This section describes the Intel IPP functions that can be used in implementing speech codecs following the GSM 06.10, 06.11, 06.12, 06.31, and 06.32 recommendations. The list of these functions is given in the table below.
Function Base Name | Operation |
---|---|
RPEQuantDecode_GSMFR | Performs APCM inverse quantization. |
Deemphasize_GSMFR | Performs de-emphasis filtering. |
ShortTermAnalysisFilter_GSMFR | Performs short-term analysis filtering. |
ShortTermSynthesisFilter_GSMFR | Performs short-term synthesis filtering. |
HighPassFilter_GSMFR | Filters input speech signal through a high-pass filter. |
Schur_GSMFR | Estimates the reflection coefficients by Schur recursion. |
WeightingFilter_GSMFR | Calculates the weighting filter. |
Preemphasize_GSMFR | Computes pre-emphasis of a speech signal. |
