Telecommunications Software and Multimedia Laboratory

Spatial Audio and Room Acoustics (SARA)

Project description

SARA project is funded by Academy of Finland (project no. 201050) and the funding period is Jan. 1, 2003 - Dec. 30, 2006. The SARA project is an academic research project. The research problems can be divided into three areas: room acoustics, digital signal processing, and psychoacoustics.

Research areas in SARA


The 3rd March 2005 we'll have a SARA day, see the program
