First you need to have the following software installed:
- Firefox 2.0 or above (because you need to install some Firefox plugin)
http://www.mozilla.com/en-US/firefox/upgrade.html - Firefox plugin Video DownloadHelper
https://addons.mozilla.org/en-US/firefox/addon/3006 - FLV Extract (open source tool to extract audio from flv file)
http://moitah.net/
- Install Firefox
- In Firefox, Go to the Video DownloadHelper site and install the Video DownloadHelpler plug in, or you can select menu [Tools][Add-ons], click "Get Add-ons" and search "Video DownloadHelper". (Oh, and while you are there, search "Adblock PLus" for blocking all advertisement and "No Script" to stop JavaSCript from running by default. They make your web surfing life much safer)
- For FLV Extract, just expand the file and run the FLVExtract.exe
Finally here's the step of how to do it. Let's say you love the webcast 2KShow that me and my friend Mr.K do so much that you want to extract the audio (feel free :-D). Here's the steps:
- Using Firefox, go to the YouTube page, like http://www.youtube.com/watch?v=muNOOeWfjYQ
- On the toolbar, you can see the Video Downloader icon rotating. Click on the icon, and in the dropdown, select the file you want to download. Same video many have multiple version, just pick one. You should see the file being downloaded as ".flv" format, which is Adobe Flash video format.
- Open FLVExtract.exe. On the window, UNCHECK "Video" and "TimeCodes". You should be only "Audio" being checked.
- Drag and Drop the .flv file on "FLV Extract", and an mp3 file will be created with the same name and the same folder as the original .flv file.
- DONE. Enjoy the mp3 audio file.
By the way, if case some haters wanted to accuse me for "stealing music" or crap like that, here's the list of legitimate reason why some of my friends do this all the time:
- We have a Sunday worship team and we try to practice contemporary worship music close to the arrangement of the original performance. So we use YouTube to find the songs, extract the low quality audio out, put them in iPod so that we can get the groove down. After the Sunday service, we delete those files. They are low quality enough to not give us ultra enjoyment, but good enough for us to learn the arrangeemnt. In fact, I borught a few songs from iTune after finding the songs appealing.
- My Chinese dance friends use music from the Chinese dance clip on YouTube to practice dance.
