Smaart v8.5

Smaart v8.5 is the Industry Leading, Dual Platform (Mac & PC), FFT-Based Audio Analysis Software.

Smaart is a computer based dual-channel FFT platform that we use in our work as audio engineers to view the frequency content of signals or measure the response of our electrical and electro-acoustic systems, all to better make informed decisions about the deployment and operation of those systems. Getting started with Smaart v8 requires some basic hardware requirements beyond the Smaart software and host computer. At the minimum, for electro-acoustic systems (PA system analysis), a 2×2 audio device interface and a single measurement microphone will suffice. This is however only the beginning, as Smaart is purpose-built to scale up to fit the requirements of even the most complex systems and environments. The only practical limitation of Smaart is your own – be it expanding your hardware universe, or improving your knowledge through practice and training.

Real-Time Mode: Spectrum Engine

Configure as many single-channel engines as you need, each with the ability to produce its own RTA and Spectrograph data.


  • Fractional-Octave banding, up to 1/48th octave resolution
  • Multi-Channel input allows for simultaneous display of multiple individual RTAs – as well as “live averages” from one or many inputs.
  • “Line-Over-Bands” view of RTA displays both raw and banded data
  • Show Peak-Holds, Target Curves, display THD & calibrated plots
  • FIFO and Integrating Averaging


  • Spectrum-over-Time with amplitude represented by color.
  • Real-Time adjustable dynamic range
  • Scrollable 1000+ line history
  • Adjustable Slice-Height
  • Full Color, or Black & White display

Real-Time Mode: Transfer Function (Frequency Response)

  • Phase, Magnitude and Coherence Plots.
  • Virtually unlimited simultaneous live TF engines, even from multiple interfaces. (Multi-Device Transfer Function engines require sample-clock sync)
  • MTW (Multi-Time-Window) FFT provides better than 48th octave resolution from 60Hz up and 1Hz resolution up to 140 Hz.
  • Up to 1/48th octave smoothing for both Phase and Magnitude plot displays
  • Coherence weighted live or stored data averaging.
  • Delay Tracking automatically measures and adjusts
  • TF delay for every measurement cycle.
  • FIFO and Integrating Averaging

Live IR

  • Window centered at the TF’s delay
  • User-selectable FFT size up to 32k
  • FIFO averaging up to 16 FIFO
  • Display data Linearly, Logarithmically, or as ETC (Envelope Time Curve)
