PAcalculate: Offline pro-audio and lighting calculators for mobile phones and tablets

PAcalculate calculator iOS IconBrusi Acoustics, a consulting firm based in Valencia (Spain), has announced the availability of PAcalculate, a free multi-lingual multi-platform mobile app with calculators and other information and utilities for pro-audio and lighting professionals. PAcalculate can be installed on iOS (Apple), Android, Windows-Phone 8 and Blackberry devices from their respective app stores. The application uses responsive design developed to work on screens that range from a classic Blackberry to a large tablet. Both metric and English units are supported.

PA related calculators include SPL, SPL addition, ceiling speaker coverage, air absorption, time to distance (and vice versa), frequency to wavelength (and vice versa) with full and half lambda options for arrays, Q factor to bandwidth conversion, dBu-dBV-Volts and speaker cable losses (low and high impedance). For lighting, a DMX calculator as well and RGBW and CMY LED emulations are provided. Calculators provide comprehensive options as well as built-in help. Other calculators are not directly related to the industry, but will nonetheless be useful: Ohm’s / Joule’s Law, KVA, BPM to time and conversion of weighs and measures.

In addition to calculators, pin assignment information is provided for some of the most common audio and lighting connectors. Lastly, an inclinometer utility rounds up the feature set.

At the time of writing this, PAcalculate came with English, Spanish, Portuguese and Simplified Chinese language sets. The developers are seeking collaborative translations to other major languages; translators will be listed on the credits. They estimate the app, which can be used without an Internet connection, will be installable in 94% of smart phones.

“We tried to pack an extensive bunch of tools that could be useful for sound reinforcement professionals doing live or fixed install work, plus some lighting ones too. While there is no rocket science involved in the calculations, some can get cumbersome, specially in the field, and others can get very complicated very easily (such as calculating time delays taking into account the effect of temperature, which can be critical for delay synchronization). Others, like KVA calculations or unit conversions are not specific to our industry, but will nevertheless be useful to have under the same roof, without the need to exit the application. We’ll be listening carefully in the future and adding new tools and contents based on users’ feedback”, comments Senior Consultant José Brusi.

Rainbow, electro-acoustical prediction software from VMB

Cardioid designValencia, Spain, August 2009 – VMB is pleased to announce the availability of Rainbow, its electro-acoustical prediction software for the company’s speaker systems, boasting horizontal as well as vertical modelling.

Windows-based, Rainbow allows simulation of complete systems, such as a main large format array complemented by a smaller delayed array and front-fills. Thus, its library of loudspeaker systems includes, not only the company’s self-powered line array modules with built-in inclinometer (LX-V8 and LX-F6 with accordion-folded ribbon HF driver), but also models from its PHASE or ADP lines.

Jesús Fuentes, National Sales Director, comments: “Customers need to model a complete system. Generic software is OK if only a single array is used. In practice, however, fill systems are usually required. One must also examine what’s happening in the horizontal plane, not just vertically. So the only way to provide a more

VMB ARKEOPS: Digital controllers with air absorption compensation

Valencia, Spain, December 2008 – Version 3 of VMB’s ARKEOPS digital controllers boasts air absorption compensation.

ARKEOPS ARK-48The attenuation effects of air are well known. At 15 000Hz, for instance, 12 dB of loss can be observed at 30 metres (100 feet) with 30% relative humidity. This makes an otherwise flat frequency response at close range totally dull when the audience is located at a distance. The problem gets worse as humidity decreases and to a less extent when it gets colder. more
