It is simple and works – Decibel X PRO: dBA Noise Meter Review

I got this ap because the screen shot shows sound pressure levels on an octave chart and a historical graph. I wanted to record this spectrum, or at least capture averages for each octave, but it turns out it only plots the average. It does show instantaneous octave bands.
