推荐答案

我写了 我的硕士论文关于音频指纹.论文列出了一些开源解决方案来比较音乐听起来像什么的问题，并提供了它们之间的性能比较.可能有点矫枉过正，但那里有一些非常不错的应用程序.

I wrote my master's thesis on audio fingerprinting. The thesis lists a few open source solutions to the problem of comparing what the music sounds like, and provides performance comparisons between them. Might be overkill, but there are some really decent applications out there.

如果您只想通过标记数据进行比较，则要查看的标准是 ID3.基本上有两个版本，第一个非常简单(ID3v1)，由一个 MP3 末尾的 128 字节块组成.ID3v2 在 MP3 的开头放置了一个更大的、可变大小的块.

If you only want to compare by tagged data, the standard to look into is ID3. There are basically two versions, the first is very simple (ID3v1) and consists of a 128 byte block at the end of an MP3. ID3v2 puts a larger, variable sized block at the beginning of the MP3.
