Okay, I know I may be fighting a losing battle, but I want to check to see
just how much of a problem I may really have.

I'm lately relegated to trying to mix in a room that is basically
12'x10'x8'. There is an open closet on one wall, full of shelves of cables,
etc. There are bookshelves on two of the other walls, with furniture under
them. The other wall has a large window on it, and my mixing station in
front of that. The closet is to my left as I sit at the desk.

The acoustic treatment I have so far is comprised of old cubicle wall
partitions...the type used by every computer industry on earth: cloth
covered foam of some kind. These have made the room a place where I can
actually record without hearing the room in the mics. But for mixing, I'm
not sure.

Two of the 4'x6' partitions are basically flush against the wall. Two of
them are hanging from the ceiling, angled such that they're about edge near
the middle of the room is about 8" off the ceiling, near the walls they hang
down about 14". Two more partitions are in the corners next to the window,
behind the mixing desk and behind the JBL LSR28's that I use as monitors.
These partitions cross the corners, making a triangular space behind them
that I've filled...on one corner with a down comforter, on the other corner
with old sleeping bags.

There are no diffusors in the room right now, and no real acoustic foam.
The treatments I have have, as I said, helped enough to make it possible to
record in the room. But I am wondering if treatments take care of
modes/standing waves? Is it possible to make a room like this a place that
you can get an accurate mix, particularly in the 50-250Hz range?
Suggestions? I already augment mixing with a set of Grado cans, but it's
just not the same.

Thanks!
