I'd say you'd have to include John Storyk and Francis Manzella and
Chris
Pelonis amongst a ton of others who feel (know) that it's the room
that
needs the treatment, not the speakers.

It's always a good practice to start with the room first, but there is
a limitation to how much you can improve the acoustics of a usual
room. Here is where Digital Room Correction enters.

FOR Instance, let's just say that you've scoped out what you feel to be room
correction in an average control room, meaning Joe Blow's place. But he
gets a new piece of equipment in and has to reposition his speakers, so now
your correction is incorrect.

Right, so you'll have to spend another 5 minutes (assuming you have at
least an AMD 2Ghz) in order to obtain the new correction curve. Time
IS money, but let's not push it.

local producer wants to come over and block out the studio for a month to do
pre-production planning on a new group's CD and he brings along his NHT Pros
while you've got room correction set for Tannoy 6.5 PBMs.

Again, 5 minutes and you're all set up to go.


The concept of room correction via EQ (filtration) for specific speakers in
a specific place can work. I don't think anyone is saying that it can't.
What everyone is saying is that it's not a real fix of the problem areas,
which lie within the listening environment in the first place. Once you
understand the nodes and locations, fixing the environment allows you to
virtually replace a speaker setup with another, or add another without the
need to reshoot the room and apply your digital correction to yet another
set of environmental circumstances.

True, but you need to understand the Digital Room Correction is here
to help you, beyond what standard acoustic treatment can do. It's not
a replacement, its an addition.

Sticking a toothpick into a guitar nut may get the guitar to work for a
song, but it's not really fixing the guitar, now is it.

Only problem is, Digital Room Correction isn't going to work for just
one song, but for most songs (situations).

Chris, Room correction by electronics might be a fallacy for your ears
(or understanding), but to mine, and many, many other people, it's
real.

I'm not new to digital room correction, and if I thought it's a
fallacy, I never would have gotten into it. I really like the way it
change the sound for the better, when done right.

People like you really makes me wonder. What satisfaction do you get
by saying this technology doesn't work, before you even heard what it
could do ?. I advise you to reserve your judgement until you actually
listen with your own ears. You might have to eat your hat.

I suppose dozens of other professional reviewers, from respected audio
magazines (whose reviews can be found with ease all over the
internet), who like me, also heard the benefits of digital room
correction, were all deluded, drugged, blackmailed (pick your favorite
choice) prior to giving their sometimes VERY positive reviews.

Anyway, I didn't start this thread in order to persuade people that
digital room correction works. It works very well for me, and that's
what matters. If you could stick to the original question I'll be more
than happy.

In case you only listen from the listening spot (I mainly do this in
my home), once you find the problem frequencies, you CAN fix the
acoustics at the listening spot, using an unlimited band eq, which can
also correct the phase problems which are created by the frequency
correction, and room acoustics.

Well, not really. What you could do, if your speakers were
point sources, would be to correct each speaker's radiation
on one axis, by making near-field measurements and applying
correction. With some extra effort, this can be expanded
to multiple radiator speakers.

So first arrivals sounds can be corrected for listeners
on axis. Any further correction attempted will, by
definition, make *this* correction INcorrect.

Room correction by electronics is a fallacy.
