1. An audio signal processing device, comprising:
an audio signal analysis unit configured to acquire an audio signal, and configured to set a target value for an audio adjustment based on the audio signal;
an orientation variation analysis unit configured to acquire orientation information, and configured to generate an orientation variation amount based on the orientation information; and
an audio signal adjustment unit configured to adjust the audio signal toward the target value based on the orientation variation amount,
wherein the audio signal adjustment unit is configured to adjust the audio signal to lower a volume of the audio signal based on a determination that the orientation variation amount becomes larger than a first threshold value, and
based on a determination that the audio signal reaches the target value, and the orientation variation amount becomes smaller than a second threshold value, the audio signal adjustment unit is configured to adjust the audio signal to return the volume of the audio signal.
