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 lightingThe app is very light (~1MB, like a typical mobile phone photo), works offline and uses no data bandwidthMore 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)iOS (iPhone/iPad) version also available
