声道

Then you will see the receiver is not the Normal bright light, this means that in the L channel and R-channel analog interface is no analog audio output of.

这时你会看到接收机的 Normal 指示灯是不亮的，这表示在 L 声道与 R 声道模拟接口上是没有模拟音频输出的。

It combines the stereo signal into a monaural downmix signal and extracts the parameters of stereo signal as the stereo image.

PS的压缩概念来自於将双声道讯号合成为单一声道讯号，再加上由左右声道所抽取出的双声道特徵来进行压缩。

The widely used circuit in Figure 1 performs this function by dividing the monaural signal between the two stereo channels and varying each channel's gain between zero and M such that at R7's centered position, each channel's gain is 0.707M.

图1中广泛使用的电路完成这样的功能。通过区分两个立体声声道之间的单声道信号和在0和M之间改变每个声道的增益，例如在R7的中心位置，每个声道的增益为0.707M。

For the design of PS tool, the thesis will focus on the T/F stereo parameter extraction which controls the delivery of stereo parameters both in time domain and frequency domain, and downmix method for generating the monaural downmix signal.

对於PS压缩的设计，本篇论文会著重在参数抽取和声道合成上。参数抽取控制参数在时间与频率上的解析度，以达到合适的特徵更新，而声道合成部份将讨论单一声道讯号的产生办法。

Audio engineers refer to a panoramic-potentiometer circuit as a circuit that generates left and right signals of correct amplitudes from a monaural signal and places the signal's image anywhere in a stereo-sound field.

通过区分两个立体声声道之间的单声道信号和在0和M之间改变每个声道的增益，例如在R7的中心位置，每个声道的增益为0.707M。

Relating to a system of transmitting, recording, or reproducing sound in which one or more sources are connected to a single channel; monophonic.

单声道的在播送、录音或制作声音系统中一个或多个信号源与一个声道相接的；单声道的

The left and right channels are combined to one digital data string via a multiplexor.

通过多路转换器将左右声道合成一个声道。

Therefore, this discovery denied the traditional distrust that "the reason why the myna can learn to speak is that the length of its vocal cords is nearly the same as that of human——that is 11 cm".

因而，这就否定了过去人们所怀疑的"八哥会学人说话是因为它的声道长度与人的声道长度基本相似——即约11厘米"这种论断。
