Live Event Audio Sync for High-Fidelity Audience Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld audio-visual recording devices often produce low fidelity audio signals that fail to capture the sound quality of live events effectively due to limitations in integrated microphones and ambient noise, which detracts from the appreciation of artistic or oratory performances.
Innovation Solution
A system for real-time wireless synchronization of high quality audio segments with video recordings using sound board equipment and broadcasting devices, allowing high fidelity audio to be transmitted to reception devices, which can then synchronize with video segments recorded by audience members, using A-V Synchronization Application on computing devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If integrated microphones are used in handheld AV recording devices, then the device can record audio, but the sound quality is low and insufficient for live events
Solution Approach 1:
The patent combines multiple audio sources (integrated microphone and external wireless microphone) into a single audio recording system, allowing the device to switch between or combine audio inputs to achieve high fidelity recording while maintaining manageable device complexity
Solution Approach 2:
The patent introduces a wireless microphone system as an intermediary device that captures high quality audio separately and transmits it to the handheld recording device, thereby achieving high audio fidelity without requiring the handheld device itself to have complex high-fidelity microphone hardware
2Adaptability or versatility
If handheld AV recording devices are positioned far from the performance, then the device can capture the overall event, but the audio quality deteriorates
Solution Approach 1:
The wireless microphone acts as an intermediary that bridges the gap between the performance and the handheld recording device, allowing the device to be positioned anywhere in the venue while maintaining high audio quality through wireless transmission from the microphone near the performance
Solution Approach 2:
The patent segments the audio capture function from the video recording function by using separate wireless microphones for audio and handheld devices for video, allowing each to be optimally positioned and configured independently
3Measurement precision
If audio is recorded separately from video, then high fidelity audio can be captured, but synchronization between audio and video becomes complex
Solution Approach 1:
The patent implements feedback mechanisms where the handheld recording device receives and processes wireless audio signals, automatically synchronizing them with video recording through timestamp correlation and buffer management, thereby reducing manual synchronization complexity
Solution Approach 2:
The wireless audio transmission system serves as an intermediary that carries both audio data and synchronization timestamps, allowing the handheld device to automatically align audio with video without requiring complex manual synchronization procedures

AI summary
Systems and methods are presented herein that facilitate temporally synchronizing, in real time, a separately sourced high quality audio segment of a live event with a video segment that is generated by a recording device associated with a member of the audience. An A-V Synchronization Application may synchronize a video segment of a live event that is generated from a personal electronic device of an audience member with a high quality audio segment that is separately sourced and generated by professional sound recording equipment at the live event. The result of the temporal synchronization is a high fidelity digital audio visual recording of the live event. In various, the audience member may stream, in real-time, the high fidelity digital audio visual recording to an additional electronic device at a different geo-location. In some examples, narrative audio segments may be also included as part of the high fidelity digital audio visual recording.
