Install NAudio from Nuget:
PM> Install-Package NAudio
Add using NAudio.Wave;
and use this code:
void Main()
{
var mp3Path = @"C:UsersRonnieDesktoppodcastshanselminutes_0350.mp3";
var outputPath = Path.ChangeExtension(mp3Path,".trimmed.mp3");
TrimMp3(mp3Path, outputPath, TimeSpan.FromMinutes(2), TimeSpan.FromMinutes(2.5));
}
void TrimMp3(string inputPath, string outputPath, TimeSpan? begin, TimeSpan? end)
{
if (begin.HasValue && end.HasValue && begin > end)
throw new ArgumentOutOfRangeException("end", "end should be greater than begin");
using (var reader = new Mp3FileReader(inputPath))
using (var writer = File.Create(outputPath))
{
Mp3Frame frame;
while ((frame = reader.ReadNextFrame()) != null)
if (reader.CurrentTime >= begin || !begin.HasValue)
{
if (reader.CurrentTime <= end || !end.HasValue)
writer.Write(frame.RawData,0,frame.RawData.Length);
else break;
}
}
}
Happy trails.
