Making video captures of online gameplay with MSI Afterburner.

The game of course has stereo audio. I find to get stereo audio in the
video captures, I have to start the capture process while I'm still in
the main screen, at the point before I select a particular server.

If I wait until I've gone to the server to start capturing, the audio
captures as mono.

As per above, if I start the capture in the main area, then select the
server and go into the gameplay the capture has stereo sound. Further
once I do it that way I can then start and stop the capture process
while in-game creating multiple avi files and the audio remains stereo
in each avi.

So what's happening? Why would initiating video capture at one point
prior to connecting with a particular server net video with stereo
sound, but going to the same serving and then starting the capture
doesn't provide stereo audio in the avi file?

This happens whether I'm routing audio through Realtek onboard audio
or an Audigy Platinum EX.

Thanks.

Wouldn't this be a question, for the person who wrote "MSI Afterburner" ?

How are we supposed to guess, what logic is present inside that program
(and recorder) ?

There could be a menu in the recorder, with selections like mono
or stereo, and the program could be ignoring its own settings.

Where you able to Google and find any experiences similar to yours ?

MSI Afterburner mono audio

So the very first article I find, has some hints:

"Anyway, I recorded a game of DOTA2 last night after having set
MSI Afterburner to record my headset and microphone. I had
tested this out to make sure it was recording both sources
prior to doing this by just making a short few seconds recording
with some blah blah blah and opening the uncompressed .avi file
in Windows Media Player. I confirmed both sources were recorded."

So is it recording one audio stream, or two ? Some microphones,
they're mono in hardware, which could account for a mono choice
on a microphone channel.

So the recording process, is more complex than it may appear.
The recording may have multiple audio streams. You have to
think carefully, knowing how system sound works, whether
this is possible or not, or the audio might be picked off
from a source other than the one you're thinking of.

"Afterburner 2.3.0 is out...

Multisource audio recording. Now it is possible to record audio from
two independent audio sources (e.g. game audio and microphone sound)
in two independent audio tracks then mix them later in video editing
application (e.g. Sony Vegas PRO) or optionally mix multiple tracks
in realtime during capture
"

You need to discover just how many audio tracks got recorded.
Recording multiple sources would not be common with other
recording applications.

Maybe you could ask the author of the program ? Seems to hang out here ?
