PAcalculate vs Impulso

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

Impulso Lite allows you to measure the acoustic response of your room using your iPhone. You can visualize the measured reverberation time (RT) in octave bands and then simulate how the acoustic response of your room will be improved when adding artnovion acoustic products. You can enter room dimensions and select the type of room you are designing for. The app will then tell if your room meets the expected RT and you can select products to optimize the response accordingly. Impulso Lite allows you to take a measurement with an internally generated signal if you are able to play it via a loudspeaker system, or using an external impulse source, such as a balloon, if you don’t. Compatible with built-in or external microphones. Check out Impulso Pro for detailed plots of energy time curves, to check for undesirable reflections, a frequency plot, which you can zoom in and a table with the acoustic parameters of your measurements such as C80, D50, STI and Bass Ratio. Impulso Pro also adds tramlines to the RT plot so you can fully optimize the response to meet the criteria for the room type selected. You can also display the spectral response of the microphone input using the new Real Time Analyzer. Check more at www.artnovion.com
