Adobe Presenter 6

Set audio recording quality

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 file size and the lower the quality. Presenter lets you control the way sound is recorded and compressed based upon your input and output requirements.

Creating audio in Presenter is essentially a two‑part process: you record audio in WAV format and then Presenter converts the WAV file into an MP3 file.

Of course, when working with audio, you must keep your users’ connection speed in mind. If a user is likely to access the Presenter presentation by using a dial‑up modem, use a higher compression and lower sampling rate, such as 56 Kbps. However, if you are distributing the presentation on a CD‑ROM, you can use a lower compression and higher sampling rate, such as 144 Kbps. In the best development case, you should experiment to find the optimal balance between sound quality and file size for your users.

  1. In PowerPoint, open a presentation (PPT file).
  2. From the Adobe Presenter menu, select Preferences.
  3. Select the Quality tab.
  4. Select an audio quality level. Remember that a higher quality level results in a larger audio file size. (To publish the presentation without including any audio files, select Publish without audio.)
  5. (Optional) If you think users might view your presentation on computers with slow connections speeds, select Require Slides To Download Completely Before Playback. If this option is enabled, it will take longer for the presentation to start, but the slides will play smoothly after the presentation begins.
  6. (Optional) If your presentation contains Flash movies (for example, Adobe Captivate content) on consecutive slides, select Disable preloading of embedded Flash movies. This option prevents a second SWF file from beginning to play before a first SWF file is finished.
  7. Click OK.
