VideoCalc vs NoiseLab

VideoCalc is The tool that will help you design Home Theaters in a consistent, quick and easy way. It makes all the tedious calculations a breeze and ensures you can get the desired information in an intuitive way. This is a must have for Home Theater enthusiasts, custom installers, video professionals and more. VideoCalc is made up of several tools, that each in its own right provide you with essential calculations but do work together, ensuring the effect of every component on the system is taken into account. Furthermore the tools are organized in a natural progression, guiding you through the process of designing a Home Theater that follows the industry best practices and standards. Start by defining your screen. The tool allows easy calculation of any screen dimension based on the others. Support for usual aspect ratios is provided, allowing you to pick amongst a selection of the most commonly used aspects. For a projection system, the next step tackles the projector part, defining the aspect ratio of the matrix and the optional usage of an anamorphic lens. The tool shows you how the image will fit within the defined screen and the deformation that the anamorphic lens would apply to the projected image. This is also a fantastic tutorial tool to understand anamorphic systems. The next step takes care of projector placement and/or selection in regards to the throw ratio requirements. Enter the throw ratio range of your projector and check it can be placed to work with your screen. Alternatively, enter the distance from the screen where you wish to place your projector and the tool computes the required throw ratio. This is perfect for selecting your lens on higher-end projectors. The Luminance tab allows to find out how big the screen can be with a given projector or how bright your projector must be to light up the defined screen, while respecting the industry best practices. With the Angle tab, validate that your field of view is in accordance with industry accepted standards such as THX or SMPTE. VideoCalc works in both imperial and metric units. Simply swipe down to reveal the unit selection view, giving you the choice between centimeters, meters, inches and feet. If you like this tool, be sure to also check AudioCalc, the companion tool addressing your audio needs.

NoiseLab is a professional noise meter APP developed by ZKXY (member of BSWA Group). It turns your iOS device into a professional acoustical analysis meter, precisely measures the sound pressure level and the frequency characteristic around you. For acoustic engineers to comply with IEC and ASTM standards, it is essential to use external soundcard and microphones. MicW i437 microphone is recommended to use in high-precision measurement, and i437 can be purchased in Amazon and other web-shops online. HIGHLIGHTS: - Support the built-in Microphone and the external microphone, the latter has 3 gains to choose. - Measurements of any combinations of Filter Z, A, B, C and Time detector Fast, Slow and Impulse simultaneously. 3 profiles results can be shown simultaneously - The system can be calibrated by using sound calibrators with 94 dB and 114 dB at 1000 Hz, or manual input of calibration factor. - Measured time history of sound pressure level can be saved into the list of history report and easily export to computer and send by email. - Calculate and show the Current and integral Octave analysis results - Octave result can be saved, and max 3 previous Octave results can be shown to compare. About BSWA Group: Established in 1998, BSWA Group has twenty years of experiences in developing and manufacturing acoustical measurement instruments. BSWA’s products are distributed in over 40 countries through sales partners, covering the businesses of: - Manufacturing the world class measurement microphones - Developing acoustic measurement systems and devices - Designing and building anechoic chambers - Acoustical consulting for environmental and noise control projects.
