Correct Your Room and Get Better Mixes Instantly with ARC 2!

Accurate acoustics ensure you mix better, and IK Multimedia's ARC 2 room correction software system helps your control room sound its best. ARC 2 is better than ever, with a completely redesigned interface for simplicity, four-times-greater resolution for even greater accuracy, and the ability to save and recall multiple correction setups. And ARC 2 lets you get set up fast, requiring you to take fewer measurements than before. Whether you've already acoustically treated your mixing room or not, the IK Multimedia ARC 2 room correction software system will help you mix more accurately.

IK Multimedia ARC 2 Room Correction Software System at a Glance:
  • It's easy to integrate ARC 2 into your studio
  • Ideal for any control room
  • ARC 2 offers even more than before
It's easy to integrate ARC 2 into your studio

The ARC (Advanced Room Correction) system measures and calculates the acoustics in your room, then applies correction via an advanced EQ plug-in. Using an included flat-response measurement microphone, ARC 2 software measures your room's acoustics and formulates corrections. The system then uses a frequency/time-correction processing plug-in to work with your DAW, giving you a "corrected" environment every time. If you want the most accurate, optimum room for mixing, use ARC to make it happen.

Ideal for any control room

Ever since you started mixing audio, you've been chasing "perfect" acoustics, right? ARC 2 has the potential to make any room sound more accurate. Think of it this way: if you have no acoustic treatment, you'll encounter all manner of acoustic anomalies like null points, standing waves, asymmetrical reflections, and so on. ARC 2's advanced processing can work wonders in a room like that, and you'll immediately notice a clearer stereo image, more accurate frequency response, and better separation between sounds. Now consider a well-treated room: ARC 2 has the high resolution to iron out any tiny inconsistencies it can find, still leading to a more accurate mixing environment.

ARC 2 offers even more than before

ARC 2 gives you a lot more than the first generation system.More resolution gives you even better low end response, and mids and highs sound even more natural too. You can now select a target EQ curve, to tailor the correction process to your sonic taste. A new Virtual Monitoring feature emulates the sound of different speaker systems to check mix translation, and you can now save multiple correction set-ups for different rooms or mix positions. Basically, ARC 2 gives you even more of the things that made the original ARC system so acclaimed, plus lots of new and useful stuff too.

IK Multimedia ARC 2 Room Correction Software System Features:
  • Acoustic-correction system including native software plug-in and flat-response reference microphone
  • Enhances the accuracy of your studio's acoustics in two easy steps
  • Included reference microphone can be used for ultra-accurate recordings too
  • Enhanced low-frequency resolution, in the range that acoustic problems are most pronounced
  • Mac/PC, AAX, RTAS, AU, VST
  • 64-bit compatible
  • Enjoy better stereo imaging, better detail, and more accurate frequency response
Accurate acoustics can be yours with IK Multimedia's ARC 2!

This software is the truth!

I was skeptical at first about Room Correction Software but after using the IK Multimedia ARC I am convinced. I found that my mixes transitioned better and it took less time for me to mix a project. I don't know if there are other Corrections Software out there but I can tell you this one works and is easy to setup and use.

Skeptics will scoff but buyers will rejoice

I'll get straight to the point, I'm a huge fan of trying as hard as you can to correct your acoustical issues the traditional way: acoustic treatment. This will not take the place of first reflection absorption and bass trapping but, supposing you've taken care of that, this is a life saver. Try as you may, you will not correct modal ringing with absorption. This product really can help massage out the problems in your room. I've found it to help make the room disappear. I was also able to add some low end heft to my monitoring. If you get used to listening to your reference mixes through this system, you will not want to go back.


I agree with all that has been written. Studio monitors that have great specs will fall apart in almost every little rectangular home bedroom studio. Acoustic treatment, especially bass traps are a tremendous help, but can't really address peaks and dips in the lower frequencies, ( I'm just a hobby guy so I may be a little off base on this)? My little hobby studio equipped with the standard Aurelex stuff and yamaha HS 5's works very well. I just accepted that these Yamaha HS 5" speakers wouldn't produce bottom. With my ARC2 in place, its astounding how flat there really are; and I'm hearing the lower frequencies that these can produce! Secondly, I can quickly a/b my mix on several simulated situations such as a virtual car and different speakers. I can sort of average this all out to get a mix that sounds good anywhere. I just wish it could be hooked up to my iTunes on my computer so that the ARC2 could be on all of my listening needs without having to put all of these songs into a DAW session?!? Now that I can maximize my HS5's with correction, can I get the Adams??? lol mitch (Tampa)

Huge Difference

My recording space is about as far from ideal as can be: small room with a dormer space eating up part of the ceiling (makes a good vocal booth, though), speakers set up on the long wall, windows and closet doors... In short, a cramped, boomy room. Acoustic treatment helped to sharpen the image, but couldn't correct for bass boom and mid and treble dullness. I recorded and mixed a twelve song CD in there, but had a lot of trouble getting the music to translate to speakers outside of that room. After installing ARC, which went quite quickly and smoothly, by the way, a pretty shocking response curve was revealed, and corrected. I knew the room accentuated low frequencies and rolled off upper frequencies, but seeing the pre-corrected curve was very instructive. What a pleasure to hear a new mix in a flat environment! Great product.

ARC 2 is a good thing

After years I finally can simply get the mix that I want right here in my room. We don't enough understand how phase problems prevent us from true hearing of the material. ARC 2 is a very smart product and for guys like me (with a limited budget) it is MUST to have one. Thanks to IK Multimedia. God bless you.

Sweetwater Advice

Norb Berninger

A big problem for those of us with a home or project studio has been mixing in a less than ideal room. If you are like me, you are mixing within a DAW through near monitors in a small, boxy room. This produces all sorts of issues - especially in the low frequency range- which affect how I mix. Part of the problem is knowing exactly what those issues are and where they are happening. Furthermore, how do I deal with them, without spending a small fortune, after I have found them? This is where ARC comes in. I have to admit I was slightly skeptical about a program claiming that it can find and correct these issues in such a simple way. But I was pleasantly surprised at the results. ARC is a program you install on your computer. A special microphone measures test tones sent through your monitors and uses MultEQ technology to analize acoustical information throughout the listening area in your studio. ARC combines this information to provide an accurate representation of the room's acoustical problems and corrects for both time and frequency response problems.The final step is to insert the ARC plug-in on the master fader of a project in your DAW and apply the changes. It also shows a visual representation of the frequencies found to be out of balance as well as the ones it has corrected.The plug-in also has a button to turn the changes on and off.This really helped me hear what issues my room has and how I was mixing as a result. While this program is not meant to be a replacement for room treatment or better monitoring, I found it to be very helpful in showing exactly how a room suffers and it offers a way to compensate for these issues. It let me hear how my mixes were being affected and why they were not sounding the way they should.This is a great tool to help those of us mixing in smaller studio environments compete with the big boys!
