Abstract
The system and method of the present invention comprises an apparatus and method for ultra-low rate encoding of sound parameters. The method includes encoding a plurality of frames of pitch and gain information based on a predetermined quantizer table. After the pitch and gain frames are encoded, the frames are analyzed to determine which frames have the lowest distortion value. The frames with the lowest distortion value are subsequently transmitted.
Claims9
A method of ultra-low rate encoding of sound parameters, comprising
- a) receiving a plurality of frames of pitch and gain values;
- b) encoding said plurality of frames of said pitch values based on a calculated distortion value;
- and
- c) encoding said plurality of frames of said gain values based on a predetermined quantizer table.
