Assuming you are looking for Windows...
Streamripper:
http://streamripper.sourceforge.net/It is a command-line tool, but there are some graphical front-ends to choose from:
http://www.stationripper.com/http://people.umass.edu/jvight/SimpleRipper/That will just capture the live streams.
For editing, Audacity is the best tool out there:
http://audacity.sourceforge.netThere are probably some non-free commercial tools that I am not aware of that do everything in one package. Possibly even some other free all-in-one packages.
Hope this helps, Rob.
