ECHO REFERENCE PRIORITIZATION AND SELECTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240304171 titled 'ECHO REFERENCE PRIORITIZATION AND SELECTION
Simplified Explanation: The patent application involves a method for managing echo in an audio environment by obtaining echo references from multiple audio devices, estimating the importance of each reference, selecting key references, and providing them to echo management systems.
- Multiple echo references are obtained, each corresponding to audio data from different audio devices.
- Importance estimation is done for each echo reference to determine its contribution to echo mitigation.
- Key echo references are selected based on importance estimation and provided to echo management systems.
Key Features and Innovation:
- Method for managing echo in an audio environment by selecting key echo references.
- Importance estimation for each echo reference to optimize echo mitigation.
- Selection of echo references based on their expected contribution to echo management.
Potential Applications: The technology can be applied in various audio environments such as conference rooms, auditoriums, and home entertainment systems to enhance audio quality by reducing echo.
Problems Solved: The technology addresses the issue of echo in audio environments by efficiently selecting and providing key echo references to echo management systems for effective mitigation.
Benefits:
- Improved audio quality by reducing echo in various audio environments.
- Enhanced user experience during audio playback.
- Optimal management of echo references for efficient echo mitigation.
Commercial Applications: The technology can be used in audio equipment manufacturing, conference room audio systems, and home entertainment systems to improve audio quality and user experience, potentially leading to increased sales and customer satisfaction.
Questions about Echo Management: 1. How does the technology estimate the importance of each echo reference? 2. What are the potential challenges in implementing this technology in different audio environments?

Original Abstract Submitted
some implementations involve obtaining a plurality of echo references, the plurality of echo references including at least one echo reference for each audio device of a plurality of audio devices in an audio environment, each echo reference corresponding to audio data being played back by one or more loudspeakers of one audio device of the plurality of audio devices. some examples involve making an importance estimation for each echo reference of the plurality of echo references. making the importance estimation may involve determining an expected contribution of each echo reference to mitigation of echo by at least one echo management system of at least one audio device of the audio environment. some implementations involve selecting, based at least in part on the importance estimation, one or more selected echo references and providing the one or more selected echo references to the at least one echo management system.
