Join Anastasia McCune for an in-depth discussion in this video Audio splitting, part of Flash CC 2015 New Features.
- The current release of Flash Professional allows you a quick and easy way to split audio files on the Timeline into two. Now here's what I mean. I'm gonna hit Ctrl-Enter to test our sample file here. To keep things interesting, it has an animation of a person driving a car which is suddenly stopped by a giant monkey jumping in front of the car. Now what happens after that in the story is anyone's guess. We're gonna add some audio to this to see the new Audio Split feature. Now adding audio into Flash is the same as it's always been.
So I'm just gonna go to the File menu and choose Import and Import to Library. I'm gonna find the car sound in the exercise files and click Open. Here in my Library, our car sound appears. So here on our Timeline we have a sound layer. I'm gonna click frame one and I'm gonna drag and drop car.wav to the stage and we can see the waveform appear here in the Timeline. I'm gonna click Play underneath the Timeline so we can hear what that sound is like. (car engine revving) (brakes screeching) So, it starts out sounding like the car is accelerating and then there's a screeching sound near the end as the brakes are hit.
You can kind of see where that screech starts in the waveform. It's here around frame 54 and 55. So the timing of the accelerating part of the audio I think is OK. But the tires screeching to a halt part could probably be better if it happened just a little bit later on down the Timeline, maybe about frame 60 since that matches up with some of the other action going on here on the Timeline. So, up until now, there might be a couple ways you would approach splitting up that sound.
You could edit that sound in something like Adobe Audition and break it into two sounds there, re-import them both, and place them separately on the Timeline. Another approach might involve blank keyframes and multiple instances of the sound and editing the sound envelope for each iteration of the sound. Or maybe you have some other approach you'd use. The Audio Split feature is pretty fast to implement, so here we go. The first thing to check is that the sound is set to stream. So you do that by clicking on the keyframe the sound is attached to.
So in our case, that's frame one. Then in the Property inspector, make sure that in this Sync dropdown it is set to Stream. If it's not set to Stream, the next step will not be available. This is only for streaming sounds. So I want to split my sound right about frame 54. So I'm gonna select that frame, and I'm gonna right-click and choose Split Audio. So, you can see a new keyframe has been added. Now, if we play the Timeline again, the sound plays pretty much exactly the same as it did before.
(car engine revving) (brakes screeching) However, it really has been split into two, and you'll see that in just a moment. To have some space between sound one and sound two, I'm just gonna right-click on frame 53 and choose Insert Blank KeyFrame. So there we have a little space between the two sounds and I'm gonna drag the start of this second sound here on frame 54, I'm gonna drag that down to frame 60. So now we've really split the sound.
I'm going to go ahead and play the sound again. (car engine revving) (brakes screeching) So that's good. I think that timing seems to make a little more sense. So, one thing to note is that by splitting the audio, you really do have two instances of the sound, as you just saw. However, the first instance is not really truncated. If you want to adjust the position of this blank keyframe here, you could do so just by sliding it down the Timeline.
And you'll see that the rest of the waveform that was originally there is in fact still there. So if we listen to this, (car engine revving) (brakes screeching) OK, so we heard the screeching sound twice. I don't think that makes much sense in the instance of this project, but having that feature might work for one of your projects. So I'm just gonna drag our blank keyframe back to frame 54 and call it good. So, the Audio Splitting option basically offers you a different and probably faster workflow for splitting up sounds on the Timeline.
Just remember that to access the split audio feature, the sound has to be set to stream in the Property inspector.
