Abstract: A voice signal of a data object (eg. an animated Virtual Reality avatar) 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. The first and second sub-band signals are spatialized as virtual sources appearing to emanate sound from different locations based on room acoustics.

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: 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.
