Extract Audio Tracks From Viedos

This is a guide that explains how to extract audio tracks from any videos, not just YouTube.


First, lets download the ffmpeg tool (that’s for Windows Operating System. If you are using linux operating system, you can get the ffmpeg tool as a package distribution) and open the
 ffmpeg documentation in another window.

Lets choose a sample video which we will extract the audio track from. I found some music video clip “My Chemical Romance - Famous Last Words”


Now, lets download the music video.





If you are on a windows machine, you may use my VBScript program to download the video (download vbscript youtube video downloader, read how to use it here), or if you are on linux, you may use gawk program to download the video (download gawk youtube video downloader, read how to use it here).



After downloading the video, I ended up with a file named My_Chemical_Romance_-_Famous_Last_Words.flv.



Once you have downloaded the video, just for the sake of interest, lets find out the audio quality of this You Tube audio video.

The ffmpeg documentation does not tell us about a switch which would just output the audio parameters of the input file. After experimenting a little with the ffmpeg tool, it can be found that by just specifying ‘-i’ switch and the input video file, the ffmpeg will output input streams information and quit.
