I have a Windows Forms application, and I use an instance of Windows Media Player (via WMPLib) to play some audio/video files, either wmv or wav format. What I currently need to do is split the original file and "extract" one ore more clips from it, let's say 3-4 seconds from a specific point in time of the file.

Any ideas how to do this?

Third party libraries are ok, as long as they are not all that expensive
第三方库是可以的,只要它们不是那么昂贵

Have a look at the Windows Media Encoder SDK. Something like this:
看看Windows Media Encoder SDK。像这样的东西:
Int32 StartTime = 60 * 1000;Int32 EndTime = 120 * 1000;String SourceName = "original.mp3";String DestinationName = "split.mp3";WMEncBasicEdit SplitFile = new WMEncBasicEdit();SplitFile.MediaFile = SourceName;SplitFile.OutputFile = DestinationName;SplitFile.MarkIn = StartTime;SplitFile.MarkOut = EndTime;SplitFile.Start();should work.
