Introduction This microcontroller project is a compact digital melody player built around the ATmega8 and simulated in Proteus. It generates musical tones through a speaker by using the AVR’s sound output timing and a sequence of predefined note values. In simple terms, the circuit acts like a tiny embedded music box that plays recognizable melodies […]

Project Introduction Our project is a spatial audio map of Collegetown that allows the user to use a joystick to virtually travel around the Collegetown crossing area and hear surrounding, directional sound. Our project takes inspiration from Street View, an interactive technology featured in Google Maps that provides users the ability to visually explore the
Introduction Sound Byte The Snorecorder detects snoring sounds from a sleeping person and records the time and intensity of each snore. The data is written to an SD card, which can be easily viewed on a personal computer. Synopsis The Snorecorder determines and records snore events and functions in two modes, “trigger” and “continuous”; Trigger

Introduction For our ECE 4760 final project, we designed and built an array of 12 independently-controllable speakers to implement an acoustic phased-array system. The system samples a standard audio input signal at approximately 44.1 kHz, and then outputs this signal to each of 12 speakers, each with a variable delay. The idea behind a phased-array

Introduction “A device that pitch-shifts voice in real time” For our final project, we attempted to implemented a real-time vocal pitch shifter. The system was designed to work as follows: a user speaks into a microphone, their vocals are processed using a pitch shifting algorithm, and the resulting signal is output through speakers. All of

A DIY ATTiny44 based guitar preamp+effector. All the audio processing is done digitally on-board. So it is definitely not a HiFi system, but something you can definitely have fun programming. You can program the audio properties in Arduino IDE and create mobile apps that talk to the module for remotely controlling the effects. This instructable
