Hello,
Recently I made a VAC (virtual audio cable) by doing an Audio Device Driver
providing virtual output and input (to route an application to another :
typically a player to a recorder). It's in pre-release there
www.vb-vac.com... I'm waiting for certificate to make 64 bit version.
REM for Tim: the biggest challenge has been to make a real time format
converter to be able to accept whatever buffer (with whatever format) in the
workflow (also it seems there is a behavior difference between 2000/XP where
the client application can change the device format, and Vista/W7/W8 where
the device format seems to be not modified by the client application but
converted and delivered by windows in the current device format (kMixer ?
with a bad sound quality btw).
Question 1 :
Since Windows Vista, it seems the Recording device cannot provide more than
2 channels : is it a official system limitation ?
is there workaround to provide for example 8 channels in a recording device
(under W7/W8) ?
Question 2:
Does it make sense today to accept more than 8 channels in an audio device
driver ? I mean is the system or/and is there window player application
managing that ?
Thanks by advance
