Then, an output characteristic suitable for the identified usage environment is selected, and the selected output characteristic is set as an output characteristic of music data to be output from the wireless speaker (1). In this case, a ratio between a width of a wall behind the wireless speaker (1) and a width of the speaker is obtained from the picked-up image data obtained by picking up an image of the installation room of the wireless speaker (1) so that boundaries between the wall behind the wireless speaker (1) and both sides thereof are aligned with both edges of an angle of view, and a size of the installation room of the wireless speaker (1) is identified based on this ratio to be used as the usage environment. Further, an installation position of the speaker is identified based on a display position of the speaker in the picked-up image data to be also used as the usage environment. ## Claims ### Claim 1 A program readable by a computer, for causing the computer to function as an audio controller, the program stored on a non-volatile memory comprising: output characteristic storage means for storing an output characteristic of a playback signal for each usage environment of a speaker;
