I'm trying to record lectures or seminars in a classroom or office
space, and then broadcast them online for educational purpose.

For now I use a Olimpus digital voice recorder and my old JVC video
camera, but I think I need a decent mic or something. What can you
suggest to use or to adapt my existing equipments? Bare in mind, once
I have a audio file, I must edit it and be able to broadcast it
online.

Also budget is an issue for me, I can't spend more than $700 or $800.

Thanks in advance for your advise.
