Ubuntu: How to Extract Audio From YouTube Video

Often, you have heard a rare nice song from a particular YouTube video and you wish you could just save that song (without the video) into your hard disk. Well, in Ubuntu, you can use UTube Ripper to extract audio from YouTube video and save it as mp3 file.

UTube Ripper is an application that works exclusively on Linux. It’s useful to download and convert YouTube videos in a simple and efficient way. While there are many online sites that can take the YouTube url, extract the audio and let you download the mp3 file, it gives you little room for customization. UTube Ripper provides more choices and allows you to set the conversion sample rate and bit rate. It can also convert the flv file to MPEG or avi video format.

Install UTube Ripper

Download the UTube Ripper deb file to your desktop.

Double click the file to start installation. This will fetch and install all its dependencies.

Once installed, go to Applications -> Internet -> Utube ripper.

Now, on http://www.youtube.com, find your favorite video and the song that you want to extract. Copy the exact url and paste it to the text field in the ‘Utube Video URL’ section

. Press ‘Download’ to start download the flv file to your computer. The downloaded file will be saved as video.flv under the /home/yourusername/.utube folder.

To extract mp3, check ‘Rip audio only‘ under the ‘Convert FLV’ section. Click ‘Browse’, navigate to the /.utube folder and select the file video.flv. Click ‘Convert’ to start the conversion. The mp3 file will be saved as audio.mp3. Rename the mp3 file and move it to other folder (else it will be overwritten in the next conversion).

To adjust the sampling rate and bit rate, click on the ‘Setting’ . You can customize the video output type, audio output type, audio sample rate, audio bit rate, video bit rate, video screen resolution.
