自己编写的一款可以进行双路PCM语音混频的程序，针对的是16位的PCM语音数据，经过验证，比常规的混音算法质量好许多，特别是进行多路混频时，重复调用该程序也可以达到比较满意的结果。-own section can be prepared for two-way voice PCM mixing procedures, The address is 16 PCM voice data, after verification, than conventional mixing algorithm m

双向4路音频16路采样，时分复用组帧，光纤传输-Two-way 4-way 16-way audio sampling, time division multiplexing framing, optical fiber transmission

ITU 的G722.1编码器，包含Annex C，是当前复杂度最低的编码器，并且压缩质量非常好，适合高并发voip使用，实测单i5cpu可以支持3000路以上的实时并行处理，采样率16000和32000 码率16000-48000，以800为梯度。-The ITU G722.1 encoder, including Annex C, is currently the least complex of the encoder, and the compression quality is very
