METHODS, APPARATUS AND SYSTEMS FOR ENCODING AND DECODING OF DIRECTIONAL SOUND SOURCES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240212693 titled 'METHODS, APPARATUS AND SYSTEMS FOR ENCODING AND DECODING OF DIRECTIONAL SOUND SOURCES

The disclosed methods in this patent application involve encoding or decoding directional audio data. Encoding methods may include receiving a mono audio signal corresponding to an audio object and a representation of a radiation pattern corresponding to the audio object. The radiation pattern includes sound levels for a plurality of sample times, frequency bands, and directions. The methods also involve encoding the mono audio signal and the source radiation pattern to determine radiation pattern metadata. Encoding the radiation pattern involves determining a spherical harmonic transform of the representation of the radiation pattern and compressing the spherical harmonic transform to obtain encoded radiation pattern metadata.

  • Receiving a mono audio signal and a radiation pattern representation
  • Encoding the mono audio signal and radiation pattern to determine metadata
  • Determining a spherical harmonic transform of the radiation pattern
