音频信号矢量编码算法
Vector Coding Algorithm for Audio Signal
摘要
Abstract
Reducing the coding compression rate under the premise of guaranteeing a good decoding sound quality, thereby to reduce storage space of speech signal, in this paper, a audio signal encoding algorithm combining linear predictive en-coding, SOM neural network vector encoding and Huffman encoding algorithm was proposed. It was innovative to convert a list of sound signals into two column signals so that subsequent vector coding could be performed. The combination of pre-dictive coding and vector coding was realized. The sound signal codec experiment, was carried out by Matlab software pro-gramming. Experimental results showed that under the premise of guaranteeing the quality of voice, the bitrate of the en-coding method was less than the lowest 64kbps standard bitrate of MEPG-1 Layer3, and the algorithm was simple. The coding algorithm proposed in this paper would have high research value and good application prospect in audio signal com-pression coding.关键词
