Rational Acoustics SMAART LE (v9)

SMAART LE v9

Smaart LE is an edition of Smaart’s Real Time Mode interface where the measurement settings for Spectrum and Transfer Function are fixed. LE uses the same measurement configuration process standard to the Smaart v9 platform, including multiple simultaneous Spectrum and Transfer Function engines with available live measurement averaging. Smaart LE contains the core, essential, functionality for day to day frequency response measurements (RTA, Spectrograph, Live IR, Phase, Magnitude, Coherence).

If you are a Smaart user and have never changed the settings from defaults, LE is the ideal version of Smaart for you. LE is also a great choice for Students, people starting on the Smaart platform, and anyone who doesn’t require the advanced SPL mode or IR Mode functions found in Suite.

Real-Time Mode

For a majority of Smaart users, Real Time mode is what makes Smaart smart. The single channel Spectrum, and dual channel Transfer Function measurements are essential tools for professional sound engineers all around the world. Real-Time Mode is specifically designed for sound system engineers to be able to accomplish their alignment and optimization work quickly, efficiently, and effectively.

SPL Limitations

Smaart LE allows for calibration of any and all inputs for SPL, and calibrated spectrum measurement. LE offers a single, read only, SPL meter in the main interface for viewing common SPL values without all of the advanced SPL mode features like logging, reporting, alarms, etc.

Smaart RT vs Smaart LE

Both Smaart RT and Smaart LE offer the same multi-input, multi-output, multi-measurement capability. Where they differ is in the depth of settings and advanced user functions. RT is the exact same RT mode as Smaart Suite. LE is a stripped down version of RT.
