yea, its a pitch ratio-linear - so if you keep increasing by integers
(2,3,4,5,etc..) you will transpose up the harmonic series.

you'll have to calculate the pitch ratio accordingly if you are thinking
inpitch class terms..

SubjectCD formats and does diskin take linear octave input
Hello All,
                I know very little about wave formats and so am
              puzzled by the fact that my CDs sometimes will not
              be recognized by some CD players. This AM one failed to
              be recognized in a friend's player, yet when I checked
              the disk on Fischer, Sony, and JVC, sytems at a local
              emporium, the CD played back fine. Consequently, I'm a
              little befuddled. (I burn the CDs with a Windows.PCM.wav
              format.)
                On another topic I wanted to inquire about the pitch 
              change parameter of diskin. I did succeed in getting it
              to play the example through a string of 12 pitch classes
              with accepteble results, but when I call it into a piece
              I get it 2 octaves below, and find it tricky to get on 
              pitch.
              I've found some kludgey ways around the problem but suspect
              that I've missed something that's in the black box of      
              diskin. It seems reasonable to use linear octave notation
              but I don't know what diskin expects; the manual says
              sig*2 for ocatve and sig*.5 for lower oct. etc. buuuuut.
              Anyway, Luck to all!!!!!!!!!!!!!
