What is RP22? The New Immersive Audio Guidelines

14/09/2024

The RP22 Immersive Audio Guidelines, developed by CEDIA and the Consumer Technology Association (CTA), represent a significant advancement in how home audio systems are designed, installed, and experienced. These guidelines set a new standard for immersive audio, offering a detailed, objective set of performance metrics that both integrators and consumers can rely on.

One of the key innovations of the RP22 guidelines is the introduction of four distinct performance levels that help consumers and professionals align their expectations with the system’s capabilities. These levels range from Level 1, which ensures basic artistic intent is conveyed, to Level 4, which achieves the highest possible audio performance—often exceeding the standards of commercial cinema systems. This structure allows homeowners to choose an immersive audio system that meets their specific needs and budget while still delivering exceptional sound quality.

For professionals, RP22 provides comprehensive guidance on a variety of technical aspects, such as speaker placement, room acoustics, and bass management, ensuring that systems are optimised for their environment. The guidelines cover popular immersive audio formats like Dolby Atmos, DTS, and Auro-3D, and also include recommendations for managing seat-to-seat variation, a common challenge in home theatre design.

RP22 is not just about improving audio quality; it also aims to provide clarity for consumers, allowing them to make informed decisions about their home entertainment systems. By standardising performance benchmarks, it becomes easier for consumers to compare different setups and know exactly what level of immersive experience they can expect. For integrators, RP22 is a valuable tool to ensure they can design systems that meet or exceed client expectations.

Overall, the RP22 guidelines are a game-changer for anyone interested in immersive audio, whether they are building a home cinema or upgrading their current setup. They elevate both the art and science of home entertainment, ensuring that each system delivers an audio experience tailored to the space and the listener’s preferences.
