A vocal music production apparatus for converting vocalized music to produced instrumentals includes a housing front side, a housing back side, a housing left side, a housing right side, a housing top side, and a housing bottom side. A touch screen is coupled to the housing within the housing front side. A microprocessor is coupled within the housing and is in operational communication with the touch screen. The microprocessor includes a digital synthesizer to convert vocal audio inputs to digital music. A microphone, a speaker, a headphone jack, and a battery are coupled to the housing and are in operational communication with the microprocessor. A port is coupled to the housing and is in operational communication with the microprocessor and the battery. A plurality of control buttons is coupled to the housing and is in operational communication with the microprocessor.

A sound generating analog synthesizer that is comprised of potentiometers, a switch or switches and a set of patch jacks has a control system that can be operated in three modes, a manual mode, an automatic mode, and a guided mode; wherein manual mode allows potentiometer and switch positions as well as patch cable connections to be set by hand; wherein automatic mode, automatically sets patch connections as on or off, as well as set potentiometer positions and switch states with electromechanical or electrical devices; and wherein the guided mode provides at least one visual information on how to change the potentiometer positions, switch states and patch jack connections such that a previously obtained sound can be reproduced.

A signal processing system, machine and method of use to dynamically change the parameters of an audio-visual signal processing circuit without making physical contact.

A canonicalizer can be used with or implemented within a natural language understanding (NLU) component of a speech processing system to enable the system to properly identify an entity to which a user refers in a spoken utterance. The canonicalizer may determine a first canonical value using a gazetteer associated with a determined intent of the spoken utterance. The canonicalizer may determine a second canonical value using a look-up table of canonical values. The canonicalizer may then output either the first canonical value or the second canonical value for further NLU processing, such as entity resolution.

Calculation is performed to provide a delay and attenuated oscillation to a blowing pressure detected by a blowing pressure sensor which detects blowing pressure, and a musical sound is generated based on the blowing pressure subjected to the calculation. As a result, for example, a blowing feeling of an electronic wind instrument can be made closer to a blowing feeling of a natural musical instrument.

A method and a device provides a user with the ability to freely improvise or play around with a selection of different chords and be provided with visual guidance assisting the improvisation of melody, while also providing accompaniment consistent with the selection of chords. Sound files consistent with a user selection of a chord and/or a dynamic level are selected from an audio library and played, while the user is given visual cues on a user interface keyboard assisting the user to select notes that are consistent with the chord selected for the accompaniment.

A timing control method includes generating a timing designation signal according to one of a first generation mode for generating the timing designation signal which designates, based on a detection result of a first event in a performance of a music piece, a timing of a second event in the performance, and a second generation mode for generating the timing designation signal without using the detection result, and outputting a command signal for commanding an execution of the second event according to one of a first output mode for outputting the command signal in accordance with the timing designated by the timing designation signal, and a second output mode for outputting the command signal in accordance with a timing determined based on the music piece.

A digital-to-analog converter performs a computation process to start the computation based upon the second clock signal with respect to the digital data of music sound if the computation is not under execution when the control signal is outputted by the signal output process, a control process to inhibit the computation based upon the second clock signal from being started with respect to the digital data of music sound until the computation is not under execution when the computation is under execution, and an output process to convert a computation result of the computation process into an analog signal and output the analog signal.

A sound control device includes an obtainer and a determiner. The obtainer obtains performance information including sound pitch information indicating a sound pitch and sound volume information indicating a sound volume detected as a continuous quantity. The determiner determines a note start and a note end based on a comparison between the sound volume and a sound-volume threshold and based on a change in the sound pitch. Upon determining that there is a predetermined way of change in the sound volume, the determiner determines a time of the change as the note end and determine the time as the note start, irrespective of the comparison between the sound volume and the sound-volume threshold.
