THE APP Introducing On-Axis: The must-have app for audio professionals in the event and touring industry! Measure and model your audience area with a completely new method compatible with many popular loudspeaker simulation programs. The On-Axis method significantly speeds up the measurement of the audience area, allowing you to focus on the most important thing, making the actual speaker design. WORKFLOW The On-Axis workflow begins by taking measurements of the audience area with the app. The On-Axis exports a file that can be imported into the selected loudspeaker simulation software. The On-Axis does not replace traditional methods such as CAD drawings or other precise models. It is a new addition to your existing toolbox. MODES The app consists of three different operating modes. Venue and Planes mode can be used to draw a 3D model of the listening area. The On-Axis Profile mode can be used to draw a uniform plane to the speaker’s axis, starting from the speaker’s rigging point and ending at the farthest point of the audience area. BLUETOOTH SUPPORT The app can be paired with a compatible laser distance finder via Bluetooth. This enables the measured distance and angle to be transferred wirelessly. See the compatibility chart for more info on supported devices. TO GET STARTED Watch the tutorial videos to get started: http://link.oksound.fi/playlist The app is free to download but requires an In-App-Purchase to unlock the export, save and open functions. A 14-day free full trial is also available to see if this tool fits your workflow.  This is a 3rd party solution and compatibility with simulation software is guaranteed only with tested versions.

d&b Tonio takes the functionality of QR codes to the next level. Is the fastest tool to transmit weblinks to a device in the world of audio and video. It picks up sounds you can‘t hear, but your device uses them to show you information and turn listening and watching a show into a truly immersive experience. Imagine you‘re at a concert of your favourite band. They are introducing a new song. You‘ll get the lyrics of the song directly on your smartphone and the right time and can immediately sing along. Or your favourite singer talks about what inspired him or her to write the song – and you receive photos that have never been shared with the media directly on your phone. Wouldn‘t that be amazing? And it doesn‘t stop there. When it’s crowded, getting announcements straight to your phone can be a life-saver (or maybe you‘ll just not miss the train, which of course could make all the difference). And people hearing impairments, can receive valuable information and be part of the same experience. And now it’s time: download the app, let the app listen and get all the information you need!
