I just finished recording the as-yet longest http://perlcast.com/ "news" segment. I'm sure Josh will have it up on the site within a day or two (update, at http://perlcast.com/2007/04/26/perl-news-2007-04-27/).
Josh does a great job getting me a list of things to read. The fun part is that I can do it as time permits, which usually means "late".
Before my Macbook Pro, I had to record the audio pieces using Quicktime Player, then bring them in to Garageband to edit. Now I can record directly in Garageband (without getting the dreaded "we ran out of CPU power"), saving me some time.
Once I get the raw audio recorded, I go back and drop in the "stingers" between the segments. One listener wrote in and said they sounded "kitchsy", to which I responded that this means I succeeded, because that was the sound I was going for. In dropping in the stingers, I sometimes have to stretch or shrink the gap, but I usually hit the gap dead-on while I'm recording the news in one take, so the work is minimal.
For this 10-minute news result, I think I spent about an hour on it, but it's an hour I'm happy to spend if it helps the Perl community keep more in touch.
