You Tube audio capture

I am new to this forum but haven’t found a previous answer. Can I capture the audio from You Tube tutorials? There are some excellent audio and video ones (not necessarily just for Audacity) and I would love to retain the audio tracks for constant use.

Some computers will capture anything playing and send it to Audacity. Some won’t.

If your computer doesn’t have the services or tools listed in the tutorial, then you may have one of the magic computers without all that built-in. For you it’s special software – or the jumper cables if your computer supports that. Most Windows laptops don’t.
