I admit it, I am a complete noob when it comes to audio/video recording. I recently purchased a somewhat cheap USB microphone ($35) to try my hand at recording some screencasts for the DotNetNuke community. About halfway through I realized that there was an annoying buzz in what I was recording. This noise could be eliminated with filters included in the Camtasia product or Audacity, but at the cost of sounding a little bizarre. In fact, I believe I sound a lot like the annoying Monitor/Oracle in Halo that is in charge of the rings.
In order to avoid a repeat in frustration of this video recording, I am planning on purchasing a new microphone. If anyone has any suggestions on which one, I'd love to hear them.
