Audio may be recorded and played back if a tab is recorded using the continuous recording mode. Audio is never recorded when using the triggered recording modes.
udio is always recorded from the camera’s built-in microphone when using a DirectShow video driver to capture DV video (as from an IEEE-1394 or FireWire® camera). To record audio when using a Legacy VfW video capture driver, you must select the Audio button before recording begins.
When a video is recorded with audio, a small “loudspeaker” icon will appear in the preview window when you move the cursor over a video’s tab. To hear this audio, you must select the Audio button before video playback begins.
