Computer-Implemented Audio Adjustment Method and Audio Adjustment Apparatus

An audio adjustment apparatus comprising:

• at least one memory configured to store instructions;
• and
• at least one processor configured to execute the instructions to:
• cause N sound characteristics to be in one-to-one correspondence with N specific points included in an operation area for sound characteristic adjustment, where N is a natural number greater than or equal to three;
• receive an operation to specify, as a selected point, a freely selected location within the operation area;
• identify, as a selected characteristic, a sound characteristic corresponding to the selected point based on at least one specific point among the N specific points, at least one sound characteristic corresponding to the at least one specific point, and the selected point;
• determine whether the selected characteristic is to be a target sound characteristic that is set by the sound characteristic adjustment;
• execute, in response to the selected characteristic not being determined to be the target sound characteristic, and based on the selected characteristic and the N sound characteristics, updating processing to update at least one of the N sound characteristics to at least one sound characteristic other than the N sound characteristics;
• and
• receive the operation again in response to the selected characteristic not being determined to be the target sound characteristic.
