Looping Sounds

Flash’s sound-looping parameter allows you to repeat sounds without adding another instance of the sound to a frame. Type a value in the Loop field in the sound area (the right side) of the Frame Property Inspector. Flash plays the sound the specified number of times. You can loop event sounds and streaming sounds. The sound’s Sync parameter applies to the whole set of repeated sounds.

To set a Loop value:

1.
Create a 15-frame Flash document with a short event sound in Keyframe 1.

This exercise uses the sound called Camera Shutter 35mm SLR from Flash’s com on library of sounds.

2.
In the Timeline, select Frame 1.

3.
In the sound area of the Frame Property Inspector, enter 3 in the Loop field (Figure 14.32).

Figure 14.32. Typing a value in the Loop field tells Flash how many times to play the sound.


Flash extends the sound’s waveform by stringing together three copies of it. In the Timeline, Flash displays as much of the extended waveform as will fit in the available frames (Figure 14.33).

Figure 14.33. When Loop is set to 0, Flash displays just the original waveform in the Timeline (top). When Lo p is set to 3, Flash displays as much of the repeated waveform as there is room for (bottom).
