The idea behind this project was to create an instrumental tuner for a trumpet that not only determined the pitch, but also adjusted it for you. This concept was inspired by the difficulty of beginning trumpet players to learn tuning and recognize what pitch to listen to. Through automated adjustment, the system is insensitive to naturally out of tune notes and temperature variation. Using sound acquisition, signal processing, and mechanical control, a prototype was realized that found a pitch center within 3 seconds for a range of notes with an accuracy of 1Hz.
Automation World would like to thank National Instruments for connecting us with the UCSD Pitcher Perfect Tuner team to make this "Engineering School Innovations" installment possible.
