acc是什么意思？acc文件怎么打开？acc格式是Advanced Audio Coding的缩写，ACC是是杜比实验室为音乐社区提供的技术，号称「最大能容纳48通道的音轨，采样率达96 KHz，并且在320Kbps的数据速率下能为5.1声道音乐节目提供相当于ITU-R广播的品质」。acc格式文件基于MPEG-2的音频编码技术，和MP3比起来，不仅音质较好，而且能节省30%的储存空间与带宽。它是遵循MPEG-2的规格所开发的技术。松下的mp3产品都采用了这种编码方式，当然也兼容mp3格式，我自己使用时发现aac是非常好用的音频格式，128kbps的aac足以和224kbps的mp3抗衡，空间却小了差不多一半，但是在空间上和结构上aac和mp3编码出来后的风格不太一样，喜欢与否属于仁者见仁智者见智的事情。acc格式属于mp4范畴。

AAC实际上是高级音频编码的缩写，目前只有苹果的硬盘式MP3支持这一种格式。AAC是由Fraunhofer IIS-A、杜比和AT&T共同开发的一种音频格式，它是MPEG-2规范的一部分。AAC所采用的运算法则与MP3的运算法则有所不同，AAC通过结合其他的功能来提高编码效率。AAC的音频算法在压缩能力上远远超过了以前的一些压缩算法（比如MP3等）。它还同时支持多达48个音轨、15个低频音轨、更多种采样率和比特率、多种语言的兼容能力、更高的解码效率。总之，AAC可以在比MP3文件缩小30%的前提下提供更好的音质。

我们可以使用activeplayer即可进行播放acc格式的音乐！iac/acc专用播放器|active player媒体播放器v3.8
