QUANTIZING SPATIAL AUDIO PARAMETERS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240046939 titled 'QUANTIZING SPATIAL AUDIO PARAMETERS

Simplified Explanation

The patent application describes an apparatus for spatial audio encoding that quantizes and indexes a spatial audio direction parameter to create a quantized spatial audio direction index. This parameter is associated with a specific time sub-frame of a frequency sub-band of an audio frame. The apparatus also calculates a quantized spatial audio difference index by determining the difference between the quantized spatial audio direction index and a quantized average spatial audio direction index.

  • The apparatus is designed to encode spatial audio by quantizing and indexing the direction parameter.
  • The quantized spatial audio direction index represents the direction of the audio in a specific time and frequency sub-band.
  • The quantized spatial audio difference index measures the difference between the direction of the audio in a specific time and frequency sub-band and the average direction.
  • The apparatus allows for efficient encoding and decoding of spatial audio information.

Potential applications of this technology:

  • Virtual reality (VR) and augmented reality (AR) systems can use this technology to enhance the immersive audio experience for users.
  • Gaming consoles and platforms can utilize this technology to provide more realistic and immersive audio effects.
  • Audio streaming services can incorporate this technology to deliver spatial audio content to users, enhancing the listening experience.

Problems solved by this technology:

  • Traditional audio encoding methods may not accurately capture the spatial information of audio, resulting in a loss of immersive experience.
  • Spatial audio encoding can be computationally expensive and require large amounts of data, making it challenging to implement in real-time applications.
  • This technology addresses these issues by quantizing and indexing the spatial audio direction parameter, allowing for efficient encoding and decoding.

Benefits of this technology:

  • Improved spatial audio experience for users, providing a more immersive and realistic audio environment.
  • Efficient encoding and decoding of spatial audio, reducing computational requirements and data storage.
  • Compatibility with various audio applications, including VR, AR, gaming, and streaming services.


Original Abstract Submitted

there is inter alia disclosed an apparatus for spatial audio encoding configured to quantise and index a spatial audio direction parameter to form a quantised spatial audio direction index, wherein the spatial audio direction parameter is associated with a time sub frame of a frequency sub band of an audio frame; and determine a quantised spatial audio difference index by calculating the difference between the quantised spatial audio direction index and a quantised average spatial audio direction index.
