Timed recordings
I record radio programs that are on in the middle of the night, and encode them to MP3. I used to use ecasound for this and schedule with cron. I had problems getting this to work with 64studio, perhaps cron was at odds with the realtime nature of 64studio.
Audacity can be good to use as well, because it can export MP3 directly. I found instructions here about times recordings with Audacity:

Newer Audacity does it!
