Media File Equalizer Mapping for Cross-Device Sound Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for setting equalizers in media file reproduction require manual adjustment for each music genre and do not allow for seamless transfer of optimized settings between different digital audio devices, causing inconvenience to users.
Innovation Solution
A method and apparatus that read mapping information from a media file to search and apply a sound field effect file, which sets the equalizer based on user preferences, allowing for optimized equalizer settings to be stored and transferred between devices, including the use of a sound field effect file that can be locally stored or accessed via a URL.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual equalizer settings are used for each music genre, then the equalizer can be customized for different genres, but the user must manually set the equalizer whenever the genre changes, causing inconvenience
Solution Approach 1:
The patent applies preliminary action by pre-configuring equalizer settings for different music genres and automatically selecting the appropriate setting based on the detected genre. The system performs the equalizer configuration in advance for various genres and stores these settings, eliminating the need for manual adjustment when genre changes occur during playback.
2Reliability
If equalizer settings are device-specific, then each device can have optimized settings, but the settings cannot be transferred between devices, requiring reset on each device
Solution Approach 1:
The patent implements universality by creating equalizer settings that can be applied across multiple devices. The system generates genre-based equalizer configurations that are not tied to a specific device but can be transferred and applied universally. This allows users to maintain consistent optimized settings across different reproducing apparatuses without requiring device-specific configuration.
3Ease of operation
If generic equalizer settings are applied to all media files, then the settings are simple to implement, but the settings do not match user preferences for specific genres
Solution Approach 1:
The patent applies local quality by implementing genre-specific equalizer settings tailored to different music types. Instead of using a single generic setting for all media files, the system detects the genre of each media file and applies a customized equalizer configuration specific to that genre. This ensures optimal sound quality for each genre while maintaining automated operation.
Data Source
AI summary
A method and apparatus to reproduce a media file including reading mapping information from a predetermined position of the media file, searching for a sound field effect file of the media file by referring to the mapping information, and setting an equalizer of the audio data on the basis of the sound field effect file. A user can reproduce a media file by using an optimized equalizer of each media file even though the user himself does not set the equalizer. Also, since an equalizer setting of the reproducing apparatus can be applied to another reproducing apparatus, a user can enjoy listening to a media file in the other reproducing apparatus under the same reproducing conditions as those of the reproducing apparatus.
