音频信号恢复

[肖笑]

各位，大家好

我是想将已经采集存储号的其他格式（非wav格式）文件恢复成可以直接播放的wav格式音频文件，请问怎么实现？

其实就是想将音频文件采集的过秤逆序执行。

补充一下：还有就是如何实现声音混合在一起的区分，比如，有大人的笑声和孩子的笑声以及噪声，这三种声音如何区分出来呢？是根据频率不同吗？他们的范围都是一样的啊，并且很可能有频率相同的时候呢，该怎么做呢？

比较着急，谢谢大家

Hi,

First all all, I believe that 音频信号恢复 is not as simple as anyone could describe how it is done here.

Secondly, may I suggest that some Research is done, be it online or with expertise(s) in that area.

And, finally, you, most likely, need the Sound and Vibration tools as well...
