Description

deciBel Pro is the result of a serious effortto make an Android based SPL meter as close to a professional-gradedevice as the phone hardware limitations allow.

It uses a Fast Fourier Transform algorithm to implement highprecision A, B, C and Z weighting filters and sophisticated digitalsignal processing techniques to achieve the best possible SPLreadings 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 atthe sound source.

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

Features:

- true A, B, C and Z Weighting (ANSI S1.4)
- numeric dB, dBmin and dBmax display
- simple calibration interface
- Automatic Calibration function (no professional SPL meterrequired for reasonable startup accuracy)
- sliding sound level versus time chart
- sliding max, min and average soud level versus time chart
- accumulated sound level exposition chart (dosimeter)
- saves chart screenshots 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

Sidereal Clock 1.8.3 APK
BSB Mobile
The Sidereal Clock displays sidereal times andseveral other time standards, such as UTC, solar time and juliandate. It has 3 time displays and you can choose what time to showin each of them.All the displayed times are computed from the Sidereal Clock's owntimebase which is synchronized to an external high precision NTPtime server.To compute the local times it gets your longitude via GPS.The Sidereal Clock is supported by ads.
