Quantization Functions

This section describes functions that perform quantization specific to the AMRWB+ speech codec.

• ISFQuantDecode_AMRWBE
  Decodes quantized ISFs from the received codebook index.
• ISFQuantDecodeHighBand_AMRWBE
  Decodes quantized ISF of HF-band signal.
• ISFQuantHighBand_AMRWBE
  Performs ISF quantization of HF-band encoded signal.
• GainQuant_AMRWBE
  Quantizes the adaptive codebook gains.
• QuantTCX_AMRWBE
  Quantizes the pre-shaped spectrum in TCX mode.
• GainQuantTCX_AMRWBE
  Performs the gain optimization and quantization.
• GainDecodeTCX_AMRWBE
  Decodes the global TCX gain.
• EncodeMux_AMRWBE
  Encodes and multiplexes subvectors into several packets.
• DecodeDemux_AMRWBE
  Demultiplexes and decodes subvectors from several packets.
