What is Room Correction and Speaker Optimization?

The acoustics of a room affects the sound that you hear coming from your speakers which in turn affects the way you manipulate your mix.  Traditional methods of acoustic treatment will help to control this but there are still artefacts that cannot be corrected by acoustics alone. Trinnov Audio has developed a range of stereo and surround optimisers using the latest DSP real-time processing that will improve the accuracy of your room through your speaker system.

Trinnov has applied the results of breakthrough research in loudspeaker/room acoustics to create a new generation of loudspeaker processors, setting a new benchmark for accurate sound reproduction. The Trinnov Optimizer takes mix translation to the next level.

While the room and the loudspeakers need to be analysed and eventually treated separately by most technologies on the market, the Optimizer considers and addresses every aspect of the reproduction system in its acoustic environment at the same time. Problems are identified, cross-analysed and compensated with the most efficient and best-sounding compromise. 

Trinnov 3D Mic Design

The measurement microphone is one of the most critical components of any loudspeaker/room calibration system.

Trinnov’s sophisticated algorithms rely not only on extremely accurate acoustic measurements but also on the ability to localize the speakers’ positions and to detect early reflections.

The Trinnov 3D Mic uses four mic elements in a precise tetrahedral arrangement. Each capsule is individually calibrated at the factory (±0.1 dB from 20 Hz to 24 kHz) The resulting microphone calibration file is included in the microphone’s box on a USB stick.

Optimization Process

As each speaker is measured, the resulting sound waves pass through this array of microphones, hitting each one at a slightly different time. Based on this timing, we can triangulate the location of the speaker from which the sound arrived. By testing each speaker in turn, we build a three-dimensional map of where the speakers are relative to the mic (which is placed at the main listening position).

This is measured to within 2° of azimuth, 2° of elevation, and 1 cm of distance. This information enables the proprietary Remapping technology, which is translated from the theoretical rendering of the soundtrack to the specifics of your particular room. Remapping uses the two or three speakers closest to the intended location of a sound to create a phantom image of the sound coming from the correct direction.
