What the Hell is an Echo Chamber?

Imagine, if you will, a time before computers.  Before there was reverb
software that could be slapped on a source to add space and depth. 
Even way back in the day there was artificial reverb, but it was attained
through more creative means.

One way of achieving this effect was through the use of an echo chamber.
This would be a medium or large room, located somewhere in the studio
building, that had an acoustically reflective quality (usually concrete, brick,
tiled rooms, etc).  Some studios would use their bathroom.  Some would
even use an old elevator shaft.  Anywhere that could achieve a naturally
reverberant sound.

In one of these spaces, there would be a speaker on one end, and a
microphone (or two) on the other.  Then, while mixing, anything that
needed reverb would be sent out of the speaker, into the echo chamber,
then recorded back through the mic (or mics) on the other end.  Finally,
that reverb would be mixed in as desired.

So, long story short, The Atomic Garden has recently gained access to
such a space.  This is very exciting for me because I have a soft spot for
old school techniques like this.

Just below, you will find a quick test I did to see what I could get out of
this 2,500 square foot warehouse space.  In just few minutes, I was able
to set up something that was more gratifying than opening up a reverb
program in my recording software. 

I’m really looking forward to getting to know this old school technique
in the near future.  More tests to come…
