==AUDIO DECODER, METHOD AND COMPUTER PROGRAM USING A ZERO-INPUT-RESPONSE TO OBTAIN A SMOOTH TRANSITION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240046941 titled 'AUDIO DECODER, METHOD AND COMPUTER PROGRAM USING A ZERO-INPUT-RESPONSE TO OBTAIN A SMOOTH TRANSITION

==Simplified Explanation==

The abstract describes an audio decoder that provides decoded audio information based on encoded audio information. It includes a linear-prediction-domain decoder and a frequency domain decoder. The decoder also has a transition processor that modifies the second decoded audio information to achieve a smooth transition between the first and modified second decoded audio information.

* The audio decoder provides decoded audio information based on encoded audio information.
* It includes a linear-prediction-domain decoder and a frequency domain decoder.
* The transition processor obtains a zero-input-response of a linear predictive filtering.
* The initial state of the linear predictive filtering depends on the first and second decoded audio information.
* The second decoded audio information is modified based on the zero-input-response.
* The modification ensures a smooth transition between the first and modified second decoded audio information.

Potential applications of this technology:

* Audio decoding in various devices such as smartphones, tablets, and computers.
* Streaming services for delivering high-quality audio.
* Audio compression and decompression algorithms.

Problems solved by this technology:

* Ensures accurate decoding of audio information encoded in different domains.
* Provides a smooth transition between different decoded audio frames.
* Improves the overall audio quality and listening experience.

Benefits of this technology:

* Enhanced audio decoding capabilities.
* Seamless transitions between different audio frames.
* Improved audio quality and fidelity.
* Better user experience in audio playback.


==Original Abstract Submitted==

an audio decoder for providing a decoded audio information on the basis of an encoded audio information includes a linear-prediction-domain decoder configured to provide a first decoded audio information on the basis of an audio frame encoded in a linear prediction domain, a frequency domain decoder configured to provide a second decoded audio information on the basis of an audio frame encoded in a frequency domain, and a transition processor. the transition processor is configured to obtain a zero-input-response of a linear predictive filtering, wherein an initial state of the linear predictive filtering is defined depending on the first decoded audio information and the second decoded audio information, and modify the second decoded audio information depending on the zero-input-response, to obtain a smooth transition between the first and the modified second decoded audio information.
