What is AFC Image?
With a conventional stereo configuration, the acoustic image will vary according to the listener’s position. Immersive systems, on the other hand, allow acoustic images to be placed as they are needed to produce the desired effect, and their position remains absolute regardless of listener location.
By precisely varying the output balance from the system’s multiple speakers, sound can be moved to match programming and staging needs. Smoothly moving object-based audio around the place including the vertical, provides a level of freedom opening up new possibilities for content delivery and staging.
Speaker zoning allows audio objects to be assigned to specific sets of speakers within the system. AFC Image allows up to 32 speaker zones to be defined for precise yet flexible control of perceived object position. Audio objects assigned to zones allow sounds to be sourced from only the desired speakers within the system.
Rendering Area Conversion
For object-based rendering, the user can convert the DAW or console panning/rendering area to any configuration from a basic cube to a 16-sided polygon within which objects can be positioned. Three layers are available with heights that can be individually defined by the user. All of this means that, for example, objects being output from a console could be rendered and controlled within the stage area from the console, while objects being output from a DAW are rendered and controlled within the audience area.
Channel-based Audio Also Supported
Object-based audio is extremely versatile and controllable, while channel-based audio is still a good choice in many situations. AFC Image supports both object and channel-based audio, giving creators the best of both worlds. Processing for a combination of up to 128 objects provides ample capacity for the most demanding of productions, while zoning provides versatile support for channel-based production.
In a real acoustic space, perceived reverberation varies with the listening position. A knowledge base built up over years of designing theaters and halls has allowed Yamaha to develop original 3D reverberation technology that creates reverb optimized for the locations of individual objects, resulting in a deeper, more realistic sound field. The directionality and spread of the reverberation can be freely controlled via an intuitive graphical interface.
Immersive sound can be experienced in headphones too, and AFC Image provides the necessary binaural rendering tools. Immersive content can be output in 2-channel binaural form for monitoring or simply enjoying the immersive experienced in headphones. AFC Image can also output immersive sound in binaural form for streaming to remote locations.
