How do I make a Windows Driver?

Question

hi I want to learn how to make windows drivers for a research I'm doing which involves making a generic audio driver that supports digital output like Dolby Digital Live by leveraging cpu instead of custom hardware.

unfortunately I can't find proper documentations and when I Installed WDK I realized I haven't the slightest clue how windows drivers work and what's the difference between kernel and user drivers and which should I use.

can you point me in the right direction?

Answer 1

See MSDN docs, like https://learn.microsoft.com/en-us/windows-hardware/drivers/audio/roadmap-for-developing-wdm-audio-drivers

Answer 2

The audio driver uses APO, a technology called Windows Audio Processing Object. Please refer to the following documents.

A SYSVAD sample can help you as below.

I recently used this information and samples to develop a driver for a gaming headset with digital 3D audio effects.
