Abstract:
Embodiment apparatus and associated methods relate to adapting an actuator to adjust the tension of a musical instrument string, configuring a sensor to detect vibration propagated through the musical instrument body, configuring a noise removal filter to remove an undesired signal from vibration propagated through the musical instrument body, and automatically tuning the musical instrument based on adjusting the musical instrument string tension by the actuator while removing the undesired signal, until the fundamental frequency propagated through the instrument body by the vibration of the musical instrument string is within a predetermined tolerance of a reference frequency. In an illustrative example, the undesired signal may be actuator vibration. In some embodiments, actuator vibration spectral content may vary as a function of actuator torque, and, the noise removal filter may be adapted in real time. Various examples may advantageously provide faster and more accurate stringed musical instrument tuning.

Claim (Index 1):
An apparatus, comprising:\n a stringed musical instrument tuning device configured to adjust tension of a musical instrument string with a dynamic string tension adapting action rotationally applied to a tuning peg, the stringed musical instrument tuning device comprising:\n an actuator, adapted to releasably couple with a musical instrument tuning peg and radially displace the tuning peg about the tuning peg longitudinal axis of rotation; \n a sensor system, adapted to receive and transduce to electronic form a signal package comprising: a sound signal emitted by the musical instrument string; and, an undesired noise signal; and, \n a controller, comprising:\n a processor, operably coupled with the actuator, and communicatively coupled with the sensor system; and, \n a memory that is not a transitory propagating signal, the memory connected to the processor and encoding computer readable instructions, including processor executable program instructions, the computer readable instructions accessible to the processor, wherein the processor executable program instructions, when executed by the processor, cause the processor to perform operations comprising:\n receive the signal package from the sensor system; \n configure a noise removal filter to remove the undesired noise signal from the signal package; \n recover an approximation of the sound signal based on applying the noise removal filter to substantially remove the undesired noise signal from the signal package; \n activate the actuator to apply corrective tuning peg radial displacement calculated as a function of the recovered sound signal approximation frequency measured by the processor, to tune the string to a predetermined reference frequency; and, \n automatically tune the musical instrument based on removing the undesired noise signal while activating the actuator to adjust the musical instrument string tension, until the fundamental frequency of the musical instrument string is within a predetermined tolerance of the reference frequency.
