Overview:

Have you ever encountered the problems as the below:

Want to extract audio stream into MP3 files for easy listening on your portable devices; Interested in taking an .mkv file and extracting the 5.1 audio file (I'm guessing an ac3 file); Wish to extract the audio from an mkv file, the file doesn't play in QuickTime but plays in VLC.

If so, this article will help you get the audio track you want with just a few steps. I have a live performance that I would like to extract the audio separately from the .mkv file, so I can put it on my IPod. But I only have VLC and have no idea if that even does the job. MKV is one of the Matroska file extensions, and the Matroska Multimedia Container is an open standard free container format, a file format that can hold an unlimited number of video, audio, pictures, or subtitle tracks in one file.
