Title: game machine
IPC: A63F7/02
Filed: 2023-03-17
Abstract: PROBLEM TO BE SOLVED: To suppress a decrease in desire to play a game. 
     SOLUTION: When a privilege game is executed, clocking of a first performance period of a first performance or a second performance period of a second performance under execution is tentatively stopped by tentative stop means, and a tentative stop by the tentative stop means is cancelled by cancellation means based on completion of the privilege game. Even if the clocking is tentatively stopped by the tentative stop means, first performance execution means or second performance execution means is allowed to execute the first performance or the second performance by continuation means. Even if the first performance or the second performance is completed, when a remaining period of the first performance period or the second performance period exists, a specific performance is executed during the remaining period by specific performance execution means. Thus, a decrease in desire to play a game can be suppressed.

Filed: 2023-07-27
Abstract: To provide a method for applying compression to an audio signal.SOLUTION: An audio signal is compressed by using a gain factor applied in an another audio coordinate system in a prescribed audio coordinate system. A first component and a second component in a first audio coordinate system are generated from a third component and a fourth component of the audio signal in a second audio coordinate system. An amplitude threshold for defining levels for the third component and the fourth component to apply compression is determined. The gain factor for the first component is generated by using a compression ratio. When one of the third component and the fourth component exceeds the amplitude threshold, the gain factor is applied to the first component to generate the adjusted first component. A first output channel and a second output channel in the second audio coordinate system are generated by using the adjusted first component and second component in the first audio coordinate system.SELECTED DRAWING: Figure 1
