This directly violates the Youtube API terms of service. https://developers.google.com/youtube/terms

Under Prohibitions: "8. separate, isolate, or modify the audio or video components of any YouTube audiovisual content made available through the YouTube API;

9. promote separately the audio or video components of any YouTube audiovisual content made available through the YouTube API;

10. access any portion of any YouTube audiovisual content by any means other than use of a YouTube player or other video player expressly authorized by YouTube;

11. store copies of YouTube audiovisual content;"

I'm not using their API

Nice idea!

I'm not sure about the legal issue here though. If I see it correctly, you are downloading the songs to your server and serve the file from there. A lot of content that is uploaded is often times illegal, so you might be charged for distributing illegal content (illegal as in copyright).

What I'm also wondering. How come the parsing takes so long? I know other services that are a lot faster. Is it just the speed limit of the server itself?

First of all I'm sorry it takes so long. I actually used this for extracting the mp3 https://github.com/flagbug/YoutubeExtractor As for the legal issue, I'll take it down if they ask me to. I've seen other YouTube video extracting things which makes me think YouTube doesn't mind so much

WOW, thank you so much. There are lot of underground DJs on YouTube who upload their remixes and you can't find them anywhere else on the internet. Downloading the YouTube video and extracting the sound is the only way to preserve their work and listen to it offline.

This makes things so much easier. Thank you.

You may want to look into youtube-dl (http://rg3.github.io/youtube-dl/). This tool seems to limit the bitrate to 64kpbs, while youtube-dl lets you configure the audio quality.

I wrote a wrapper service around youtube-dl: https://github.com/bertique/node-yt-to-mp3

YouTube is a registered trademark of Google Inc.

I'm afraid, you could? run into legal issues by using the word "YouTube" in your domain name.

http://www.google.com/permissions/trademark/rules.html

I'm sure I've read something in the ICANN rules that says domains containing a trademark can be petitioned against (although that may only be for exact wording). If they can do it, Google aren't exercising the right to it as there are other domains that have been around longer.

Meta: The headline makes no sense to me at all. Perhaps "Shown HN: Replace youtube.com with soundyoutube.com for any video to get just the sound."

That does seem like it makes more sense. I was just trying to make it short. I don't know if I can change it now though.

Thanks, I saw the gifyoutube one and made this. I was reluctant to share though because I was afraid they'd shut it down.

Awesome! This is a great service; I've often wondered why YouTube doesn't offer this on its own?

Really, you have? How about because hours of music is illegally uploaded to their site every day?

Or just use youtube-dl.

Isnt it against TOC of Google?
