Decodes quantized ISFs in case of DTX mode.
IppStatus ippsISFQuantDecodeDTX_AMRWB_16s(const Ipp16s* pSrcIdxs, Ipp16s* pDstQntIsf);
pSrcIdxs |
Pointer to the 5-element vector quantization indices. |
pDstQntIsf |
Pointer to the 16-element ISF vector in the frequency domain (0..0.5) . |
This function is declared in ippsc.h file. The function decodes quantized ISFs from the received codebook index in case of DTX mode.
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when one of the specified pointers is NULL. |
