PIC sound player (PCM to PWM converter) using PIC18F1320

Description This project makes a PIC microcontroller play audio PCM sounds using PWM modulation! Pulse-code modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a digital (usually binary) code [1]. Pulse-width modulation (PWM) of a signal or power …

Sound Localization Using Pic

INTRODUCTION We constructed a triangular arrangement of microphones to localize the direction an arbitrary sound is coming from. By recording input from the three microphones, we can cross-correlate the recordings to identify the time delay between the audio recordings. Since the physical placement of the three microphones are known, the direction of the sound can …

Rotary Encoder Outputs

The Sound Designer – A Portable Digital Synthesizer Using Pic

Introduction For this design project, we built a portable digital synthesizer capable of creating a wide variety of sounds designed by the user. The system consisted of a full octave (13 key) keyboard with two-voice polyphony, three rotary encoders for user input, a TFT LCD for visual display, and an SPI DAC for audio output. …
