Realtime audio processing on Artix-7 FPGA using VHDL, currently supports echo, reverb, and delay effects.
Table of Contents
This project was created to demonstrate the capabilities of the Artix-7 FPGA at course Digital Design at University of Ljubljana FRI. The project uses the Digilent Nexys 4 DDR board, which has a Xilinx Artix-7 FPGA. The project uses the onboard audio codec to process audio in real time. The project currently supports echo, reverb, and delay effects. The project is written in VHDL and uses the Xilinx Vivado IDE.
List of things you need to use the software and how to install them.
- Vivado

- Nexys 4 DDR
Load the program to the FPGA and connect the audio output to a speaker. The audio input can be connected to a microphone or a audio device, such as a phone or a computer. The audio input is processed in real time and the output is played through the speaker. The effects can be changed by pressing the buttons on the board.
