SPL Spectrum Analyzer PRO measures and analyses sound pressure level (SPL) and sound frequency spectrum in real time (RTA) using FFT. It is accurate and very fast with refresh rate more than 10 Hz.
RTA analyzer can work on 2 separate channels. User can later compare SPL and frequency response charts between the channels. User can also enable "peak hold" function. Flat reference line is also shown to help you equalize the spectrum.
Microphone can be accurately calibrated under settings for each frequency band separately. This is the PRO version without ads!
