Recording audio from internet radio sites can be an easy enough task. All you'll ever need is a fast internet connection, along with a recording application, and lots of free hard disk space. The internet connection should be fast so as to minimize choppy frequencies of the radio broadcasts. Also, lots of free hard disk space is a basic requirement since you'd be recording streaming audio more than you think you would. Finally, choosing an audio recording software, specifically one that could compress the audio files while maintaining high quality, is a must.
