Auricon 2.2+ Manual

 

  Under Windows 2000 it has been observed that sometimes the mixer control settings are not 

preserved after rebooting. When this happens the settings revert to their defaults. Microsoft 
has fixed this in later versions.

 

 

  Windows  8,  7,  Server  2012,  Server  2008-R2,  Server  2008,  Vista,  XP,  Server  2003  and 

Windows  2000  Service  Pack  3  support  true  24  and  32  bit  playback.  In  earlier  versions  of 
Windows 2000, extended bit depth audio was accepted by the wave and DirectSound API’s 
but  truncated  internally  to  16  bits.  24  bit  (or  32  bit)  capture  is  supported  on  all  Windows 
versions.

 

 

  In  all  versions  prior  to  Windows  Vista,  Microsoft’s  sampling  rate  converter,  which  is 

automatically  switched  in  when  playing  multiple  audio  streams  of  differing  sampling  rates 
through  a  single  physical  output,  is  slightly  inaccurate  when  doing  some  conversions 
(notably 11.025kHz and 22.05kHz to or from 48kHz). 

 

 

  Audio capture splitting (running multiple capture applications from a single audio source) is 

not supported on Windows 2000.

 

 

  Hardware mixing of multiple input sources for recording is not supported under Windows 8, 

7, Vista or corresponding server versions, as each input source appears as a discrete audio 
endpoint device.
