Digital Saxophone Using Atmega644

Leave a Comment / Phone Projects / Ibrar Ayyub

Abstract My final project was the design of a digital saxophone which can reproduce the sound of an actual saxophone through digitally synthesized electrical waveforms. The digital saxophone consists of a microphone to sense the user blowing into a mouthpiece, push-buttons to control the note to be played, and the Atmel644 Micro-Controller which processes the

Virtual Saxophone Using Atmega644

Leave a Comment / Phone Projects, Sensor - Transducer - Detector Projects / Ibrar Ayyub

Our ECE 4760 final project was to create a virtual saxophone that uses Direct Digitial Synthesis (DDS) to synthesize the output notes. Pushbuttons are connected to a PVC pipe to mimic the saxophone’s mechanical structure, and a microphone that detects noise is used to determine whether or not the user is blowing into the device.
