DECtalk software or hardware?
Ed is right, the fixed-point math can result in a +- 1 bit oscillation..
though I admit I never noticed it when I was working with DECtalk back
in the 1990s (if I did, I would have fixed it!)
Good to hear from you Ed as well.. hope things are going as well as then
can..
