Nursing student here. I record lectures so review them at high playback speeds, and to share with classmates who aren't able to make it to class.
I've been using the small clip-on battery powered mics made for doing interviews, but last semester revealed a few weaknesses: The profs don't like to actually wear them, so I just clip them onto the lecture podium - works fine while they're standing at it, but they don't have good range, and most of the profs move around a lot as they lecture, so the volume of the recording is all over the place or completely silent if they stray too far away. Also 99% of the time a student asks a question, the mic doesn't capture it at all, so I just get a few seconds of silence followed by some random info with no context. The battery is also only enough to get through about 2/3 of a class period - fine if I remember to swap them out during a break, but not ideal.
Going forward, I'm hoping to find an option I can just plug into my laptop, sit near the front, and record. A normal desktop conferencing style mic stands out as a decent option, but thinking of the range issue I'm having with the portable mics, I suspect a conferencing type product will have the same issue since it's made to record sound coming from like two feet away from the mic.
I've seen like giant fuzzy mics used on movie sets - should I look for something like that?
And are there specific product recommendations you'd make that are on the less expensive end of the spectrum?
Thanks all!
Edit-
Thanks for all the feedback folks! Time to dig through reviews.
Short of a range of mics with recording equipment and a crew to operate them, nothing is going to handle all these issues.
The best option is a hand-held digital recorder that you can leave at the podium or wherever is the closest spot. There are a large number of devices designed specifically to record lectures for college students. I highly recommend you research those and skip trying to record directly to your computer.
Wireless mics are just adding a range of issues for you when you can spend that money on a more robust recorder. You will find yourself spending more money on a less specialized and poorer performing setup than just buying the right portable recorder.
Sony and Zoom (not the telepresence company) are some notable leading brands for these devices.
Edit: the H1N and UX570 are highly regarded.
