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! ###
Features:
- true A-Weighting (ANSI S1.4)
- simple calibration interface
- numeric dB, dBmin and dBmax display
- sliding sound level versus time chart
- sliding max, min and average soud level versus time chart
- accumulated sound level exposition chart (dosimeter)
- saves chart screen shots to the SD card
- dominant frequency display
- 22Khz bandwidth at the input of the weighting filter
- 1024 point real time FFT and digital sound processing
- movable to the SD card

Awesome app! I calibrated this at work and for a phone it does well! Will do! for non critical applications!

Limited by phone's mic capabilities I have noisy neighbors and wanted a scientific threshold to measure them by. Unfortunately, my phone's mic doesn't pick up sounds that aren't in the immediate proximity of the phone.

Excellent app This is an awesome app! Im into sound and the fact that u can calibrate is top! I havent used it fully yet but i will try it. Few things i would like to see in updates would be maybe an average function where we could set it to say 1 min and it will calculatr the average over that time set. Maybe also a log where u can save highest readings? Thanks for the great app

Suits my purpose! Nice charting, and screen save option is great, (especially if you want proof) ‡•)
