Vinyl Record Audio Display for Track Boundary Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for displaying and editing audio data, especially from analog vinyl records, face challenges in accurately identifying track boundaries due to obscuration by higher amplitude signals and residual background noise, making it difficult to establish precise track marks visually.
Innovation Solution
A system that converts audio data into a visual representation emulating a vinyl record format, using a spiral radial paradigm with arc segments and visual identifiers to represent audio parameters, allowing users to interactively manipulate the playback position and refine editing by simulating the tactile experience of a vinyl record player.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a rectilinear waveform display is used to show audio amplitude and time offset, then technical information about the audio is displayed, but track boundary identification becomes difficult due to obscuration by higher amplitude signals
Solution Approach 1:
The patent transforms the traditional rectilinear waveform display into a circular/vinyl record format where track boundaries are represented as radial positions. This dimensional change from linear to circular space allows track boundaries to be visually distinguished as specific radial locations rather than being obscured by amplitude variations in a linear waveform, thereby resolving the information loss and detection difficulty.
2Difficulty of detecting and measuring
If zooming in on a smaller portion of the waveform is performed to visualize lower amplitude audio at track boundaries, then track boundary visualization improves, but the overall overview is lost and tedious scrolling is required
Solution Approach 1:
The patent merges the overview and detailed view functions into a single circular display. The entire audio recording is represented in the circular format, allowing users to see the complete structure at once while track boundaries remain clearly visible as specific radial positions. This eliminates the need to scroll between zoomed views, combining the benefits of both overview and detailed inspection in one visualization.
3Ease of operation
If traditional waveform display is used for analog transcriptions with background noise, then audio playback is possible, but accurate track mark point establishment becomes impossible due to residual noise obscuring quiet parts
Solution Approach 1:
The patent applies visual enhancement techniques where different regions of the circular display are highlighted or colored based on their characteristics. Track boundary regions can be visually distinguished through color coding or highlighting, allowing users to identify track marks even in the presence of background noise. This visual differentiation compensates for the lack of digital silence in analog transcriptions.
Data Source
AI summary
A method and system including segmenting digital samples related to input audio data into arc segments representing output audio data. The arc segments are arranged to form multiple arcs which are arranged to form a record image. A user-selected boundary of a track of the input audio data may be marked based on a command received from a user via an interaction with the record image.
