Carpet is, of course very bad for recording in that it does not 
reflect frequencies evenly. It acts as an uneven filter, eliminating 
some of the higher harmonics, while leaving others in place.
The most obvious effect of this on the lute is that the harmonic 
signature of the treble will be different than that of the bass, 
making the bass sound like a different instrument, or the treble will 
lose its sparkle.
Another effect of the carpet is that the bass will last longer than 
the treble. That is becuase the treble is being dampened, but the 
bass is not. Such recordings can be EQ's to even them out, but it is 
often very difficult becuase the reflections are not dampened evenly.
Many lute recordings have a kind of amped, boomy bass due to uneven 
reflections in the recording room, although some of this is added 
later because the "default" setting on any commercial reverb box uses 
a bass multiplier of 1.5X and no one ever dials it down
We are the bass boomer generation.
Although this is a complex subject, the minimum thickness for 
acoustic material is approximately four inches.
A far better way to reduce reflections in a church is to use 
figure-of-eight microphones. Most multipattern studio mics have such 
a setting. This pattern eliminates most reflections from the floor 
and walls, whilst retaining an open, transparent omni-like sound.
My Neumans have a variable pattern, so by rotating a dial you can 
adjust the ambience to taste withought using artificial filters, but 
any good figure of eight, or a well made hypercardioid, such as the 
Schoeps MK41, will produce a beautiful, detailed and balanced sound 
in a church.
I aslo consider that loose music paper on a wire stand will act as a 
resonator, so I always try to use solid stands and bind the music. 
Some would, and reasonably so, say that is a bit too OCD, but buzzes 
and a rattles are a common problem in recording.

So, ditch the carpet, move in the bookcase or sofa, especially a 
Chesterfield (h/t to Dirk Gently)
