2D/3D loudspeaker remapping opens new perspectives in high performance immersive sound, ensuring a unique experience by putting the listener right in the middle of the action, in an incredibly realistic, life-like and holographic multidimensional soundscape.

The 2D/3D loudspeaker remapping technology developed by Trinnov Audio is protected by an international patent. Thanks to the microphone 3D measurements capabilities, speakers original placement can precisely be localized in the room, in terms of distance, azimuth and elevation. According to these reported informations, a more accurate speaker placement can be retrieved.

While 2D remapping deals mainly with the horizontal plane, 3D remapping will manage both azimuths and elevations. As an example, a central speaker placed below or above a video screen can be virtually repositionned in the same plane as the left and right speakers. This is particularly useful in small rooms and OB Vans, where the lack of space doesn’t always allow for ideal speaker placement.

2D and 3D remapping is a perfect solution for ensuring a full compliance to broadcast, music and cinema sound reproduction standards, regardless of the constraints of your room.
The remapping technology relies on Trinnov’s unique 3D measurement microphone that localizes the speakers in the room to retrieve a multidimensional loudspeaker mapping of the room within +/-2° accuracy.

A 3D spatial remapping matrix is computed from the speakers coordinates and applied to the input signals in real time to virtually compensate for inaccurate speaker placement according to the content’s format. It guarantees optimum spatial resolution and faithful tridimensional sound staging. In other words, the remapping process automatically distributes the signals, providing a solution to drive speakers in the optimal manner to recover the original 3D sound stage, as intended by the artist.

In fact, the loudspeaker remapping satisfies many functional requirements:

  1. Formats Interoperability: the remapping is the only solution to format war, as it ensures inter compatibility between existing and future 3D audio standards, with an optimal use of speakers and the best possible spatial resolution.
  2. Formats Scalability: If the number of inputs is different from the number of outputs, one could describe the remapping technology as a universal up/down scaling algorithm for faithful 3D audio reproduction.
  3. Architectural constraints: even with format-specific speaker layouts ranging from 5.1 to any possible 3D format, the remapping will compensate for inaccurate speaker placement imposed by typical room shapes and provide a dramatic improvement in the reproduction of the sound stage.
