Apple patents audio signals that tell players which sound engine to use
Apple describes a method for packaging audio files with specific instructions that tell a media player which version of a sound processing tool to use. The file includes start and end points that define exactly where these instructions apply during playback.
In the filing’s own words
A system may utilize a signaling method to enable immersive audio rendering by a player. The system may package, in one or more bitstreams, audio content generated by a content creation tool for input to a type of audio renderer, selected from a plurality of types of audio renderers, a selected sub-type of the type of audio renderer, and a version of the selected sub-type of audio renderer. The one or more bitstreams may indicate start and end channel indexes in which the selected type, sub-type, and version are effective. The one or more bitstreams may be provided for transmission to a player. The one or more bitstreams may configure the player to utilize an audio renderer, for playback of the audio content in a playback environment, of the selected sub-type and the version indicated in the one or more bitstreams. Other aspects are also described and claimed.
What exactly they claim (claim 1)
1. A signaling method for immersive audio rendering by a player, comprising: packaging, in one or more bitstreams, i) audio content generated by a content creation tool for input to a type of audio renderer, selected from a plurality of types of audio renderers, ii) a selected sub-type of the type of audio renderer, and iii) a version of the selected sub-type of audio renderer, wherein the one or more bitstreams indicate a start channel index and an end channel index in which the selected type, sub-type, and version are effective; and providing the one or more bitstreams to be transmitted to a player, wherein the one or more bitstreams configure the player to utilize an audio renderer, for playback of the audio content in a playback environment, of the selected sub-type and the version signaled in the one or more bitstreams.
