A sound capture device is affixed to an acoustic instrument to capture the natural sound output of the instrument. The captured sound signal is routed to an electronic sound augmentation system that is configured to augment the captured sound with spatial sound effects such as reverb, echo, delay, etc. The processed and augmented sound is then reproduced via a vibrating driver that has been affixed to the body of the acoustic instrument. This creates a situation where the body of the musical instrument, responding to a series of vibrations produced by the vibrating driver, acts as a speaker component, reproducing a rich augmented sound output that comprises the sum of the sound produced by the original sound production capabilities of the acoustical instrument plus the added augmented or enhanced sound effects.

Embodiments of the present disclosure provide a harmony processing method and apparatus, a device, and a medium, and the method includes: acquiring a harmonic interval corresponding to a target harmony control in response to a triggering operation on the target harmony control; performing, according to the harmonic interval, sound modification processing on a first sound input originally to obtain a second sound, in which an interval between the first sound and the second sound is the harmonic interval; and generating a target audio according to the first sound and the second sound, wherein the first sound and the second sound are presented as different harmonic parts in the target audio.

A musical instrument mute, a mute body, a microphone, a speaker, and a microcontroller 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 control and manipulate sound produced by the mute.

A system for modifying an audio signal comprises a computer including a first digital signal processor (DSP). The first DSP includes a first module and a second module. The first module is coupled to the interface to provide a musical instrument with a set of testing input signals and obtain a set of testing output signals from the musical instrument via the interface. The second module is configured to perform functions including: analyzing the set of testing output signals to obtain a set of parameters, constructing an acoustic transducer to model characteristics of the musical instrument based on the set of parameters, and receiving the audio signal to modify the audio signal using the acoustic transducer, wherein the first DSP module obtains the set of parameters at least by identifying occurrences when an output level state determined at least based on the set of testing output signals significantly changes.

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.

A method includes measuring an environmental parameter that indicates a sensory condition at a location of an electronic device within a physical environment. The method includes determining whether the environmental parameter is within an acceptable range. The method includes, in response to determining that the environmental parameter is not within the acceptable range, triggering presentation of augmented content in order to enhance the sensory condition at the location of the electronic device.

A method includes displaying, on a display, virtual acoustic instruments as being overlaid onto a pass-through of a physical environment. The method includes performing, based on respective characteristics of the virtual acoustic instruments, an acoustic simulation in order to generate estimated acoustic parameters for respective locations within the physical environment. The method includes displaying, on the display, an indication of the estimated acoustic parameters.

An information processing method implemented by a computer, the information processing method including, generating pedal data representing an operation period of a pedal that extends sound production by key depression, from playing data representing a playing content.

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.
