Well that would definitely explain the sq/balance, especially the lack of vocals. That's a pretty standard part of recording on stage, definitely comes across in the camera recording too, although that one is a little brighter
Thank you again for your comments.
Sorry, I probably wasn't very clear in my previous post -
the video was from an entirely different date (over 4 months ago) and different venue -
it was much, much bigger (a hall), and definitely no where near packed the way the audio recording venue was -
in fact it was pretty sparse.
From the video one can see I was much further back from the stage -
if the video's audio sounded even vaguely similar -
that means their regular sound balance does seem to have the vocals recessed,
and makes that Tascam DR-05 audio only recording remarkable,
that under the ridiculous circumstances -
it could even manage to achieve a balance comparable to a recording (video) that was much less handicapped.
