Audio Truncated

I recorded a session today, but when I went to edit it there was a problem with the audio. The Audio appears to be on the same track as the screen capture. Additionally, there are points where the audio gets garbled for a few seconds and when it comes back it is like 10 minutes further in the presentation (i.e. 10 minutes of audio was smashed into 5 seconds). The screen capture continues as normal (does not jump 10 minutes ahead and the audio is now WAY out of sync with the video) and when the audio runs out the screen capture stops (about 25% through the presentation). Just to test it, it tried slowing down the audio in the messed up sections, but it is not actually speed up, it is just digital noise. Has anyone seen this before? I realize this particular recording is a lost cause but I would prefer to avoid loosing anything in the future.

Let's establish what you have there; you recorded using Camtasia (version #?) and the resulting file (trec = audio/video) is acting this way on your Camtasia editing timeline? How long is the recording?

It is possible to split the audio from the video; by your description the audio is behaving as if it was VBR (variable bit rate) but this is usually external clips from iPhones and such. If it was me I would export the audio to examine it separately to see if it could be recovered and sync'd back up to your screen clip.

When you are recording you do have sufficient space to hold the files as they are being recorded?
