Smaart (System Measurement Acoustical Analysis in Real Time) is a suite of audio and acoustical measurements and instrumentation software tools[1] introduced in 1996 by JBL's professional audio division. It is designed to help the live sound engineer optimize sound reinforcement systems before public performance and actively monitor acoustical parameters in real time while an audio system is in use. Most earlier analysis systems required specific test signals sent through the sound system, ones that would be unpleasant for the audience to hear. Smaart is a source-independent analyzer and therefore will work effectively with a variety of test signals including speech or music.
The product has been known as JBL-SMAART, SIA-SMAART Pro, EAW SMAART, and SmaartLive. As of 2008 the product has been branded as simply Smaart. An acoustician version has been offered as Smaart Acoustic Tools, however as of Smaart v7.4, Acoustic Tools have been included within the Impulse Response mode of Smaart. A standalone sound pressure level monitoring only version called Smaart SPL was released in 2020.
Smaart is a real-time single and dual-channel fast Fourier transform (FFT) analyzer. Smaart has two modes: Real-Time Mode and impulse response mode. Real-Time mode views include single channel Spectrum and dual channel Transfer Function measurements to display RTA, Spectrograph, and Transfer Function (Live IR, Phase, Coherence, Magnitude) measurements. The impulse response mode will display time domain graphs such as Lin (Linear), Log (Logarithmic), ETC (Energy Time Curve), as well as Frequency, Spectrograph, and Histogram graphs. Impulse Response mode also includes a suite of acoustical intelligibly criteria such as STI, STIPA, Clarity, RT60, EDT, etc.
Smaart has been licensed and owned by several companies since JBL and is currently owned and developed by Rational Acoustics. First written as a native Windows 3.1 application to work within Windows 95 on IBM-compatible computers,[2] in 2006 a version was introduced that was compatible on both Windows and Apple Macintosh operating systems. As of March 2016[update] Smaart was in its 8th version.
