New Releases of the Sound Field Synthesis Toolbox for Python and Matlab/Octave

New versions of our Sound Field Synthesis Toolbox are available for Matlab/Octave and Python.

Matlab
This release fixes small bugs, removes obsolete local WFS functions and introduces optional logarithmic spacing of linear secondary sources. For documentation see http://matlab.sfstoolbox.org/en/2.4.2. Download SFS Toolbox 2.4.2 for Matlab.

NEWS (SFS Toolbox for Matlab 2.4.2)

  • extend signal_from_spectrum and spectrum_from_signal to N-dim matrices
  • remove obsolete *_localwfs functions
  • add optional logarithmic spacing for linear secondary sources

Python
This release introduces WFS driving functions in the time domain and an image source model for a point source in the frequency domain. For documentation see http://python.sfstoolbox.org/en/0.4.0.
You can install the toolbox via pip install sfs, see https://pypi.python.org/pypi/sfs/0.4.0.

NEWS (SFS Toolbox for Python 0.4.0)

  • Driving functions in time domain for a plane wave, point source, and focused source
  • Image source model for a point source in a rectangular room
  • DelayedSignal class and as_delayed_signal()
  • Spherical Hankel function as util.spherical_hn2
  • Use spherical_jn, spherical_yn from scipy.special instead of sph_jnyn
  • Generalization of the modal order argument in mono.source.point_modal()
  • Rename util.normal_vector() to util.normalize_vector()
  • Add parameter max_order to NFCHOA driving functions
  • Add beta parameter to Kaiser tapering window
