Abstract
An audio mixing device includes 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 two 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. In a case where the j-th gain of the first to n-th gains is set to a first value, when the j-th gain is to be set to a second value different from the first value, the gain setting circuit transitions the j-th gain from the first value to the second value in a stepwise manner in a j-th gain change section of first to n-th gain change sections.
