Game Music Playback Volume Control for Menu Hierarchy Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game music playback techniques fail to maintain appropriate volume levels by simply increasing the number of performance parts, leading to discomfort for users when switching between menu hierarchies, and require complex processes to manage playback positions and added performance parts.
Innovation Solution
A game device with a music storage unit, playback unit, and switch unit that simultaneously plays multiple versions of the same music track with varying numbers of performance parts, adjusting volume levels to maintain a consistent listening experience by turning down or up volumes based on user input, allowing seamless transitions between menu hierarchies without sudden volume changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of performance parts is increased to diversify music, then the music becomes more rich and diverse, but the volume control becomes complex and cannot maintain appropriate volume levels
Solution Approach 1:
The music track is segmented into multiple performance parts (first performance part, second performance part, etc.), each with independent volume control. This allows the system to manage the complexity of multiple performance parts by treating them as separate controllable units, resolving the contradiction between music diversity and volume control complexity.
Solution Approach 2:
The volume of each performance part is dynamically adjusted based on the current menu hierarchy level. When switching between menu screens, the system dynamically turns down the volume of the current performance part and turns up the volume of the next performance part, maintaining appropriate volume levels while enabling music diversity across different menu hierarchies.
2Adaptability or versatility
If multiple performance parts are played back simultaneously with different volume levels, then music diversity is achieved, but sudden volume changes occur when switching between menu hierarchies
Solution Approach 1:
The system performs preliminary actions by turning down the volume of the current performance part before switching to the next performance part. This preliminary volume adjustment prevents sudden volume changes and ensures a smooth transition, maintaining user comfort while achieving music diversity across menu hierarchies.
Solution Approach 2:
The volume adjustment process is designed to be continuous rather than abrupt. The system maintains continuous music playback while smoothly transitioning between performance parts through gradual volume changes, ensuring the useful action of music playback continues without interruption or sudden changes that would discomfort the user.
3Adaptability or versatility
If the number of performance parts is increased to distinguish menu hierarchies, then menu hierarchy distinction is improved, but the processing load and resource usage increase
Solution Approach 1:
Different performance parts are assigned to different menu hierarchy levels, with each level having its own optimized performance part configuration. This local quality approach allows the system to distinguish menu hierarchies effectively while managing processing resources efficiently by not loading all performance parts simultaneously at full quality levels.
Solution Approach 2:
When switching between menu hierarchies, the system discards (turns down) the current performance part and recovers (turns up) the next performance part. This approach allows the system to manage multiple performance parts without maintaining all of them at full processing intensity simultaneously, reducing overall resource usage while maintaining the ability to distinguish menu hierarchies.

AI summary
According to the present invention, in response to the change of the menu hierarchy, it is possible to diversify the BGM easily. First, BGM 1, BGM 2, and BGM 3 (hereinafter the BGM 1, 2, and 3) that are the same piece of music performed with different sounds are played back simultaneously. Only the volume of the BGM 1 is turned up and the volume of the BGM 2 and 3 are turned down to mute. Next, in response to the change of the menu hierarchy, the volume of the BGM 1 is muted and the volume of one of the muted BGM 2 or 3 is turned up.
