The first channel of audio undergoing analysis is connected directly from one of the main outputs of the mixing console and the second channel is connected to a microphone placed in the audience listening area, usually an omnidirectional test microphone with a flat, neutral pickup characteristic. This is used by live sound engineers to set up concert sound systems before a show and to monitor and adjust these systems during the performance. Using its dual-FFT mode, Smaart compares one channel with the other to show the difference. Smaart's transfer function requires a stereo input to the computer because it analyzes two channels of audio signal.

The software works with computer audio protocols ASIO, Core Audio, WAV or WDM audio drivers.
Smaart can be set to sample rates of 44.1 kHz, 48 kHz or 96 kHz, and to bit depths of 16 or 24. A computer having a dual-core processor with a clock rate of at least 2 GHz is recommended.

The latest version of Smaart 8 runs under Windows 7 or newer, and Mac OSX 10.7 or newer, including 32- and 64-bit versions. This feature allows the software to 'ignore' later signal reflections from walls and other surfaces, increasing in coherence as the audio frequency increases. The FFT implementation of Smaart is a multi-time window (MTW) solution in which the FFT, rather than being a fixed length, is made increasingly shorter as the frequency increases. It includes maximum length sequence (MLS) analysis as a choice for impulse response, for the measurement of room acoustics. Smaart is based on real-time fast Fourier transform (FFT) analysis, including dual-FFT audio signal comparison, called "transfer function", and single-FFT spectrum analyzer. As of March 2016 Smaart was in its 8th version. First written as a native Windows 3.1 application to work within Windows 95 on IBM-compatible computers, in 2006 a version was introduced that was compatible on both Windows and Apple Macintosh operating systems. Smaart has been licensed and owned by several companies since JBL and is currently owned and developed by Rational Acoustics. The impulse response mode uses either FFT or maximum length sequence (MLS) analysis. Realtime mode uses dual- and single- fast Fourier transform (FFT) to display RTA, spectrograph, and transfer function measurements. Smaart has two modes: Realtime Mode and impulse response mode. Smaart is an acronym which stands for sound measurement acoustical analysis real time.
An acoustician version has been offered as Smaart Acoustic Tools, and a standalone version containing just the sound pressure level measurement tools is offered as Smaart SPL. The product has been known as JBL-Smaart, SIA-Smaart Pro, EAW Smaart, SmaartLive, and simply Smaart. It is also intended to assist audio engineers in analyzing the output of loudspeakers, audio amplifiers and other audio gear, as well as helping the acoustician analyze room acoustics. Most earlier analysis systems required specific test signals sent to the sound system, ones which would be unpleasant for the audience to hear. It is designed to help the live sound engineer optimize sound reinforcement systems during the public performance.
