How accurate is this meter compared to other professional SPL meters?
Analyzing from microphone will not give you accurate SPL-Loudness values since it is limited to the hardware on which is being used. If you want to know exact SPL-Loudness level please use professional hardware made for that use. However, if you want to compare perceived loudness of two different sounds this meter will do a great job.
Analyzing from file will give you accurate results comparable to results from other professional analyzers.
