say i want to get the speaker audio stream and record it to wave, how do
i do this.
I want to make a screen recorder with sound activated, I guess getting
the windows screen into a bmp file is a windows command, is this
possible this way also?

I am going to assume on Windows only?
Well, there are two orthogonal issues: one is Vista vs. earlier OSes,
and the other is DRM vs. non-DRM audio.
For example, on Vista or higher, look into
(Windows Audio Session API) in CoreAudio. YOu can easily jack in and do
However, it won’t work with DRMed audio.
On earlier versions of Windows, or with DRMed audio, you have to get
much more exotic. You basically have to build a driver (a filter driver,
I think). Not a quickie type task, that’s certain.
