New sound program

Friends:

I've just posted the newest version of the sound processing program Dora2 a=
t
http://math.uc.edu/~pelikan/Dora/index.html

Dora2  is NOT a sound editor but a collection of tools for visualizing,
annotating and comparing sounds. For example, one thing I use Dora2 for
is to estimate the number of different songs that a bird can sing. This
processes is quite automated in Dora2 which performs the following
procedures more or less automatically

1) Cut a recording of a bird singing into individual songs
2) Make sonograms of the songs
3) Calculate correlations between the sonograms
4) Assign the  songs to different groups (or types)
5) Assemble an html table that displays the different songs arranged
according to type.
6) Report the order in which the song types were sung and a transition
matrix that tells how frequently each song type follows each other type.

An example of the results of this sort of analysis can be viewed at
http://math.uc.edu/~pelikan/Dora/bhvi/bhvi.html

Dora2 is free, comes with JAVA source code, a .jar file and some
documentation. If you try the program I'd sincerely appreciate bug
reports, suggestions for improvements and for additional features to
include.

Also, if you have a recording you'd like to have Dora2 process as above
but don't want to mess with program installation, java, etc. please
email me directly; I'd like to give it a try.

Best regards,

Steve P
