Smaart I-O released

We are proud to announce that the Smaart I-O is now released.

The Smaart I-O is a measurement-grade 2×2 USB audio interSmaart_I-O_3qtrsmall.pngface designed and built specifically for use with Smaart v.7 Measurement Software.  The I-O features two high-quality, active balanced inputs with 50 dB of software adjustable gain in precision 1 dB steps.  The input gains are monitored directly by Smaart allowing the user to retain accurate SPL calibration while varying measurement signal input levels.

IO_Ctrl_AppSingle.jpgA simple control program, included with the product (or available from our website) sets preamp gains and phantom power selection, and automatically integrates with Smaart v.7. The control program also provides firmware update capability and can rename the Smaart I-O at the hardware level – an important feature when using multiple devices with Smaart.

NOTE:  Owners of the new Smaart I-O must update to 7.3.2 to ensure that gain reporting and microphone sensitivity calculations work properly.  To update to the latest version of Smaart, log-in to your license management account at and download the latest installer.

Please click HERE for full information on the Smaart I-O, including links to the I-O Spec Sheetthe I-O Manual and the “Using Smaart with Gain Reporting Devices” app note (manual and app note are also included with the product on CD-Rom).

The Smaart I-O is available for purchase via our online store. US Retail price is $549 USD.  Or you can contact your local Rational Acoustics Dealer or Distributor for local pricing & availability.

The Honorable John Aldrich

Boy Wonder

Phone: +1 860-928-7828

John joined the Rational Acoustics clan in January 2011 to take on the task of managing all things support-related. This means he’s one of the guys on the other end of the phone or e-mail when you contact us to say that Smaart is suddenly no longer playing nice with your i-o device or that you got the dreaded error code 543 and are now freaking out. He’s also the guy who runs Smaart development projects and gets to shake out new software release candidates and try to break them.  And in his copious spare time he also manages the bug reporting & beta tester program.

John is a computer suuuper-geenius. Don’t let him tell you differently. He’s got no less than 5 Mac Pro’s at his house that he does unspeakable modifications to,  just for fun.

Little known fact about John…even though his name is spelled j-o-h-n, it’s pronounced Karl.

Smaart v.7 Video Library

We have just finished the first set in a series of new Smaart v.7 support videos.

These first 3 videos cover the basics of getting your Smaart v.7 license registered, installed and activated, as well as releasing and restoring a license on the same (or different) machines.Eventually we will have a whole slew of videos covering everything from licensing/registration to basic smaart configuration & measurement to specialty topics like “looking at comb filtering”, etc…  Jamie is working on them as we speak.

You can subscribe to the Rational Acoustics YouTube Channel to be notified whenever a new video is available.

Smaart v.7 released

After 2 years of development, over 150,000 lines of code and gallons of blood, sweat and tears we are happy to announce that Smaart v.7 is now ready for initial release!

Smaart v.7 is available for online purchase immediately .  You can also download a 30 Day Demoof Smaart v.7 (please be sure to read the “ReadMe” doc on the demo download page).

Users can purchase new licenses or upgrade licenses from Smaart versions 4, 5 or 6.   If you are upgrading from a previous version of Smaart, be sure to ahve your previous version license number handy. As a reminder, Smaart v.6 licenses MUST be registered at prior to upgrading to v.7.  (if you registered your license at, your license and account info has been transferred over to and you should be able to log in with the same e-mail address and password that you used to initially register your license).

Upgrading online is the quickest and most efficient method of upgrading.  However, we do understand taht there are some users who cannot do an online purchase.  If you must pruchase a license (either upgrade or new) offline you can do so by contacting us direclyt at +1-860-928-7828 or  International users can purchase licenses directly from your local Rational Acoustics distributor.

Hard copy CD packages of Smaart v.7 (new licenses only) will be available for purchase via our online web store in approximately 2 weeks.  Please check with your local distributor for availability of hard copy CD packages.

If you purchased Smaart v.6 after June 1, 2009, you are entitled to a free upgrade to Smaart v.7.  To claim your free upgrade, please go to the online purchase page and click on “Upgrade License”.  Enter your v.6 license number and it will take you to an order confirmation page with a zero-dollar ($0) transaction (don’t worry, even though it asks for “billing info”, you won’t be asked for any credit card info..).    Once you have completed your order, an e-mail with your new v.7 license and installer links for both Mac and Windows will be sent to you.

The feature set in this v.7.0 release of Smaart represents what we feel to be the minimum for initial release.  However this is nowhere near the end of Smaart v.7 development.  “After dot” releases with new features and updates will continue to be released on a regular basis throughout the coming weeks, months and years.  All new releases and updates will be available to Smaart v.7 users through their license accounts at  We have a lot planned for this new Smaart platform – it was built to do some amazing things. So stay tuned !

We appreciate everyone’s contintued support of Smaart and your patience while we created a product that we are proud to bring to market.  We truly could not have done it without you !

Sales and Logistics Superwoman

Known to Smaart users worldwide as “Barb”, Barbara was minding her own business in the service department of EAW when Jamie came along in 1999 and convinced her to work in the new SIA Software division handling Smaart sales logistics. And just when she had almost forgiven him he did it again in 2009, convincing her to come work for Rational Acoustics.

Over the past 13 years Barb has looked up more licenses, issued more PIC codes and shipped more Smaart packages than anyone on the planet. This makes her invaluable to all of us here at Rational as well as to every Smaart user who’s ever had their computer fried by an errant beer at a gig or washed that little piece of paper in their pants pocket where they had written down their license code.

Little known fact about Barb…. don’t piss her off.
