You might be surprised at what a little effort in Audition, Audacity, = or similar tools can do pressing capture noise print, select all, and act= ive noise reduction. Much much greater gain than a $300 bump in mic quali= ty - and cheaper too.

Thanks, I will try that.

The problem is what's been posted is audibly terrible. How it is remedied, whether by better equipment or via post-processing (and note, I have several professional sound packages and equipment, etc.), is the issue and, INMSHO, it should be addressed for the future for such historic, one-time, lectures.
