I record using Dxtory and it records speaker output audio and microphone input audio in two different streams. When I try to export it only uses one of the stream either me talking or the game audio. Is there a way to combine these two streams when exporting so that I hear both in my final video?

I don't think so. My question has to do with Virtual Dub. I know that Dxtory exports two audio streams but when I try to compress it in virtual dub I can only select one of the two streams at once. I would like to know if there is any way to combine these two streams within virtual dub and export.

edit:
Here's an example of the two streams I'm talking about

Stream 1 is the game audio
Stream 2 is my microphone
But I can only select one or the other, is there a way to select both?

I think I found a solution although I'm not sure if its the most efficient way. I hadn't noticed that if you right click an avi file in Windows 7 you can extract the audio streams. So I just added my extracted microphone audio stream from my original uncompressed video over the game audio stream using the "Audio from another file..." option in VirtualDub and everything works fine.

You are sure that everything works fine...?
VirtualDub can save only one audio track to AVI container.

Whether you want to save two audio tracks (to AVI container) or... mix two audio tracks in one track?

Well I can hear both audio streams when I save it (which is what I wanted) and since VirtualDub can't export more than one audio stream I guess that it combines any tracks that you manually add using the "Audio from another file.." option to make it into one audio track.

You can use xmedia recode to combine the audio streams and much more. Its a free media transcoder.

Or an audio editor like Audacity or Goldwave.

Virtualdub is not an audio editor.
