Visual Audio Equalization Interface for Non-Expert Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Audio equalization technologies often confuse non-expert users with complex sliders for individual frequency band adjustments, making it difficult for them to set ideal settings for various audio recordings.
Innovation Solution
A visual user interface with first and second configurable elements allows users to intuitively establish and modify audio equalization characteristics by positioning the first element on predefined regions, providing visual feedback and a visual representation of the changes through the second element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional audio equalizers provide individual slider controls for each frequency band, then audio professionals can precisely control gain for each frequency band, but non-expert users find the interface confusing and difficult to operate
Solution Approach 1:
The patent segments the complex equalization control into two distinct interfaces: a simplified visual interface with configurable elements positioned on frequency spectrum visualizations for non-expert users, and a detailed slider-based interface for audio professionals. This segmentation allows each user type to interact with the appropriate level of complexity without being overwhelmed by the other.
Solution Approach 2:
The patent introduces an intermediary visual representation layer (frequency spectrum display with positioned configurable elements) that mediates between the user's simple positional input and the complex underlying equalization parameters. This intermediary automatically translates the position of configurable elements into appropriate frequency band gain settings, eliminating the need for users to directly manipulate individual frequency sliders.
2Measurement precision
If audio equalizers provide detailed individual controls for each frequency band, then precise audio equalization can be achieved, but the device complexity and number of controls increase
Solution Approach 1:
The patent merges multiple individual frequency band controls into a single unified visual interface where configurable elements represent the entire frequency spectrum. Instead of presenting users with dozens of individual sliders, the system combines them into a cohesive visual display where the position of configurable elements on the frequency spectrum automatically determines the equalization settings for all frequency bands.
Solution Approach 2:
The visual user interface serves multiple functions simultaneously: it displays the frequency spectrum visualization, provides intuitive positioning controls for equalization, shows real-time feedback of equalization characteristics, and automatically translates user input into precise frequency band settings. This multi-functionality eliminates the need for separate controls for each function, reducing overall interface complexity.
3Adaptability or versatility
If non-expert users are presented with complex frequency band sliders, then comprehensive control is available, but users cannot readily establish ideal settings for different audio recordings
Solution Approach 1:
The patent prepares the equalization interface by pre-organizing configurable elements on the visual display according to their corresponding frequency band positions before the user arrives. This preliminary arrangement allows users to simply position elements on the frequency spectrum without needing to understand frequency relationships, as the system has already prepared the appropriate spatial mapping. This preliminary setup enables rapid adaptation to different audio recordings without requiring users to learn complex frequency band relationships.

AI summary
A method, apparatus and computer program product are provided in order to present an intuitive visual user interface for audio equalization. In the context of a method includes defining at least two locations upon the visual user interface. Each location is associated with a predefined audio equalization characteristic. The method also causes first and second configurable elements to be provided by the visual user interface. Further, the method includes associating an audio equalization characteristic with the first configurable element based upon a location of the first configurable element relative to the at least two locations. The second configurable element provides a visual representation of the audio equalization characteristic based upon the location of the first configurable element.
