Streamers for Mac

From Christian Turner:

Streamers automates the process of recording audio streams, using Ambrosia Software's WireTap, and converting them to .m4a or .mp3 in iTunes. You can build a list of streams to record immediately or to schedule for later recording. The program also lets you maintain a library of shows that can be recorded on a weekly, monthly, or daily basis. (Streamers uses iCal for scheduling.)

I use this to maintain the latest of various NPR shows on my ipod. Some of these are included in the Library by default.

Note that by default iCal will open Streamers two minutes before a recording is scheduled to begin. Two minutes later, you will see Streamers load the scheduled Task List and begin your recording.
