Real-Time Audio Processing with the Sound Disguiser: An Overview

This presentation introduces the Sound Disguiser project, detailing the real-time audio processing capabilities. Attendees will learn how to sample input audio, read from a rotary encoder, and process audio based on selected modes to produce distorted output. We will cover essential components, including the PmodMIC microphone, ADCS7476 analog-to-digital converter, PmodENC rotary encoder, PmodAMP1 amplifier, and the Nexys-2 FPGA. The session aims to familiarize participants with hardware communication, audio processing algorithms, and the journey from concept to implementation.
