#This script generates a fade-in and fade-out to the selected Sound
# using the cosine-function squared in [0, 0.5*pi]
# the variable 't' (next line) determines the window of the fading
t = 0.01
Formula... if x < 't' then self * (1- (cos(0.5 * pi * (x/'t'))^2))  else self fi
ft = Get finishing time
Formula... if (x > ('ft' - 't')) then self * (1- (cos((0.5*pi * (( 'ft' - x )/'t')))^2)) else self fi
