Description

26 calculators (43 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). 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)
- Transition distance for line arrays (near to far field)
- End-fire array

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

Reference info such as pinouts (proaudio and lighting) and graphs

Muy buena y util

Solo agregaría un botón volver a la app cuando se consulta el foro desde ella...

Gran App

Es de agradecer para los que trabajamos en el campo de audio y iluminación gran aporte. Es super fácil de usar y de gran utilidad. Gracias ¡¡¡
