【實用工具app】PAcalculate|最夯免費app-綠色工廠好玩App

Over 22 calculators 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- 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)- dBu «» dBV «» Volts- Q «» B/W (bandwidth)- Limiter threshold- Amplifier gain- 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- Utilities
