Peter,

I don't have Acousmographe but I did have a play around with the  
sonogram programs that I do have.

I was able to make movies of scrolling mono sonograms using Amadeus  
Pro (inexpensive and good) and stereo sonograms in Izotope RX (more  
expensive).  The cursor in Audacity was too jumpy to bother with, and  
Raven would not scroll at all.  I used a screen capture program  
called iShow U.

YouTube uploading is new to me, but I tried it out.  I could get the  
movie of the sonogram to upload but there was no sound at all, so I  
don't know what I did wrong.

Then I tried uploading the same movies to my website, and this worked  
just fine.  You will need Quicktime to see them.

Let me know if you can view both sonograms OK, and can hear the sound.

cheers,
