Gidday,

I hope this is an appropriate place to post this request.  If anyone knows
of any other news groups I could also post it, let me know.

Basically, my situation is this...

At my work (Computer Based Education section of the Queensland University
of Technology) we are starting a project in Language Learning using
Videodiscs as a primary resource.  At some stage in the game we will be
getting students to repeat things that have been said on the videodisk
(or stuff played on a soundblaster card), and they will be able to here
themselves back to compare.

At some point (though this is not planned yet) we may be looking at
displaying some kind of frequency curve (if you know what I mean) of what
they say so they can compare that to what they heard (the frequency curve 
of which would also be displayed).  Note, I am not talking about a graphic
representation of the sound wave as that would appear as just so much
jibberish.

Does anyone know of any software to provide this (of necessity running
under Windows and supporting the SoundBlaster16 card), or any simple way
of getting it done?  I need to know now what is available so when the time
comes to move I can move.

Thanks,

Tim.
