20.500.12556/RUL-134996 Kromatski uglaševalec na STM32F7-Discovery razvojni plošči A Chromatic Tuner on the STM32F7-Discovery Board V diplomskem delu je predstavljen uglaševalec glasbenih instrumentov na razvojni plošči STM32F746G-Discovery, ki v realnem času računa višina tona zvoka iz okolja in uporabniku sporoča odmik od najbližjega poltona. Predstavljene so naprave na razvojni plošči, ki vzorčijo zvok. Našteti so primeri metod, s katerimi se pogosto določa višino tona. Podrobneje sta predstavljeni metodi analize spektra moči in SNAC (Special normalized autocorrelation). Ti metodi sta implementirani na razvojni plošči. Opisan je grafični uporabniški vmesnik na LCD zaslonu. Predstavljene so meritve natančnosti metod. The diploma thesis describes a musical instrument tuner on the STM32F746G-Discovery development board. The tuner determines the pitch of the ambient sound in real time and informs the user of the offset from the closest semitone. The hardware which samples sound on the development board is described. The common pitch detection methods are listed. The power spectrum analysis and SNAC methods are explained in more detail. They are implemented on the development board. The graphic user interface on the LCD screen is described. The accuracy of both pitch detection methods is measured.
