"WaveForming delivers a solution to the most challenging aspect of home cinema: eliminating the effect of room modes that makes accurate low-frequency reproduction difficult if not impossible," Trinnov states. The product of more than 6 years of Trinnov research, WaveForming combines a new algorithm and new home theater design guidelines to effectively reduce low-frequency problems inherent to small rooms: the muddy sound produced by long reverberation times and the large variation heard among multiple seats.
First demonstrated as a concept at ISE 2023, and officially announced as WaveForming in May 2023, the technology is part of the company's vision for room acoustics, utilizing passive and active elements. This includes using the loudspeaker and subwoofer arrays in the room to help control and "steer" bass reflections.
"We are truly excited to be able to present the astonishing improvements of Waveforming to the industry at CEDIA Expo," says Trinnov Audio CEO and co-founder Arnaud Laborie. "Our new technology can elevate the performance of home cinemas to a previously unobtainable level. The challenge of accurate reproduction of low frequencies in small rooms has historically been addressed with band-aid approaches that do not resolve the underlying physical problems. WaveForming takes a fundamental approach that effectively eliminates the standing waves that are the persistent challenge."
WaveForming at CEDIA Expo
WaveForming requires the use of multiple subwoofers on both the front and back walls of the room. The specific locations are determined by the room dimensions and the desired bandwidth coverage. As with any system, a higher number of subwoofers can generally give better performance, but WaveForming offers wide flexibility in terms of the number and placement of subwoofers.
Trinnov’s CEDIA 13.1.6 Dolby Atmos demonstration system incorporates multiple 21-inch Ascendo subwoofers to enable demonstrations of WaveForming's performance when using widely varying subwoofer configurations. Trinnov WaveForming demonstrations will showcase a 3x2 configuration, consisting of three subwoofers in the front wall and two subwoofers in the back wall. This demonstrates the effectiveness of WaveForming with a relatively modest number of subwoofers and room modifications necessary for its implementation.
Also demonstrated will be a 12x2 configuration, with 12 subwoofers in the front wall and just 2 in the back wall, demonstrating that the front and back subwoofer arrays in WaveForming do not have to be identical and that even with a much smaller number of subwoofers located in the back wall, WaveForming is still effective.
A final presentation will use a double bass array consisting of 12 subwoofers in the front wall and 12 subwoofers in the back wall. This shows WaveForming in its fully realized and uncompromised configuration. The demonstration content for this presentation uses the entire array of subwoofers, enabling listeners to experience the infrasonic capabilities of Ascendo subwoofers.
Separate from the Trinnov demonstration, attendees will also be able to experience WaveForming in the Alcons Audio demo system in CEDIA Sound Room 9. All demonstrations will use Trinnov Audio's Altitude32 reference processor and an Altitude48EXT, which expands the system’s capability to 48 channels, powered by Trinnov's Amplitude16 amplifier.
On Thursday, between 9 and 11am in Mile High Ballroom C, Trinnov CEO and co-founder Arnaud Laborie will present a lecture titled Next Generation Bass, explaining how WaveForming addresses room modes and resolves the most challenging acoustical issues.
The CEDIA 2023 demonstration uses Ascendo's active systems, including infrasonic subwoofers and coaxial point source loudspeakers on all channels. Kaleidescape’s Terra movie server and Strato-C movie player will deliver the content, while madVR Labs' all-new Envy Extreme MK2 video processor will deliver best-in-class dynamic HDR tone mapping, along with the debut of its groundbreaking MotionAI motion interpolation processor. Images will be projected using a 9,000 lumen 4K Barco Njord CS laser projector in a Seymour-Screen acoustically transparent screen material. The room will be designed and built by Italian company Officina Acustica using its modular fully custom system, handcrafted in Italy, and built at the show in three days. Cables for the demo system are provided by Kordz, and the control system is provided by RTI.
