Object Audio Coding - A simplified explanation of the abstract
This abstract first appeared for US patent application 18454409 titled 'Object Audio Coding
Simplified Explanation
The patent application describes a computer-implemented method for obtaining object audio and metadata, converting the object audio to time-frequency domain Ambisonics audio based on the metadata, and encoding the audio and metadata as bitstreams for storage or transmission.
- Object audio and metadata are obtained.
- Object audio is converted to time-frequency domain Ambisonics audio using the metadata.
- The time-frequency domain Ambisonics audio and a subset of the metadata are encoded as bitstreams.
Potential Applications
This technology could be used in virtual reality and augmented reality applications, 3D audio production, gaming, and immersive audio experiences.
Problems Solved
This technology solves the problem of efficiently storing and transmitting spatial audio data along with metadata that describes the audio.
Benefits
The benefits of this technology include improved spatial audio quality, enhanced immersive experiences, and more efficient storage and transmission of audio data.
Potential Commercial Applications
- Virtual reality and augmented reality content creation tools
- Gaming platforms with immersive audio capabilities
Possible Prior Art
One possible prior art could be the use of Ambisonics audio technology in virtual reality and gaming applications.

The article does not address any potential limitations or challenges that may arise when implementing this technology in practical settings.
Original Abstract Submitted
In one aspect, a computer-implemented method, includes obtaining object audio and metadata that spatially describes the object audio, converting the object audio to time-frequency domain Ambisonics audio based on the metadata, and encoding the time-frequency domain Ambisonics audio and a subset of the metadata as one or more bitstreams to be stored in computer-readable memory or transmitted to a remote device.
