COMPRESSION OF DECOMPOSED REPRESENTATIONS OF A SOUND FIELD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240276166 titled 'COMPRESSION OF DECOMPOSED REPRESENTATIONS OF A SOUND FIELD

Simplified Explanation: The patent application describes techniques for compressing decomposed representations of a sound field, using a device with memory and processing circuitry to extract foreground components and directional information from scene-based audio data.

  • The memory stores a bitstream representing ambisonic coefficients of a sound field.
  • The processing circuitry extracts foreground components and corresponding directional information from the bitstream.
  • Dequantization is applied to the directional information to obtain dequantized directional information.
  • A reconstructed version of the scene-based audio data is obtained based on the foreground components and dequantized directional information.

Key Features and Innovation:

  • Compression of decomposed representations of a sound field.
  • Extraction of foreground components and directional information from scene-based audio data.
  • Dequantization of directional information for reconstruction of the audio data.

Potential Applications: The technology can be used in virtual reality, gaming, audio production, and immersive sound experiences.

Problems Solved: This technology addresses the need for efficient compression and processing of complex sound field data.

Benefits:

  • Improved storage efficiency for scene-based audio data.
  • Enhanced reconstruction of sound fields for immersive experiences.

Commercial Applications: The technology can be applied in virtual reality headsets, gaming consoles, audio editing software, and entertainment systems.

Prior Art: Prior research in the field of audio compression and spatial audio processing may provide insights into similar techniques and technologies.

Frequently Updated Research: Stay updated on advancements in audio compression algorithms, spatial audio processing techniques, and immersive sound technologies.

Questions about Sound Field Compression: 1. How does this technology improve the efficiency of storing and processing scene-based audio data? 2. What are the potential applications of this technology in the entertainment industry?


Original Abstract Submitted

in general, techniques are described for compressing decomposed representations of a sound field. a device comprising a memory and processing circuitry may be configured to perform the techniques. the memory may be configured to store a bitstream representative of scene-based audio data, the scene-based audio data comprising ambisonic coefficients representative of a soundfield. the processing circuitry may be configured to process the bitstream to extract foreground components and corresponding foreground directional information, dequantize the corresponding foreground directional information to obtain corresponding dequantized directional information, and obtain, based on the foreground components and the corresponding dequantized foreground directional information, a reconstructed version of the scene-based audio data.
