Listening to it back now using the link I posted and it sounds just fine to me.....maybe I'm not the only one with audio issues. lol
It has a ton of bass, which "blocks" or "masks" the intelligible speech range. I don't have a convenient highpass filter at the moment; that might clear it right up, as would a set of 1/2" laptop speakers that are barely capable of the intelligible speech range and not much else.
Do be aware that some people watch your content on rigs that are easily capable of delivering a "personal rock concert" in terms of volume and frequency response, and they don't necessarily have any more control of it than just volume. They won't reproduce something that you don't send them, so try not to send them any more than what you actually intend.
The typical thing to do in live audio, is to run a separate highpass filter on absolutely everything (including bass instruments), and set each one by ear to as high a frequency as you can get away with, without actually affecting the intended sound. (bass instruments will have it set lower, sopranos higher) And sometimes I've intentionally set it high enough to make an audible difference, to try and clear up a mumbling junior-high actor in a play for example.
Aggressive highpassing takes care of both "stage mud" and the mics' "proximity effect", which causes all directional mics to become more sensitive to lower frequencies when they're close to the source.
