PAcalculate

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)
