1. An audio mixing device comprising:
a gain setting circuit configured to set first to n-th gains based on a command input from the outside, n being an integer of 2 or more; and
a mixing circuit configured to output a mixing signal obtained by mixing two or more of first to n-th multiplication data obtained by respectively multiplying first to n-th audio data by the first to n-th gains,
wherein during play of j-th audio data of the first to n-th audio data with a first value set to a j-th gain of the first to n-th gains, the gain setting circuit sets the j-th gain to a second value different from the first value when the gain setting circuit receives a command to start or stop play of k-th audio data having a higher priority than the j-th audio data.
