Smaart Measurement Software

a brief history of Smaart

System Measurement Acoustic Analysis Real-time Tool

Rational Acoustics Smaart sets the industry standard for sound system measurement and alignment—whether at festivals, concert halls, theaters, or on tour with world-renowned artists.

Smaart is a dual-channel, FFT-based analysis platform designed to measure and optimize sound systems and room acoustics. With its powerful toolset, you can diagnose issues, analyze system behavior, and improve overall audio performance. The software runs on both Windows and Mac and is trusted by professional audio engineers worldwide.

Using Smaart, an engineer can clearly see how equalizers, delays, loudspeakers, and room acoustics affect the audio signal. This insight makes it possible to fine-tune a sound system to match the acoustic environment—or even adjust the environment to better support the sound system..

System Measurement

Every audio system has an input and an output. Smaart is designed to analyze both, letting you inspect each signal’s level, frequency content, and time-based characteristics.
You can measure these signals directly with Spectrum tools such as the RTA and Spectrograph to understand what the signals contain.
Alternatively, you can use Transfer Function measurements—including frequency response and impulse response—to see how the system changes the signal from input to output.

Acoustic Analysis

By measuring how sound behaves in different acoustic environments, we can better understand how to adjust our sound systems to the room—or adapt the room to the system—for optimal audio performance.

Real-Time Tool

This powerful analyzer is designed for use exactly where sound equipment matters most: in real-world, real-time environments. Whether you’re in the shop, on an installation site, during load-ins, or right in the middle of a live show, it delivers accurate, immediate insights when you need them most.

Each edition of Smaart – Smaart ST (Suite), Smaart RT, Smaart LE, Smaart SPL – is defined by which of the above measurements it creates and to what level of functionality & detail it produces those data types.
