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.
Claims21
An audio system comprising a data processor configured to spatialize sound that is associated with a visual element that is being display on a display, the processor to:
- split an audio signal into a plurality of sub-band audio signals that include a first sub-band signal in a first sub-band, and a second sub-band signal in a second sub-band;
- and
- generate a plurality of speaker driver signals by processing the first and second sub-band audio signals so that the first sub-band signal is spatialized to emanate from a first location of the visual element, and the second sub-band signal is spatialized to emanate from a second location of the visual element that is different than the first location.
A method for reproducing sound of a data object, the method comprising:
- splitting a voice signal of a data object into a first sub-band signal in a first sub-band, and a second sub-band signal in a second sub-band;
- and
- generating a plurality of speaker driver signals to produce sound of the object by a two-way speaker system, by processing the first sub-band signal into a tweeter or high frequency driver signal for the two-way speaker system, and the second sub-band signal into a woofer or low frequency driver signal for the two-way speaker system.
An article of manufacture comprising a machine-readable storage medium having stored therein instructions that configure a processor to:
- split a voice signal into a first sub-band signal in a first sub-band, and a second sub-band signal in a second sub-band;
- and
- generate a plurality of speaker driver signals to reproduce sound of the voice signal, in which sound of the first sub-band signal is produced by a first speaker driver and sound of the second sub-band signal is produced by a second speaker driver.
