Setactorsoundpitch
setactorsoundpitch <actor#> <sound#> <pitchoffset>
Can be used to change the pitch of a playing sound. Command was added to r2104 by helixhorned.
The pitch offset has the same meaning as the definesound pitch range endpoints, i.e. the units are 1/100th of a semitone. Note that just like the random pitch offset, increasing the pitch makes the sound duration shorter (and vice versa).
