Making a fake soundcard

[johnman]

I would like to make a fake soundcard driver, so i can capture the sound from every program with my application (wavewizard). The idea is that when an application plays the sound to my fake soundcard, i can capture it without any quality loss.

The problem is that im unknow in the area of making drivers. I read that i need ddk (driver development kit) from ms, but i wonder if i can do it without the ddk. I already have acces to msdn, which also includes some documentation of the ddk, but AFAIK there arent any examples included with this msdn. I read there is an example soundcard driver that can be used as a startingpoint, but i cant find it in the msdn installation directory.

Am i trying to do the impossible? Or is it absolutely necessary to pay ms 200 bucks for the ddk before i can make a simple driver. If someone has some code i can use, it would be greatly appreciated :cool: .

Perhaps some OSS audio-capturing applications have a null soundcard module you could study?

Try this program.

Virtual Audio Cable. I have used it a lot and it does what you want.

Almost all OSS software is using the GPL license. wavewizard is not GPL so i cant use it. But i will have a look anyway to see what i can find.

Virtual Audio Cable is excatly the kind of functionality i want, but i want to make it for wavewizard. Its not something i need for myself because i can already do it using my own soundcards drivers :).


EDIT
In my search i found someone suggesting to looak @ "Installable Driver" in psdk.
Im checking it out now....
