Wagering Game Audio Key Synchronization via Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In traditional wagering game machines, the credit bang-up sound often clashes harmonically with the bonus game soundtrack, especially when it changes tonality or key, leading to an unpleasing experience for players, as existing solutions either restrict the sound to non-pitched instruments or specific tonal areas, lacking flexibility and failing to address harmonic clashes.
Innovation Solution
The use of audio markers to denote the state of a music file, allowing the credit bang-up sound to end in the same key as the continuous bonus game music, ensuring synchronization and harmonization through programmatically controlled volume adjustments and timing markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the credit bang-up sound uses pitched instruments with varying tonality, then the entertainment value and creative composition options are improved, but harmonic clashes with the bonus game soundtrack occur
Solution Approach 1:
The system dynamically adjusts the key of the credit bang-up sound to match the current key of the bonus game soundtrack. The audio marker file continuously tracks the musical state and programmatically changes the playback key of the bang-up sound to harmonize with the evolving soundtrack, transforming a static audio approach into a dynamic adaptive system.
Solution Approach 2:
The invention changes the musical parameter (key) of the credit bang-up sound in real-time based on the state of the bonus game soundtrack. By programmatically adjusting the playback key parameter to match audio markers in the soundtrack, the system maintains harmonic compatibility while preserving the use of pitched instruments with varying tonality.
2Object-affected harmful factors
If the credit bang-up sound is restricted to non-pitched instruments or specific tonal areas, then harmonic clashes are reduced, but the entertainment value and creative composition options are reduced
Solution Approach 1:
The system transforms the static restriction approach into a dynamic adaptive approach. Instead of limiting the bang-up sound to specific tonal areas, the system dynamically tracks the soundtrack's key through audio markers and adjusts the bang-up sound's playback key in real-time, enabling full creative freedom without harmonic clashes.
Solution Approach 2:
The invention implements a feedback mechanism where the audio marker file continuously monitors the bonus game soundtrack's musical state and feeds this information back to the audio playback system. This feedback loop enables the bang-up sound to automatically adjust its key to match the soundtrack, eliminating the need for restrictive tonal areas while maintaining harmonic compatibility.
3Device complexity
If the credit bang-up sound plays independently without synchronization, then the implementation is simple, but the harmonic compatibility with changing bonus game music is poor
Solution Approach 1:
The invention introduces an audio marker file as an intermediary between the bonus game soundtrack and the credit bang-up sound. This marker file contains embedded key information that mediates the interaction between the two audio elements, enabling automatic harmonic synchronization without complex real-time analysis or manual arrangement.

AI summary
In a wagering game machine, operations and systems are disclosed for ending wagering game audio in a key of the current state. In one embodiment, the use of markers to denote the state of a music file enables following the continuous music and ending wagering game bang-up audio in whatever key the continuous music is in at the precise moment the bang-up ends. The continuous music, bang-ups and marker file are all started at the same time and may be the same length. The continuous music is audible, the bang-ups are heard by raising the volume when programmatically called for, and the marker file continuously sends out signals at a set rate which the code then interprets to determine the state of the song to trigger the appropriate musical ending. When the bang-up ends it can then be played in the key corresponding to the current state of the music.
