| Abstract: | This paper introduces the implementation of a new compressed coding algorithm based on SSCPA(Sound Signals Charateristic Parameters Analysis)and quadratic curve simulative method.The algorithm uses short-time energy to divide sound signals waveform simply into two bands:non-sound band and sound band.This algorithm uses simple data-structure and has traits such as simple calculation lower lack-fidelity-rate,lower coding-rate,non-uniform velocity,less complexity in algorithm space and practicability. |
