Technical Examples

A sound codec including a compression portion and a decompression portion. The compression portion separates the incoming sound packet bandwidth into frequency sub-bands using a bank of infinite impulse response (IIR) filters. In accordance with the invention, the lower frequency signals are divided into more sub-bands than the higher frequency signals. Once the signals are divided into sub-bands, each sub-band signal is quantized. The resulting signals of all of the quantized sub-bands are then sent out over a communications link along with the filter state at the end of each sound packet. The decompression portion recombines the individual sub-band signals together (using a bank of infinite impulse response (IIR) filters) to form the audio data using the filter states to configure the reconstruction.
