    Abstract: In a method for reproducing sound of a data object, a voice signal of a data object is split into a first sub-band signal and a second sub-band signal, and speaker driver signals are generated to produce sound of the object by a two-way speaker system in which the first sub-band signal drives a tweeter or high frequency driver and the second sub-band signal drives a woofer or low frequency driver. In another aspect, the first and second sub-band signals are spatialized as virtual sources that are in different locations. Other aspects are also described and claimed.

    Abstract: An audio asset library containing audio assets formatted in accordance with a file format for spatial audio includes asset metadata that enables simulated reality (SR) application developers to compose sounds for use in SR applications. The audio assets are formatted to include audio data encoding a sound capable of being composed into a SR application along with asset metadata describing not only how the sound was encoded, but also how a listener in SR environment experiences the sound. A SR developer platform is configured so that developers can compose sound for SR objects using audio assets stored in the audio library, including editing the asset metadata to include transformation parameters that support dynamic transformation of the asset metadata in the SR environment to alter how the SR listener experiences the composed sound. Other embodiments are also described and claimed.

    Abstract: In some implementations, a method includes: obtaining user movement information, wherein the user movement information characterizes real-world body pose and trajectory information of the user; generating, from real-world user movement information and a predetermined placement of the virtual instrument in the computer generated reality (CGR) environment, a predicted virtual instrument interaction time for a virtual instrument interaction prior to the virtual instrument interaction occurring; determining whether or not the predicted virtual instrument interaction time falls within an acceptable temporal range around one of a plurality of temporal sound markers; and in response to determining that the predicted virtual instrument interaction time falls within the acceptable temporal range around a particular temporal sound marker of the plurality of temporal sound markers, quantizing the virtual instrument interaction by presenting play of the virtual instrument to match the particular temporal sound marker of the plurality of temporal sound markers.

    Abstract: Processing sound in an enhanced reality environment can include generating, based on an image of a physical environment, an acoustic model of the physical environment. Audio signals captured by a microphone array, can capture a sound in the physical environment. Based on these audio signals, one or more measured acoustic parameters of the physical environment can be generated. A target audio signal can be processed using the model of the physical environment and the measured acoustic parameters, resulting in a plurality of output audio channels having a virtual sound source with a virtual location. The output audio channels can be used to drive a plurality of speakers. Other aspects are also described and claimed.
