Separated Audio Playback Routing to Prevent Sound Drops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices experience increased current consumption and sound drops when switching sound sources between processors during sound source separation playback, particularly when transitioning between active and inactive states of the sound source separation playback function.
Innovation Solution
The electronic device employs a first and second processor to manage audio data processing, storing and processing audio data separately for internal and external devices, respectively, and converting data formats as needed to minimize processor switches and maintain seamless audio output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sound source separation playback function is activated and sound sources are processed through different processors, then audio output quality is improved, but current consumption increases
Solution Approach 1:
The patent divides audio data into multiple storage areas (first storage area for first sound source, second storage area for second sound source) and processes them through different processors (first processor and second processor) simultaneously. This segmentation allows independent processing of audio streams, maintaining high audio output quality while enabling efficient resource management to control current consumption.
2Adaptability or versatility
If the processor for sound source processing is switched, then audio output flexibility is improved, but sound drops occur
Solution Approach 1:
The patent performs preliminary actions by determining in advance whether the sound source separation playback function is active or inactive, and pre-configuring the appropriate processing path. When active, it pre-arranges for different processors to handle different sound sources; when inactive, it pre-arranges for a single processor to handle all sound sources. This prevents mid-processing switches that would cause sound drops.
Solution Approach 2:
The patent implements dynamic processing by adjusting the audio processing configuration based on the state of the sound source separation playback function. The system dynamically switches between two operational modes: (1) single-processor mode for mixed audio output when the function is inactive, and (2) multi-processor mode for separated audio output when the function is active. This dynamic adaptation maintains audio continuity while providing flexibility.
