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) Latest news from DoctorProAudio.com
