Set up audio broadcasting



Use the Audio Setup wizard to quickly set up and use your audio devices. Use Advanced Settings to make further adjustments to the ways that Acrobat Connect Pro handles audio data. (Using Advanced Settings is recommended only if you have advanced understanding of audio technology.)

Note: Acrobat Connect Pro administrators can change pod, audio, and video settings to adhere to standards for governance. For more information, see Working with compliance and control settings.

Test audio devices and configure settings

  1. Select Meeting > Manage My Settings > Audio Setup Wizard.
  2. Click Next.
  3. On the Sound Output page, click Test.

    A sound sample plays from your speakers or headphone. If you did not hear the sound sample, click Help for more information.

  4. Click Next.
  5. On the Select Microphone page, select your microphone type from the pop‑up menu.
  6. Click Next.
  7. On the Test Microphone page, click Record to test your microphone. (If a dialog box appears requesting access to your camera and microphone, click Allow.)
  8. Click Next.
  9. On the Tune Silence Level page, click Silence. Remain silent until progress is complete.

    Acrobat Connect Pro sets a microphone sound level that compensates for background noise in your environment.

  10. Click Next.
  11. Click Finish.

Set Advanced Settings in the Audio Setup wizard (Windows only)

  1. Select Meeting > Manage My Settings > Audio Setup Wizard.

    The Welcome page of the Audio Setup wizard appears.

  2. Click the Next button to advance to Step 5 of 5 in the Audio Setup Wizard.
  3. Click Advanced Settings.
  4. Make sure Use Enhanced Audio is selected.

    This option turns on automatic audio control, including echo cancellation, microphone volume control, silence detection, and noise suppression. Select this option to use the other Advanced Settings.

  5. For Silence Level, drag the slider to adjust the level. A higher setting results in more sensitivity to silence in an audio broadcast.
  6. For Acoustic Echo Cancellation Mode, select an option to adjust echo cancellation (the Adobe Acrobat Connect Add‑in must be installed to use this option):
    Full Duplex
    Enables multiple users to speak at one time. If echo feedback results, select another option (this option is preferred for most systems).

    Half Duplex
    Enables only one user to speak at a time. Use this option if microphones on your system are unusually sensitive (transmitting unwanted background sound) or if you have poor echo cancellation.

    Headphones
    Optimizes audio settings for use with headphones. This option uses Full Duplex mode, in which multiple users can speak at one time.

    Off
    Disables echo cancellation.

  7. To enable the Acrobat Connect Add‑In to automatically select the optimal Acoustic Echo Cancellation Mode, make sure Auto Sense Acoustic Echo Cancellation Mode (selected by default) is selected.

    If this option is selected, the Add‑In begins with the Mode you selected in step 6 and adjusts the mode based on information from users’ systems. To disable automatic adjustment of AEC mode and use only the mode you selected in step 6, you can deselect this option.

  8. To enable your microphone volume to adjust automatically in response to changes in voice level, make sure Automatic Gain Control (selected by default) is selected. Deselect this option if you experience problems with the audio volume fluctuating unpredictably. Deselecting this option prevents microphone volume from adjusting automatically.
  9. For Audio Quality, select an option to adjust a combination of all audio settings, including silence level, echo cancellation, and gain control, to provide optimized performance. A higher quality setting uses more CPU resources, and therefore slows performance, but provides better audio quality. It is recommended that you use the highest quality setting that does not cause detectable audio degradation on your system. Select one of four settings:
    Fast
    Provides the fastest performance but the lowest audio quality. (This setting uses the fewest CPU resources. Use this option for systems with slower CPUs.)

    Good
    Provides slower performance but better audio quality. (Good is the default setting, recommended for most systems.)

    Best
    Provides the slowest performance but the best audio quality. (Use this option for systems with fast CPUs.)

    Custom
    Enables you to select options for audio quality settings. Use this option if the standard settings do not provide adequate results. Proceed to step 10 to select Custom options.

  10. If you selected Fast, Good, or Best in step 9, proceed to step 11. If you selected Custom in step 9, choose from the following options:
    • For Echo Path, select 128 (the default setting) or 256. The higher setting provides greater suppression of audio feedback. This setting uses more CPU resources and is recommended for systems that don’t use headphones.

    • Select Noise Suppression (selected by default) to reduce the amount of noise that the microphone picks up. Deselect the option to make the microphone more sensitive.

    • For AEC (Acoustic Echo Cancellation), select Fast for the fastest performance and poorest quality, Good for slower performance and better quality, or Best for slowest performance and best quality.

    • Select Non Linear Processing (selected by default) to use non-linear processing for audio data. Deselect the option to use standard processing (and fewer CPU resources).

  11. To override your selections and restore the default Advanced Settings, click Reset to Defaults.
  12. To apply the Advanced Settings and return to the Audio Setup Wizard, click OK. Step 5 of the Audio Setup Wizard appears.
  13. Click Finish to exit the Audio Setup Wizard.
