LSFDecodeErased

Reconstructs quantized LSFs in case when a frame is erased.

Syntax

IppStatus ippsLSFDecodeErased_G729_16s (Ipp16s maIndex, Ipp16s* pQuantLSFTable, Ipp16s* pQuantLSF);

IppStatus ippsLSFDecodeErased_G729_32f (int maIndex, Ipp32f* pQuantLSFTable, const Ipp32f* pSrcPrevLSF);

Parameters

maIndex	Switched MA predictor (L0) .
pQuantLSFTable	Pointer to the input/output table [4][10] of 4 previously quantized LSFs vectors, in Q12 for 16s data.
pQuantLSF	Pointer to the quantized LSF output vector [10], in Q12 for 16s data.

Description

The function ippsLSFDecodeErased_G729 is declared in the ippsc.h file. This function retrieves the quantized LSF coefficients through the previously decoded switched MA-predictor index (L0).

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when one of the specified pointers is NULL.
ippStsOutOfRangeErr	Indicates an error when maIndex < 0, or maIndex ≥ MA_NP.
