and I will see if I can help you out!I’ve made this brilliant online tool to extract the audio from a downloaded Youtube(or other video) file.
All the rest of this post is obsolete now as I added the option to input a Youtube URL into the form but feel free to follow it for downloading only.
So how to actually download the file from youtube?
Well I suggest using this free Firefox browser plugin. Then simply navigate to the youtube video of your choice and click the little spinning balls in the bottom of your browser thus:
There may be more than one option for download but if it’s just for the soundtrack I’d suggest the .flv as this always works in the converter, other file types may work just as well it’s just that I’ve not tested for those. If you want the video and size is of no consequence I’d suggest getting one of the HQ/HD versions.
So get your video then upload it into my form above where my computer will perform black magic that strips the music/audio out and sends it back to you as an .mp3
Couldn’t make it easier than that could I? (Well if you ask nicely I’ll give you one you can use on your own linux machines for when mine’s is offline!)
