About PAcalculate
Over 25 calculators for pro-audio sound reinforcement and lighting, as well as reference info and utilities. A super handy tool for people dealing with PA, sound reinforcement, sound systems, electroacoustics, pro-audio and lighting
- SPL (sound pressure level). Enter sensitivity in dB SPL, power, number of loudspeakers, phase and distance
- SPL sum
- Air absorption attenuation for a given humidity, temperature, frequency and distance
- Ceiling speaker coverage
- Time «» Distance
- Audio frequency «» Wavelength (includes lambda/2 and 2*lambda/3 for line arrays or subwoofer arrays)
- dBu «» dBV «» Volts
- Q «» B/W (bandwidth)
- Limiter threshold
- Amplifier gain
- Speaker cable: low impedance, high impedance (constant voltage line, 70V/100V). Calculates energy and level loss, system damping factor
- Electrical and musical calculators that are related to audio. Unit conversion
- Lights: DMX channel, RGB/RGBW/RGBA and CMY
- Reference info:
Pinouts, proaudio (XLR, 1/4", SpeakOn, DB25) and lighting (XLR3, XLR5) and graphs (Fletcher&Munson, microphone polar plots)
- Utilities (inclinometer, flashlight-needs camera permission)

This app says it needs access to my camera. Why? Tried to contact the developer via "Feedback", but there seems to be a problem with his email verification system that proves I am not a robot. I followed the instructions, but it just sent another verification email.

All very good having all the calculators. Very useful. But, the interface is just too slow to use in a gig situation. All those fancy fades and transitions are unnecessary and distracting. Just take me to the page I want. Also, who puts an intro on a calculator app? Just wastes time and is annoying.

At last an app for android that does a range of audio calculations. Does what it says on the tin!

A really useful 5-star audio toolkit, but spoiled by the interface - unlike the website version you have to go through 6 screens before you get to the calculators - similar apps like ElectroDroid take you to the calculator you want with a single touch.

So many useful tools here. Pretty much any conversion you would ever need to do, this will now do the heavy lifting.
