Sound Field Synthesis Toolbox 2.2.1 released

Since our last announcement here at, two new releases of the Sound Field Synthesis Toolbox for Matlab/Octave have happend. The highlights of the new versions include a new online documentation at and a new online theory documentation at, which is directly linked in the corresponding code sections. Other big changes include a switch to the MIT license, more fractional delay methods, a new linear interpolation method for HRTFs and an update to the default WFS driving functions.

Download the SFS Toolbox 2.2.1 and have a look at the online documentation how to use it.
