PAcalculate

28 calculators (47 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, electro-acoustics, pro-audio and lighting

Acoustics

• SPL (sound pressure level)
• SPL sum with phase, distance or time difference
• 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)
• Transition distance for line arrays (near to far field)
• End-fire and broadside array subwoofer modelling

Audio electronics

• dBu «» dBV «» Volts
• Q «» B/W (bandwidth)
• Limiter threshold, attack&releases times
• Amplifier gain

Cabling

• Speaker cable: low impedance, high impedance (constant voltage line, 70V/100V). Calculates energy and level loss, system damping factor

Lights DMX channel, RGB/RGBW/RGBA and CMY

Useful reference info such as pinouts (proaudio and lighting) and graphs

Utilities: Inclinometer, Flashlight / light with selectable intermittence (uses camera permission)
