The present disclosure relates to systems, methods, and devices for music simulation. The methods may include determining one or more simulation actions based on data associated with one or more simulation actions acquired by at least one sensor. The methods may further include determining, based on at least one of the one or more simulation actions and a mapping relationship between simulation actions and corresponding musical instruments, a simulation musical instrument that matches with the one or more simulation actions. The methods may further include determining, based on the one or more simulation actions, one or more first features associated with the simulation musical instrument. The methods may further include playing music based on the one or more first features.

A device, method, and medium for integrating monaural and binaural beats into music are provided. The music is analyzed to determine key, root tone, and spectral range. It is then remixed with monaural beats and/or binaural beats at frequencies based on a desired entrainment frequency and the root tone and lowest dominant frequency range of the music. Additional harmonics of the beats in higher octaves may be integrated into the music as well using mixing and/or equalization.

Provided is a control device which controls an electronic musical instrument, comprising: an acquisition means which understands the intention of an utterance of a user on the basis of the utterance, and acquires from a dialogue engine that generates first data in which the intention is stated, the first data generated in response to the utterance; a storage means which stores conversion data in which the first data and a control command for controlling the electronic musical instrument are associated with each other; and a conversion means which generates, on the basis of the acquired first data and the conversion data, second data suitable for a control interface of the electronic musical instrument to be controlled, and transmits the second data to the electronic musical instrument.

Methods and digital circuits provide frequency correction to frequency synthesizers. Dual switched-capacitor voltage detectors connected to an input signal periodically sample the voltage of the input signal, and then determine a fundamental frequency of the input signal from the output of the dual switched-capacitor voltage detectors. The sample period of the dual switched-capacitor voltage detectors is proportional to a time period between a previous pair of voltage peaks detected in the input signal, thereby eliminating harmonic components in the original signal which might otherwise cause errors in frequency estimation without causing unwanted sluggishness in the transient response of the frequency detection process. The time period between the previous pair of detected voltage peaks is used to create a decay signal that initiates a capacitor decay time for each voltage detector. Two additional digital methods of extracting the fundamental frequency as well as an envelope of an analog audio signal are also described, one utilizing a sliding sample rate, and the other utilizing a fixed sample rate.

This disclosure relates to a cooling system for an elevator with electronic visual displays, and a corresponding method. An example system includes an elevator car having an inner wall, and an electronic visual display mounted to the inner wall so as to define a gap between the inner wall and the electronic visual display. Further, fluid is configured to flow through the gap to cool the electronic visual display.

The housing has a cover member and a body member, the cover member pivotally coupled to the body member, wherein the body member has a void dimensioned and shaped to encase a musical instrument. The audio amplification unit is configured to amplify signals received from the musical instrument, the amplification unit housed within the housing, wherein one or more controls for the audio amplification unit are coupled to an outer surface of the housing. The one or more speakers can be mounted in a wall of the body member, wherein the one or more speakers are operably coupled to the audio amplification unit.

A generation system (100) of synthesized sound comprises: a first stage (1), wherein features (F) are extracted from an input raw sound and parameters of said features are evaluated; a second stage (2) wherein the evaluated parameters are used to create a plurality of physical models that are metrically evaluated in order to find the parameters of the best physical model, and a third stage (3) wherein the parameters of the best physical model are perturbed in order to create perturbed physical models and a metric evaluated of the perturbed physical models is performed to find the parameters of the best physical model.

The present invention relates to a removable electronic device for emulating at least one sound of a drum-type percussion instrument, said device being intended to instrumentalise a striking element. A defining means defines a striking area on a tangible support. An allocating means allocates a drum element associated with a predetermined sound to the striking area, in a database. At least one sensor generates a stroke signal having at least one piece of stroke information on a stroke of a user with the striking element in the striking area. A computer processing means implements a processing algorithm configured to process the stroke signal to spatially locate said stroke in order to detect the area struck and to determine the drum element corresponding to this area struck. A generating means is configured to generate a sound signal comprising information on the sound virtually generated by said stroke of the striking element in said area struck.
