Adjust audio quality

Quickly optimize settings with the Audio Setup Wizard

  1. Select Meeting > Audio Setup Wizard.
  2. Follow the onscreen instructions to optimize audio quality. If a dialog box appears requesting access to your camera and microphone, click Allow.

Set advanced audio options

  1. Choose Meeting > Preferences, and then click Audio in the left pane.
  2. Select Use Enhanced Audio to automatically cancel echoes, control microphone volume, and suppress noise. Deselect this option if you have trouble with audio quality.
  3. For Acoustic Echo Cancellation Mode, select one of the following:
    Note: The Adobe Connect Add‑in must be installed to use these options.
    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.

  4. Select Automatic Gain Control to enable your microphone volume to adjust automatically in response to changes in voice level. Deselect this option if audio volume fluctuates unpredictably.
  5. For Audio Quality, choose the highest setting that does not degrade sound:
    Fast
    Provides the fastest performance but the lowest audio quality. (Use this option for systems with slower CPUs.)

    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. 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 to reduce the amount of noise that the microphone picks up. Deselect this option to make the microphone more sensitive.

    • 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).

  6. Select Use Speex Codec to take advantage of this VOIP-optimized technology. (This option requires attendees to install the Adobe Connect Add-in.) Options range from Fast for fastest performance and poorest quality, to Best for slowest performance and best quality.
