An electronic system that can be combined with a wind musical instrument with lateral holes comprising a tubular body defining, on the inside, an air column, comprises at least one device for emitting elastic mechanical waves in the body of the instrument, at least one device for receiving elastic mechanical waves positioned to receive the waves emitted by at least one emission device after their propagation in the material of the body of the instrument and designed to provide at least one reception signal characteristic of the waves received and a device for detecting and locating the disturbance induced by an action of closing at least one lateral hole of the instrument, configured to detect and identify a configuration of closing of the lateral holes of the instrument from the analysis of at least one reception signal, the detection and location device positioned removably inside the air column of the instrument.

An apparatus to detect, analyze, record, and display audio data, including an input unit to allow a user to input musical notes corresponding to the audio data, a processor to analyze the musical notes and to save the musical notes into a file, and a display unit to display notes corresponding to the musical notes on a virtual instrument.

One embodiment of the present application sets forth a method for simulating an audio output of a three-dimensional object that includes a resonant cavity. The method includes receiving an input mesh of a three-dimensional shape and a hole configuration. The input mesh has an outer surface and an internal cavity, and the hole configuration includes one or more holes. The method further includes adding the one or more holes to the three-dimensional shape based on the hole configuration to generate a modified three-dimensional shape having a resonant cavity. The resonant cavity includes the one or more holes and the internal cavity. The method further includes determining an air pressure coefficient matrix for the resonant cavity. The method further includes computing a minimum non-zero eigenvalue for the air pressure coefficient matrix. The method further includes determining an output resonant frequency for the resonant cavity based on the minimum non-zero eigenvalue.

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.
