C++/VB - Antialiasing with DirectSound

Hi @ all,

is there a method in DirectSound for Antialiasing captured sound?

Best Regards

Capture at the native device rate where possible to prevent aliasing.

DirectSound has no such methods.  You have to communicate directly with the
driver and query for the hardware output rates as the kernel streaming
sample does.  It's not exactly easy.  Even still the DirectSound system can
already have the device open at a higher rate causing unexpected
resampling.  The only 100% way is to not use DirectSound but instead to use
Kernel Streaming (XP only?), ASIO (limited hardware support), or WASAPI
(Vista only).

But if I Package them under Vista I get an "unable to find entry point " in the MSVCRT.dll when installing on 2000 or XP machines.

out the OS is the wrong version, the GetwinVersion( ) is available for this purpose. However, XP includes various "compatability modes" and older windows versions included the WINVER.EXE application.

I do not see any reason that MS could not have added a flag of choose how to run under each version. The name of the function is With Win7 XP support it is an actual VM copy of XP that is running. Compat. mode is not that. I do not know exactly what it And that is the problem. If Windows is going to tell me I am on XP when I am really on Vista, then it needs to run exactly as it would
