Capturing Audio Seperately

[Germanicus__]

My capture program (WinDVD) captures directly to mpeg for the audio, and for whatever reason the sound quality and volume fluctuates a little. (The reason I'm using WinDVD is that I don't have the time to capture to AVI and convert, and this is the only mpeg-2 capture program I have).

Anyway, I was wondering if it would be possible to simply capture the audio seperately in another program (probably as a wave), convert it to AC3 (as I normally do), and then combine it so that it syncs with my video file?

I would imagine the audio and/or video would have to be trimmed as you wouldn't be able to start the two captures at the same exact moment.

Thanks in advance.

I think audacity (free) will record a wav file....

Most likely the audio will be out of sync if you use another program to capture sound,you`ll have to either stretch or shrink the audio to match the video length so its best you find a capture program that works or fix the audio the way i described without having to capture audio twice,just fix the original audio track.

I tried this once just to see if it worked OK. I used ATI MMc for mpg2 and Audacity for the audio. Technically it worked but trying to sync later on was a bit of a nightmare. I wouldn't recommend it unless you have no option.
