PCM逐次比较法编码译码,CVSD编码译码-successive PCM decoding method coding, coding CVSD decoder

音频解码，PCM解码后可通过SPEEX解码，码流可达到2~6KB/S,Audio decoder, PCM decoded by Speex decoding, bit-stream can reach 2 ~ 6KB/S

G.711使用64Kbps的带宽，可将14bits转换成8bits。目前G.711有两个编码方式，A-law以及Mu-law。-G.711 defines two main compression algorithms, the µ -law algorithm (used in North America & Japan) and A-law algorithm (used in Europe and the rest of the world). Both are logarith
