Extract audio from VIDEO_TS VOB Files in Ubuntu

Last Updated on January 28, 2022

Extracting audio from a CD or DVD is quite a simple task, in Windows, at least. You just have to use the Windows Media Player’s media ripping function and everything will be automatically done for you. In Ubuntu, however, it takes a bit more steps. Nonetheless, the whole process is as simple as it is in Windows.

In this post, we will discuss the steps involved in extracting audio from VIDEO_TS VOB Files in Ubuntu.


Disclaimer: We do not condone piracy. Please check the laws regarding the ripping of digital media in your country. If it is illegal, don’t do it. Make sure that you own the media you are trying to RIP. We at errorfixer are not responsible for any legal repercussions.

Tools Required

The tools required us are listed below. Depending on your system, they may or may not be present in your Ubuntu installation. If already present, skip the steps mentioned here and directly go to the procedure.

  • ffmpeg
  • normalize
  • cdrecord

Installing ffmpeg

  • Type Alt + Ctrl + T to open the Terminal.
  • Type “sudo apt-get update && sudo apt-get upgrade” (without quotes). Enter your password and then hit the enter key.
  • Type “sudo add-apt-repository ppa:kirillshkrogalev/ffmpeg-next“(without quotes). Hit Enter.
  • Type “sudo apt-get install ffmpeg” (without quotes). Press enter.

Installing normalize

  • Type “sudo apt-get install normalize-audio lame mpg123” (without quotes). Press enter.

Installing cdrecord

  • Type “sudo add-apt-repository ppa:brandonsnider/cdrtools” (without quotes) in the terminal. Hit enter.
  • Type “sudo apt-get install cdrtools“. Hit enter.

Now all our tools are installed in the system, we can now proceed with ripping the DVD.

How to RIP CD/DVD in Ubuntu

  • Once the CD/DVD is mounted on your drives, take a note of its path.
  • Now in the terminal, type “ffmpeg -i /path/to/dvd/VIDEO_TS/file1.cob -c:a pcm_s16le -ar 44100 -ac 2 -f wav file1.wav“. Repeat this for all the files that you want to extract the audio from by replacing the file1.vob everytime.
  • Now we will normalize the audio from these files in order to make them clearly audible in your speakers. For this, type “normalize -, *.wav” (without quotes) in the terminal.

By following this procedure, you will be able to extract audio from files in a CD/DVD without any use of complicated tools or expertise. If this works for you, tell us about it in the comments section. In the case of any problem, let us know via the comments and we will help you out.
