Preferences - Audio Device Tab

Choose a driver type from the drop-down list.

• ASIO: Allows you to choose a specific low-latency ASIO device from the Default stereo and front playback device drop-down list.

• Direct Sound Surround Mapper: When you're working with a 5.1 surround project and a surround-capable sound card, this setting uses the default Windows audio device to send 5.1-surround audio to your sound card.

• Microsoft Sound Mapper: Uses the default Windows audio device for playback and recording.

  If your video preview device supports audio playback (please see the Details box on the Preview Device tab for device status), you can play your project audio through your video preview device using the Microsoft Sound Mapper:

  1. Configure your video preview device on the Preview Device tab in the Preferences dialog.

  2. Select the Audio Device tab in the Preferences dialog and choose Microsoft Sound Mapper from the Audio device type drop-down list.

  3. Select the Use audio-capable preview device check box.

     When you preview your project with Video Preview on External Monitor enabled, audio will be routed through your video preview device. When Video Preview on External Monitor is not enabled, audio will play through your default audio device.

• Windows Classic Wave Driver: Allows you to choose a specific audio device from the Default stereo and front playback device drop-down list.

Click the Advanced button to change settings for the selected device.

Choose the device that you want to use for playing stereo sound data and the front-left and -right channels of a 5.1 surround project.

Selecting the Microsoft Sound Mapper allows the operating system to select an appropriate device to use for the current sound data.

NOTE If you have selected Microsoft Sound Mapper, you will not be able to assign busses to different devices. For more information, see Routing busses

Choose the device that you want to use for playing the rear channels of a 5.1 surround project.

Choose the device that you want to use for playing the center and low-frequency effect channels of a 5.1 surround project.

Drag the slider to adjust the amount of buffering that occurs before starting playback.

The larger the number, the more buffering occurs during playback. This value must be as low as possible without gapping. To set it, start at .25 and play back a typical song. Move some of the track faders. If the playback gaps at all, try increasing this slider in small increments until the gapping goes away.

If you simply cannot get playback to be free of gapping, you need to either decrease the number of tracks you are trying to play simultaneously, install more RAM in your computer so you can increase buffering, buy a faster access hard drive, or minimize the number of DirectX plug-ins you are trying to use simultaneously.

Select this checkbox and drag the Track buffering slider if you want to adjust the amount of audio that is prerendered ahead of the cursor position.

When the checkbox is selected, a separate processing thread is used to render audio from tracks. On multiprocessor or multicore computers, a thread will be created for each logical processor, resulting in improved track counts, improved performance with lower latency, and faster audio rendering.

When the checkbox is cleared, a single processing thread is used to render audio from tracks and busses.

Choose the device that you want to use for recording sound data.

Selecting the Microsoft Sound Mapper allows the operating system to select an appropriate device to use for the current sound data.

Select the checkbox to automatically compensate for offset between the time you initiate recording and when your sound card starts recording.

Clear the checkbox and drag the User Offset slider to specify an offset value (hold Ctrl while dragging for fine adjustment).

Clicking this button opens the Advanced Audio Preferences dialog. For more information, see Advanced Audio Configuration
