Livestream Audio Channel Separation for Noise-Free Background Music
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing livestreaming solutions suffer from poor audio effects due to background music containing environmental noise and being played by devices of poor quality, which degrades the overall audio experience.
Innovation Solution
A livestreaming audio processing method and device that separates audio data from a streamer's voice and background music using different channels, allowing the background music to be recorded without environmental noise and played separately to enhance the audio experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If background music is recorded together with streamer's voice using the same audio channel, then the audio recording process is simple, but the background music contains environmental noise which degrades audio quality
Solution Approach 1:
The patent divides the audio recording process into separate channels: one channel records the streamer's voice, while another channel records the background music. This segmentation allows each audio source to be captured independently without environmental noise contamination, thereby improving audio quality while maintaining recording simplicity through automated multi-channel processing.
Solution Approach 2:
The patent extracts the background music recording from the general audio recording process by dedicating a separate audio channel specifically for background music. This extraction enables the background music to be recorded without picking up environmental noise that would otherwise be captured in a combined recording channel, thus resolving the quality issue.
2Ease of operation
If background music is played through a terminal device during livestreaming, then the audio playback is convenient, but the poor quality of playback devices degrades the overall audio effect
Solution Approach 1:
The patent creates a high-quality copy of the background music by recording it directly into a dedicated audio channel during the livestreaming setup, bypassing the need for real-time playback through terminal devices. This copied audio data maintains original quality without being degraded by playback device limitations, while still providing the desired background music effect.
3Manufacturing precision
If separate channels are used for recording streamer's voice and background music, then audio quality is improved, but the device complexity increases
Solution Approach 1:
The patent makes the audio processing system multi-functional by enabling it to simultaneously handle voice recording, background music recording, and audio mixing through a unified audio processing apparatus. This universal approach allows separate channel recording without proportionally increasing device complexity, as the same apparatus performs multiple audio functions.
