Here's what the first 44 bytes of a WAV file looks like.

这是 WAV 文件的前 44 个字节的样子。

" Love at first byte" is rarealthough there are examples.

“一见钟情”虽然有例子，但很少见。

Like, this is the first byte, second byte, third byte, and so forth.

比如，这是第一个字节，第二个字节，第三个字节，依此类推。

The length here is just convenience for the code, so that the code just needs to read the first four bytes.

这里的长度只是为了方便代码，让代码只需要读取前四个字节即可。
