How do I programmatically extract the audio from a YouTube video? [closed]

I'm trying to create a C# application which allows me to extract just the audio from YouTube videos. I've come across sites that already do that, but I'm not sure how they actually work. What would be the best way to do this programmatically?

Thanks for any advice

If you prefer to download YouTube audio only, you can also do that online by visiting youtube-mp3.org. Copy and paste the URL of the YouTube video you'd like to convert to audio on the text section on the website. Once it's pasted, click Convert Video to start the process.

How do I pull just the audio from a video?

One of the quickest ways to extract the audio from a video file on a Windows PC is to use the VLC Media Player. Although VLC is a free media player app, it has some secret features, including conversion options built into it as well. You can use those conversion options to convert your video file into an audio file.

How can I extract background music from a YouTube video online?

To make edits to the audio right click on the video in the timeline and select Detach Audio. A new track will appear and you can click on it to select it. Now you can cut or trim the file and you can even add effects to it. When ready just click the Export button at the top right of the screen.

Writing an application for this might be overkill. Existing tools already do a pretty good job, and it's hard to beat their simplicity:

wget http://www.youtube.com/get_video.php?video_id=... |
  ffmpeg -i - audio.mp3

All done!

If your application needs to do something special with the audio afterwards, it would make sense to write an app for that part. But for just getting the audio out, shelling out to ffmpeg will be a lot easier.
