Digital Sound module 1

Introduction

This project is a module #1 for Digital Sound Lecture: Binaural Effect

Learning Objective

Implement sound-manipulating effect through stereo speaker

Content

Topic

Implement 3D Aural Effect by moving the sound source back and forth

Principle & Theory

Used difference between intensity of the sound and left and right balance, based on psychoacoustic

Problem

Generate sound as an object that hover around the listener's head

  1. Prepare 1 second-length .wav audio sample (16000Hz, 16-bit, stereo)
  2. Program has to read the prepared 4 second-length audio sample as an input
  3. Save the audio sample as the following effect above

Solution

  • Input: 1 second mono frequency sound (16000Hz, 16-bit, stereo), file source & exe must be in the same directory
  • Output: 4 second-length result audio sample with 3D aural effect hovering above in circular motion

FMOD Description
To summarize, I simply utilized angular velocity considering the length of the sound

Library

Used FMOD Library to manipulate sound source as an object
