Audio Processing Method for Multi-Channel Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart devices can only play a single-channel audio track from multiple channels of audio tracks, failing to meet the needs of multiple users in a scenario where different audio tracks are required for each user.
Innovation Solution
An audio processing method that parses a multimedia file to identify multiple channels, establishes a relationship between each channel and a playback earphone, decodes each channel using a preset decoder, and plays each channel through the corresponding earphone based on a pulse modulation code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart device plays only a single-channel audio track from multiple channels, then the device complexity remains low and operation is simple, but the adaptability to meet different users' audio needs deteriorates
Solution Approach 1:
The patent segments the audio playback system by establishing separate playback paths for different audio channels. Each audio channel is independently decoded and routed to corresponding playback earphones, allowing multiple users to simultaneously access different audio tracks from the same multimedia file without increasing overall system complexity
Solution Approach 2:
The patent makes the audio playback system universal by enabling it to handle both single-channel and multi-channel audio scenarios. The system can adaptively select between playing a single audio track or multiple audio tracks simultaneously based on the number of connected playback earphones, thus improving adaptability without requiring separate dedicated systems
2Adaptability or versatility
If multiple channels of audio tracks are played simultaneously through multiple playback earphones, then the adaptability to meet different users' needs is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic audio playback where the system automatically adjusts the number of audio channels to be played based on the number of connected playback earphones. When one earphone is connected, only one audio channel is played; when multiple earphones are connected, multiple audio channels are simultaneously played. This dynamic adaptation avoids the need for a permanently complex multi-channel playback system
Solution Approach 2:
The system performs self-service by automatically detecting the number of connected playback earphones and independently configuring the audio playback without requiring manual user setup. The system autonomously establishes the correspondence between audio channels and playback earphones, reducing the operational complexity for users

AI summary
The present disclosure provides an audio processing method and an electronic device. The method includes: based on that a to-be-played multimedia file includes multiple channels of audio tracks, parsing the to-be-played multimedia file to obtain the multiple channels of audio tracks of the to-be-played multimedia file; determining at least two channels of target audio tracks from the multiple channels of audio tracks, and establishing a corresponding relationship between each channel of target audio track and each playback earphone; decoding each channel of target audio track based on a preset decoder corresponding to each channel of target audio track to obtain a pulse modulation code corresponding to each channel of target audio track; playing each channel of target audio track through the playback earphone corresponding to each channel of target audio track based on the pulse modulation code corresponding to each channel of target audio track and the corresponding relationship.
