Multi-View Audio Processing with Real and Virtual Output Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio processing schemes in multi-view mode often experience audio resource conflicts due to newly started non-focus views preempting the audio resources of focus views.
Innovation Solution
A method and apparatus for audio processing in a multi-view mode that triggers corresponding views to perform audio output using matching sound output devices based on a policy where a first application uses a real sound output device and a non-first application uses a virtual sound output device, adjusting the audio output devices when a preset audio output adjusting event occurs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sound output device is bound to a presentation area in advance, then audio output can be automatically determined for each view, but newly started non-focus views may preempt audio resources of focus views causing audio resource conflicts
Solution Approach 1:
The patent segments the audio output device into two distinct components: a real sound output device (physical speaker) and a virtual sound output device (software interface). This segmentation allows the system to assign the virtual device to non-focus views and the real device to focus views, preventing resource preemption while maintaining automatic audio determination functionality.
Solution Approach 2:
The virtual sound output device acts as an intermediary between non-focus views and the actual audio hardware. By routing non-focus view audio through the virtual device rather than directly to the real speaker, the system prevents resource conflicts while still allowing multiple views to access audio resources simultaneously without interference.
2Adaptability or versatility
If multiple views can simultaneously access audio resources, then multi-view functionality is enhanced, but audio resource conflicts occur when non-focus views preempt focus view audio
Solution Approach 1:
The audio output device is segmented into real and virtual components, enabling multiple views to access audio resources simultaneously through different device types. Focus views access the real sound output device while non-focus views access the virtual sound output device, preventing conflicts while maintaining multi-view audio capability.
Solution Approach 2:
Different quality levels of audio output are assigned to different views based on their focus status. Focus views receive high-quality direct audio output through the real sound output device, while non-focus views receive audio through the virtual sound output device. This local differentiation resolves resource conflicts while preserving adaptability.

AI summary
A method and an apparatus for audio processing in a multi-view mode are provided. triggering, when a preset audio output adjusting event occurs, corresponding views to perform audio output by using matching sound output devices based on a policy that a first application uses a real sound output device and a non-first application uses a virtual sound output device, wherein the audio output adjusting event is an event causing the sound output devices used by the views to not match the policy, when a mixing mode is off, the first application is an application currently in an audio focus, and when the mixing mode is on, the first application is an application currently participating in mixing.
