Thank you Matt
I believe it has some of the stuff that I want to build. But something is
missing - and something is there that I prefere not to have (audio mixing).
And maybe Asio4All has some of the same.

Seems like this comes up a lot - doesn't Virtual Audio Cable do what you
want?

Dear group members,
Questions from a fresh member. I want to make a solution that does the
following on XP and Vista:
1) Appears as a sound card driver in the control panel and in audio players.
2) Has a user interface where the user chooses the real sound card and API
to use (WDM, MME, Asio, DirectSound, Wasapi etc). The open source library
Port Audio will be used to stream waveformatextensible audio streams - with
or without the waveformatextensible header.
3) Receives uncoded audio when selected as the driver.
4) Does some signal processing (DSP). A lot of RAM and a lot of CPU will be
used in certain cases. This is the main purpose of the solution.
5) Has a user interface where the user can start, stop, change the signal
processing. And other things.
6) Ports the audio to real sound card drivers by using open source library
Port Audio.
7) Keeps the audio stream bit-perfect exept for the intended DSP. System
requirements should be taken care of by the choosen sound card and audio
API.
The solution doesn't have to be able to play from multiple sources
simultaneously.
Similar functionality does exist in the form of VST plugins and DirectX
plugins, but the plugin strategy has serious limitations and problems for a
lot of users.
Best regards
