Researchers utilize the software for tasks such as testing active noise control systems for urban traffic noise.
In the world of professional audio engineering, sound system design, and acoustic measurement, one name stands above the rest: . Developed by Rational Acoustics LLC, Smaart (System Measurement Acoustic Analysis Real-time Tool) is the premier software for visualizing and analyzing the behavior of audio systems.
While v9 is the present and future, represents the mature, stable, and battle-hardened version that powered countless tours, festivals, and installs throughout the 2010s. Its legacy is a generation of engineers who learned to see sound as clearly as they heard it.
The heart of Smaart is its ability to deliver accurate magnitude and phase responses. The Transfer Function calculates the transfer function between two signals, allowing users to see how to align system components, such as a subwoofer array with main loudspeakers, in terms of both frequency and time. 2. Multi-Channel Measurement Capability Smaart V8

The software operates using two primary measurement engine types:
Using the Impulse Response mode, engineers calculate the STI (Speech Transmission Index) indirectly. By looking at the clarity of the impulse peak versus the reflections (Early to Late energy ratio), they can advise on acoustic treatment or re-aim speakers. Researchers utilize the software for tasks such as
(developed by Rational Acoustics) stands as the world's premier audio analysis software, serving as the industry standard for system engineers, live sound technicians, and acoustic professionals. It is a powerful, dual-channel FFT (Fast Fourier Transform) analyzer used to measure, analyze, and optimize sound systems.
By comparing these two signals, Smaart V8 eliminates the influence of the source material and shows you purely the transfer function of the room and the sound system. It answers three critical questions:
The V8 interface is designed for high-resolution screens and quick navigation. Key features include: While v9 is the present and future, represents
Unlike performance microphones, measurement mics feature an omnidirectional pickup pattern and a flat frequency response. Common budget options include the Rational Acoustics RTA-420 or Beyerdynamic MM1, while premium setups utilize calibrated options from Earthworks or iSEMcon.
The software allows users to customize their view. You can have multiple RTA and Transfer Function windows open at once, allowing for a comprehensive view of the system's performance. 3. Integrated SPL Measurement
Recognizing the shift in computing trends, V8 was built with modern hardware in mind. The interface was made touchscreen-friendly with user-configurable command buttons, catering to the increased use of tablets and touchscreen computers in live sound environments. It also offered native support for high-definition displays and improved performance on modern operating systems. A Remote API (Application Programming Interface) allowed one copy of Smaart V8 to act as a host to another copy on the same network, opening up new possibilities for remote control and complex measurement setups.
Before its launch in March 2016, the professional audio world eagerly anticipated the next iteration of the industry-leading Smaart platform. The previous version, Smaart v7, had been a staple for system engineers since 2010, but the industry had evolved. Professionals demanded greater flexibility, a more intuitive workflow, and the ability to adapt the software to increasingly complex measurement scenarios. Rational Acoustics responded to these calls by developing Smaart v8, a version designed to be the "most powerful, flexible and adaptable version" of the software to date.
At its heart, Smaart V8 is a dual-channel, FFT-based analyzer. It allows users to view the behavior of an audio system across two primary domains:
