Adobe Audition 3.0

Set driver properties for a sound card

To improve the performance of ASIO and DirectSound cards, optimize driver properties.

  1. Choose Edit > Audio Hardware Setup, and click Control Panel.
  2. Do one of the following, and then click OK.

    • In an ASIO control panel provided by the sound card manufacturer, set driver options. (The options available will be different than those described below. For more information, consult the documentation for the sound card.)

      Note: By default, Adobe Audition controls the ASIO sound card while playing or monitoring audio. If you want to access the card in another application, select Release ASIO Driver In Background.

    • In the DirectSound Full Duplex Setup control panel, set the following options:

      Device check boxes
      Use the check boxes under Direct Sound Output Ports and Direct Sound Input Ports to turn devices on or off. When a port is deselected, it is not available as a port option in the Audio Hardware Setup dialog box.

      Buffer Size (Samples)
      Usually, the default settings work well for both playback (DirectSound Output Ports) and recording (DirectSound Input Ports), but some sound cards may require different settings. If you hear skips or dropouts in playback, you can adjust buffer size: Double‑click the Buffer Size numerical entry for an input or output device, and type a new value.

      Port Order
      If the selected device includes more than one port, click the Move Up or Move Down button to change the order of the ports for that device.

      Sync Reference
      Specify whether you want the DirectSound Input or the DirectSound Output to set the master clock.

      Full Duplex
      Select this to enable Adobe Audition to record an audio track while another one plays back, if the sound card is capable of doing so.

      Start Input First
      This determines the order in which Adobe Audition starts the sound card playback (in) and record (out) ports in a multitrack environment. Select this option only if you have an older sound card that doesn’t support full duplexing.
