Recording a large group with brass accompaniment inside a somewhat confined area 
with a single stereo microphone presents some challenges that are hard to overcome.
The best place for the microphone would be in a location that's roughly equidistant
from all sound sources, but with the organ's pipes essentially in another room and
with a baffled ceiling above the choir (which generally reduces bass frequencies),
coupled with the power of a half-dozen brass players and kettle drums, it's
a bit remarkable that a listenable recording of any sort can be produced. 

So as an experiment, I used some software to "enhance" two of the recordings.
This was an attempt to reduce some of the problems associated with the placement
of the microphone, which was located immediately to the right of the soprano
section on the paneling along the choir organ pipes (which must have been muted).
Obviously this isn't the best place for a microphone but with few options available, this
placement helps to minimize the overly loud brass as from that location, the horns
are pointed away from the mic instead of directly at it, which would be the case
had the microphone been placed on the director's podium. As the original recording
was pretty flat with no reverberation, I also attempted to add a little more "church 
ambiance" in the form of reverb and echo, which then dampens the concept of stereophonic
sound. I also boosted the lower (bass) frequencies while cutting some of the high (soprano)
frequencies because of the location of the mic, which was immediately adjacent to the soprano
section).

"Enhancing" sound after-the-fact is never great, but it resulted in a passable and somewhat
more balanced recording than the raw recording. Is it good? No, not really, but given the
circumstances, it's about as reasonably good as I could make it. In any event, it was an
interesting experiment.
