推荐答案

"不是说您的问题所在，而是一些

You don''t say what your problem is, but some of these links[^] may be useful.

您必须更具体地讲，删除音频文件的一部分就像删除存储在其中的一些二进制数据，或将样本替换为零一样容易.

不能完全确定您要完成什么.

You have to be more specific with your problem, erasing part of an audio file can be as easy as deleting some of the binary data stored within, or replacing the samples with zeros.

Not completely sure what you''re trying to accomplish.

请记住，MP3文件是压缩音频.

您需要将文件(在内存中)解压缩为wav文件结构，处理实际的wav文件结构，然后将结果压缩为MP3.

这样会降低质量(这就是为什么音乐以WAV格式处理的原因)

您还需要一个mp3编解码器来解压缩，更重要的是再次压缩回音频.

使用jpeg图像时，这是相同的基本思想，您需要从jpeg中解压缩"图像，使用位图，然后再次压缩回jpeg.

祝你好运.

Remember that an MP3 file is compressed audio.

You need to decompress the file (in memory) to a wav file structure , work on the actual wav file structure and compress the result to MP3.

you will loose quality when doing this (that''s why music is handled in wav format)

You will also need a mp3 codec to decompress and more importantly compress back again the audio.

It''s the same general idea when working with jpeg images, you need to "decompress" the image from the jpeg, work with the bitmap and compress back again to jpeg.

good luck.
