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 41):
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 sound signal comprising vibration propagated through the musical instrument body to the sensor system: \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:\n string model data configured to represent string physical properties comprising a relationship between tuning peg radial displacement and frequency; and, \n 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 sound signal from the sensor system; \n configure a noise removal filter to remove actuator vibration from the vibration propagated through the musical instrument body to the sensor system; \n recover a tuning sound signal based on applying the noise removal filter to substantially remove the actuator vibration from the vibration propagated through the musical instrument body to the sensor system; \n activate the actuator to apply corrective tuning peg radial displacement calculated as a function of the recovered tuning sound signal frequency measured by the processor and the actuator angle of rotation calculated as a function of the string model, to tune the string to a predetermined reference frequency; and, \n automatically tune the musical instrument based on removing the actuator vibration 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.
