Smaart v8 License Code
RA-SM8LC

Smaart v8 is the industry leading, dual platform (Mac & Windows OS), FFT-Based, audio analysis software. Capable of performing unlimited simultaneous Spectrum, Transfer Function, Impulse Response, and SPL measurements – Smaart v8 is the most fully featured software-based audio analysis program offered by Rational Acoustics.
As a software tool, Smaart v8 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.

Logfile Data

  • Smaart SPL logs all default and user-configured SPL metrics
  • Logfile contains a header for all Max values, as well as any overloads, alarm instances, and user-added notes.
