CastBlaster, the much-hyped podcasting app from Adam "The Podfather" Curry, is now available in beta form. CastBlaster looks to eliminate the post-production from creating a quality podcast by allowing you to queue up music and sound effects and manage audio levels easily. David Jackson did a screencast review of CastBlaster that’s worth watching, or you can head straight to the beta download. Unfortunately, it’s not freeware: you’re limited to 10 minutes of recording unless you buy a license key.
