Audio Volume Balancing in Multi-Device Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-person video conferences, participants often experience varying audio volumes due to differences in speaking habits and terminal devices, leading to discomfort and difficulty in understanding certain voices, either because they are too quiet or too loud.
Innovation Solution
An electronic device method that detects conditions and adjusts audio output parameters to balance volumes by switching between different parameter settings, ensuring that the output from different communication objects does not differ significantly, thereby optimizing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If audio output parameters are not adjusted, then the device complexity is low, but the audio volume balance deteriorates causing user discomfort
Solution Approach 1:
The system automatically detects audio parameters and adjusts volumes without user intervention. The processor monitors audio output from multiple communication objects and autonomously applies gain adjustments to achieve balanced volumes, eliminating the need for manual user configuration while maintaining audio quality.
Solution Approach 2:
The system dynamically changes audio output parameters (gain values) based on detected audio characteristics. By monitoring the original volumes of different communication objects and calculating appropriate gain adjustments, the system transforms the audio parameters to achieve balanced output volumes across all participants.
2Ease of operation
If manual volume adjustment is required, then the audio volume balance can be improved, but the user experience deteriorates due to repeated adjustments
Solution Approach 1:
The system performs preliminary audio parameter detection and gain calculation before audio output. By pre-processing the audio signals and establishing appropriate gain values in advance, the system eliminates the need for subsequent manual adjustments during the communication session, saving user time and improving experience.
Solution Approach 2:
The system continuously monitors audio output parameters and adjusts gain values in real-time to maintain balanced volumes. This closed-loop feedback mechanism ensures that audio volume balance is maintained automatically throughout the communication session without requiring user intervention or repeated adjustments.
3Reliability
If different audio parameters are used for different communication objects, then the individual audio quality is preserved, but the overall audio balance deteriorates
Solution Approach 1:
The system applies different gain values to different communication objects based on their individual audio characteristics. Each audio stream receives customized gain adjustment tailored to its original volume level, preserving the unique quality characteristics of each participant while achieving overall balance through localized parameter optimization.

AI summary
A processing method includes detecting whether a condition is satisfied and in response to the condition being satisfied, controlling an electronic device to switch from a first state to a second state. In the first state, the electronic device is configured to output a first audio from a first communication object with a first parameter and a second audio from a second communication object with a second parameter. In the second state, the electronic device is configured to output the first audio from the first communication object with a third parameter and the second audio from the second communication object with a fourth parameter. Switching the electronic device from the first state to the second state includes adjusting the first parameter to the third parameter in a first method and adjusting the second parameter to the fourth parameter in a second method.
