Development of a real time three dimensional audio system

Abstract

Nowadays, people are more likely to listen to music and song via earphones. They are willing to spend more money buying headphones with enjoying the highest quality sound. People strive to illustrate how a monaural sound synthesizes some particular sounds in 3-D space. And use the Head Related Transfer Function (HRTF) to create and generate a 3-D environment via earphones. The aims of the project is developed a 3-Dimensions audio real-time system with applying Head Related Transfer Function (HRTF) in binaural system. Furthermore, some head related impulse responses (HRIR) measurements of MIT Laboratory are applied in a Matlab® code to generate "spatialized" sounds. For using graphical user interface (GUI) design an audio player, it could provide a user-friendly platform which not only allowed users to select auto-left-right-panning effect, auto-surrounding effect and manually select any directions (Elevation and Azimuth) to listen from a sound source, but also plotted the left and right channels characteristics of both corresponding impulse responses during the music is playing simultaneously.
