EFFICIENT RENDERING OF VIRTUAL SOUNDFIELDS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240048933 titled 'EFFICIENT RENDERING OF VIRTUAL SOUNDFIELDS

Simplified Explanation

The abstract describes an audio system and method that spatially renders audio signals using modified virtual speaker panning. The system includes a fixed number of virtual speakers, and a subset of these virtual speakers is dynamically selected and used. The subset of virtual speakers can be chosen using a low energy speaker detection and culling method, a source geometry-based culling method, or both. Certain processing blocks in the decoder/virtualizer can be bypassed based on the energy level of the audio signal or the location of the sound source relative to the user. In some cases, a virtual speaker designated as active at one time can also be designated as active at another time to ensure processing completion.

  • The audio system uses modified virtual speaker panning to spatially render audio signals.
  • It includes a fixed number of virtual speakers.
  • A subset of virtual speakers is dynamically selected and used.
  • The subset of virtual speakers can be chosen using a low energy speaker detection and culling method, a source geometry-based culling method, or both.
  • Certain processing blocks in the decoder/virtualizer can be bypassed based on the energy level of the audio signal or the location of the sound source relative to the user.
  • Virtual speakers can be designated as active at different times to ensure processing completion.

Potential Applications:

  • Surround sound systems for home theaters or gaming.
  • Virtual reality (VR) and augmented reality (AR) audio systems.
  • Immersive audio experiences in theme parks or museums.
  • Audio systems for live performances or concerts.

Problems Solved:

  • Provides a more realistic and immersive audio experience by spatially rendering audio signals.
  • Allows for dynamic selection and use of virtual speakers based on the audio content and source location.
  • Reduces processing requirements by bypassing unnecessary blocks based on energy levels or sound source location.

Benefits:

  • Enhanced audio quality and immersion for users.
  • Efficient use of virtual speakers and processing resources.
  • Flexibility in adapting to different audio content and source locations.
  • Improved overall audio experience in various applications.


Original Abstract Submitted

an audio system and method of spatially rendering audio signals that uses modified virtual speaker panning is disclosed. the audio system may include a fixed number f of virtual speakers, and the modified virtual speaker panning may dynamically select and use a subset p of the fixed virtual speakers. the subset p of virtual speakers may be selected using a low energy speaker detection and culling method, a source geometry-based culling method, or both. one or more processing blocks in the decoder/virtualizer may be bypassed based on the energy level of the associated audio signal or the location of the sound source relative to the user/listener, respectively. in some embodiments, a virtual speaker that is designated as an active virtual speaker at a first time, may also be designated as an active virtual speaker at a second time to ensure the processing completes.
