BSR Quality is a software released from BSRTools series, designed to measure and represent the variables related to quality of sound. it offers a real-time window demonstrating SPL, Leq, Loudness & N10 level on the scream in real-time for the data measured through either DAQ and microphone or PC soundcard, and recording option. The recorded data can be viewed in data viewer window for further analysis on comparing Leq and N10 Loudness for two arbitrary selected time zone. BSRTools is a set of different software and hardware tools, each focusing on measuring, evaluating, and identifying various aspects of Buzz, Squeak, and Rattle.
