Since our last announcement here at spatialaudio.net, 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 http://matlab.sfstoolbox.org and a new online theory documentation at http://sfstoolbox.org, 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.
NEWS (2.2.1)
- fix delayoffset for FIR fractional delay filter
- add findconvexcone()
- simplify convolution()
- add linear interpolation working in the frequency domain
- fix pm option for delayline()
NEWS (2.2.0)
- fix impulse response interpolation for three points
- add the ability to apply modal weighting window to NFC-HOA in time domain
- change license to MIT
- update delayline() config settings
- add Lagrange and Thiran filters to delayline()
- replace wavread and warwrite by audioread and savewav
- convolution() excepts now two matrices as input
- allow headphone compensation filter to be a one- or two-channel wav file
- add new online doc at http://matlab.sfstoolbox.org/
- fix greens_function_mono() for plane wave and 3D
- replace conf.ir.useoriglength by conf.ir.hrirpredelay
