A client and I are getting more serious about recording audio/video educational courses for presentation on the web, and we're wondering now about the ideal microphone to use with regard to price, quality of the sound, and mobility. For completeness in describing our situation, we typically record with two high-quality USB cameras with built-in mics using Wirecast on a PC.
The ideal theoretical solution would be a wireless lavalier/lapel mic, but I've not yet found an obvious product that fits AND fits within budget. I like the looks of this one: http://www.amazon.com/Azden-WMS-PRO-Wireless-Microphone-System/dp/B00006JPD8/ref=sr_1_14?ie=UTF8&qid=1333945783&sr=8-14
The main concern with the system is whether or not we can plug it directly into the line in/microphone jack on the laptop we're using for recording. Eventually, of course, we'll be upgrading to much higher quality video cameras, but for now, this is what we've got.
Considering that most of our recording is done in classroom-style settings, and that we can place equipment near the speaker on a podium or desk, would a more standard, wired microphone be a better solution? I'd imagine it definitely would be for price, but what about the audio quality? Will we see significantly better results from a desktop mic to begin with?
Thanks for your advice! If I can better explain our various recording scenarios or needs, please let me know.
