audio-dsp

Audio processing with Digilent I2S2 and STM32 development board

audioeffectsproject

Audio Effects Circuit Design & Embedded Systems (STM32F407 microcontroller) Design Project. Goal: with an analog audio input, pitch shift or add echo effect and output to a speaker. Circuit: designed AC level shifting circuit, active bandpass filter, LED matrix display and DAC quantization error smoothing in KiCad; manufactured as a printed circuit

audioplayer

Stm32 project which is used to receive audio data via I2S and play it using DAC.
