Description
Over 42 calculations 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
The app is very light (like a typical mobile phone photo), works offline and uses no data bandwidth
More than 42 calculations spread across 26 calculators: - 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) - Line Array transition distance (near field to far field) - In-line (end-fire, gradient) array simulation with left/right mirroring - Broadside (line) subwoofer array modelling with electronic or mechanical arcing and steering as well as end-fire/gradient(cardioid) lines - dBu «» dBV «» Volts - Q «» B/W (bandwidth) - Limiter threshold (and times) - 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", 1/8", SpeakOn, DB25) and lighting (XLR3, XLR5) and graphs (Fletcher&Munson, microphone polar plots) - Utilities (inclinometer, flashlight-needs camera permission that can be later revoked in phone settings) - Link to latest industry news and educational content from DoctorProAudio.com
iOS (iPhone/iPad) version also available
Recent changes: - SPL sum calculator now allows summing with phase distance or time difference - The flashlight / light can now flash at two speeds for signalling use - Improved appearance in dark mode - Fixes fields with occasional flashing background

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

So many useful tools here. Pretty much any conversion you would ever need to do, this will now do the heavy lifting.
★★★★☆A Google User· Feb 10, 2014
Great app, but...... 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.

Thanks for nice App to calculate DJ Equipment's Question: While calculate Limiter threshold, Power input is in RMS power or any other power ?

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.

Awful, it is super laggy and has ads every 5 seconds
