Abstract: An audio apparatus according to an embodiment includes an audio signal receiving unit, a music gap signal receiving unit, a playback unit, and a determining unit. The audio signal receiving unit receives an audio signal in which successive multiple music data are contained in a single block of data. The determining unit determines a boundary of the music data on the basis of the time at which the music gap signal that indicates the boundary of the music data by the music gap signal receiving unit and the duration of a silent period in the audio signal that is played back by the playback unit.

Abstract: There is provided an in-vehicle display apparatus including a display unit that displays different images to be seen from a driver's seat side and a passenger's seat side; and an image control unit that causes the driver's seat side to display a navigation image, when operation mode is switched from a second operation mode in which an operation on a second image displayed on the passenger's seat side is allowed, to a first operation mode in which an operation on a first image displayed on the driver's seat side is allowed.

Abstract: Sound equipment is configured to average an average value of a signal level at each predetermined frequency band of a sound signal at a different averaging time, to weight the average value calculated at a different averaging time by using an individual weighting value, to obtain a representative value based on a weighted average value, to determine a gain of a sound signal based on an obtained representative value, to correct a volume based on the corresponding gain, and to correct a volume based on the gain. The representative value is obtained by selecting the average value at which a gain becomes minimum within each weighted average value. The averaging performs at least a first averaging using the averaging time corresponding to the sound signal that the signal level changes rapidly, and a second averaging using the averaging time longer than the averaging time of the first averaging.

Abstract: A DSP performs a sound volume adjustment processing that adjusts a playback sound volume in accordance with a signal level of acoustic data in acoustic contents. Further, when the DSP detects that the acoustic data is switched, the DSP initializes the adjustment to perform a reset processing that performs adjustment in accordance with the acoustic data which is a new playback target. When the changing instruction of the playback position of the acoustic data is accepted, an audio microcomputer instructs the DSP to perform the reset processing.
