Smaart SPL is a stand-alone SPL monitoring program encompassing all of the advanced SPL monitoring features found in Smaart v8, in a streamlined purpose-built package. Smaart SPL does not perform Spectrum, Transfer Function or Impulse Response measurements.

With an interface designed for simplicity and speed, Smaart SPL provides a powerful and full-featured solution for monitoring, metering, and logging SPL but with a format and price point more accessible to users who don’t require the real-time frequency and impulse response mode analysis capabilities of our flagship Smaart v8 software.

Important: For accurate SPL measurements, this product requires the use of microphone calibrator in addition to a suitable acoustic test & measurement microphone and a microphone preamp / audio interface.

NOTE:  Once a Smaart license has been registered to a license management account at and activated on any computer, it is non-returnable and non-refundable.  We encourage you to take advantage of the free 30-day demo for all Smaart software products prior to purchase, to ensure it meets your requirements.
