In this video I will show you how to record audio from an audio stream. Such as from Shoutcast using QuickTime Pro. Now there are many other ways to do this with Freeware like Audacity. That will allow you to crop, edit your audio files.
Of course, because this isn't REALLY a post on your blog, it can't put the link or title of any actual blog post, so I've taken the liberty of making it really easy for you to "please link 2 me" :-)
