Full description
** App is not working correctly on android version lower than 5.0 (Lollipop). Keep that in mind please! ** * If you've used this app to build a diffuser, please send me a picture in email [[email protected]] * This app is the most handy tool for building an acoustic diffuser. You are able to save thousands of dollars on acoustic treatment using this app. It's user friendly and everything is well explained (if you click the "?" icon at the top, there is an explanation for everything that was on the screen before you clicked the icon). You are able to build Skyline, QRD or 2D QRD diffuser. The app calculates the frequency range, minimum seating distance, dimensions, well / prism width and every single piece of wood that you need to build your diffuser. There is a help tool for cutting the wood. It tells you what is the sequence number of the wood that you are actualy working at, its length, how many of them are needed and how many of them are already cut. There's also a help tool for building the diffuser. It tells you exactly which (and what length) wooden prism to place for the actual row and column that you are at. If it's done and that prism is placed, you just click the right arrow and you are ready to place another one! You are able to save your diffuser while building one, so the app itself remembers the specifications, how many wooden prisms are already cut and the exact position where you left your diffuser build. You don't need to worry about anything! This is the perfect app for you if you want to build diffusers. Even if there are PC apps for diffuser calculation, this one gives you a lot more flexibility and more precise diffuser calculation! Design your own acoustic diffuser for the frequency range that you need, the size that you want and the pattern design that you would like it to be!
