Remote Audio Device Power Control for Wireless Recording Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless audio recording systems face issues with data loss due to transmission errors and interference, leading to incomplete or distorted audio recordings, as they lack effective mechanisms for real-time correction and synchronization of audio signals across multiple devices.
Innovation Solution
A system that dynamically adjusts the power levels of local audio devices through remote control units, allowing for accurate timestamping and synchronization of audio signals, enabling the correction of transmission errors by replaying missed audio segments and ensuring synchronized playback across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is used to record audio from multiple performers, then mobility and ease of operation are improved, but data loss due to transmission errors and interference occurs
Solution Approach 1:
The system performs preliminary actions by continuously monitoring transmission quality and preparing backup receiver circuits before data loss occurs. When transmission errors are detected, the system has already positioned alternative receiver circuits to immediately take over, preventing data loss without interrupting the recording process.
Solution Approach 2:
The patent introduces intermediary elements in the form of multiple redundant receiver circuits that act as mediators between the wireless transmitter and the recording system. These intermediary receivers provide alternative pathways for audio signal transmission, ensuring that data loss is prevented even when primary transmission paths are compromised by interference or errors.
2Reliability
If redundant receiver circuits are added to correct transmission errors, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple receiver circuits into a unified system with centralized control logic that automatically selects and switches between receivers. This combining approach maintains reliability through redundancy while reducing overall system complexity by sharing common components such as power supplies, signal processing circuits, and control mechanisms across multiple receiver channels.
Solution Approach 2:
The system dynamically changes operational parameters by adjusting which receiver circuit is active based on real-time transmission quality assessment. Rather than permanently configuring multiple independent receiver systems, the patent modifies the operational state of receiver circuits, switching between them as needed to correct transmission errors while maintaining a manageable device complexity.
3Manufacturing precision
If audio gain is adjusted locally at the recorder, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements universal control capabilities where the recorder can function both as a local adjustment device and a remote-controlled device. The system incorporates multi-functionality by allowing gain adjustment through multiple interfaces: local physical controls at the recorder and remote digital controls from external devices, enabling the same device to serve multiple operational needs without compromising audio quality or ease of use.
Solution Approach 2:
The system employs feedback mechanisms that allow real-time monitoring and adjustment of audio gain parameters. The recorder provides feedback about current gain settings and audio quality metrics, enabling operators to make precise adjustments either locally or remotely with immediate knowledge of the impact on audio quality. This feedback loop maintains manufacturing precision while enhancing ease of operation through informed remote control.

AI summary
Systems and methods for wirelessly recording multi-track audio files. In some aspects, each performer is equipped with a local audio device capable of locally recording the respective performer's audio while also transmitting it to a master recorder. Functions of the local audio device may be adjusted remotely. The locally recorded audio may be used to repair or replace any audio lost or corrupted during transmission to the master recorder. Such repair or replacement may be performed electronically or via playback of the locally recorded audio. In other aspects, a master recorder is not required since all locally recorded audio may be combined or otherwise processed post-recording. Locally recorded audio may include identifiers to aid in post-recording identification of such audio. A multi-memory unit is provided to facilitate manipulation and processing of audio files. A method for automatically adjusting local audio device power mode based upon recorder status is also disclosed.
