ImpulseResponseEnergy

Implements shape codebook vector convolution and energy calculation.

Syntax

IppStatus ippsImpulseResponseEnergy_G728_16s(const Ipp16s* pSrcImpResp, Ipp16s* pDstEnergy);

Parameters

pSrcImpResp	Pointer to the input impulse response vector [5] of the synthesis and weighted filter.
pDstEnergy	Pointer to the output energy vector [128] of the convolved shape codevector.

Description
