View Full Version : Recording in tuned room

I recorded a string quartet last weekend in the 'Music room' of an old
mansion that was recently fitted with central air. To make it less visible
they used the new small jet vents, about 2.5 inches across pushing air out
at high speed. Makes a helluva woosh right behind the quartet almost
under the seat of the cello, but I was expecting that.

What I didn't expect was that the tube acted like an organ pipe to resonate
with the cello on one low note (I think it was a D) giving this hollow,
muted boat whistle of a sound every time he hit that note loudly.

The room was tuned to D.

I can EQ out the volume, but the timbre is still there. No one minds, I'm
going to leave it. Just thought y'all would find it interesting.

Yes, but you can't EQ out the sustain of that note, which is what room
coloration is all about. It's more of a time phenomenon than an amplitude
phenomenon.
