Joining 2 wav files: will this result in audio sync probs?

[mojo2185]

Let me explain the process that I'm following right now.
I had 2 avi files, they were splits of a whole movie, so are the same codecs, bitrate, etc. First, I extracted the audio of both files using virtual dub, and converted the audio to NTSC (from pal) using BeSweet. I then took the video streams from both avi files and combined them back into 1 file (also made the vid streams NTSC). So now I have 1 movie only stream, and 2 audio streams. How can I join the audio files back together? Also, will doing this result in audio sync problems when it comes time to encode using TMPGEnc?

Thanks

Use a program like Gold Wave to save the audio to the format you want after it joins the audio for you. If you find the audio not in synch then, you can add silence, or time warp the file to bring it back in synch.

I actually had Cool Edit, and it worked perfectly (joining the audio like you said). It looks like the video is in sync, so no need to add silence or warp for now.

Thanks for your help!
