MDCTInv_G7291

Computes inverse MDCT.

Syntax

IppStatus ippsMDCTInv_G7291_16s(const Ipp16s pMDCTCoeffs[160], Ipp16s pSrcDstMDCTPrevCoeffs[160], Ipp16s pDst[160], Ipp16s scaleFactor);

Parameters

pMDCTCoeffs	Pointer to the MDCT coefficients.
pSrcDstMDCTPrevCoeffs	Pointer to the old input/output MDCT memory.
pDst	Pointer to the output signal.
scaleFactor	Scale factor for the normalization MDCT coefficients.

Description

The function ippsMDCTInv_G7291 are declared in the ippsc.h file. The function computes inverse MDCT using given normalization factor. See [ITU7291] section 7.3.8.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when any of the input or output pointers is NULL.
ippStsRangeErr	Indicates an error when scaleFactor is less than 0.
