Description: 软件企业的人才需求软件工程师
喜欢为同事走查代码，并以此获得学习他人有点的机会；
懂得自己只是可能比业务专家更懂编程。
项目开始喜欢问:“那是什么？这是为什么？”。
-Personnel needs of software companies like software engineers to go check the code for colleagues, and thus get the chance to learn a little bit of others know they just know better than experts in programming business. Beginning of the project like to ask: " What is that? Why?."

Description: 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 logarithmic, but A-law was specifically designed to be simpler for a computer to process. The standard also defines a sequence of repeating code values which defines the power level of 0 dB.
The µ -law and A-law algorithms encode 14-bit and 13-bit signed linear PCM samples (respectively) to logarithmic 8-bit samples. Thus, the G.711 encoder will create a 64 kbit/s bitstream for a signal sampled at 8 kHz.[5]
G.711 μ-law tends to give more resolution to higher range signals while G.711 A-law provides more quantization levels at lower signal levels. When using μ-law G.711 in networks where suppression of the all 0 character signal is required, the character signal corresponding to negative input values between decision values numbers 127 and 128 should be 00000010 and the value at the decoder output is-
