Smaart was first developed in 1995 as a cost-effective software-based solution to audio analysis during a time when the choices for audio analyzers were limited to a small number of moderately to extremely expensive hardware devices – with very limited functionality by today’s standards. The Smaart brand went through a few ownership overlord changes until Rational Acoustics was founded in 2008 with the specific purpose of ensuring the continued development of the Smaart platform while substantially enhancing the educational and support efforts that back it.

  • A system has input and output. Smaart is built to analyze these input and output signals to view their individual level, frequency, or duration components. We can then analyze these signals directly as Spectrum measurements (RTA, Spectrograph) to see what the signals are, or indirectly as Transfer Function measurements (frequency response, impulse response) to see how the signals were changed by the system (input vs output).

  • By doing system measurements in, and of, acoustic environments, we can use those measurements to help figure out how we can adapt our sound systems to our rooms, or vice versa.

  • This extremely powerful analyzer was built to be used when and where we
    actually use our sound equipment – real-time in shops, at install sites,
    during load-ins, and most importantly, in actual show environments

Each edition of Smaart - Smaart Suite, Smaart RT, Smaart LE, Smaart SPL - is defined by which of the above measurements it creates, and to what level of functionality & detail it produces those data types.

  • Sound System Engineers

    use Smaart to measure, verify, optimize, and align sound systems to ensure that sound quality is consistent throughout the various indoor and outdoor performance spaces encountered, from bars and clubs to sheds, arenas, and stadiums.

  • Audio Mix Engineers

    use Smaart to directly monitor the frequency and level content of individual channels from a mixing console, or measurement microphones, to identify problem frequencies, overall tonality and trends, SPL, and other useful information and visual feedback.

  • Houses of Worship

    use Smaart to ensure that each service maintains consistent level and frequency content, and that sound levels are safe, especially where multiple engineer operators are responsible for running the sound equipment.

  • Audio Systems Integrators

    use Smaart to test and verify audio system components before and after installation and ensure that projects meet any applicable specifications or standards prior to project completion.

  • Acoustical Consultants

    use Smaart to characterize the acoustical performance of various spaces for speech intelligibility, clarity, and reverberation to help recommend and design custom solutions and then verify that the integrators and contractors responsible for executing those designs have done so to specification.

  • Live Performance Venue Managers

    use Smaart to measure, log, and remotely monitor and report on Sound Pressure Levels to ensure that artists are staying within designated SPL limits.

  • Sound Rental Companies

    use Smaart to test audio systems before or after they are used as well as sending Smaart rigs with their field technicians to make sure that their audio systems are deployed, optimized, and aligned for each use.

  • Loudspeaker Designers and Manufacturers

    use Smaart to create final alignment and voicing decisions before loudspeaker products are sold or used by end users. Keeping a Smaart rig at the end of the production line helps ensure that products are consistent unit-to-unit after production, before they are shipped.
