PROCESSING OF AUDIO SIGNALS FROM MULTIPLE MICROPHONES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17814660 titled 'PROCESSING OF AUDIO SIGNALS FROM MULTIPLE MICROPHONES

Simplified Explanation

The abstract of this patent application describes a device that can process audio signals from multiple microphones to determine the direction of sound sources. The device includes a memory to store instructions and processors to analyze the audio signals and generate direction-of-arrival information. This information, along with associated class or embedding data, can be sent to another device.

  • The device has a memory to store instructions and one or more processors to receive audio signals from multiple microphones.
  • The processors analyze the audio signals to determine the direction of sound sources.
  • Direction-of-arrival information is generated based on the analysis.
  • The device can send data, including the direction-of-arrival information and associated class or embedding data, to another device.

Potential Applications

  • Sound localization and tracking systems for security purposes.
  • Audio conferencing systems that can identify the direction of speakers.
  • Augmented reality applications that can enhance sound based on its direction.
  • Noise cancellation systems that can identify and suppress specific sound sources.

Problems Solved

  • Accurately determining the direction of sound sources in a multi-microphone setup.
  • Efficiently processing audio signals to generate direction-of-arrival information.
  • Transmitting relevant data, including direction-of-arrival information, to other devices.

Benefits

  • Improved accuracy in determining the direction of sound sources.
  • Enhanced audio experiences in various applications.
  • Potential for improved security and surveillance systems.
  • Efficient and effective noise cancellation capabilities.


Original Abstract Submitted

A first device includes a memory configured to store instructions and one or more processors configured to receive audio signals from multiple microphones. The one or more processors are configured to process the audio signals to generate direction-of-arrival information corresponding to one or more sources of sound represented in one or more of the audio signals. The one or more processors are also configured to and send, to a second device, data based on the direction-of-arrival information and a class or embedding associated with the direction-of-arrival information.
