A method and a system for synthesizing beat sound and music. The method comprises: selecting a sound material as a beat sound (S101); intelligently or manually regulating, according to a human body characteristic parameter, a beat sound frequency matched with the human body characteristic parameter (S102); selecting music (S103); and synthesizing the beat sound and the music in a volume ratio to obtain mixed music (S104). The method and system for synthesizing beat sound and music provided by the present disclosure can intelligently or manually regulate the beat sound frequency and the volume ratio of the beat sound and the music through human body characteristic parameter, and obtain the mixed music in various synthesis ways. The mixed music can be used in trainings for physical and mental relaxations and improving the concentration of the human body, and is suitable for practices of improving sleeping conditions of the human body, and improving practice effects of yoga, meditation, and zazen.

A method for flattening power of a musical sound signal, said method being characterized by comprising: determining second values corresponding to respective first values indicating power at a plurality of time points of a musical sound signal each on the basis of the result of a comparison between the present value of the first value and the present value of the second value; and flattening the plurality of first values using the second values corresponding to the plurality of first values, respectively, wherein the second value changes while drawing a predetermined trajectory when, in the result of the comparison, a state where the present value of the second value is larger than the present value of the first value continues.

Disclosed is a method of providing a music creation interface using a head-mounted device, including displaying first and second geometric loops fixed relative to a location in the real world, the first and second geometric loops each including a plurality of beat indicators. The second geometric loop is spaced apart from the first geometric loop. An interface comprising a plurality of sound or note icons is displayed, and in response to receiving user selection to move a selected sound or note icon to a particular beat indicator on one of the geometric loops, the selected sound or note icon is displayed at the particular beat indicator. In use, the geometric loops are rotated relative to at least one play indicator, and the selected sound or note icon is rendered when it reaches the at least one play indicator.

Disclosed is a system and method that allows users to customize audible and visible signals, such as music or video, to maintain a pre-determined or specified pace or to achieve a new pace in repetitive motion activities such as, but not limited to, running, walking, swimming, cycling, aerobics, and the like. Other applications of the system and method include, but are not limited to, enhancing the results of medical rehabilitation programs, physical therapy, weight loss programs, disc jockey services, and industries or manufacturing settings where repetitive motion is common and where audible cues designed to help users maintain a consistent pace are useful.

There is provided an apparatus configured to control a plurality of light emitting elements so that the light emitting elements display a lighting behavior based on audio output which is based on an audio file. The apparatus can include a control portion and a choreography portion. The control portion is operable to generate an instruction sequence which can be used to control the lighting behavior of the light emitting elements, the instruction sequence can include a plurality of lighting instructions. The choreography portion is operable to associate at least one lighting instruction from the plurality of lighting instructions with at least one portion of the audio file.

Provided is a sound reproduction device including: speakers; light emitting elements provided to a part of each of the speakers, or in a vicinity of each of the speakers; a detecting section configured to detect a beat of an audio signal reproduced by the speakers, and output a detection signal corresponding to the beat; and a light emission control signal outputting section configured to output a light emission control signal for controlling a light emission mode of the light emitting elements according to the detection signal. The light emission control signal outputting section outputs a first light emission control signal according to the detection signal, and outputs a second light emission control signal when a period in which the beat is not detected exceeds a set period, the second light emission control signal being for controlling the light emitting elements to perform a predetermined light emission mode.

An electronic apparatus includes a plurality of pads, each of the plurality of pads including a touch sensor and an acceleration sensor, a sound output interface configured to output sounds that are set to the respective pads, a display configured to display visual feedback, and a processor configured to, in response to the touch sensor in a pad among the plurality of pads detecting a touch of the pad, and the acceleration sensor in the pad detecting an intensity of the touch that is greater than or equal to a value, determine that a beat is performed on the pad, control the sound output interface to output a sound that is set to the pad on which the beat is determined to be performed, with a magnitude corresponding to an intensity of the beat, and control the display to display the visual feedback corresponding to the beat determined to be performed.
