Trinnov's sophisticated algorithms not only rely on very accurate acoustic measurements but also on the ability to localize speakers positions and to detect early reflection provenance. Trinnov's 3D measurement microphone is the result of our extensive research in 3D sound. We invested a significant amount of time to design a tailored measurement system that could gather very precise information regarding the spatial position of multiple sources. This is called triangulation. Each of the four omnidirectional capsules is placed at the same distance from each other, forming a tetrahedral pattern. This allows us to localize each speaker's placement on both horizontal and vertical planes. -To achieve this challenge, the microphone consists of 4 capsules mounted at the top of thin brass tubes to avoid diffraction. -The capsules form a tetrahedron figure, ideal for identifying distance, azimuth, and elevation altogether. -To optimize spatial accuracy, all the capsules responses are analyzed and compared recursively to find the best possible matches of 4 and reach a spatial resolution below +/-2 in every direction. -Supplied with cable and suspension/holder.
