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.
Computer with sound card
The sound card installed with your computer acts as a digital recorder for audio.
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.
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.
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 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).
A wide range of recording software is available. Important software features include editing functionality (to fix mistakes), music and sound effect options, and the capability to create the file format you require (such as mp3 or WAV).
After you have acquired the necessary audio equipment, the most important action you can take before recording is an obvious one: find a quiet place to record. Try closing doors, turning off any unnecessary computer equipment, turning off or lowering lights, turning off phone ringers, beepers, and pagers. Inform your coworkers that recording is in progress.
After you have acquired the necessary audio recording equipment, ensure that it is set up properly. First, plug your microphone into your mixer or preamplifier, and then plug the output of that device into your computer sound card's “line in.” Plug your headphones into your computer. Then, set the volume on your mixer or preamplifier. Begin speaking to test the volume levels, and carefully raise the volume until it shows just under zero.
Sound card settings
Open the software application that controls the sound card. The sound settings are located in the Control Panel. Select the recording source (Line In) and adjust the volume to 100%.
You control the actual recording level with your mixer or preamplifier.
Audio recording software settings
Start your audio recording software. Change the settings as necessary. Note that mixers and preamplifiers do not have sound-level controls, so you rely on the meters when recording. While recording, ensure that you do not exceed zero on the meters, or the sound will be distorted.
Positioning your microphone correctly can make a big difference in the finished audio file. First, get close to the microphone (within 4 to 6 inches), so any other nearby sounds have less chance of being recorded. Don't speak down to the microphone; instead, position it above your nose and pointed down at your mouth. Finally, position the microphone slightly to the side of your mouth, because this can help soften the sound of the letters S and P.
Have a glass of water nearby so you can avoid “dry mouth.” Before recording, turn away from the microphone, take a deep breath, exhale, take another deep breath, open your mouth, turn back toward the microphone, and start speaking. This trick can eliminate breathing and lip-smacking sounds frequently recorded at the beginning of audio tracks. Speak slowly and carefully. You may feel that you are speaking artificially slowly, but you should be able to adjust the speed later by using your audio recording software. Finally, bear in mind that you don't have to get everything right the first time. You can listen and evaluate each recording and rerecord if required.
Editing sound is similar to editing text. Listen carefully to your recording. Delete any extraneous sounds and then use the options available in your software to polish the track. Add any music or sound effects you require. Make sure you save your audio track in the correct format (mp3 or WAV files).
Adding audio files to Adobe Captivate
When you are finished recording the audio file, add it to the Adobe Captivate project.
After you add the audio to the Adobe Captivate project, listen to it again. Play the project as users normally would. Finally, ask others to preview the Adobe Captivate SWF/audio file. If necessary, edit the audio file again.
Audio files present the common challenge of balancing quality against size. The higher the sound quality, the larger the file size. The more you compress a sound and the lower the sampling rate, the smaller the size and lower the quality. Adobe Captivate lets you control the way sound is recorded and compressed based upon your input and output requirements.
Creating audio in Adobe Captivate is essentially a two-part process. You record audio in WAV format, and then Adobe Captivate converts the WAV file into an mp3 file. When files are in WAV format, they have a degree of flexibility. You can edit and adjust them “downward,” compressing them into mp3 files uniquely tailored to their playback scenario.
When working with audio, keep your users in mind. If a user is likely to access the Adobe Captivate project by using a dial-up modem, use a higher compression/lower sampling rate, such as 56 Kbps. However, if you are distributing the project on a CD-ROM, you can use a lower compression/higher sampling rate, such as 144 Kbps. In the best development case, experiment to find the optimal balance between sound quality and file size for your users.
Using Adobe Captivate, you can record an audio file for a single slide, group of slides, or for the entire project.
For slides with unique audio files, the Timeline of the slide is stretched to meet that of the audio file. However, audio files for a project are cut short if they exceed the project Timeline.
Record the audio file for a group of slides starting with the selected one. To finish defining the range of slides included in the group, enter a slide number in the To field of the Record Audio dialog box.
Creates background audio for your project. For details, see Create background audio.
In the Audio dialog box, configure the following according to your preferences:
The recording window displays a Preview panel where you can view the project as the audio gets recorded.
Select this option if you want the file to play until the end of all the selected slides or the end of the project.
Captions and Slide Notes
Use these options when you want to record voice-over narration that matches the caption text or slide note text. Read aloud the text that you have added to these areas when recording audio.
Click the icon to begin recording audio.
Click the icon to play the audio file after you have completed the recording.
Click the icon to stop playing the audio file.
Lets you make the following changes to the audio file:
Select portions of the audio file and copy them.
Delete portions of the audio file.
Export to podcast to save the file in WAV or mp3 format.
Fade In and Fade Out
Set a time, in seconds, for the audio file to fade in and fade out at the beginning and end of the project.
Lower Background Audio Volume On Slides With Additional Audio
Automatically reduces the background audio volume on slides that have individual audio files assigned, such as voice-over narration.
The background audio file replays continuously.
Stop Audio At End Of Project
Stops the background audio when the project ends.
Click to open the Audio Settings dialog box, which lets you set recording device and audio quality.
The Settings dialog box contains the following options:
Audio Input Devices
Specifies the type of device you are using to create audio. The options available in your computer are listed in the menu.
Select the bitrate at which audio encoding must be performed. Select one of the following options based on the audio encoding quality you require:
Constant Bitrate options:
Calibrate Audio Input
Click to display the Calibrate Audio Input dialog box. You are prompted to read a sentence into the recording device if you are using a microphone. Adobe Captivate uses the sample recording to detect optimal recording sensitivity levels. It is important to calibrate your recording device for optimal sound quality.
If you are recording audio for a project, you must set the microphone or recording device to the correct recording level. This process is called calibrating the recording device. Adobe Captivate can detect optimal microphone and recording sensitivity levels automatically.
Adobe Captivate must be able to detect a recording device before trying to calibrate. Check that a microphone or recording device using “line in” is connected to your computer properly and is turned on before calibrating.
Calibration can be manual or automatic. See www.adobe.com/go/learn_calibration_en for a comparison of manual and automatic calibration.
If you have a microphone connected to your computer, you can record audio to be included on a slide. You can use audio for many types of narration or instruction.
You can choose to record narration, system audio, or both (in the patch for subscription and Adobe Software Assurance customers only)
- To record narration, click the narration icon (), and proceed to step 5.
- To record system audio, ensure that the required audio is running on your computer, and click the system audio icon ().
Adobe Captivate lets you record an audio track at the same time you record a new Adobe Captivate project. This can be a very efficient way to create a full-featured project quickly.
The following procedure describes how to record audio while creating an Adobe Captivate project about an application.
Select System Audio to record any audio originating from your computer speakers (in the patch for subscription and Adobe Software Assurance customers only).
After creating the project, you can edit, import, or remove system audio.
This option is disabled on Windows XP as Adobe Captivate does not support recording of system audio on Windows XP.
When you finish recording, press the End key (in Windows) or (Cmd + Enter) on Mac OS to stop recording.
The audio files you recorded are assigned to the correct slide and saved as individual mp3 files. You can view the files in the Library.
If you need to pause the recording of narration, press the Pause/Break key. To restart project recording, press the Pause/Break key again on Windows or Cmd+ F2 on Mac OS.
You can record an audio file to use with buttons, highlight boxes, click boxes, or text entry boxes. Recording audio requires some basic equipment.
