Signal Processing Systems Laboratory
Signal processing that enriches people’s life
Signal processing involves inputting voice and music data and processing them into beneficial data. Our laboratory is conducting research with the aim of realizing signal processing systems that can reproduce good sounds. Research topics range from pure research for presentation at academic society conferences to the development of specific systems, but all topics involve the full use of computer.
