Try to modify your sampling rate, either in your recordings settings, or in the Windows system. My impression from the symptoms that you describe is that the audio is recorded at a certain sampling rate, but reported as a lower sampling rate, or not at all.

Does Audacity play the audio too slow, too?.

Is this the same sampling rate as being reported by MediaInfo?

On the left side of each track you find the sampling rate, too.

Then, I would import your video file into Audacity (which imports only the audio, of course).

in which sampling rate your audio was recorded.

if the interleave of the audio (the starting offset) is set correctly.

if the durations of the video and the audio is the same or not,.

You should check your recorded video with MediaInfo. I am using BisonCap to record, the software that came with the computer. I am saving the recording to a file on a ramdisk, so I don't think the hard drive is the problem. It is a 2 Megapixel camera that can record at 15 fps. The webcam is a BisonCam NB Pro integrated into the laptop. I can fix this problem after the recording (laboriously), but I want to have the recording work properly in the first place. (A still image remains in the video player while the voice continues.) The audio track continues for about ten or so seconds after the video component has finished. When I watch the video afterwards, the sounId is delayed by about a second. I clap my hands at the start of the video. I can actually get lip synch if I s-p-e-a-k l-i-k-e t-h-i-s.

Whilst I am making the recording, I can see the video that is being captured being displayed on the laptop monitor. The sound starts arriving about a second after it should do and gets increasingly delayed. avi file afterwards, the audio and video are out of step.

I make a 30 second recording using a webcam on a laptop.
