Re: [ARSCLIST] analyzing room acoustics to identify recording venues

[Matthew Barton <mbarton@xxxxxxx>]

Not long ago I heard an engineer complain that the problem with current
recordings is that "they're all made in the same room, and that room is
called Pro Tools."

With an acoustic recording, you might use a Time Energy Frequency
(TEF)
waterfall display of the material. A fairly distinct pattern may
emerge.
For a non-acoustic recording that won't work well, because of
artificial
reverb that is added in random amounts. I would think that recordings
from the later 50's and through the 60's you might have some success
though, by identifying the echo chamber signatures of various studios.
They are pretty distinctive, but since the later recordings may have
been tracked in several locations and mixed in several, there isn't
much
to work with there.

I've witnessed this being done for acoustic recordings...I have a
good friend, with an excellent ear, who could aurally identify the
source company of recordings by listening to them!

As far as electric recordings, I can't say specifically...
