i.MX 8M SoC-Based Solution Enables Immersive 3D Audio

NXP Semiconductors has announced its Immersiv3D audio solution for the smart home market. The solution combines NXP software on its i.MX 8M Mini applications processor and will support both Dolby Atmos and DTS:X immersive audio technologies in future devices that integrate the i.MX 8M Mini SoC. The i.MX 8M Mini also brings smart capabilities like voice control to a broader range of consumer devices including soundbars, smart speakers, and AV receivers with the option for adding additional speakers to distribute smart voice control and immersive audio throughout the home.

TVs and audio systems are becoming more advanced thanks in large part to the development of Dolby Atmos and DTS:X. Both technologies are a leap forward from surround sound and transport listeners with moving audio that fills the room and flows all around them. Listeners will feel like they’re inside the action as the sounds of people, places, thing, and music come alive with breathtaking realism. NXP’s Immersiv3D audio solution was designed to enable OEMs to bring to market affordable consumer audio devices capable of supporting Dolby Atmos and DTS:X in their next-generation devices.

Conventional design approaches to audio systems use Digital Signal Processors (DSPs) to deliver complex, controlled and low-latency audio processing to enable audio and video synchronization. But Traditional embedded systems have evolved over time, and today they are capable of processing the latest 3D audio formats, but audio systems need to be designed to take advantage of today’s advanced processor cores. In conjunction with the NXP i.MX 8M family of processors, the Immersiv3D audio solution introduces an advanced approach that features scalable audio processing integration into the SoC Arm cores. This approach eliminates the need for expensive discrete DSPs, and also once-proprietary DSP design foundations, to embrace licensable cores.

The solution delivers high-end audio features such as immersive multi-channel audio playback, natural language processing and voice capabilities to fit today’s digitally savvy connected consumer. The NXP Immersiv3D audio solution gives audio developers, designers and integrators a leap forward to add intelligence and Artificial Intelligence (AI) functionality while reducing cost. This includes development of enhancements like selective noise canceling where only certain sound elements are removed like car traffic or speech processing like changing speaker dialect or languages.

The solution introduces an easy-to-use, low-cost enablement for voice capability expansion. Audio systems built using NXP’s Immersiv3D with the i.MX 8M Mini applications processor will give consumers the flexibility to add different audio speakers, regardless of brand, to stream simultaneous and synchronized audio with voice control from their systems.

NXP showcased its i.MX applications processor family including Immersiv3D at the CES 2019 show.
