Multi-Channel Audio Signal Coding Method and Apparatus - A simplified explanation of the abstract

This abstract first appeared for US patent application 18154486 titled 'Multi-Channel Audio Signal Coding Method and Apparatus

Simplified Explanation

The patent application describes a method for coding multi-channel audio signals. Here is a simplified explanation of the abstract:

  • The method starts by obtaining a first audio frame to be encoded.
  • The channel signals are paired according to two different pairing manners to obtain two sets of channel pairs.
  • The correlation values of the channel pairs in each set are calculated and summed up.
  • Based on the sums of correlation values, a target pairing manner is determined for encoding the channel signals.
  • The channel signals are then encoded using the channel pair set corresponding to the target pairing manner.

Potential applications of this technology:

  • Audio compression and encoding algorithms
  • Surround sound systems
  • Virtual reality and augmented reality audio processing

Problems solved by this technology:

  • Efficient coding of multi-channel audio signals
  • Optimal pairing of channel signals for encoding
  • Improved audio quality and compression ratio

Benefits of this technology:

  • Enhanced audio coding efficiency
  • Improved audio quality and fidelity
  • Reduced bandwidth and storage requirements for audio data


Original Abstract Submitted

A multi-channel audio signal coding method includes obtaining a to-be-encoded first audio frame, pairing at least five channel signals according to a first pairing manner to obtain a first channel pair set, obtaining a first sum of correlation values of the first channel pair set, where one channel pair has one correlation value, pairing the at least five channel signals according to a second pairing manner to obtain a second channel pair set, obtaining a second sum of correlation values of the second channel pair set, determining a target pairing manner of the at least five channel signals based on the first sum of correlation values and the second sum of correlation values, and encoding the at least five channel signals based on a channel pair set corresponding to the target pairing manner, where the target pairing manner is the first pairing manner or the second pairing manner.
