Hi,
I have done lots of ground work, but could not find any satisfactory
explanation on this. My requirement is like that - i will have an
pseudo audio driver registered. For one of my application (voice chat
application), I will select this driver for audio i/p and o/p.
Application will deliver any incoming voice to the pseudo driver for
audio o/p (in normal case, it would have been given to the sound card
driver in the system). The pseudo audio driver will forward this voice
to somewhere else(lets say X). The pseudo audio driver will get user
voice i/p from X and forward it to the voice chat application (in that
case X is acting as a microphone source).
Initially I was thinking it won't be possible in windows. Then I came
across MSVDM where they have written a driver for storing voice to a
file instead of o/p it to sound card. I was thinking to tweak this for
my purpose. Will it be possible to make this work for our requirement?
Also, I heard a lot about kernel streaming. Do I need to devlop any expertise
on that too.
It will be helpful if you can tell me what are the things I need to
know to develop this driver. I have never worked on audio driver in
windows. Also, I heard there are some bugs in MSVAD which have been fixed. Do
you have any pointers on that?
An early reply will be very much appreciated.
Any pointers or help in this regard will be highly appreciated.
