Figure 3From: Multiresolution Source/Filter Model for Low Bitrate Coding of Spot Microphone SignalsOverall quantization scheme, for each frequency band. Each LSF vector is mean normalized and decorrelated, using parameters of the GMM class that the vector was classified to. Decorrelation is followed by nonuniform quantization of the vector components, and this procedure is inverted to obtain the quantized LSF vector.Back to article page
