An acoustic device includes an audio recording playback unit, an analysis unit, and an acoustic effect imparting unit. The audio recording playback unit records and plays back string independent acoustic signals for each string independent acoustic signal. The string independent acoustic signals respectively correspond to different strings of a stringed instrument and being independent from each other. The analysis unit analyzes at least one string independent acoustic signal from among the recorded string independent acoustic signals. The acoustic effect imparting unit imparts an acoustic effect to the at least one string independent acoustic signal for each string independent acoustic signal, based on a result of the analysis by the analysis unit.

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.

A controller, method, system, and computer-readable medium, for producing control signals. The controller comprises a pressure sensor, a hinged input mechanism configured to receive input forces and direct them towards the sensor, and a processor. The processor is configured to receive a signal from the pressure sensor indicating that the hinged input mechanism is being depressed or released and, based on the received signal, to determine, during a time interval, a rate of change of pressure detected at the sensor. The processor also generates a control signal associated with the hinged input mechanism, wherein the control signal comprises a velocity characteristic representing a speed at which the hinged input mechanism is depressed or released, and the velocity characteristic is based at least partly on the determined rate of change of pressure. In one example embodiment, the control signal is an audio control.

A method for producing and streaming music generated from biofeedback. The method employs machine-readable language instructions that alter received signals from a wearable biofeedback device, generating musical tones to be played on a portable electronic device and/or shared with others. The varying musical tones that are produced by the method can be modulated by the user to reach a targeted state of emotion.

The implementation of modal processors, which involve the parallel combination resonant filters, may be costly for applications such as artificial reverberation that can require thousands of modes. In one embodiment, the input signal is decomposed into a plurality of subbands, the outputs of which are downsampled. In each downsampled band, resonant filters are applied at the downsampled sampling rate, and their output is upsampled and filtered to form the band output.

Systems and methods are directed to generating music. In one example, an electronic musical instrument includes a first handheld unit. The electronic musical instrument further includes a second handheld unit, the second handheld unit being communicatively coupled to the first handheld unit. The first handheld unit includes a plurality of input controls configured to indicate a selection of a note of a musical scale. The second handheld unit is configured to initiate output of the selected note.

To generate a melody, one or more machine-readable constraints are accepted from a user through a user interface. The constraints include rhythm constraints and pitch constraints. A sequence of musical elements is generated based on the constraints, each of the musical elements specifying, in machine-readable data, a musical pitch or silence and a duration of the musical pitch or silence. The pitch constraints prescribe pitches in the sequence of musical elements and the rhythm constraints prescribe rhythm of the sequence of musical elements. The sequence of musical elements is rendered in human-perceivable form as a melody.

A musical instrument provides the ability to both automatically detect an initial note or chord played on a touchscreen, correct the initial note or chord to neutral tone or tones, as well as to slide the note or chord to a new location, providing a continuously variable and continuous pitch to the new location, thereby creating a new type of keyboard instrument. The keyboard is operative to initialize a series of pitch arrays, one for each key, where the pitch array value is computed to provide a lookup or translation from a pressed key into an output pitch with fine granularity which matches the granularity of resolution of the touchscreen.

A sound generation method includes receiving a control value at each of a plurality of time points on a time axis, accepting a mandatory instruction, generating an acoustic feature value of a specific time point, by using a trained model to process the control value and an acoustic feature value sequence, and updating the acoustic feature value sequence. The acoustic feature value sequence is updated by using the generated acoustic feature value, as the mandatory instruction has not been received for the specific time point. As the mandatory instruction has been received for the specific time point, one or more alternative acoustic feature values of one or more time points, which includes at least the specific time point, in accordance with the control value for the specific time point is generated, and the acoustic feature value sequence is updated by using the one or more alternative acoustic feature values.

A method for performance data transmission control executed by one or more processors includes receiving performance data associated with output timings, the performance data including continuously varying operation data whose value changes continuously; detecting characteristic points of change from the continuously varying operation data; thinning out the continuously varying operation data other than the characteristic points of the change; and generating unit performance data to be transmitted to an external device, based on the performance data in which the characteristic points in the continuously varying operation data have been detected and in which the continuously varying operation data other than the characteristic points have been thinned out.
