: Focuses on Spectrum and Transfer Function measurements.

SMAART is software only (no proprietary hardware), but it requires a specific audio interface:

SMAART is not plug-and-play. It suffers from . If you place the mic in a bad spot (too close to a boundary, in a direct reflection), the data is useless. Furthermore, interpreting phase traces requires a deep understanding of acoustics (e.g., the difference between minimum phase and excess phase ).

Smaart is primarily used by audio engineers for of sound systems. Here are the core features:

: Includes all features (RT, LE, SPL, and IR modes).

This is the live engineer's best friend. As you move a microphone around a venue or adjust a DSP (Digital Signal Processor), the graph updates instantly. You can watch a feedback frequency spike or see a subwoofer alignment shift in real-time.
