[Trlog] voice recorders

[Jim Smith]

Hi Dave,

Not sure what you mean in statement #1.  I routinely run sbdvp with the 
mic plugged into the sound card and the sound card output plugged into 
the patch connector on my MkV.  The mic and recordings coexist just fine 
as evidenced by the laughter produced in a contest which required Q 
number plus a piece of info which never varied.  e.g, 319 Jim BC.  In my 
enthusiasm I many times hit Enter to send the exchange while 
simultaneously saying the Q # .  While this does speed up the response 
it tends to lead to more fills.  

I don't plug the mic into the MkV mic input anymore since I discovered 
that the mic and patch inputs are in parallel.  I discovered this when I 
first started using DVP.  I kept hearing the DVP messages coming from 
some mysterious place.  It turned out that they were coming from the 
(dynamic Heil) mic.

2.  I ran a test with a local.  He couldn't tell the difference between 
sbdvp recordings and live speech via Heil HC4.  I'm careful to make the 
recordings in exactly the same environment as when operating.  

Clicks don't seem to be an issue.  I seem to remember something about 
there being a difference between 16 and 32 bit sound cards or something. 
 Anyway, with my old Creative AWE64 there are no clicks.  I do all my 
recordings using the Goldwave sound editor.  It's marvellous for getting 
everything to have the same loudness.  No doubt others can do this just 
as well.  If you do have clicks, you can use the editor to delete them.

3.  SO2R - no comment.  I'm not there yet.


There was a comment about trickiness of setup.  Nothing particularly 
tricky about sbdvp, just that the documentation isn't all that clear and 
no one has got around to totally fixing it.
