A wireless communication device and a wireless communication method are provided. When a master mode is set in a mode memory, a mode setting notification is transmitted to a different wireless communication device. When a mode setting permission notification for the mode setting notification is received from the different wireless communication device, the master mode is settled as a communication mode, and the master mode is set in the mode memory. When a slave mode is set in the mode memory and when a mode setting notification is received from the different wireless communication device, the slave mode is settled as the communication mode, the slave mode is set in the mode memory, and a mode setting permission notification is transmitted to the different wireless communication device. Thus, the communication mode can be automatically set in a pair of wireless communication devices.

A wireless communication device and a wireless communication method capable of curbing occurrence of latency even when performing wireless communication at predetermined time intervals are provided. MIDI data is transmitted and received by communication (B) performed through a wireless module during an intermission between communications (A) performed at predetermined time intervals through the wireless module. Accordingly, a communication speed for wireless communication is improved. Therefore, compared to a case in which wireless communication is performed by only the communication (A), MIDI data can be quickly transmitted and received, and thus occurrence of latency can be curbed.

A method for constructing an adaptive media file comprising a plurality of audio components configured to be used to form an audio output arranged to have a controllable tempo, the method comprising providing first audio data associated with a first audio component of the plurality of audio components, setting a playback tempo range of the first audio data, providing second audio data associated with the first audio component, setting a playback tempo range of the second audio data, wherein the tempo range of the second audio data is different to the tempo range of the first audio data, and associating the first audio data, the second audio data and the respective playback tempo ranges.

A method for constructing an adaptive media file comprising a plurality of audio components configured to be used to form an audio output arranged to have a controllable tempo, the method comprising providing first audio data associated with a first audio component of the plurality of audio components, setting a playback tempo range of the first audio data, providing second audio data associated with the first audio component, setting a playback tempo range of the second audio data, wherein the tempo range of the second audio data is different to the tempo range of the first audio data, and associating the first audio data, the second audio data and the respective playback tempo ranges.

This information processing device comprises: a control unit which receives an input of information indicating one or more timings in a playback time of a piece of music, and generates a file including information pertaining to a timbre control performed from each of the one or more timings; and a transmission unit which transmits an audio signal of the piece of music and the information pertaining to the timbre control in the file to a device which outputs a synthesized sound of the playback sound of the piece of music and the playing sound of a musical instrument.

A new interface is provided that supports simultaneous transmission of an audio signal and a MIDI signal. Signals consecutive in predetermined units are transmitted to a reception side via a predetermined transmission path. The signals consecutive in the predetermined units include a signal of a first predetermined unit of the predetermined units including an audio signal and a signal of a second predetermined unit of the predetermined units including a MIDI signal. For example, the audio signal is a linear PCM signal constituting a stereo 2-channel audio signal. For example, the MIDI signal includes packet data of a predetermined length, and the packet data of the predetermined length is divided into a plurality of pieces, and transmitted by being included in signals of a plurality of pieces of the second predetermined units.

An electronic musical instrument includes; a plurality of keys, each of the plurality of keys specifying a pitch; a memory storing musical piece data representing a musical piece; and a processor, wherein the processor executes the following: retrieving the musical piece data of a musical piece from the memory and determining whether the musical piece data contains data of a lyric; and when the musical piece data contains the data of the lyric, and if a note specified by an operation of a key by a user is accompanied by a part of the lyric in the musical piece, causing data of a singing voice sound having the pitch specified by said operated key to be generated in accordance with the part of the lyric in response to the operation of the key, and causing the singing voice sound to be audibly output.
