Hello Simon,
how can I write audio to the Virtual Audio Cable if I have the samples in a
C program?
The most well-known virtual audio device solutions (Virtual Audio
Cable and VB-Cable) are standard WDM Kernel Streaming drivers. They
expose standard KS interfaces on which the system builds its
higher-level ones (WASAPI, MME, DirectSound, AudioGraph etc.). Without
special measures, applications cannot distinguish these virtual audio
devices from real hardware ones.
So your application can use any suitable Windows audio interface to
interact with virtual audio devices. MME is the simplest but less
efficient, WASAPI is the intermediate, ans KS is most efficient but
most complicated.
Regards,
Eugene
