ALC_G169

Performs the automatic level control.

Syntax

IppStatus ippsALC_G169_16s(const Ipp16s* pSrc, Ipp16s* pDst, int len, IppsALCState_G169_16s* pALCMem);

Parameters

pSrc	Pointer to the input vector.
pDst	Pointer to the output vector.
len	Length of the vectors.
pALCMem	Pointer to the ALC state strcture.

Description

The function ippsALC_G169 is declared in the ippsc.h file. The function perform noise automatic level control using predefined clipping limit and target level which can be changed by the functions ippsALCSetLevel_G169 and ippsALCSetGain_G169 respectively. The ALC state structure must be initialized using the function ippsALCInit_G169 beforehand. The length of input and output vectors must be multiple of 8.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsRangeErr	Indicates an error when len is less or equal 0, or is not multiple of 8.
