ABSTRACT:
There is provided a method of determining the pitch in string instruments that are excited by plucking or striking, wherein a vibration of a string is converted by a transducer into an electrical signal and the electrical signal is evaluated.
Up to now, the transducers have primarily been electromagnetic transducers for which a plurality of evaluation algorithms and methods are available. Now however, one also wants to be able to use pressure transducers without having to use new evaluation algorithms and methods.
To this end, a pressure transducer is used as the transducer and the electrical signal is subjected to differentiation with respect to time.
