Description
27 calculators (44 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 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
Reference info such as pinouts (proaudio and lighting) and graphs
Utilities
What’s New
Version 1.3.2
- Broadside (line) array modelling with electronic or mechanical arcing and steering as well as end-fire/gradient(cardioid) lines
- Array modelling is now more insightful: provides a left/right mirror image option and 3 new graphics (isobar display, coverage map and multi-angle frequency responses) as well as a horizontal viewing mode that packs more information on the screen
- Easier introduction of values below 1 in Q «» BW calculator
- Fixed main menu link to news and educational content
- Additional support for larger system fonts
