About this item



Rational Acoustics SMAART Suite

Smaart Suite is the full-featured flagship Smaart program,  including all three industry-standard measurement modes (Real Time, Impulse Response, and SPL), with no functional limitations.

Suite is the edition that most closely matches the functionality found in Smaart v8.

One Interface, Three Modes

Smaart Suite contains all three Smaart modes: Real-Time, Impulse Response, and SPL. Each mode has a data register, plot area, and control bar associated with it and shares the overall program configuration, command, and control structure.

Real-Time Mode

For a majority of Smaart users, Real-Time mode is what makes Smaart smart. The single channel Spectrum and dual channel Transfer Function measurements are essential tools for professional sound engineers all around the world. Real-Time Mode is specifically designed for sound system engineers to be able to accomplish their alignment and optimization work quickly, efficiently, and effectively.

Impulse Response Mode

Unlike Real-Time Mode which primarily displays measurement data in the frequency domain, IR Mode excels at displaying the response of a system in the time domain, with detailed Linear, Logarithmic, and ETC (energy time curve) views, Histogram and Spectrograph plots, as well as frequency response. Acoustical engineers will appreciate IR Mode for its detailed calculations and tables for RT60, STI, STIPA, CIS, and more.

SPL Mode

Smaart’s SPL Mode provides a powerful solution for monitoring, logging, and reporting sound pressure level. With SPL history plots, fully customizable metering, remote-viewing capabilities, Alarms, and Event Notes, customizable ‘traffic light’ meter coloring, logging and report generation, and Class 1 or 2 capability with 10 EaZy hardware – Smaart is the industry’s leading software-based SPL monitoring solution.

Licensing Information: perpetual + Upgrade

A Perpetual License does not expire.  A Perpetual License is billed in full for the cost of the license at the time of purchase and remains valid indefinitely for the specific edition and version of the software you are licensed for.

Perpetual Licenses are delivered via email and must be registered to a Smaart License Management Account (either new or existing) in order to access the installers for your license.

A Perpetual License is refundable within 30 days of purchase as long as it has not been registered to Smaart License Management account or installed on a computer. Once it has been registered and installed, it is non-returnable and non-refundable.

Perpetual licenses of Smaart Suite and Smaart RT come with 2 installation seats and perpetual licenses of Smaart LE and Smaart SPL come with 1 seat. Once a license has been registered, you can purchase additional seats for it through your Smaart License Management Account.

Perpetual Licenses can be upgraded to different editions of Smaart within the same version cycle (i.e. upgrading from Smaart RT v9 to Smaart Suite v9), and to subsequent versions upon their release (i.e. upgrading from Smaart Suite v9 to Smaart Suite v10). You do not lose your previous license when you upgrade.

An internet connection is required for the initial activation of a Perpetual License and for receiving updates. Once activated, Smaart perpetual licenses can be operated offline.

Support, including updates and bug fixes, is provided at no cost for the duration of the license as long as the version of Smaart you are licensed for is the most current release.

Licensing Information: Subscription

An Annual Subscription License starts on the day payment is received and continues for a period of one year. Annual Subscription Licenses are billed in full for the entire year at the beginning of the subscription period. Auto-renew is automatically selected as the default setting for the subscription and at the end of the subscription period, you will automatically be billed for an additional one-year subscription at then-current pricing.

Annual Subscription Licenses are 1-install only and additional installs cannot be purchased for, or added to, Subscription Licenses. If you wish to run Smaart on more than one computer, you will need to purchase a separate Annual Subscription License for each computer.

Annual Subscription Licenses require a periodic internet connection for license validation and renewal.  If the computer on which your software is running is not connected to the internet at least once per month, your software may cease to function.

You can cancel your subscription from within your Smaart License Management account any time up to 24 hours prior to the end of the current subscription period and you will not be billed for future subscription periods. You will not receive a refund for any portion of the fees paid for the current subscription period unless legally required.  See our Cancellation & Refund Policy for further details.

If you cancel your subscription, your Annual Subscription License will remain active, and you will be able to use Smaart, until the end of the current subscription period. Once the subscription period has ended, your Annual Subscription License will expire and Smaart will cease to function.  If you wish to continue using Smaart, you will need to purchase a new Subscription License.
