一直很感谢老师的奉献，今天看到一款有趣的扒带软件，请教一下其用法可行性。

我在知乎上看到一个有趣的帖子，讲的是关于：
有没有可能把一首歌曲的人声和伴奏分离？它的原理是什么？主要用到什么技术？
——
好奇点了进去，看到了里面有人回答一款有趣的软件：Hit'n'Mix Play
据答主说，可以实现——
引用原话：
【可以把一首音乐的所有元素都分离出来，注意是所！有！元！素！是的，跟原始工程文件一样，鼓一轨，琴一轨，人声一轨，除了包络线这种没办法还原的，其他全部拆的干干净净，还能像autotune一样任意变调。记得当年刚发现的时候群里有人感叹以后工程文件就再也没有秘密了，扒带做伴奏乐的要失业了】。
如下图

我没有用过这款软件，想来请教一下晨风大大，这款软件您看着……实际可行性怎么样呢？
在这里给出知乎的地址，您可以去看看。

希望您能在百忙之中抽空回答一下这个问题，我对此感激不尽。

作为专业的音频制作人，我可以负责的告诉你，这是不现实的。
你听到的歌曲是把若干的分轨通过一系列的后期手段合成为一个波形的。
这种混合输出是破坏性的，不可逆的。
音频分为若干个频段，每个频段的加减会影响整体的效果。
无论是人声还是伴奏，其实只是整个音频的某些频段而已。如果你要把波形的频段分离开，是不现实的。因为当你去掉了这个波段，与其重合的其他声音也会被去掉。也就是说，人声和伴奏相重合的波段也会被去掉。

所以，无论是从歌曲中去掉人声或者从歌曲去掉伴奏都是不现实的。即使勉强去掉，效果也是差之又差的。

国外对这软件的评语非常差，有些网友甚至建议不要安装，因为装了之后没法卸载：

Pros
it was cool when it came out and being able to manipulate tracks and sampling for music production. But it

Cons
1.They use securom which they do not mention at all on their website or anywhere. I paid $99 for this 3 years ago, and regret doing it. I contacted them to complain, but they basically said 'suck it'.
2. Havent updated at all in 3 years and is not user friendly.

Summary
Do not touch with a barge pole.

"Do not install this preogram!!!!" April 20, 2013  |  By markkruse  |  Version: Hit'n'Mix Play 1.5.7
Pros
There is no Pro for this program!

Cons
At first it promises that you can mix without limitations - NOT SO!!!! It pops up only payed version! Also it cant deinstall which is a major setback for most systems, it will just be a crap program laying on the HDD using space and processor! DO NOT INSTALL!!! I suspect it to be malicious too, but not sure about that!

Summary
If you need to slow down system, and have useless files laying around go ahead install, otherwise do NOT install this! It makes false promises, and cant deinstall!

"Useless Program" March 09, 2011  |  By dreamlander  |  Version: Hit'n'Mix Play 1.5.7
Pros
No way to know for sure but it gives the impression of having isolated all the elements to a song.

Cons
Does not proove its claims. There is no way to remove the identified elements from the rip supposedly without a paid upgrade. Without removal, all this program does is play sounds.

Summary
It appears this COULD be an incredibly useful program second to none. One will never know until rolling the dice and upgrading to a paid version. Considering that this was uploaded and designated as a "FREE" program, the risk is high because already there is evidence of deception. So if the program has already been misrepresented as being free how can I trust that it will do what the developer says it will do? Moreover, there is no way to adequately evaluate the program since all the features claimed are blocked from being used without a paid upgrade. Given that it claims to do what no other program has been able to do, that it has not proven that it can, and lies about being free I do not think its wise to waste time on this.
