Interleave Two Sounds

#This function requires the 'clip' and 'copy' functions to work.

# Interleaves 2 sounds until the shortest of
# the 2 sounds is done. Takes an integer to designate how long intervals
# should occur.
def interleave(sound, sound2):
  samplelength = input ("Please enter an integer to designate how long intervals should occur: ")
  minLength = min(getLength(sound1) ,getLength(sound2))
  newSound = makeEmptySound(minLength*2)
  numSegments = minLength / sampleLength
  for segment in range (0, numSegments):
    segment1 = clip (sound1, segment*sampleLength, (segment + 1)*samplelength)
    segment2 = clip (sound2, segment*samplelength, (segment + 1)*samplelength)
    copy (segment1, newSound, segment*s(amplelength*2))
    copy (segment2, newSound, segment*(samplelength*2) + samplelength)
