ippsSynthesisDownFilterFree_SBRHQ_32sc32s function closes the complex SBR specification structure.

The ippsSynthesisDownFilterInitAlloc_SBRLP_32s function closes the real SBR specification structure.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when the pFilterSpec pointer is NULL.

ippStsContextMatchErr

Indicates an error when the specification identifier pFilterSpec is incorrect.
