A video playback apparatus includes a processor configured to set a parameter related to a playback state of a first video, and control a playback state of a second video different from the first video in a display mode including a mode in which the first video and the second video are simultaneously displayed based on setting of the parameter, wherein playback timings of the first video and the second video are identified by time codes of the same music.

A data processing device including: a first audio analyzer that extracts, from audio data of a music piece including a first part and a second part that are acoustically separable from each other, audio data of the first part; a second audio analyzer that generates, from the audio data of the music piece, data of a unit sound of the second part; a third audio analyzer that generates, from the audio data of the music piece, data indicating a sounding position of the second part; a master tempo processor that performs master tempo processing on audio data including at least the first part; and a mixing processor that generates audio data in which the audio data of the first part subjected to the master tempo processing is mixed with audio data of the second part, the audio data of the second part being configured by relocating a sound of the second part.

A playing controller includes: a data acquiring unit configured to acquire audio data associated with information regarding a play position in a music piece and text-related data associated with the information regarding the play position; an operation signal acquiring unit configured to acquire an operation signal indicating an operation for a control of the music piece; an audio data processing unit configured to process, in accordance with the operation signal, the audio data associated with a section within the music piece identified by the information regarding the play position; an image data generating unit configured to generate image data containing a character image based on the text-related data and process the character image showing a lyric in the section based on the information regarding the play position and the operation signal; and a data output unit configured to output the processed audio data and the image data.

An audio data processing device is provided including a player configured to play an audio data, a playing direction switcher configured to switch a playing direction of the audio data between a forward direction and a reverse direction in response to an operation signal, and a play effect selector configured to apply a first play effect to the audio data when the playing direction is the forward direction and configured to apply a second play effect different from the first play effect to the audio data when the playing direction is the reverse direction.

An information processing device includes a determining section configured to check first authentication information based on a user input against second authentication information received from DJ equipment and including operation information for the DJ equipment, and to perform user authentication based on a matching result.

Provided is an audio device for performing control related to a separation process of separating audio data of a music piece into multiple parts, the multiple parts being included in the music piece, the audio device including: a display controlling module configured to cause a display to display labels representing the respective multiple parts; an operation acquiring module configured to acquire information indicating a user operation of selecting at least a portion of the labels; and a selecting module configured to select at least one part included in the multiple parts based on the information indicating the user operation.

A sound control device configured to mix a first music piece and a second music piece includes: a comparing section configured compare a BPM of the first music piece and a BPM of the second music piece; and an effect selecting section configured to select a sound effect according to a result of the comparison.

An acoustic control device for mixing a first music piece and a second music piece is configured to switch a magnitude relationship between a volume of the first music piece in a low-frequency band and a volume of the second music piece in a low-frequency band by lowering the volume level of the first music piece in the low-frequency band and raising the volume level of the second music piece in the low-frequency band in accordance with an operation of an operator for controlling the volume of the first music piece and the volume of the second music piece.

A rotary operator includes: a rotator including a movement path provided for an outer circumferential surface and inclined to a circumferential direction about a rotation axis, the rotator rotating about the axis; and a contact piece coming into contact with the rotator, and moving along the path in a direction along the axis in association with rotation of the rotator. Rotation of the rotator in a first rotation direction is restricted by the contact piece being at a first position when the rotator reaches a predetermined position. When rotating force applied to the rotator is reduced in a state where rotation of the rotator in the first rotation direction from the predetermined position is restricted, the contact piece returns to a second position to allow the rotation of the rotator in the first rotation direction from the predetermined position.
