NAudio 拆分 mp3 文件 [英] NAudio to split mp3 file

问题描述

我对音频或 mp3 的东西很陌生，正在寻找一种方法来在 C#、asp.net 中分割 mp3 文件.在没有太多帮助的情况下在谷歌上搜索了 3 天之后，我希望这里有人可以为我指明正确的方向.

I am very new to audio or mp3 stuff, was looking for a way to have a feature to split an mp3 file in C#, asp.net. After googling for a good 3-day without much of a great help, I am hoping that somebody here can point me to a right direction.

我可以使用 NAudio 来完成此任务吗?是否有任何示例代码?提前致谢.

Can I use NAudio to accomplish this? Is there any sample code for that? Thanks in advance.

推荐答案

我在 c# 中拆分 mp3 文件的最终解决方案是使用 NAudio.这是一个示例脚本，希望它可以帮助社区中的某些人:

My final solution to split mp3 file in c# is to use NAudio. Here is a sample script for that, hope it helps someone in the community:

string strMP3Folder = "<YOUR FOLDER PATH>";
string strMP3SourceFilename = "<YOUR SOURCE MP3 FILENAMe>";
string strMP3OutputFilename = "<YOUR OUTPUT MP3 FILENAME>";

using (Mp3FileReader reader = new Mp3FileReader(strMP3Folder + strMP3SourceFilename))
{
    int count = 1;
    Mp3Frame mp3Frame = reader.ReadNextFrame();
    System.IO.FileStream _fs = new System.IO.FileStream(strMP3Folder + strMP3OutputFilename, System.IO.FileMode.Create, System.IO.FileAccess.Write);

    while (mp3Frame != null)
    {
        if (count > 500) //retrieve a sample of 500 frames
            return;

        _fs.Write(mp3Frame.RawData, 0, mp3Frame.RawData.Length);
        count = count + 1;
        mp3Frame = reader.ReadNextFrame();
     }

     _fs.Close();
}

感谢 Mark Heath 对此的建议.
