Real Sound Lab’s Demo CONEQ EQ. Irvine, CA (August 31, 2007)–Real Sound Lab PRO LLC, the U.S. sales and marketing arm of Latvia-based Real Sound Lab, will provide hourly demonstrations of its CONEQ Measurement Technology during the 123rd Audio Engineering Society Convention, to be held October 5-8 at the Jacob K. Javits Convention Center in New York.
According to Real Sound Lab, CONEQ Measurement Technology offers automated EQ using acoustic power frequency response and reportedly enables inverse FIR filter corrections to be applied with repeatable success. CONEQ can be seen in Demo Room 3D07, and at Booth 669. At the end of each demo session, a jazz trio will perform through a CONEQ corrected-loudspeaker system, jumping in and out of a pre-recorded track, the intention being to demonstrate that a loudspeaker corrected with CONEQ is “virtually indistinguishable” from the sound of live instruments.
“CONEQ lets a system engineer take a true acoustic power measurement of a loudspeaker or loudspeaker array,” says Ken DeLoria, director of Real Sound Lab’s Pro Audio Division. “Unlike SPL measurements, acoustic power can best be characterized as the complex conjugate of several hundred measurement points taken around the sound emitter. If that sounds like a mouthful, just think of CONEQ as covering all the intersections of a finely spaced ‘grid’ in front of the speaker system.”
Following the measurement process, which takes about two minutes, CONEQ synthesizes a 4,096-point inverse filter that precisely corrects the loudspeaker’s frequency response to a flat target response or, to a specific, “personality profile” that can be anything the user requires. “The resultant sonic quality is nothing short of astounding,” says DeLoria.
CONEQ was invented by Raimonds Skuruls, a Latvian mathematician and Real Sound Lab co-founder who has been studying acoustic power measurement and its applicability to reproduced sound since the 1980s. CONEQ introduces a negligible latency: less than 2 mS with analog I/O.
“A CONEQ-corrected loudspeaker is hard to distinguish from the original sound source,” DeLoria asserts. “While CONEQ makes a good loudspeaker system sound far, far better, it makes a great loudspeaker system sound even better still! CONEQ is particularly useful in improving translation. Material mixed on one set of speakers must sound the same on many other types and brands; CONEQ plays a strong role in leveling the playing field.”
Real Sound Lab states that CONEQ technology is applicable to touring, AV presentation, installed sound, music recording, film and video post production, broadcast and cinematic exhibition. CONEQ is available as a hardware and software solution. The company is actively seeking technology licensees, distribution partners and dealers.
