c语言处理mp3文件大小,如何用C语言获取MP3的长度#

我的解决方案是

sox

声音处理库。

public static double GetAudioDuration(string soxPath, string audioPath)

{

double duration = 0;

var startInfo = new ProcessStartInfo(soxPath,

string.Format("\"{0}\" -n stat", audioPath));

startInfo.UseShellExecute = false;

startInfo.CreateNoWindow = true;

startInfo.RedirectStandardError = true;

startInfo.RedirectStandardOutput = true;

var process = Process.Start(startInfo);

process.WaitForExit();

string str;

using (var outputThread = process.StandardError)

str = outputThread.ReadToEnd();

if (string.IsNullOrEmpty(str))

using (var outputThread = process.StandardOutput)

str = outputThread.ReadToEnd();

try

{

string[] lines = str.Split(new string[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);

string lengthLine = lines.First(line => line.Contains("Length (seconds)"));

duration = double.Parse(lengthLine.Split(':')[1]);

}

catch (Exception ex)

{

}

return duration;

}
