86 Chapter 5: Adding Audio and Video
Adding existing audio
You can quickly add audio to a project if you already have audio files in WAV or MP3 format.
Simply import the files and use them as opening music, background narration, instructions, or
any other purposes.
Note: When you import WAV files into Adobe Captivate projects, Adobe Captivate automatically
converts them to MP3 files when you publish the project.
To add audio to a slide:
1.
Open an Adobe Captivate project.
2.
From any view, select the slide to which you want to add audio.
3.
From the Audio menu, select Import.
The Import Audio dialog box appears.
Note: Adobe Captivate contains a gallery that has buttons, sounds, and animations (in SWF
format) for you to use in your projects. By default, the gallery is stored in the following location
when you install Adobe Captivate: C:\Program Files\Adobe\Adobe Captivate 2\Gallery.
4.
Navigate to the audio file (WAV or MP3) you want to add to the slide, select the audio file, and
click Open.
5.
(Optional) If the playing time of the audio file is longer than the playing time of the slide, a
dialog box appears asking if you would like to edit slide timing. Click Yes to open the Edit
Audio Timing dialog box.
Equipment for recording audio
Having the right audio equipment makes a big difference in the quality of recorded audio.
Surprisingly, basic audio equipment can be relatively inexpensive.
Computer with sound card
The sound card installed with your computer acts as a digital
recorder for audio.
Microphone If possible, avoid using the inexpensive microphone packaged with your
computer. Also, use a proper microphone cable and a stand to hold the microphone while you are
recording.
Microphone preamplifier
A preamplifier boosts the signal of the microphone. The microphone
input of your computer's sound card probably includes a preamplifier, but it is most likely a poor
quality one. When purchasing a preamplifier, you can choose a small mixer or a stand-alone
version. Mixers let you connect several microphones and devices to one location and adjust their
volumes independently. Stand-alone preamplifiers are considered better than mixers at filtering
out unwanted noises.
Speakers
The speakers that came with your computer are probably good enough for recording
purposes, although you may want to change some of your speaker settings. However, if you are
working on a laptop, you must use standard desktop computer speakers instead of the built-in
laptop speakers.
Note: In Microsoft Windows operating systems, you can usually find speaker (sound) settings by
clicking Start in the lower left corner and selecting Settings > Control Panel > Sounds.
