To create the most compelling, engaging content with Articulate Presenter, you will likely want to record narration. The only requisites for doing so, of course, are that your PC have a sound card (only if you use an analog mic; USB mics do not require a sound card) and that you have a microphone.
But what kind of microphone?
Although any type of microphone will work for recording audio — an analog mic with standard 1/8″ input or a digital USB mic — Articulate recommends a USB mic for optimized recording quality.
We do not officially endorse or sell any microphones, but the one we do recommend for Windows XP or older (and with which we’ve had the best results) is the Plantronics DSP-400.
Windows Vista users: The Plantronics DSP is not compatible with your operating system, but don’t worry — Microsoft maintains a Vista hardware compatibility list. We’ve also had good success with and recommend the Samson C01U USB mic and the Samson Go Mic which is portable and sounds great. Here’s a screencast that lets you hear what it sounds like.
