A sound generation method that is realized by a computer includes receiving a first feature amount sequence in which a musical feature amount changes over time, and using a trained model that has learned an input-output relationship between an input feature amount sequence in which the musical feature amount changes over time at a first fineness and a reference sound data sequence corresponding to an output feature amount sequence in which the musical feature amount changes over time at a second fineness that is higher than the first fineness, to process the first feature amount sequence, thereby generating a sound data sequence corresponding to a second feature amount sequence in which the musical feature amount changes at the second fineness.

A new and improved Digital Musical Instrument includes a hardware segment that electronically detects the physical inputs of a musicians musical playing style or articulated intent; a Software segment that interprets and formulates the data output from the hardware segment, to be applied to any digitally modulated synthesizer or recording sampler; and an optional expanded method of sampling or digitally recording articulated sounds of acoustic instruments.

An audio processing method obtains observed envelopes of picked-up sound signals including a first observed envelope representing a contour of a first sound signal including a first target sound from a first sound source and a second spill sound from a second sound source and a second observed envelope representing a contour of a second sound signal including a second target sound from the second sound source and a first spill sound from the first sound source; and generates, based on the observed envelopes, output envelopes including a first output envelope representing a contour of the first target sound in the first observed envelope and a second output envelope representing a contour of the second target sound in the second observed envelope, using a mix matrix including a mix proportion of the second spill sound in the first sound signal and a mix proportion of the first spill sound in the second sound signal.

A device is provided for capturing vibrations produced by an object such as a musical instrument such as a cymbal of a drum kit. The device comprises a detectable element, such as a ferromagnetic element, such as a metal shim and a sensor spaced apart from and located relative to the musical instrument. The detectable element is located between the sensor and the musical instrument. When the musical instrument vibrates, the sensor remains stationary and the detectable element is vibrated relative to the sensor by the musical instrument.

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.

Methods and apparatus to extract a pitch-independent timbre attribute from a media signal are disclosed. An example apparatus includes an audio characteristic extractor to determine a logarithmic spectrum of an audio signal; transform the logarithmic spectrum of the audio signal into a frequency domain to generate a transform output; determine a magnitude of the transform output; and determine a timbre attribute of the audio signal based on an inverse transform of the magnitude.

A method and an information processing apparatus to generate a digital score file of a song are described. The information processing apparatus includes processing circuitry. The processing circuitry is configured to obtain a candidate audio file satisfying a first condition from audio files of unaccompanied singing of the song without instrumental accompaniment. The processing circuitry is configured to divide the candidate audio file into valid audio segments based on timing information of the song, and extract pieces of music note information from the valid audio segments. Each of the pieces of music note information includes at least one data set of a music note in the song. The data set includes an onset time, a duration, and a music note value of the music note. The processing circuitry is configured to generate the digital score file based on the pieces of music note information.

Methods and apparatus to classify media based on a pitch-independent timbre attribute from a media signal are disclosed. An example apparatus includes means for accessing a media signal; and means for: determining a spectrum of audio corresponding to the media signal; and determining a timbre-independent pitch attribute of audio of the media signal based on an inverse transform of a complex argument of a transform of the spectrum.

A foot stomp percussion device that creates dual tones when stomped on by the musician. The foot stomp comprises a housing comprising a main portion and a bottom ledge portion that extends beyond the main portion to enhance stability. In one embodiment, the main portion of the housing comprises a smaller and shallower cavity containing a piezo transducer and a larger and deeper cavity coupled to a volume potentiometer, as well as one or more electrical outputs to connect the foot stomp to a sound amplification system. The solid back portion of the foot stomp creates a low frequency tone when stomped on, and the front portion containing the larger and deeper cavity creates a high frequency tone when stomped on.
