A foot-operated pedal for programming audio and other effects, including an HMI or Human-Machine Interface that digitally communicates with a CPU, providing the parameters of effects set by the user, where a PC Interface is responsible for the mediation of the communication between the CPU and an external computer used to program the settings and adjustments of the device, with the audio interface having the function of promoting the compatibility between the electrical signal from the musical instrument and the CPU. A graphical user interface to facilitate the creation of an audio effect using icons, a given configuration of icons and interconnections being modeled and employed to generate a given audio effect.

A device is provided as part of a system, the device being for capturing vibrations produced by an object such as a musical instrument. Via a fixation element, the device is fixed to a drum. The device has a sensor spaced apart from a surface of the drum, located relative to the drum, and a magnet adjacent the sensor. The fixation element transmits vibrations from its fixation point on the drum to the magnet. Vibrations from the surface of the drum and from the magnet are transmitted to the sensor. A method may further be provided for interpreting an audio input, such as the output of the sensors within the system, the method comprising identifying an audio event or grouping of audio events within audio data, generating a model of the audio event that includes a representation of a timbre characteristic, and comparing that representation to expected representations.

Methods for using at least one musical instrument mute for electronic modification of sound emitted from a musical instrument. A mute body is positionable within a bell or horn of the musical instrument, and the body has a proximal end portion and is configured to at least partially occlude the bell or horn. A microphone is positioned at the proximal end portion of the mute body and is configured to transduce a sound produced by the musical instrument. A speaker is positioned in the mute body as well. A microcontroller is configured to receive a signal from the microphone and to electronically modify the sound of the instrument when emitted through the speaker. Some mutes also provide a communication transceiver, sensors, and input devices to remotely control and manipulate sound produced by the mute.

A musical sound signal generation device continuously connects any one of a connected zeroth delay unit and a connected second delay unit to a fractional delay block and connects at least any one of a new zeroth delay unit and a new second delay unit to at least any one of the fractional delay block other than the fractional delay block connected to a new first delay unit in response to setting any one of the connected zeroth delay unit and the connected second delay unit as the new first delay unit, setting a delay unit in a preceding stage of the new first delay unit as the new zeroth delay unit, and setting a delay unit in a subsequent stage of the new first delay unit as the new second delay unit in accordance with a change in a designated tone pitch.

An electronic trumpet emulating the valves of a trumpet, playable without a mouthpiece. Electronic sensors detect valve positions and pushbuttons select note intervals and play notes when pressed. An internal microcontroller translates valve and button states into Musical Instrument Digital Instrument (MIDI) messages suitable for transmission to an external music synthesizer or internal MIDI Synthesizer Integrated Circuit.

A virtual instrument can manage separate static and dynamic samples for various notes that can be played by the virtual instrument. In some cases, the static samples correspond to resonance sounds recorded for an instrument and are the same for every note. However, the dynamic samples may correspond to isolated sounds that are recorded for each variation of a note that can be played. In response to a user's selection of a note on a user interface of the virtual instrument, the virtual instrument may determine a rule for layering the various static and dynamic samples for playback.

Embodiments of the present disclosure can provide systems, methods, and computer-readable medium for implementing user interfaces for interacting with a virtual instrument. For example, first touch input indicating a string location of a plurality of string locations within the note selection area. Audio output corresponding to the sting location may be presented on a speaker based at least in part on the first touch input. Second touch input corresponding to an ornamental interface element of the user interface may be received. In response to the first and second touch input, a series of two or more audio outputs may be presented on the speaker according to a predetermined pattern.

A mixing signal processing technique modifies digital audio recordings to simulate the linear and nonlinear effects of propagation and mixing of sounds in air. When multiple sounds or complex sounds comprised of multiple frequencies in the audible spectrum propagate in such a nonlinear medium, they transfer energy into sound at new frequencies given by the sums and differences of the original signal frequencies. The mixing signal processing technique may improve the ability of a system to reproduce the effects of a live performance using a digital audio recording.
