Data sonification is an important tool to enhance a user's ability to capture and process complex information. In this system, stock market data for the top 128 publicly traded stock options are analyzed for the sonification. This information includes the daily trading price and volume of each stock. Audio streams for conveying the daily information of each stock are generated using sine tone click trains, pitch alterations, and noise bursts. Each audio stream is mapped to an individual loudspeaker in the 128 loudspeaker array of Rensselaer’s Collaborative-Research Augmented Immersive Virtual Environment Laboratory (CRAIVE-Lab) to create a high-density spatialized sonification within the immersive virtual environment.
