    I always just download the youtube video as an MP4, and then I open it in Garage Band and delete the video track and export the audio track to iTunes. Works perfectly for me. :)

    I use www.keepvid.com and it gives you the option to download the video as an MP4.

    If you want decent quality, the video should be downloaded straight from YouTube (note *no re-ecnoded*, use a tool like jDownloader for this), then demux the resultant mp4 to acquire the aac file inside. This eliminates a whole generation of loss, which is desperately need.

    All this does is rip the audio from the video, there's no conversion and therefor loss of quality from the original YouTube video.

    Hey, if you just want the audio from the youtube video, you can use some youtube converter to help you. The one I used can help me extract audio from youtube videos online with high quality, and you can also use it to help you get audio from downloaded youtube videos on your computer. I got many music in this way.:D

    Another option, although sometimes it might take a bit longer, is to record the streaming audio in realtime using Soundflower.

    http://cycling74.com/products/soundflower/

    Once you have Soundflower installed, open your DAW (Garageband, Ableton, Logic, whatever) and choose Soundflower as your input audio device.

    In System Preferences, choose Soundflower as your output device.

    Now arm a stereo track in your DAW, then press play on the YouTube video.
    You should see and hear the audio streaming directly into your channel in the DAW. Now just record that audio, and edit however you need. This gives you a clean recording with no added compression.

    This works for any audio in your browser, or any system sounds, you can record any audio the system is playing, YouTube videos, anything in the browser, etc.

    I have read this and other posts and I am still a bit confused. I need to extract audio only from a few clips to then edit in garageband. I believe I want to use .wav since the application I am going to eventually use them in works with wav best. There were many suggestions here, but I was hoping someone could give me one or two for my use.

    THANKS!

    This is absolutely the easiest way to save music from YouTube however the quality is -not- the best. Be the for a quick copy, this is the way to go.

    There are two ways to get the audio from a Youtube video. The first one is to download the youtube video as an MP4, and then I open it in Garage Band and delete the video track and export the audio track. The second one is to download the youtube videos and then convert the YouTube videos to audio format like mp3,m4a and wav etc. with some professional tools or software.

    audio hijack is a pretty simple and free app that will do this as well.
