Audio Data Selection System with Automatic Time Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio data visualization tools require users to manually drag selection regions over time, which can be cumbersome and imprecise, especially when selecting specific features like frequencies or pan positions.
Innovation Solution
A method and system that allow users to select a range of audio data features and automatically extend this selection in the time domain, ignoring any time component input, enabling precise selection and editing operations without the need for extensive dragging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually drag selection regions over time to select audio features, then they can specify both feature range and time range, but the operation becomes cumbersome and imprecise
Solution Approach 1:
The selection process is segmented into two independent operations: first selecting the feature range (frequency, pan position, etc.) without time constraint, then automatically extending the selection across the desired time period. This separates the complex two-dimensional selection into simpler sequential steps, improving precision while reducing operational complexity.
Solution Approach 2:
The system performs preliminary automatic extension of the selection to cover the entire time duration or specified time range before the user completes their selection. This preliminary action eliminates the need for users to manually drag across time, allowing them to focus solely on selecting the precise feature range they need.
2Productivity
If users manually drag selection regions across the entire time duration to select specific features, then they can apply edits to the selected features across time, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system automatically extends the selection across the entire time duration or specified time range as a preliminary action immediately after the user defines their feature range. This eliminates the time-consuming manual dragging process while ensuring the selection is ready for immediate editing operations, significantly improving productivity.
Solution Approach 2:
The system performs the time-extension selection automatically without requiring user intervention. Once the user specifies the feature range, the system self-services by extending the selection across time and preparing it for editing, reducing both selection time and operational complexity.
3Measurement precision
If the selection tool responds to both feature and time input, then users have full control over selection regions, but it becomes difficult to make precise feature selections without accidental time constraints
Solution Approach 1:
The selection functionality is segmented into feature-axis selection and time-axis extension as separate operations. The selection tool is configured to respond only to feature-axis input during the selection phase, while time-axis extension is handled automatically afterward. This segmentation maintains selection flexibility while achieving feature selection precision without accidental time constraints.
Solution Approach 2:
Instead of having the selection tool respond to both feature and time input simultaneously, the system inverts the approach: the tool responds only to feature input, and the time dimension is added automatically in reverse fashion. This inversion ensures precise feature selection while maintaining versatility through automatic time extension options.

AI summary
Systems, methods, and computer program products for graphically displaying audio data are provided. In some implementations, a method is provided. The method includes displaying a graphical visual representation of digital audio data, the representation displaying a feature of the audio data on a feature axis with respect to time on a time axis. The method also includes receiving an input in the graphical visual representation selecting a range with respect to the feature and automatically extending the selected range with respect to time to define a selected region of the visual representation, where the extended range with respect to time is predefined and ignoring any component of the received input with respect to time.
