Multi-Track Recording System Using Provisional Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording systems for group music performances, such as brass bands or singing groups, are inefficient in recording individual performance tracks, requiring extensive time and labor to set up equipment and integrate sound data from multiple devices.
Innovation Solution
A recording system comprising a management device and terminal devices that allow simultaneous recording across multiple tracks, with provisional segment creation, data acquisition, and conversion to actual segments, enabling easy multi-track recording of entire group performances without the need for extensive setup or data integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dedicated equipment such as multiple microphones and multi-track recorders are used to record separate tracks for each player or performance part, then multi-track recording capability is achieved, but device complexity and setup time increase significantly
Solution Approach 1:
The patent applies universality by enabling ordinary portable terminal devices (smartphones, tablets) to perform multi-track recording functions. Instead of requiring dedicated recording equipment, the system allows any terminal device with recording capability to contribute to multi-track recording through network connectivity, making the system universally applicable with existing devices
Solution Approach 2:
The patent merges multiple independent recording functions into a unified networked system. Multiple terminal devices that independently record sound are combined through network communication to create integrated multi-track recordings, merging individual recording capabilities into a coordinated multi-track system
2Adaptability or versatility
If multiple microphones and multi-track recorders are deployed for separate track recording, then sound separation by player or performance part is achieved, but time and labor required for wiring and settings increase
Solution Approach 1:
The patent replaces the mechanical system of physical microphone wiring and connector setup with wireless network communication. Instead of physically connecting multiple microphones to a recorder through cables, the system uses network protocols to transmit and synchronize audio data, eliminating the need for manual wiring and physical setup
Solution Approach 2:
The system enables terminal devices to automatically manage their own recording operations and data transmission. Each device independently records sound, automatically transmits data through the network, and synchronizes with the system without requiring manual configuration or intervention, reducing setup time and operational complexity
3Adaptability or versatility
If multiple independent recorders are used to record player-specific sounds separately, then individual track recording is achieved, but difficulty in integrating sound data from individual recorders increases
Solution Approach 1:
The patent introduces a management server as an intermediary that coordinates between multiple terminal devices. The server receives recording data from various devices, manages synchronization, and handles the integration process, thereby simplifying the complexity of combining data from multiple independent recorders through a centralized coordination point
Solution Approach 2:
The system performs preliminary actions by pre-establishing device identification, track assignment, and synchronization protocols before recording begins. Terminal devices are pre-configured with their roles and data transmission parameters, so that when recording starts, data integration is already structured and organized, reducing post-recording integration complexity
Data Source
AI summary
A management device has a plurality of tracks (MTR) corresponding to a plurality of terminal devices, commands the terminal devices to start/stop recording in response to recording start/stop instructions (recording command circuitry), and creates, in each of the tracks, a provisional segment identifying a recording time corresponding to the instructions (provisional segment creation circuitry). Each of the terminal devices records sound data in response to the recording start/stop instructions (recording circuitry) and transfers the recorded sound data to the management device (transfer circuitry). The management device 10 acquires the sound data from the individual terminal devices (acquisition circuitry), and then the management device records the acquired sound data in association with the provisional segments of the corresponding tracks and thereby converts the provisional segments into actual segments (conversion circuitry).
