CompressEnvelopTime

Performs an adaptive amplitude compression.

Syntax

IppStatus ippsCompressEnvelopTime_G7291_16s(const Ipp16s pSrcEnvelopTime[28], Ipp16s pSrcDst[160], Ipp16s pMem[2]);

Parameters

pSrcEnvelopTime	Pointer to the desired time envelope .
pSrcDst	Pointer to the shaped input/output signal.
pMem	Pointer to the input/output memory for 2 past time envelope parameters.

Description

The function ippsCompressEnvelopTime_G7291 is declared in the ippsc.h file. The function shapes the excitation signal in time domain and performs adaptive amplitude compression in order to attenuate large deviations from this envelope according to [ITU7291] section 7.2.5.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
