Comments from your perspective:
Thanks for the opportunity to participate in the Audioholics survey. We audio enthusiasts are indeed at the cusp of a revolutionary period for reproduction made possible by new acoustical research and affordable DSP processing power. Everyone has been looking for the next big improvement in sound. This is hinted to be a combination of room tuning and DSP software based acoustical solutions. We know room tuning can help- but how much? We know DSP acoustical solutions promise to help, but when will they be really useful? When should we adopt them? What will be the most useful balance between the two?
So we have Jeff Hedback’s “20 questions…” For us at Trinnov, our perspective comes from years of ongoing 3d audio research (we are audio enthusiasts with advanced acoustical and DSP degrees, and access to top acoustical labs). The answer lies in changing the game in one unique and profound way: considering audio processing in the context of 3d acoustic fields. To get it right in our listening environments we’ll have to fulfill three conditions- (1) get all loudspeakers to voice the same, (2) exactly duplicate the placement used in the studio where the mix was done, and (3) do it with detail intact. With those three things done we'll find the golden rainbow of audio.
Spatiality: the loudspeaker- "spatiality of the loudspeaker response" is a way of defining a loudspeaker's ability to provide uniform coverage over a listening area, and is a factor in the" sweet spot size." Trinnov views this as part of voicing or compensation.
Spatiality: the acoustic image- in the scientific context, spatiality is considered to be the "localization of sound sources," and Trinnov addresses this uniquely as a separate opportunity to improve the listening experience. Trinnov offers an advanced, patented solution for improving spatiality by actually remapping the speaker signals to precisely match their placement relative to the listener.
On the DSP side of integrating the speaker and room acoustic into a unified system, Trinnov offers an audio "Optimizer" toolkit that has four parts: (1) a calibration system that is smart enough to figure out all kinds of acoustical phenomena with respect to your loudspeakers and your listening room. The system accurately identifies in 3d where the loudspeakers are. (2) The Optimizer takes the 3d data from your “speaker/room” system, does an in depth analysis for solving the voicing/ spatiality equation, (3) processes the audio with appropriate correction and reproduces with transparent results, and (4) reports the before and after results of amplitude, phase, impulse responses, and speaker position. The report is then useful in determining what acoustical treatment might be suitable. The Optimizer puts the listener way ahead of where you were to begin with, and you know exactly where you stood with your system. Maybe the extra room treatment would help even more, but maybe not to the degree to be worth the effort. You decide.
So, to summarize: We’ve responded to the survey with one condition in mind: the Trinnov Optimizer is a part of the system. Trinnov has come up with a remarkable solution for audiophile reproduction: consistent voicing and spatiality. The result is truly liberating: (1) place speakers where you can, (2) use Optimizer to overcome the shortcomings of both loudspeaker placement and the room/speaker system. The Optimizer is a stand alone unit manufactured by Trinnov, and will soon be in selected surround processors.
