Real-time stereophonic sound using a ring of loudspeaker
The goal of this research is to create a real-time spatialization system based on inverse filtering and loudspeaker grouping. Currently, stereophonic sound is used in a variety of products such as video games, movies, and music technology by means of headphones. However, headphones have some disadvantages, such as not being able to share the sound with others, and being worn, it is easy for listeners to get tired. Therefore, this research seeks an implementation of stereophonic sound using loudspeakers. Past research has led to the development of various systems for stereophonic sound by loudspeakers. However, each of these systems has its own advantages and disadvantages. A new and original sound system was also developed in our lab. This sound system is done with a small number of loudspeakers, and the sound image does not collapse as the listener moves around. However, it is computationally intensive and can currently only be run offline with MATLAB. To do this in real-time, this research use an application called Pure-data.
