A derivation unit (240) determines, as a specified rhythm component of a musical piece, a rhythm component detected within a predetermined time range including a time of reception of tap timing information TAP and derives a first frequency band the spectrum intensity of which is equal to or greater than a predetermined value. The derivation unit (240) also determines, as an unspecified rhythm component, a rhythm component detected outside the predetermined time range including the time of reception of the tap timing information TAP and derives a second frequency band the spectrum intensity of which is equal to or greater than the predetermined value. Thereafter, a calculation unit (250) calculates a third frequency band, which is included in the first frequency band and which does not include the second frequency band, and then transmits, to a filter unit (260), a passed-frequency designation BPC that designates the third frequency band. The filter unit (260) then subjects a musical piece signal MUD to a filtering process using the designated frequencies as a signal pass band. Subsequently, a vibration signal generation unit (270) generates a vibration signal VIS on the basis of a signal FTD having passed through the filter unit (260).

A method and system are provided for extracting features from digital audio signals which exhibit variations in pitch, timbre, decay, reverberation, and other psychoacoustic attributes and learning, from the extracted features, an artificial neural network model for generating contextual latent-space representations of digital audio signals. A method and system are also provided for learning an artificial neural network model for generating consistent latent-space representations of digital audio signals in which the generated latent-space representations are comparable for the purposes of determining psychoacoustic similarity between digital audio signals. A method and system are also provided for extracting features from digital audio signals and learning, from the extracted features, an artificial neural network model for generating latent-space representations of digital audio signals which take care of selecting salient attributes of the signals that represent psychoacoustic differences between the signals.

Indicating what should be played in a piece of music with a music document, including: displaying a part of the music document when a user plays the piece; receiving a real-time audio signal of the playing; automatically determining a playing position within the piece of music based on the real-time audio signal; automatically scrolling the music document on a display depending on the playing position; estimating at least the following from the real-time audio signal: activity; tonality; and tempo used in automatically determining the playing position determined from playing speed of the user. The estimating of the activity includes detecting whether the user is producing any sounding notes. The estimating of the tonality is based on an array of chord models that represent different chords that appear in the music document and allow calculating the probability that the corresponding chord is being played in various real-time audio signal segments.

A computer-implemented reproduction control method includes reproducing sound from sound data representing a series of sounds including first sound and second sound that follows the first sound. The method includes starting reproducing the first sound, continuing the reproduction of a first sound until an end of the first sound in response to receiving a first instruction in a reproduction period of the first sound, stopping the reproduction of the first sound, and after the stopping of the reproduction of the first sound, starting reproducing the second sound in response to receiving a second instruction provided by a user.

A content control device includes: a plurality of controls to which a plurality of parameters for controlling properties of a content containing at least one of sound and video are respectively assigned, each of the plurality of controls outputting a first indicated value in accordance with an operation amount of the control; and a processor configured to previously create setting information used to determine respective values of the plurality of parameters in accordance with the second indicated value; determine the values of the plurality of parameters corresponding to the second indicated value respectively in accordance with the second indicated value and the setting information; and revise each of the values of the parameters to be determined in accordance with the first indicated value outputted for the control assigned to the parameter.

Systems and methods for selecting an audio track by performing a gesture on a track-list image are provided. The system includes a processor that performs a method including displaying the audio-track list, detecting a contact with the touchscreen display at a location corresponding to the audio track, detecting a continuous movement of the contact in a direction, detecting a length of the continuous movement, and selecting the audio track if the continuous movement has a length longer than a threshold length. The method includes shifting text associated with the audio track based on the length and direction of the continuous movement. The method includes determining that the selection is a command to queue the audio track for playback or add it to a preparation track list. This determination may be based on the direction of the continuous movement.
