Description

deciBel is the result of a serious effort to make an Android based SPL meter as close to a professional-grade device as the phone hardware limitations allow.

It uses a Fast Fourier Transform algorithm to implement a high precision A weighting filter and sophisticated digital signal processing techniques to achieve the best possible SPL readings out of your Android phone or tablet.

It displays the current, maximum and minimum values in decibels, and generates 3 kinds of sound pressure level versus time charts. The display can be turned upside down to allow pointing the mic at the sound source.

deciBel is supported by ads.

### Please calibrate before the first use! ###
