Splitting a Voice Signal into Multiple Point Sources - A simplified explanation of the abstract

This abstract first appeared for US patent application 17962935 titled 'Splitting a Voice Signal into Multiple Point Sources

Simplified Explanation

The patent application describes a method for reproducing sound of a data object using a two-way speaker system. Here are the key points:

• The voice signal of a data object is split into two sub-band signals.
• Speaker driver signals are generated to produce sound using a two-way speaker system.
• The first sub-band signal drives a tweeter or high frequency driver.
• The second sub-band signal drives a woofer or low frequency driver.
• The first and second sub-band signals can be spatialized as virtual sources in different locations.

Potential applications of this technology:

• Home audio systems
• Car audio systems
• Virtual reality and augmented reality applications
• Gaming consoles and devices
• Professional audio equipment

Problems solved by this technology:

• Improved sound reproduction of data objects
• Enhanced audio experience with spatialized sound
• Better separation of high and low frequency sounds

Benefits of this technology:

• High-quality sound reproduction
• Immersive audio experience
• Clear and distinct separation of different frequency ranges

Original Abstract Submitted

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.
