Great job Dan. Yes, your audio is not so good. I wonder if you are using a quality mic?
I used an unexpensive computer mic for a while and was surprised that it wasn't too bad
until I hooked up a "better" one (typically anything that has an XLR plug would be
"better". Amazing what a difference. Some post-processing can help reduce all
that mid-range clutter that makes you sound, well, a bit nasal. It's like what is
happening with our videos lately, guys are posting stuff so good it knocks your eyes out,
and with just a bit better gear than we had before. If you want to experiment, you could
send me an audio file and I will see what post-processing can do for it. Keep up the
great work.
