# Sound Field Synthesis Toolbox 2.1.0 released

A new release of the Sound Field Synthesis Toolbox for Matlab/Octave is available. The highlights of the new version include several improvements for time-domain NFC-HOA simulations, new virtual line sources for WFS and NFC-HOA, and the ability to set t=0 for time-domain simulations to the start of the virtual source.

Download the SFS Toolbox 2.1.0, PDF documentation and have a look at the tutorial on github how to use it.

NEWS:

- make conf struct mandatory - add new start message - fix handling of 0 in least squares fractional delays - fix NFC-HOA order for even loudspeaker numbers to N/2-1 - add conf.wfs.hpreFIRorder as new config option (was hard coded to 128 before) - speed up secondary source selection for WFS - rename chromajs colormap to yellowred - fix tapering_window() for non-continuous secondary sources - remove cubehelix colormap as it is part of Octave - add conf.wfs.t0 option with is useful, if you have more than one virtual source - virtual line sources are now available for monochromatic WFS and NFC-HOA - allow arbritrary orders for time-domain NFC-HOA simulations
