Hi Alvie !
First of all thank you for you taking the time for such a thorough answer: really appreciated
I've used Excel in order to calculate the sine sample values, and your last formula:
int(128+100*sin($n*2*pi/2048))
works as expected , giving values between 28 and 228, with 'n' from '0' to '2047'.
The problem in Hamster Book's formula seems to be the '+1' after the sine (sine(n*PI()/1024)+1)*100), that you have ignored in your formula, that makes the multiplier of '100' to be between '0' and '2', instead between '-1' and '1', giving as a result a different range of values.
Now to my Papilio !
Thanks again.
