Audioscenic implements BeClear technology for world’s first Hi-D soundbar design with gaming voice chat

Audioscenic has announced a technology collaboration with Philips and NXP Semiconductors, to provide the world’s first reference design for gaming soundbars, combining Audioscenic Amphi Hi-D spatial audio featuring AI position sensing with Acoustic Echo Cancellation (AEC) from Philips BeClear.

Powered by the NXP i.MX 8M Mini applications processor, this technology enables soundbar manufacturers to deliver immersive, location-accurate game audio simultaneously with clear voice chat - a combination previously unachievable in gaming soundbars. The core technology enabling this breakthrough is AEC. For multiplayer voice chat to work during gameplay, the sound of the game needs to be blocked or cancelled while voice chat is transmitted through microphone arrays. Without this cancellation, other gamers on the chat would hear a jumbled mix of voice and game audio layered on top of their own game audio, resulting in unintelligible communication.

Powered by AI position sensing, Audioscenic’s position-adaptive audio technology Amphi Hi-D dynamically delivers consistent 3D audio across multiple speakers as gamers naturally move in their gaming space. This adaptivity presents a challenge for conventional AEC systems, which typically struggle with moving sound sources. The Philips BeClear solution is specially tuned to maintain voice clarity regardless of how the Hi-D system redistributes game audio based on player movement.

The technical demands of this system require significant processing power. With Philips BeClear AEC game audio reproduced through Hi-D that would otherwise make its way into microphones is cancelled out through an instantaneous convergence process. The NXP i.MX 8M Mini applications processor with Quad Arm Cortex-A53 running at 1.8 GHz per core and 8-channel PDM audio input delivers the computational power needed to process both the 3D sound positioning and real-time echo cancellation simultaneously.
