Wireless Earphone Audio Rendering for Immersive Atmos
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless earphones are unable to effectively present a high-quality surround sound and Atmos effect, failing to meet users' increasing demands for immersive audio experiences.
Innovation Solution
An audio processing method and system that involves receiving a to-be-presented audio signal from a playback device, performing rendering processing on specific audio signals, and synchronizing metadata to enhance the audio rendering, thereby enabling the wireless earphone to deliver a high-quality surround sound and Atmos effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If wireless earphones use traditional two-channel stereo sound field, then device complexity is low, but audio quality and surround sound effect are insufficient
Solution Approach 1:
The patent segments the audio processing tasks between the playback device and the wireless earphone. The playback device performs initial rendering processing on the audio signal, while the wireless earphone performs additional rendering processing on received audio signals. This segmentation allows the earphone to achieve advanced audio effects without requiring all processing capabilities to be built into a single device, thus improving audio quality while managing device complexity.
Solution Approach 2:
The playback device performs preliminary rendering processing on the audio signal before transmission to the wireless earphone. This preliminary action prepares the audio signal in advance, allowing the earphone to focus on final rendering and playback optimization, thereby achieving high-quality surround sound and Atmos effects without overburdening the earphone's processing capabilities.
2Manufacturing precision
If wireless earphones perform full rendering processing, then audio quality is improved, but energy consumption increases
Solution Approach 1:
The wireless earphone performs partial rendering processing on received audio signals rather than complete rendering from scratch. The playback device has already performed initial rendering, so the earphone only needs to perform additional rendering on the pre-processed signal. This partial action approach achieves high audio quality while reducing the energy consumption burden on the wireless earphone.
3Adaptability or versatility
If wireless earphones support surround sound and Atmos effects, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system implements multi-functionality by enabling the wireless earphone to handle both traditional stereo audio and advanced surround sound/Atmos effects through the same hardware architecture. The earphone can receive and process different types of audio signals (stereo, surround sound, Atmos) and perform appropriate rendering based on the signal type, providing universal compatibility across different audio formats without requiring separate dedicated hardware for each function.

AI summary
Provided are an audio processing method, apparatus, system and a storage medium. Firstly, a wireless earphone receives a to-be-presented audio signal sent by a playback device in a wireless transmission mode. The to-be-presented audio signal includes an audio signal that has undergone rendering processing performed the playback device, namely a first audio signal, and includes an audio signal that is to be rendered, namely a second audio signal. Then, if the to-be-presented audio signal includes the second audio signal, the wireless earphone performs rendering processing on the second audio signal, to obtain a third audio signal. Finally, the wireless earphone performs subsequent audio playing, according to the first audio signal and/or the third audio signal.
