Join Anastasia McCune for an in-depth discussion in this video Editing audio within Captivate, part of Captivate Advanced Techniques.
- In this lesson, we're going to see how you can edit audio files directly in Captivate. In the last lesson, we recorded a short voiceover that intentionally had some errors in it. Let's work on editing that audio now. So, the audio in question is attached to slide 2, the product selection slide. I'll click to Slide 2 and there's multiple ways we can open the audio editing interface. I'll show you two. You could click on the audio badge that looks like a speaker underneath the slide and you can choose Edit. Or you could go to the audio menu and then choose Edit, and then from there choose Slide.
The sound waveform appears here in the slide audio box. There's this zoom slider so we can zoom in and out on the waveform and I'll zoom out so we can see the entire thing. Let's play the audio so we have a good idea of what needs to be edited. - (coughing) Please make a selection. Click finish when you are done viewing the products. - So, the bit at the beginning where I clear my throat needs to go. I need to remove everything from about here back to the beginning.
I can select parts of the audio that I want to remove by clicking and dragging. Now, I'll simply click the delete button. And that's it. The sound it gone. There's also a bit in the middle here where I hit my hand against the table. I'll select that part of the waveform and we can play just that highlighted section to make sure that we've got it. Right, so instead of just cutting this out, which is a choice, I'm instead going to choose insert silence by pressing this icon here. Notice the waveform. The timing hasn't changed but the sound has been replaced by silence.
So, I'll click to the beginning of the waveform and play the entire thing once more just to hear the total effect. - Please make a selection. Click finished when you are done viewing the products. - It sounds pretty good except that I think the pause in the middle between the two phrases is just a little too long. So, I'l select just a bit of that and delete it. I'll also cut off some of the end where there's no sound. So, you can see that this basic type of editing can probably get you a long way. Notice you also have Cut, Copy, and Paste options available as well.
You can also automatically adjust the volume of your audio. Because I calibrated my audio before I recorded the volume is pretty good. But sometimes you do want to just make your audio a little bit louder or softer. So, I'm gonna click on adjust volume to open those controls. So, you could do a global volume adjustment here by clicking on the slider and moving it up or down. That'll make the volume of the entire waveform louder or softer. You could also choose to normalize the audio.
That let's Captivate make decisions for you about selecting the best volume throughout the recording. Or you could choose dynamics that would reduce loud sections but leave the quieter sections alone. You'll want to explore how each of these settings affect your audio that you recorded with your microphone. For now, I'm just gonna cancel out of this box. But Captivate also offers the option of saving this audio file out of your project that way you can use it elsewhere or maybe edit it in an audio editing program that offers more choices than what Captivate does.
If you need to do something like filter out background noise or mix two tracks together a dedicated audio editing program is what you'd need. To export your audio out, click the Podcast button. You can save your recording as either a WAV or an MP3. I'm not gonna do this right now so I'll cancel. Back in the audio editing window, I'm gonna click Save to save the edits and then close. Now, you can also export out your audio by right clicking it in the library and choosing Export.
So, notice on the timeline that the audio has gotten quite a bit shorter. It used to be longer. So, we need to readjust our slide timing to account for this. I'm gonna grab the right-hand edge of the slide duration and drag it back to the end of the audio. On this slide, all the visual elements should appear right at the start of the slide and stay visible for the entire slide duration. It looks like everything just happens to line up that way so we're finished here but if you need to make adjustments to yours go ahead and do that.
With that, we can save our project and why not preview the entire thing so we can hear our audio in action? So, we see the title slide. Now, we'll click to continue. - Please make a selection. Click finished when you are done viewing the products. - And there's our slide audio. So, making mistakes while you're recording is normal. Now, you've seen how to see audio editing tools within Captivate in order to create professional sounding audio right at your own computer.
