Podcasting from Linux

Podcasts are reinventing talk radio on the Web. These homemade audio downloads have become popular since they were introduced last year. Pontificate on your political opinions, praise your favorite bands, interview your hero — the possibilities are limitless.
Podcasts were created by fans of the Apple iPod, but you don’t need an iPod or a Mac to make your own. Properly configured, the average Linux distribution can podcast with the best of them. Here’s how.
Before you start practicing your radio voice, make sure that your system includes the following programs:
Audacity (sound recorder and editor, included by default with most distributions)
Lame (MP3 encoder, available through RPM or APT)
iPodder (subscription tool — see install instructions below)
Skype (VOIP client, optional for recording interviews through VOIP, available through RPM or APT)
On the hardware side, you’ll need:
A microphone
A pair of headphones
A sound card with a line-in port
If your distribution can handle these modest requirements, it can handle podcasting.
Listening with iPodder
Essentially, a podcast is an MP3 file paired with a syndication feed. iPodder is the most popular subscription tool for these feeds. The program incorporates an RSS (Really Simple Syndication) reader and a simple download agent to grab the feeds that you select.
The Linux version has come a long way, but it is still in beta. An RPM package is available directly from iPodder. Before you install it, make sure your machine is running the latest version of wxpython.
For Debian-based distributions, iPodder installation is a little more complicated. iPodder isn’t available through APT, but an alien conversion worked straightaway on my Mepis Linux machine. Open a terminal, move to the RPM’s directory, and type the commands:
alien –to-deb ipodder-1.1.2-1cl.noarch.rpm
dpkg -i ipodder_1.1.2-2_all.deb
