I recommend the Podcast Generator on SourceForge.net created by Alberto Betella. It's open source, so please contribute financially if you use it.
What's cool about it? It gives you options to offer RSS feed for others to use and to send your podcasts to iTunes. I'm at the Cluecon conference in Chicago this week. I met a guy at the iCall party last night who had on a tshirt from a conference that features science fiction and open source. He stated, "I downloaded all your DIDX podcast interviews and listened to them on my drive from Wisconsin to Chicago yesterday. Your enthusiasm is infectious and feels sincere. How do you get that stereo sound? I have some ideas for clearer sound..."
(Thank you! I'm really inspired and interested in the people I interview: Allison Smith, Jaymie Scotto, Omar Chohan, Bernd Wiegmann, Leif Madsen, Luca Filegheddu, Joel Driver, Jonathan Leong, Roman Khalenkov, Harmon Wilfred, David Mandelstam, Michael Schelin, Maria Gomez, Dilawar Syed, Art Smith, Michael Collins, Carol Davids and Warren Bent, Atiq Rehman, Shomail Dan Muhammad, Brian West and Anthony Minessale, and Rabah Djanati.
I explained that I use a variety of voice over Internet services from among our 12,000 or DIDX customers and suppliers. I'm experimenting with those and with different audio settings on my Toshiba. One example, some of the interviews use Skype for voice and PrettyMay to record. When I call to a PSTN line from Skype, the quality is not as good as when I call from Skype to Skype.
He gave me some great ideas to follow up on to improve the sound of our podcasts. When I find his business card, I will credit him more fully here on this blog post.
My attention goes back to Gemeinschaft German PBX presentation at Cluecon. Stefan Wintermeyer is not only technically savvy, but his presentation is the most interesting I've seen yet. (More conferences that are IP communications-related are at http://www.didx.net/events.
