A device is provided for capturing vibrations produced by an object such as a musical instrument such as a drum head of a drum kit. The device comprises a detectable element, such as a ferromagnetic element, such as a metal shim and a sensor spaced apart from and located relative to the musical instrument. The detectable element is located between the sensor and the musical instrument. When the musical instrument vibrates, the sensor remains stationary and the detectable element is vibrated relative to the sensor by the musical instrument.

A harmonic-based intensity regulation system, method and device, disclosed herein, is applicable to sound assets. The system, in an embodiment, includes one or more data storage devices or tangible mediums that store or include a plurality of computer readable instructions configured to direct one or more processors to receive one or more inputs. The one or more inputs correspond to: a selection of one of a plurality of different harmonic classes, wherein each of the harmonic classes is associated with a variable harmonic frequency; a frequency range that is dimensioned or otherwise great enough to bound the variable harmonic frequency of the selected harmonic class and a plurality of other frequencies; an intensity threshold; and an amount of an intensity change. The instructions are also configured to direct the one or more processors to detect whether one or more frequencies of a frequency spectrum satisfy a regulation condition. The regulation condition includes a first requirement for the one or more frequencies to be within the frequency range, and the regulation condition also includes a second requirement for the one or more frequencies to have a designated relationship with the intensity threshold. The instructions are configured to direct the one or more processors to change an intensity of the detected one or more frequencies by at least part of the amount. The change can include an intensity decrease, an intensity elimination or an intensity increase.

An adjustment of an audio signal based on an orientation variation amount is carried out according to a surrounding audio condition. An audio signal processing device includes an audio signal analysis unit, an orientation variation analysis unit, and an audio signal adjustment unit. The audio signal analysis unit acquires an audio signal and sets a target value for an audio adjustment on the basis of the audio signal. The orientation variation analysis unit acquires orientation information and generates an orientation variation amount on the basis of the orientation information. The audio signal adjustment unit adjusts the audio signal toward the target value according to the orientation variation amount.

A manipulator includes a light source that emits light; a rotatable member that is rotatable around an axis; and an operation member having a substantially disk shape, attached to the rotatable member so as to be rotatable together with the rotatable member, the operation member including a light guide member that guides light incident from the light source, and a wheel member arranged on one plate surface side of the light guide member, wherein the rotatable member has a holding portion that holds the light guide member.
