Acoustics and room response are frequently overlooked during the mixing
process. You may be familiar with the likes of bass traps, foam shapes
and high-end products like diffusers, but there are downsides to
traditional acoustic treatment methods such as these.

If you dont know what youre doing, its not easy to use them
effectively, and they aren't always suitable for people using rented
space, those who mix in many different environments (such as laptop
musicians or roving engineers), or, indeed, musicians whose studio
overlaps with their living space.

A room's 'response' refers to how the acoustics and the speakers
interact with each other. Obviously, as flat a response from the room
as possible is ideal, so that you don't overcompensate in your mix for
any frequencies that the room absorbs, or cut any that it enhances,
thus creating something that's unbalanced on other systems.


Seemingly spotting a gap in the market, IK Multimedia has teamed up
with Audyssey Laboratories to produce the ARC System (ARC stands for
Advanced Room Correction), which is aimed squarely at improving the
sound of your mixing environment, whether you already have acoustic
treatment in place or not. The package consists of a plug-in to run
inside your DAW (which always needs to be inserted last in the chain on
the master bus), a separate measurement program and a reference
microphone (which also doubles as a decent recording mic) in a carry

Powered by Audyssey's existing MultEQ technology, ARC is designed to
provide a wider 'sweet spot' and to correct multiple listening
positions rather than improving just one while compromising others, as
is often the case with conventional EQ. IK boasts that, unlike other
systems, it corrects frequency and time domain issues (such as
phasing), while keeping within the inherent frequency limits of your

Before you can use the ARC plug-in, you have to pull out a mic stand
and get the measurements out of the way. To avoid soiling the results,
you must use a clean, uncoloured input channel with phantom power for
the measurement mic. Also, ARC is calibrated to work only with the
supplied mic using another model will give inaccurate results

The measurement software is a standalone application and is extremely
easy to operate, with on-screen instructions. At step three, you set
the required volume for the test signals that the software pumps out to
analyse your setup, before step four, where measurement proper begins.

Its essential to take the initial measurement from the centre of your
listening position and then in an alternating left/ right symmetrical
pattern, which is actually easier than it sounds.

You need at least 12 measurements to proceed to the last stage, where
the compensatory EQ curves are generated and stored for use, but you
can take up to 32 for more precise results. Each curve can be given a
name and a picture of some speakers assigned to it handy when using
multiple monitoring setups.


To evaluate ARC, we started in 'studio one' - a small room, about
11x10' with a low 7' ceiling, carpet and some acoustic treatment
(diffusers and two bass traps). Monitoring comprised a pair of Alesis
Monitor One MK2s with a Genelec powered sub (ARC works fine with subs,
by the way), which is a typical project studio setup with a balanced,
neutral sound.

We did three tests in studio one; the first with the minimum of 12
measurements in the listening position, and the second with the full
32. For the final test, we compensated for two positions, with 20
measurements at the listening spot and 12 further back in the room -
similar to the 'client couch' position described in the ARC manual.

We also put ARC through its paces in 'studio two' - a larger room at
20x16' with a high 11' ceiling. This room was bedecked with heavy
drapes on the back and side walls, and the listening spot was quite
close to the speakers, so room anomalies were less of a concern. The
'monitoring' in this instance, however, constituted a pair of trusty
old Mission 701s, which, while great for pumping out tunes, aren't
intended as studio monitors, and so provided a good test of whether ARC
can work its corrective magic on the speakers themselves.


In studio one, ARC really tightened up the response across the board
and put paid to the low-end problems thrown up by the dimensions of the
room. Although all three tests gave slightly different results, the
frequency graphs showed a clear trend caused by the small room.

Over in studio two, while ARC didn't transform the Missions into true
reference monitors, it did flatten out their tone and tamed their
slightly skewed lower-midrange, making them more suitable for musical

In both environments, the sound became more consistent across the
measured sweet spot, and when moving around the listening position, any
annoying, 'swimmy' phasing was virtually eliminated. Transients became
tighter, and the high-end snap of kick drums seemed to connect better
with their low-end 'oomph'. ARC offers four different target EQ curves
to tailor the sound, and we found that the Mid Comp option (with a dip
at 2kHz) worked best in both situations.

Overall, the ARC System offered real sonic improvements and gave us greater confidence in mixing.

The final acid test came when we compared the adjusted monitor sound to
the legendary AKG K240DF studio reference headphones, which boast an
extremely flat response. It was apparent that ARC had indeed coaxed a
similarly neutral tone from the Alesis monitors.

Disadvantages of the ARC System are that you can only enjoy its
benefits when the plug-in is active, and so not when using, say, a
regular media player application. Some might feel that it's a little
expensive, too, especially when they consider that KRK's forthcoming
ERGO system costs not much more and is an 'always on' hardware
solution, audio interface and monitor switcher to boot (although, of
course, we can't yet vouch for the quality of its room correction).
Then again, you can easily spend far more on conventional acoustic
treatment products.


If youre serious about getting as accurate a sound as possible from
your mixing environment, you won't go far wrong with the ARC System. It
will be especially valuable if you can't acoustically treat your room
to a sufficient degree in the conventional manner, or if you need
portability. IK_Multimedia_ARC_System_VST_RTAS_v1_0_2_Keygen_AiR_13MB_rar
