Abstract

The techniques disclosed herein can enable a system to coordinate the processing of object-based audio and channel-based audio generated by multiple applications. The system determines a spatialization technology to utilize based on contextual data. In some configurations, the contextual data can indicate the capabilities of one or more computing resources. In some configurations, the contextual data can also indicate preferences. The preferences, for example, can indicate user preferences for a type of spatialization technology, e.g., Dolby Atmos, over another type of spatialization technology, e.g., DTSX. Based on the contextual data, the system can select a spatialization technology and a corresponding encoder to process the input signals to generate a spatially encoded stream that appropriately renders the audio of multiple applications to an available output device. The techniques disclosed herein also allow a system to dynamically change the spatialization technologies during use.
