摘要
人们对音频质量的要求正在不断地提高,从单声道到立体声,又在向多声道发展。然而,传输带宽和存储媒体容量却是有限的,需要用音频压缩编码方法对多通道数字音频进行处理。文中介绍了几种常用的多通道压缩音频编码方式的原理,并比较了它们的异同、压缩码率以及实际中的应用。
People's requirement of audio quality is rising,from monophony to stereophony,until mul-ti-channel surround sound.Due to the limitation of the transmission bandwidth and storage capacity,audio data should be compressed before transmitted.This paper introduces some kinds of audio coding method,gives the comparison among them,and shows their applications.
