Terminal Audio Channel Separation for Simultaneous Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal devices experience poor sound effects when playing two different pieces of audio data simultaneously, as they are mixed and played by a single audio output device, leading to inadequate human-machine interaction and user experience.
Innovation Solution
The method involves converting first and second audio data into separate channels and outputting them to different audio output devices or combining them into a third channel for path switching, allowing distinct audio data to be played on different devices or a single device, thereby enhancing sound quality and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different pieces of audio data are mixed and played by a single audio output device, then the terminal device can play multiple audio data simultaneously with simple device configuration, but the sound effects deteriorate and user experience worsens
Solution Approach 1:
The patent divides the audio output into separate channels, with each channel dedicated to a specific audio data stream. Instead of mixing multiple audio data through a single output device, the system segments the audio processing path so that first audio data and second audio data are routed to different audio output devices through separate channels, preventing sound mixing and maintaining audio quality.
2Manufacturing precision
If audio data are converted into separate channels and output to different audio output devices, then sound effect quality improves, but device complexity increases
Solution Approach 1:
The patent implements a universal audio processing framework that can adaptively route different audio data streams to appropriate output devices based on channel configuration. The audio processing system is designed to handle both single-channel and multi-channel scenarios, automatically selecting the appropriate output path without requiring separate dedicated hardware for each audio stream.
3Manufacturing precision
If audio data are converted into separate channels, then sound effect quality improves, but the processing complexity increases
Solution Approach 1:
The patent performs channel conversion and audio data separation in advance, before the actual playback occurs. By pre-processing the audio data into separate channels and pre-configuring the output routing paths, the system eliminates the need for complex real-time mixing and routing decisions during playback, thereby reducing processing complexity while maintaining audio quality.

AI summary
The present disclosure relates to audio data processing methods and devices. One example method includes obtaining a first audio data and a second audio data, converting the first audio data into a first channel of audio data and converting the second audio data into a second channel of audio data, and at least one of outputting the first channel of audio data to a first audio output device or outputting the second channel of audio data to a second audio output device.
