Adobe Presenter lets you add narration, music, step‑by‑step instructions, or almost any sound to your projects. You can use audio to provide instructions or to emphasize key points in the presentation. In general, sound can be as individual and flexible as any other presentation component.
You can use audio in Adobe Presenter presentations in various ways. For example, you can use Adobe Presenter to:
- Add sound to an individual slide
- Add special sounds to quizzes for correct and incorrect answers
Audio files included in presentations are saved within the audio assets folder. The PPCX file contains metadata about audio files. Presentations with a PPC file must be converted to PPCX to enable Adobe Presenter features. If you move or copy presentation files or the assets folder, be sure to include the audio assets folder. (Moving or copying the audio assets folder without the PPCX file may lead to problems.)
After you add audio to a presentation, you can do some simple audio edits such as:
- Synchronize the timing with other content, such as animations. For example, if your presentation contains PowerPoint animations, such as text that “flies in,” you can synchronize the animations with the audio. For more information, see Add animation, image, and Flash (SWF) files.
- Add silent periods to audio files.
- Normalize audio for all slides so that the sound level is consistent.
Files imported in WAV format are converted to mp3 when a presentation is published. Final published presentations only play mp3 files.
You can quickly add existing WAV or mp3 format audio files to a presentation. Simply import the files and use them as opening music, narration, or instructions.
- Select the audio file and click Open. (You can add multiple files. If you select more than one, the first audio file is added to the slide you selected in step 3, the next file to the slide immediately following, and so on.)
Do not exceed 100 minutes of audio per individual slide in a presentation.
In addition to adding existing audio files, you can also record your own audio files to use in Adobe Presenter presentations. Recorded files are saved in mp3 format. Follow these tips to ensure that you are recording the highest-quality audio possible.
After you have acquired the necessary audio recording equipment, set it up properly. If you are just using a microphone, plug the microphone into the computer and start recording. Alternatively, you can plug the microphone into a mixer or stand-alone preamplifier. And then, plug the output of that device into your computer sound card’s “line in.” Plug the headphones into your computer. Then, set the volume on the mixer or preamplifier. Begin speaking to test the volume levels, and carefully raise the volume until it shows just under zero. (Using a preamplifier and line-in socket is optional.)
You can open the software application that controls the sound card. (In most Windows operating systems, you can find sound settings by clicking Start in the lower-left corner and selecting Settings > Control Panel > Sounds.) When you select the recording source (line in), you can adjust the volume to 100%. If you are using a mixer or stand-alone preamplifier, the actual recording level can be controlled from there.
After starting your audio recording software, you can change the settings as necessary. Mixers and preamplifiers don’t have sound-level controls, so you rely on the meters when recording. While recording, ensure that you do not exceed zero on the meters. Else the sound gets distorted.
Positioning your microphone correctly can make a big difference in the finished audio file. First, get as close as possible to the microphone (within 4–6 inches) so that you avoid recording any other nearby sounds. 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, to 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. By doing so, you 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 can adjust the speed later by using your audio recording software. Finally, keep in mind that you don’t have to get everything right the first time. You can listen and evaluate each recording and rerecord, if necessary.
Editing sound is like editing text. Listen carefully to your recording, delete any extraneous sounds, and then use the options available in your software to polish the sound. Add any music or sound effects you require, but make sure to save your audio track in the correct format (mp3 or WAV).
After you have added the audio to the presentation, listen to it again. Finally, it helps to ask others to preview the presentation file. If necessary, you can edit the audio again, on a per‑slide basis.
Having the right audio equipment makes a significant difference in the quality of recorded audio. Surprisingly, basic audio equipment can be relatively inexpensive; your equipment could include some if not all of the following:
Computer with a sound card
The sound card installed in your computer acts as a digital recorder for audio.
If possible, avoid using the internal microphone that comes with most computers. Use a professional-quality 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 computer’s sound card probably includes a preamplifier, but it’s 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 you can adjust their volumes independently. Stand-alone preamplifiers can be better than mixers at filtering out unwanted noises.
The speakers that came with your computer are probably good enough for listening to any audio you record. For best results, check the specifications of your speakers and use the highest-quality speakers possible.
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.
A wide range of recording software is available, including Adobe Audition®. Important software features include editing capabilities (to fix mistakes), music and sound-effect options, and the capability to create the file format you require (such as mp3 or WAV).
You need a quiet place to record. Try closing doors, turning off any unnecessary computer equipment, turning off or lowering lights that might be making noise, and turning off phone ringers, beepers, and pagers. Also, tell coworkers that recording is in progress.
Audio files present the common challenge of balancing quality against size. The higher the sound quality, the larger the file size. When working with audio, think of your users’ connection speed. In the best development case, experiment to find the optimal balance between sound quality and file size for your users.
- Select an audio quality level. Remember that a higher quality level results in a larger audio file size.
- (Optional) If your presentation contains SWF files on consecutive slides, select Disable Preloading Of Embedded Flash Content. This option prevents a second SWF file from beginning to play before a first SWF file is finished.
To publish a presentation without including any audio files, deselect Publish Audio.
If you are recording audio for a presentation, you can either use a microphone or the line‑in option that is usually included with an external audio device, such as a tape deck or stereo amplifier.
- (Optional) Select the Always Prompt To Set Microphone Level Before Recording option if you want to calibrate the microphone before each recording session. Calibrating is useful if you use different microphones or if you record in different environments (for example, a quiet room versus an area with background noise).
If you are recording audio for a presentation, set the microphone or recording device to the correct recording level. This process is called calibrating the recording device. Adobe Presenter can detect optimal microphone and recording sensitivity levels automatically.
Adobe Presenter must detect your recording device before calibrating it. Before you calibrate, check that your recording device is connected to your computer properly and is turned on.
If you have created slide notes in PowerPoint, you can import the notes into the script window in the Record Audio dialog box. Importing notes is useful if you want to use the slide notes as a script when recording an audio file as voice‑over narration.
If you have a microphone connected to your computer, you can record audio for inclusion in a slide. You can use audio for many types of narration or instruction.
At times, you may need to record and add some audio to a specific location within a presentation. (To record audio, you must have a microphone or recording device plugged into your computer.)
- Click the location within the waveform to which you want to add new, recorded audio. For example, if you have an audio file playing on slide 1 and you need to add audio at the start, click the beginning of the audio file on slide 1. You can add audio to any location on the waveform, even a location that does not currently have audio.
To locate the exact point in a waveform, click at an approximate point where you want to record and click the play icon. When you reach the point where you want to add new audio, click pause.
After previewing your presentation, you can edit the timing of PowerPoint animations to better synchronize with added audio files. For example, if you have a slide with bulleted text items that fly in, you can adjust the timing so that the audio track matches the action of the animated text.
Note: The Sync Audio dialog box synchronizes PowerPoint “On mouse click” animations only. In contrast, timed animations use the timing set in the Custom Animation dialog box in PowerPoint. Animations can only be synchronized with audio files, not video files.
As the audio plays, click the Animation arrow to synchronize the timing of the animation with the audio. If the slide contains another animation, the Animation arrow is displayed again in the Sync Audio dialog box. Click the Change Timings icon again and click the Animation arrow to synchronize the timing. Repeat this step for all animations on the slide.
As the audio plays, click the Animation arrow to synchronize the timing of the animation with the audio. If the slide contains another animation, the Animation arrow is displayed again in the Sync Audio dialog box. Click again and click the Animation arrow to synchronize the timing. Repeat this step for all animations on the slide.
You can edit the audio in your presentation at any time. You can listen to an audio file, insert silence, adjust volume, and change other options.
A. Insert marker B. Slide divider and Red marker line C. Waveform D. Record audio button E. Play/Pause audio button
- Use the buttons and menu options to make any necessary edits. You can cut and paste sections of the audio file, insert periods of silence to lengthen the audio file, adjust volume, import a different audio file, and more.
To paste information from the clipboard. (For example, if you select a section of the audio file, and then click Cut or Copy, Adobe Presenter places the selected audio on the clipboard. You can then click Paste to place the audio back into any location within the audio file.)
To specify the selected location, in seconds, within an individual slide on the waveform. For example, if you are working with a slide that is 5 seconds long and you click in the middle of the slide on the waveform, this playhead area displays approximately 00:00:02.500.
A quick way to listen to the audio you added to a presentation is to play the slide show directly from within the Edit Audio dialog box. Click in the Edit Audio dialog box and then click play ().
You can add a period of silence to any audio file that is part of a Adobe Presenter presentation. This feature is useful in the following situations:
If you import an audio file and must synchronize the audio with slides
If you need to make an existing audio file work in a presentation without having to edit the audio extensively
If you have inserted an FLV file with audio, such as sidebar video of a speaker, into a presentation and want to synchronize the FLV file audio with slides
You can adjust the volume of audio files included in your presentations. After adjusting the volume, preview the presentation to see if the sound level is acceptable.
Adobe Presenter lets you edit the timing of audio files after you record or import them. Having control over the timing of audio files gives you the ability to use audio files of different lengths and incorporate them smoothly into presentations.
After you record or import an audio file, the file appears as a waveform in the Edit Audio dialog box. If your presentation contains multiple audio files, you can see which audio files are assigned to specific slides.
In the Edit Audio dialog box, Adobe Presenter displays any audio files incorporated into the presentation as waveforms. Slide numbers above the waveform show exactly how the audio files are currently distributed across the slides. Adobe Presenter lets you import or create an audio file and then distribute that audio file across multiple slides.
At times, during audio narration, you may want to explain or present content that is on another slide. In such cases, you can use the Go To Slide marker to jump to the required slide.
If you want the presentation to automatically stop at a specific point and wait for the user to continue by clicking play in the Playbar, do the following:
- In the Edit Audio dialog box, click the waveform, and then click Zoom In or Zoom Out in the tool bar. (Alternatively, click in the waveform and roll your mouse wheel to zoom in and out).
The scale at which you are viewing the waveform is shown in the Scale information box in the top-right corner of the dialog box.
After you have added audio files to your presentation, you can use the Edit Audio dialog box to cut or copy entire audio files or portions of audio files and paste them in a new location.
