Vinyl-Type Record Region Selection for Seamless Audio Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital audio processing systems are complex and interruptive for DJs, requiring frequent switching between devices to manage different versions of a song along a time axis, which disrupts the seamless playback experience.
Innovation Solution
A system comprising a digital audio unit and a user control device that allows seamless selection and playback of different versions of a song by partitioning a vinyl-type record into concentric regions, each associated with a specific time interval, and using a region identification signal to control the digital audio unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a DJ uses conventional digital audio processing systems to manage different versions of a song, then the system can provide multiple audio tracks and effects, but the user workflow is interrupted frequently requiring switching between devices
Solution Approach 1:
The patent combines multiple audio tracks representing different versions of a song into a single vinyl-type record. The control device integrates playback control and version selection functions, allowing the DJ to manage all audio tracks from one unified interface rather than switching between multiple devices.
Solution Approach 2:
The vinyl-type record serves multiple functions simultaneously: it stores multiple audio tracks, provides visual region indicators for different song versions, and enables direct playback control. The single control device handles both playback control and version selection, making it a multi-functional tool that eliminates the need for separate devices.
2Adaptability or versatility
If a DJ uses conventional systems with multiple control devices, then different audio functions can be controlled, but the complexity of the system increases
Solution Approach 1:
The patent merges multiple control functions into a single control device that can select between different audio tracks and control playback. Instead of requiring separate devices for playback control and version selection, the system integrates these functions into one unified interface that the DJ operates from a single location.
3Ease of operation
If a DJ uses traditional vinyl records, then intuitive hands-on operation is possible, but the availability of desired music is limited and sound quality degrades with prolonged use
Solution Approach 1:
The vinyl-type record is segmented into multiple concentric regions, each containing an audio track representing a different version of a song. This segmentation allows multiple versions to be stored on a single record while maintaining the physical, hands-on operation characteristics of traditional vinyl. The pickup device can be positioned at different regions to select different versions.
Solution Approach 2:
The system uses digital audio data stored on the vinyl-type record, which can be copied and reproduced without degradation. Unlike traditional vinyl that degrades with playback, the digital copies maintain consistent sound quality while preserving the tactile operation of moving the pickup device across different regions.
Data Source
AI summary
A system for processing digital audio signals. The system includes a digital audio unit configured to provide digital audio data of a first audio track and a second audio track. The first audio track and a second audio track represent different versions of the same piece of music. The system also includes a user control device operable by a user to allow the user to select either a first region or a second region. The digital audio unit is configured to play back audio signals obtained from the first audio track when the first region is selected, and to play back audio signals obtained from the second audio track when the second region is selected.
