Audio Stream Processing with User Preference Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio communication systems fail to adapt to individual user preferences for noise suppression levels, leading to dissatisfaction with the perceived quality of audio streams, as they do not account for varying user preferences based on personal, cultural, and environmental factors.
Innovation Solution
A method where a first node sends information about user preferences for acoustic characteristics, such as noise suppression levels, speech levels, and bandwidth, to a second node, which processes and transmits the audio stream accordingly, allowing for personalized audio settings during session setup or ongoing sessions.

Engineering Contradiction Analysis
1Object-affected harmful factors
If aggressive noise suppression is applied to improve audio quality, then background noise is reduced, but speech quality deteriorates with clipping and codec artifacts
Solution Approach 1:
The system dynamically adjusts noise suppression parameters based on real-time audio conditions and user preferences. The second node modifies audio stream characteristics (noise suppression level, speech level, bandwidth) dynamically rather than applying fixed aggressive suppression, allowing adaptation between noise reduction and speech quality preservation depending on the situation.
Solution Approach 2:
The invention changes multiple audio parameters simultaneously (noise suppression level, speech level, bandwidth) rather than relying solely on aggressive noise suppression. By adjusting these parameters based on user preference information, the system achieves noise reduction while maintaining speech quality through coordinated parameter modification.
2Adaptability or versatility
If individual user preferences for noise suppression are implemented, then user satisfaction improves, but system complexity increases
Solution Approach 1:
The second node acts as an intermediary that receives user preference information from the first node and applies the appropriate audio processing. This distributes the complexity across network nodes rather than concentrating it in one device, allowing each node to remain relatively simple while the system as a whole achieves high adaptability.
Solution Approach 2:
The system uses universal audio processing mechanisms that can handle multiple user preferences and scenarios through a single framework. The same processing infrastructure adapts to different users by receiving preference information, avoiding the need for separate complex systems for each user type.

AI summary
A method and a first node for managing processing of an audio stream as well as a method and a second node for enabling management, by a first node, of processing of an audio stream and corresponding computer programs and computer program products are disclosed. The audio stream is receivable from the second node. The first node sends, to the second node, information relating to at least one preference concerning acoustic characteristics of the audio stream. The second node processes the audio stream in response to the information relating to the at least one preference concerning the acoustic characteristics. The second node transmits the audio stream to the first node.
