Let's say in DirectWave, I want to change the pitch tune using Type in value option, what number should I input if I want to change the pitch to -100 cents (1 semitone lower)?

Seems like there is some sort of black magic behind this option and using it required calculation and formula which I could not find any documentation about it.

  • Probably just math, not magic. :) What units are used to specify the pitch? If it’s Hertz (Hz) and you want to lower the current value by 100 cents (1 equal temperament semitone), divide the Hz by the 12th root of 2, which is about 1.059463094359295. – trw Mar 1 at 16:57
  • Thanks for the comment, I don't know the unit, Hint panel shows Cents as unit. I tried 1.059463094359295 and pitch changed to -1200. it's crazy, user have to do this calc! if they can not do this weird calc, why they added this option? – Mehdi Dehghani Mar 1 at 17:25
  • Can you provide a screenshot with the original value? If it’s correcting your input to -1200, then it’s probably a change in pitch specified in cents, not an absolute pitch. In this case, if you wanted 1 semitone lower, just enter -100. – trw Mar 1 at 19:25
  • The initial value is zero, and trust me, I tried many options, include simple ones (like -100), I tried %, 0.1, ... (before post the question here), not of them doesn't work – Mehdi Dehghani Mar 2 at 4:47
  • @trw and yes, (in DirectWave) 1 pitch = 100 cents. btw DirectWave and pitch is an example here. I don't know there is one global formula for Type in value option or every parameter have specific formula – Mehdi Dehghani Mar 2 at 9:25
