audioclips and playstopped

[Phil Davis]

Hi Richard,

Here's one way:

  play audioclip "xyz"
  wait until the sound is done
  go next cd

Or...

on startAudio
  play audioclip "xyz"
  send "checkAudio" to me in 0 seconds
end startAudio


on checkAudio
  if the sound is done then
    go next cd
  else
    send "checkAudio" to me in 10 ticks
  end if
end checkAudio
