Binaural Earbud Audio Sync for Multi-Camera Recording
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in distinguishing and recording audio separately for multiple cameras, leading to imbalanced audio levels and degraded quality when using binaural wireless audio devices for video recording.
Innovation Solution
The electronic device establishes separate communication links with both earbuds of a binaural wireless audio device through Bluetooth, allowing simultaneous recording of audio data from each earbud synchronized with images from different cameras, enabling synchronized audio and video storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device uses only its own microphone to record audio during multiple camera recording, then the recording process is simple, but the audio quality is degraded and audio levels become imbalanced
Solution Approach 1:
The patent combines the electronic device's microphone with external earbud microphones to create a unified recording system. The processor receives audio data from both the device's microphone and the earbuds' microphones, merging multiple audio sources to achieve balanced and high-quality audio recording that corresponds to multiple camera inputs.
2Reliability
If the electronic device receives audio data from only the primary earbud, then the connection is simple, but the audio quality is degraded
Solution Approach 1:
The patent segments the audio recording function by establishing separate communication links with both the primary earbud and the secondary earbud. Each earbud's microphone data is received through its own communication link, allowing the system to process and combine audio from both sides independently, thereby improving audio quality while maintaining manageable connection complexity.
3Ease of operation
If the electronic device records audio for multiple cameras using a single microphone, then the setup is simple, but the audio levels from different speakers become imbalanced
Solution Approach 1:
The patent applies local quality by assigning different audio sources to different camera inputs. The processor receives audio data from the device's microphone and from each earbud's microphone separately, enabling localized audio optimization where each camera's audio level can be independently adjusted based on its corresponding microphone source, achieving balanced audio levels across multiple speakers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach ensures balanced audio levels and improved quality by separately recording audio from each earbud, enhancing the overall audio-visual experience during multiple camera recording.
Implementation Method 1
establishing a first communication link and a second communication link for supporting binaural recording with a first earbud and a second earbud included in the external electronic device, respectively, through the communication circuit

AI summary
A processor included in an electronic device may be configured to: display an audio input selection screen related to a plurality of audio inputs in a multiple camera recording mode; receive a first user input for selecting an external electronic device through the audio input selection screen; in response to the first user input, establish, through a communication circuit, each of first and second communication links for supporting first and second ear buds included in the external electronic device and binaural recording; while recording is performed by simultaneously using first and second cameras, receive first and second audio data obtained from the first and second ear buds through the first and second communication links, respectively; and store first and second images obtained from the first and second cameras in synchronization with the first and second audio data.
