Chapter 10: Audio
You can add audio to your project by doing one of the following:
• Narrating the movie into a microphone as you record the project.
• Importing audio files into the movie after you complete recording it.
• Converting slide notes to speech using the Convert to Speech option.
You can add audio to any of the following in Adobe Captivate:
• Slides
• Project
• Objects
The audio file plays when the slide, project, or object appears in the movie.
See www.adobe.com/go/learn_cpaudio_en for a detailed overview of audio in Adobe Captivate.
To get started using audio in your project, see www.adobe.com/go/learn_audiotutorial_en.
Recording in sync
Add sync sound (synchronized sound recording) to your projects by narrating the movie into a microphone as you
record it. The movie is recorded in the mono format.
Recording equipment
Having the right audio equipment makes a big difference in the quality of recorded audio.
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 sound
card probably includes a preamplifier, but it is most likely of poor quality. 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. You can
change some of your speaker settings if required. However, if you are working on a laptop, use standard desktop
computer speakers instead of the built-in laptop speakers.
Headphones Headphones are important because when the microphone is on, speakers can cause distracting feedback.
Additionally, it is best to use closed-ear headphones that prevent leaking sound (which can be picked up by the
microphone).
Media players Any software that can play audio files on your system.
