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.
