Raw audio from youtube ?

Although I donot know how to extract a raw mp3 from youtube exactly.
I download it here ( http://mp3fiber.com/ ) with 320kbps which is enough to me.

JDownloader works for this (and much more)
I don't know if you'll get a better audio that if you download with something else, but you could donload the video and then rip the audio with another software

Anyway, why do you download from youtube ? Unless if it's something else that music that exists on records, there's not much point

Most YouTube downloaders give you 128kbps audio even if you download the HD file (you can check that in file properties). I was looking into that too cause I like good audio. The only software that gives you 253kbps (you won't get anything better) is ChrisPC Free VideoTube Downloader. It's really great. But during installation make sure to click "decline" when it will ask about installing additional software called "RelevantKnowledge". It's a piece of shit that spreads all over your PC, not really harmful I think but annoying as hell and very hard to delete.

But if you want pure audio with no video then this software is not for you I guess.

Thanks for your answers guys. Actually I'm pretty nerd and was using KMPlayer for my tests. The audio is indeed flatened and lowered with all effects disabled and sound to 100%. But testing a file in VLC give me the feel that the audio is the same as when played from the youtube player !

I already tried mp3fiber, and even used it some days ago. Forgot about it, but it gives fine audio. I'm using an addon for firefox for youtube downloads (videos or sound alone) that's called "YouTube Video and Audio Downloader", the name's pretty generic but it's pretty useful and unintrusive, so try it out if you're interrested in tht kind of features.

TempeteJoachim : that's for something else than music indeed

There are a bunch of add-ons for Firefox (and Chrome, I guess) that would directly save the audio of a video for you in the same quality it's presented by YouTube. Alternatively, you can use online services like http://www.youtube-mp3.org/.
