Lovely Curves

  1. Apr 27, 2005 #1
    This more of a maths question rather than a physics one, but I do remember doing something similar is my physics course.

    Basically I trying to write a fade in and fade out function
    for a volume control but I am stuck on the maths part. Thats where I
    need you.

    I've tryed a linear fade, but that does not sound good

    so y = volume (0-100)
    and x = time (0.5)

    time is fixed to 0.5sec but can alter slightly if needed

    volume will be one value from 0 to 100, but I dont know what the
    volume will be until the function is needed

    ok, I'm using

    to=0 to 475 (stepping by 25)
    and alpha as 1.01
    Vo is set at 50

    The values that I am getting are 16-45(rounded up)
    is this correct?
