New

• baumgartner2017: sound externalization model
• baumgartner2016: level-dependent sagittal-plane sound localization model for NH and HI listeners
• hohmann2002: the gfb_ framework of Gammatone filterbank integrated as hohmann2002 framework
• kelvasa2015: sound localization in cochlear-implant listeners
• emuexp: emulation of experiments using interative runs like 3-AFC
• breebaart2001_centralproc: decision stage from Breebaart et al. (2001).
• exp_breebaart2001: reproduces results from Breebaart et al. (2001) based on emuexp
• model initiative: interface to the model initiative (Dietz et al. 2016)

Structural changes:

• baumgartner2014 decomposed into model stages

• exp_spille2013 merged into exp_dietz2011

• directories re-structured:

  • main scripts of a model go to: model. They are called nameyear
  • scripts with model stages (model scripts other than the main one) go to: modelstages. They are called nameyear_postfix
  • scripts not being part of a specific model go to: general. They do not (!) start with model name.
  • scripts generating audio signals go to: signals. They are called sig_nameyear or sig_functionality
  • scripts returning measured data go to: data. They are called data_nameyear
  • scripts with default parameters of other scripts go to: defaults. They are called arg_callingfunction
  • files being compiled to mex files go to: mex. In order to be compiled, they must have the prefix comp_
  • files being compiled to oct files go to: oct
  • other files requiring compilation/installation go to: bin. Their compilation must be considered in make.bat (Windows) and Makefile (Linux/MacOS).
  • HRTFs go to hrtfs. They are in SOFA and will be downloaded on the fly.
  • Lagecy files providing backwards compatibility fo to: legacy
  • binaural, monaural, speech, filters removed

Other updates:

• dietz2011: minor bug fixes
• data_joergensen2011: completion of data
• exp_baumgartner2014: new figures, compatibility improved
• demo_hohmann2002: new figures
• installation simplified (amt_mex does all the installation now)

Version 0.9.7 (10.6.2015)

New:

• Caching of data: see amt_cache and the cache directory.
• Automatic download of auxiliary data. See amt_load and the auxdata directory.
• Control for messages output in the command line. See amt_disp.
• SOFA files for HRTFs: requires SOFA API, see SOFAload.
• Models: zilany2014, joergensen2011, joergensen2013, georganti2013
• Signals: sig_joergensen2011
• Clean documentation (no errors, no warnings).
• makefile for Linux, compiling of cpp files

Structure changes:

• arg_ functions moved to arg directory, comp_ functions moved to mex, directory comp removed
• plot* functions renamed to plot_* and moved to plot directory
• amt_start and amt_mex improved
• readme file for sourceforge added
• reference directory removed (it was a directory with original contributions to the AMT)

• amt_disp introduced for displaying information depending on the start-up condition of the AMT.
• enzner2008 and exp_enzner2008 split in the model and experiment part.
• exp_georganti2013 works for me. Documentation is missing yet.
• may2011 documentation integrated

• Fixed imag ILD in dietz2011
• Added function to load some simulated monaural room impulses responses.
• documentation updates and use of SOFA's remote load functionality in data_baumgartner2014.
• major style overhaul of the Joergsen 2011 and 2013 models. Experiments included etc. Does not yet pass mat2doc, and sound files are missing.
• localizationerror: new performance measures added
