ltfat - 2.1.1

From the ChangeLog

  • New function for computing higher order phase derivatives: gabphasederiv
  • New function doing the adjustable reassignment: gabreassignadjust
  • New function for the Gabor transform phase reconstruction: constructphase, constructphasereal
  • New filterbank-generating function: audfilters
  • New generic quadratic TF distribution function: quadtfdist
  • New functions for reading and writing wav files (since wavread and wavwrite were removed in Matlab 2015b): wavload, wavsave (taken from VOICEBOX http://www.ee.ic.ac.uk/hp/staff/dmb/voicebox/voicebox.html)
  • Added 'nojava' flag to ltfatstart to optionally disable adding the blockproc JAVA classes to the classpath.
  • Updated the lBFGS method in frsynabs according to the new paper.

ltfat - 2.1.0

From the ChangeLog

  • New filterbank-generating function: warpedfilters
  • New filterbank spectrogram reassignment function: filterbankreassign
  • ltfatarghelper is now also implemented as a MEX file.
  • The block function can now handle synchronized simultaneous playback and recording. E.g. {'rec','file.wav'} plays a wav file while recording. This is different from the option 'playrec', which works the "other way" i.e. it records and play the recorded.
  • Function framebounds(...,'iter') now uses pcg to represent the inverse of the frame operator when calculating the lowest eigenvalue using eigs.
  • Added implementation of some quadratic time-frequency representations: Rihaczek, Wigner-Ville
  • Fixed #112 (Sourceforge): Octave package now compiles on Windows (mxe version) thanks to John Donoghue.
  • Related to #111 (Sourceforge): Wavelet filters were hand-centered around the origin.
  • compfilterbank, compifilterbank and ltfatarghelper can be compiled as MEX files on Octave.
