Dual Audio Stream Processing for Video Conferencing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conference systems process multiple audio streams using a single audio profile, which fails to meet the unique requirements of different audio streams, leading to suboptimal sound quality and user experience in various virtual events.
Innovation Solution
Implementing dual audio stream processing and transmission systems that allow for individual audio streams to be processed based on their specific requirements, using distinct audio profiles for different types of audio signals, such as speech and music, to optimize sound quality and bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single audio profile is used to process multiple audio streams, then device complexity is reduced and ease of operation is improved, but sound quality and user experience deteriorate because unique requirements of different audio streams cannot be met
Solution Approach 1:
The patent divides the audio processing system into multiple independent audio profiles (e.g., speech profile, music profile, ambient profile), each optimized for specific audio stream types. This segmentation allows each audio stream to be processed by a dedicated profile, improving sound quality while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent applies different processing characteristics to different parts of the audio system by assigning specific audio profiles to specific audio streams based on their type. For example, speech streams receive noise suppression and enhancement processing, while music streams receive minimal processing to preserve fidelity. This local quality approach ensures each audio stream receives appropriate processing without requiring complete system redesign.
2Manufacturing precision
If individual audio profiles are used for different audio streams, then sound quality and user experience are improved, but device complexity increases
Solution Approach 1:
The patent creates a universal audio processing framework that can handle multiple audio stream types through a common set of audio profiles. The system universally applies the same architectural approach (profile selection and switching) across all audio streams, regardless of type, which manages complexity through standardized processes while still providing specialized processing for each stream.
Solution Approach 2:
The patent manages complexity by dynamically changing processing parameters based on audio stream type identification. The system automatically adjusts profile selection, processing intensity, and algorithm parameters according to the detected audio stream characteristics, allowing sophisticated processing without requiring manual configuration or complex hardwired systems.
3Loss of energy
If a single audio profile is used for all audio streams, then bandwidth usage is reduced, but sound quality deteriorates due to suboptimal processing
Solution Approach 1:
The patent applies processing at the appropriate level for each audio stream type rather than uniformly to all streams. Speech streams receive intensive processing (noise suppression, enhancement) when needed, while music and ambient streams receive minimal or no processing. This partial action approach optimizes bandwidth usage by applying processing only where necessary while maintaining sound quality for critical streams.

AI summary
Systems and methods for dual audio stream processing and transmission are provided. For example, a method may include establishing, by a video conference provider, a virtual event having a plurality of participants. Each participant may exchange one or more audio or video streams via the virtual event using a plurality of client devices. The method may also include receiving, by the video conference provider, a first audio stream from a first client device and receiving, by the video conference provider, a second audio stream from the first client device. The first audio stream may be processed via a first audio process and the second audio stream may be processed via a second audio process to generate a first processed stream and a second processed stream, respectively. The method may include transmitting, by the video conference provider, the first processed stream and the second processed stream to a second client device.
