问题描述

头？柱状图？渠道？有没有人有这个问题的经验？

I like to be able to compare mp3’s programmatically. The problem I don’t know by what. Header? Histogram? channels? Does anyone have experience with this subject?

推荐答案

我写的我的硕士论文的音频指纹。本文列出了一些开放源代码解决方案比较一下音乐听起来像的问题，并提供了它们之间的性能比较。可能是矫枉过正，但也有一些真正像样的应用程序在那里。

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.

如果你只是想通过标签数据进行比较，寻找到这个标准是 ID3 。基本上有两个版本，第一个是非常简单（的ID3v1），由以MP3的最后一个128字节的。 ID3v2的把一个较大的，可变尺寸的块的MP3的开头。

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.
