  • Precise electronic aid to musical instrument tuning
    Patent number: 5016515
    Abstract: An aid to tuning musical instruments. A microprocessor-controlled frequency standard is used to control a shift-register whose data is the digitized sound detected by a microphone. The data from the shift register are loaded into a parallel-load latch and then used to control an array of indicator lights. The pattern in the lights indicates the error in pitch of the sounded note. A person tunes a musical instrument by making the pattern in the lights become nearly stationary. The same synthesized frequency is made available in a speaker.
