Here are a few basic questions to ask yourself
Do I need the ability to create real-time spectrum and transfer function measurements, monitor and log SPL data, and make acoustical measurements to calculate specific intelligibility criteria or RT60?
If YES, you need Smaart Suite, the full-featured flagship edition of the Smaart platform.
Do I need the complete feature set of Smaart’s Real Time Mode, with limited SPL functionality, and do not need Impulse Response Mode?
If YES, then Smaart RT is probably the right choice.
Do I need spectrum and transfer function measurements with no frills or advanced features because I mostly use the default settings anyway?
If YES, then Smaart LE should be a good fit
Do I need to make acoustic measurements, examine reverb times and structure or calculate specific intelligibility criteria (like STI, Clarity, T60, etc.)?
If YES, then you need Smaart Suite. Those capabilities reside in Smaart Suite’s Impulse Response mode and are not included in RT, LE, or SPL.
Do I need significant SPL/Leq monitoring and logging?
If YES, then you must use either Smaart Suite or Smaart SPL.
Smaart RT and LE do not support multiple SPL meters, logging, or any advanced SPL functionality found in Suite and Smaart SPL.
