可以将所有音频转换为mp3吗?
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents = false;
proc.StartInfo.FileName = @"""C:\ffmpeg\bin\ffmpeg.exe""";
proc.StartInfo.Arguments = "-i C:\\Matheus\\Matheus_Project\\Matheus_Project\\App_Data\\" + User.Identity.Name + "\\" + fileNameAndType + " -acodec libmp3lame -ab 128k C:\\Matheus\\Matheus_Project\\Matheus_Project\\App_Data\\" + User.Identity.Name + "\\" + fileName + ".mp3"; /* use /y to overwrite if there it exists already or will fail */
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = false;
proc.StartInfo.RedirectStandardOutput = true;
proc.StartInfo.RedirectStandardError = true;
proc.Start();
var output = proc.StandardOutput.ReadToEnd();
string output_error = proc.StandardError.ReadToEnd();
proc.WaitForExit();
proc.Close();
示例:
audio / x-m4a to mp3
audio / mp4 to mp3
audio / basic to mp3
audio / L24 to mp3
audio / mid to mp3
audio / x-aiff to mp3
audio / x-mpegurl to mp3
audio / vnd.rn-realaudio to mp3
audio / ogg to mp3
audio / vorbis to mp3
audio / vnd.wav to mp3
有什么想法吗?

public void ConvertWavToMp3(string filename) { 尝试 { string Flacfilename = AppDomain.CurrentDomain.BaseDirectory +“FlacRecording”;
ProcessStartInfo psi = new ProcessStartInfo();
psi.UseShellExecute = false;
psi.CreateNoWindow = true;
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.FileName = AppDomain.CurrentDomain.BaseDirectory + @"lame.exe";
psi.Arguments = "-b" + "128" + " --resample " + "22.05" + " -m j " +
"\"" + filename + "\"" + " " +
"\"" + Flacfilename + "\\" + Path.GetFileNameWithoutExtension(filename) + ".mp3" + "\"";
Process p = Process.Start(psi);
p.WaitForExit();
p.Close();
p.Dispose();
}
catch (Exception ae)
{
}
}
下载lame.exe并将其放入您的应用程序并使用wav文件名传递fullpath来调用abover函数。
