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.

Live Audio Multi-Tool (LAM-T) is a fast, offline toolbox for live sound engineers, system techs, AV installers, and musicians. Everything you reach for at a gig — an analyzer, an SPL meter, a delay calculator, sub-array alignment, a signal generator — in one clean app. No account, no ads, no tracking. REAL-TIME ANALYZER (RTA) • Fractional-octave RTA with a live peak readout • A / C / Z weighting • Spectrogram view, freeze, peak hold, and capture/compare • Adjustable Y-offset for quick reference matching • Spectrogram sensitivity control to bring out quiet detail SPL METER + Leq • dB(A), dB(C), dB(Z) with peak hold • Running Leq over 1, 15, or 60 minutes • Per-device calibration offset — match it to a real meter once and it sticks DELAY CALCULATOR • Speed-of-sound delay from real temperature and humidity (auto-filled from your location) • Feet or metres SUB-ARRAY DESIGNER • Broadside and end-fire arrays • Cardioid tops (castellated or all-subs) • Per-sub delay times computed for your spacing and coverage SIGNAL GENERATOR • Sine (20 Hz–20 kHz, log sweep), pink noise, and a polarity-check pulse • Polarity reader — check a speaker's polarity through the mic UNIT CONVERTERS • Temperature, distance, and pressure • Reads your device's barometer for true local air pressure Built for the real world: it works offline, launches instantly, and stays out of your way. Informational only, no warranty. Measurements and conversions are estimates — verify anything critical with calibrated instruments.
