==AUDIO ENCODER, AUDIO DECODER, METHODS AND COMPUTER PROGRAM USING JOINTLY ENCODED RESIDUAL SIGNALS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240029744 titled 'AUDIO ENCODER, AUDIO DECODER, METHODS AND COMPUTER PROGRAM USING JOINTLY ENCODED RESIDUAL SIGNALS

==Simplified Explanation==

The abstract describes an audio decoder that can provide at least four audio channel signals based on an encoded representation. It utilizes a multi-channel decoding technique to generate a first residual signal and a second residual signal from a jointly encoded representation of the first and second residual signals. The decoder then uses a residual-signal-assisted multi-channel decoding method to combine the first downmix signal with the first residual signal to produce a first audio channel signal, and the second downmix signal with the second residual signal to produce a second audio channel signal. Similarly, it generates a third and fourth audio channel signal using the second downmix signal and the second residual signal.

* The audio decoder provides four audio channel signals based on an encoded representation.
* It uses multi-channel decoding to generate residual signals from a jointly encoded representation.
* The decoder employs residual-signal-assisted multi-channel decoding to combine downmix signals with the residual signals to produce audio channel signals.

Potential applications of this technology:
* Surround sound systems in home theaters and cinemas.
* Virtual reality and augmented reality audio experiences.
* Gaming consoles and immersive gaming experiences.
* Audio production and post-production for film and music.

Problems solved by this technology:
* Efficient decoding and reproduction of multi-channel audio signals.
* Enhanced spatial audio experience for the listeners.
* Improved audio quality and immersion in various applications.

Benefits of this technology:
* Provides a more immersive and realistic audio experience.
* Enables accurate localization of sound sources.
* Enhances the overall audio quality and fidelity.
* Supports the creation of multi-channel audio content with reduced bandwidth requirements.


==Original Abstract Submitted==

an audio decoder for providing at least four audio channel signals on the basis of an encoded representation is configured to provide a first residual signal and a second residual signal on the basis of a jointly encoded representation of the first residual signal and of the second residual signal using a multi-channel decoding. the audio decoder is configured to provide a first audio channel signal and a second audio channel signal on the basis of a first downmix signal and the first residual signal using a residual-signal-assisted multi-channel decoding. the audio decoder is configured to provide a third audio channel signal and a fourth audio channel signal on the basis of a second downmix signal and the second residual signal using a residual-signal-assisted multi-channel decoding. an audio encoder is based on corresponding considerations.
