There is a better option, that would be the BASS Library. http://un4seen.com/bass.htmlit has a dedicated forum and does DSP like fade/compressor/EQ, etc. Plus you can read a bunch of different audio formats. It has C# and vb.net support.
有一个更好的选择，那就是 BASS 库。http://un4seen.com/bass.html它有一个专门的论坛，可以做 DSP 之类的淡入淡出/压缩器/均衡器等。另外，您可以阅读大量不同的音频格式。它有 C# 和 vb.net 支持。

You could try NAudio- There would be a bit of programming required to do this but basically it would be along the lines of using NAudio to decode the MP3 first. Then passing the wave file to fade in (turn up the volume) at the time required and fade out (turn down the volume) when required. If your going to pass this to a client in a format other than wave you would then need to re-encode this file.
您可以尝试NAudio- 这样做需要一些编程，但基本上它会沿着使用 NAudio 首先解码 MP3 的路线。然后传递波形文件以在需要时淡入（调高音量）并在需要时淡出（调低音量）。如果您要以 wave 以外的格式将其传递给客户端，则您需要重新编码此文件。
