Microcontroller-based System for Real-time Audio Signal Processing

Rad opisuje sustav za digitalnu obradu audio signala zasnovan na mikrokontroleru STM32F407, audio kodeku TLV320AIC3104 i Android aplikaciji. Audio kodek uzorkuje analogni signal te šalje njegovu digitalnu reprezentaciju na mikrokontroler. Mikrokontroler obavlja digitalnu obradu zvuka u ovisnosti o parametrima koje zadaje korisnik. Korisničko sučelje je Android aplikacija koja se sastoji od klizača i tipki. Aplikacija šalje parametar Bluetooth vezom na Bluetooth modul HC-05 koji je serijski povezan s mikrokontrolerom. Rad opisuje implementacije zvučnih efekata, programsku potporu sustava te njegove komponente.The thesis describes a digital audio processing system based on the STM32F407 microcontroller, the TLV320AIC3104 audio codec and the Android application. The audio codec samples an analog signal and sends its digital representation to the microcontroller. The microcontroller performs digital sound processing depending on the parameters provided by the user. The user interface is an Android application that consists of slides and keys. The application sends a Bluetooth parameter to the Bluetooth module HC-05 which is serial-connected to the microcontroller. The thesis describes the implementation of sound effects, system support and its components
