Trinnov Audio started research on Loudspeaker/Room optimization in 2003 and released its first multichannel processor featuring its Optimizer technology in 2005.
The Optimizer was primarily intended for studios. Trinnov built its reputation with this technology while winning the trust of some of the most demanding sound engineers in broadcast, music, and post-production studios around the world. The Optimizer has been gradually refined over the years and is now the only “digital room correction” system widely used throughout the production chain, from studios to some of the finest commercial and private cinemas. It is used daily in over 1500 studios worldwide to produce some of the content you enjoy every day.

The Optimizer is also used in over 1500 commercial theaters. Here is the 800-seat UGC Normandie, Champs-Elysées, Paris.
Unique in many ways, the Optimizer relies on Trinnov’s iconic 3D Microphone to localize speakers and capture sound in three dimensions. This microphone is designed by and unique to Trinnov, and each one is individually calibrated for accuracy to ensure the most reliable acoustic measurement. Indeed, because Trinnov feels nothing should be left to chance, they keep the entire signal path within a Trinnov-controlled environment (in their processor) rather than relying on external software, operating systems and audio interfaces.

The Optimizer captures a huge amount of acoustic information in each measurement and performs time/frequency analysis to better understand and characterize the behavior of the speakers in the room. (Indeed, without the time domain, frequency response alone shows irregularities in response but doesn’t provide enough information to correct the errors properly, with the appropriate method.)

The highly-detailed information is then processed using Trinnov’s proprietary algorithms, providing a full acoustic analysis of the room and revealing more information than any other automatic system. As an example, the acoustic graphs generated by the Optimizer for each measurement point include the phase response, group delay, and impulse response of each speaker, all of which are important to understand what is occurring in the room over time.
Most people understand that time-aligning speakers is important; but the point Trinnov has made since 2005 is that time-aligning frequencies is also essential for improving sound staging and transient reproduction. This is an area where passive acoustic treatment, although extremely important, cannot help.
The sophistication of acoustic analysis performed by the Optimizer may sound like overkill for the consumer world. However, Trinnov is understandably proud of its pro audio background and believes consumers deserve no less. The Optimizer simply can solve problems that other systems cannot, and this is an area where Trinnov reigns supreme. Fortunately, Trinnov introduced a setup wizard to simplify the initial measurement and calibration process.
Trinnov introduced a step-by-step calibration assistant to simplify the whole process.

However, the manufacturer remains clear about the fact that every system is unique. Many acoustic parameters come into play, whether they are related to room acoustics, electro acoustics or psycho acoustics. The best possible results can only be achieved by a trained ear and experienced calibrator. This fact is not specific to Trinnov but is true for any system, regardless of its sophistication.
Trinnov really shines with respect to the level of integration of the Optimizer within their products. The Optimizer doesn’t require external equipment beyond the microphone. It takes only a few clicks to make the system sing, whether you do it locally or remotely over the internet. Since the measurement data resides in the machine itself, subsequent tweaks are easily made, all with 64-bit floating point precision.
All Trinnov products include the Optimizer technology, including the Altitude AV Processor range.
