Hi there,
I lnow nothing about audio/video programmming. I got an internet application
that switches ports all the time while receiving streaming audio. There are
multiple streams as far as i can see with a port monitor. I want to record
this. My primitive thinking brought me to the idea that creating a custom
mixer application could do the trick. Or … Any ideas are welcome.

PS. I searched the net and can not find any program that can do this kind of
thing (record audio output). Is it possible at all?

Well, there are no special programs for that, since any audio
recording program can do it, provided you have a full duplex sound
card (all reasonably modern cards are, AFAIK), or, if all else fails,
two sound cards and a cable.
What you do is just open up the input/record controls in the mixer,
select the wave output channel for recording and adjust the recording
level. Then you can record as usual with any audio recording program,
such as the one that comes with Windows. Most soundcards seem to come
with one or two such programs as well. Some even include serious
sound editing software, such as SoundForge and CoolEdit. Usually
"Light Editions" and things like that, but still h-lluva’ lot more
powerful than that toy that comes with Windows.
Note that this method means it’s the sound card that dictates the
quality. Older cards usually have analog mixers, which means you’re
actually recording the output from the DAC, using the ADC, whereas on
most modern cards, setting the mixer up as described above has the
card bypass the analog domain entirely. However, cards like SB Live!
and Audigy still resample everything to/from a fixed sample rate.
(Always 48 kHz in the case of Live! cards, for example.) This may
reduce quality slightly if you’re using some other sample rate than
the card’s “native” rate.
