===Data Formats=== | ===Data Formats=== | ||
A collection of various signal data formats can be found [http://www.dpmi.tu-graz.ac.at/~schloegl/matlab/eeg/ here]. Many formats are supported by the [http://biosig.sf.net/ BIOSIG]-toolbox for Octave and Matlab. | A collection of various signal data formats can be found [http://www.dpmi.tu-graz.ac.at/~schloegl/matlab/eeg/ here].

===Speech and Signal Processing Links=== | |||
The following packages contain routines that can be made to work with Octave. Sometimes a little effort is required. | |||
*OctaveForge contains a sizable collection of signal and image processing routines | |||
*Alois Schloegl's Time series analysis toolbox is also available at OctaveForge | |||
*Mike Brookes' Voice Box (http://www.ee.ic.ac.uk/hp/staff/dmb/voicebox/voicebox.html) | |||
*University of Sheffield's Matlab Auditory and Speech Demos (http://www.dcs.shef.ac.uk/~martin/MAD/docs/mad.htm) | |||
*Malcolm Slaney's Auditory Toolbox (http://rvl4.ecn.purdue.edu/~malcolm/interval/1998-010/) | |||
*Philip Loizou's COLEA speech analysis toolbox (http://www.utdallas.edu/~loizou/speech/colea.htm) | |||
*Levant Arslans's Speech Processing Toolbox (http://cslr.colorado.edu/software/rspl.html) | |||
*John Hansen's Additive noise sources (http://cslr.colorado.edu/software/rspl.html) | |||
*Dennis Brown's SPCtools (ftp://svr-ftp.eng.cam.ac.uk/pub/comp.speech/tools/spctools) has code for AR and ARMA modelling, particularly in the spcline subdirectory (Note that the version at mathworks is slightly older). | |||
*Steve Niu's AUDI (ftp://ftp.mathworks.com/pub/contrib/v4/systemid/audidemo.tar) and Arthur Jutan's recursivels (ftp://ftp.mathworks.com/pub/contrib/v4/control/recursivels.tar) for ARMA modelling. AUDI worked well enough for me with a bit of fiddling. Haven't tried recursivels. | |||
*Peter Assmann's Track Draw (http://www.utdallas.edu/~assmann/TRACKDRAW/trackdraw.html) has code for a klatt synthesizer | |||
*Time-Frequency Tool box (http://www-isis.enst.fr/Applications/tftb/iutsn.univ-nantes.fr/auger/tftb.html) from CNRS & Rice has code for AM/FM modulation amongst other cool stuff | |||
*Christophe Couvreur's octave (ftp://ftp.mathworks.com/pub/contrib/v5/signal/octave.tar) has filterbank stuff. Of course the plotting doesn't work, but with a bit of fiddling, you can get, 1/3 octave and 1 octave filter banks to work. | |||
*Mathworks signal processing contributions directories for Matlab 4 (http://www.mathworks.com/support/ftp/signalssv4.shtml) and Matlab 5 (http://www.mathworks.com/support/ftp/signalssv5.shtml) | |||
*University of Vienna's Linear Time-Frequency Toolbox (http://www.univie.ac.at/nuhag-php/ltfat) | |||
The following used to be available: | |||
*Kuo, et. al.'s Speech Signal Processing and Recognition tools (SSPR). A number of the other tools are archived at the same site (http://www.eeng.dcu.ie/~speech5/matspeech.html). | |||
Other Software: | |||
*ESPS has been open sourced (BSD license) and is available at http://www.speech.kth.se/software/. Finally we will have a decent pitch tracker! | |||
