Slide with soundin and image: audio size issues

[David McFarlane]

Sylvain,

This all looks good to me, so I have no idea why it does not work for 
you -- in my experience, with SoundIn Buffer Size set to 1000 and 
other settings such as in your example, I get a full 1000 ms of sound 
recording.  Using a Sleep inline for the ITI should make no 
difference, but by now you should have done that exercise for 
yourself (and reported back here with your results).  So something 
else must be going on, or maybe someone else here has a clue.  (Note 
BTW that End Capture Action did not work in EP2.0.8.90, see 
http://www.pstnet.com/forum/Topic5473-12-1.aspx .)

So you should just submit this to PST Web Support, see stock reminder below.
