Sound Field Synthesis Toolbox

An open source toolbox for Sound Field Synthesis (SFS) is introduced. The toolbox is able to numerically simulate sound fields synthesized by SFS methods like Wave Field Synthesis or higher order Ambisonics. Various loudspeaker driving signals for the mentioned methods are provided for 2-, 2.5-, and 3-dimensional synthesis. The toolbox allows mono-frequent as well as broadband excitation signals. The latter allows generation of snapshots of the spatio-temporal impulse response of a chosen reproduction technique. The toolbox furthermore includes the computation of binaural room impulse responses (BRIR) for a given SFS setup. These can be used to simulate different sound field synthesis methods via binaural resynthesis. The toolbox is provided for Matlab/Octave and comes with an online documentation.
