I had this one project where the device was supposed to speak out the output. And I was too Lazy to actually go and build a PC based application and not that lazy to make it on a micro controller. So here is some of my research where i am gonna show you how to […]

Introduction “This device allows friends to learn songs, create their own songs, and collaboratively merge them.” Our final project for ECE 4760 is a fully customizable button keyboard that has a variety of features to allow for collaborative music-making between friends. Each keyboard has eight fully programmable buttons; any button can play any valid MIDI

Data transmission over sound is used in many communication protocols, the most common being Dual-Tone Multi-Frequency signaling (DTMF). It is used to dial phone numbers and the frequency combinations chosen for the digits are very familiar to the general public. It was also used in early modems to request internet connections and its characteristic sound

For our ECE 4760 final project, we designed and built a drum trainer that can be attached to most Japanese drum surface and will detect and wirelessly transmit different drum hit types to other players’ drum trainers. The trainer is able to determine whether the user makes a “Loud Beat”, a “Soft Beat”, or a

Introduction We created a device that determines the RGB content of a surface and then speaks the color or plays a musical tone at the sound frequency mapped to the color. The device can convert the color to sound directly or function as a cassette player that plays through a tape of colors. The user

Our final project is to build a multifunctional music box. This music box can generate different songs in different instrument sounds, i.e. piano, organ, by FM synthesis. The theme and harmony are in two different channels. Besides, the music box can also be electrical piano by which users can play their own music, the piano

Introduction For our ECE 4760 Final Project, we use an infrared LED and phototransistor armband to detect muscle inflections in arm and wrist movement which are used to manipulate the volume and speed of pre recorded songs. By pumping your fist, you will change the speed at which the song is playing. Isolated wrist movements

Our ECE 4760 final project was an audio spectrum analyzer that would display a histogram-style visualization of an audio signal. We were able to successfully display the frequency spectrum content of an audio signal in real-time using a black and white histogram visualization with bins arranged from left to right corresponding to low to high

We implemented an optical microphone which converts distant vibrations, including sound, to an audio signal. Measuring the reflection of a laser beam from windows or glass, it possible to hear sounds near the target. The system also includes frequency spectrum analysis with a real-time display and user-configurable ranges, and it also has an output for

n our final project, we designed an electronic multifunction instrument with a LCD touch screen and a microphone. The user can play three kinds of instruments on it — xylophone, flute and piano. Each instrument has a different interface and timbre. The piano part has a record/replay function which can echo the song previously played
