connecting two soundcards in software

Hi,

Does anyone konw of a utility that will let me monitor the input on one soundcard on the output of a second soundcard? I thought Windows Sound recorder would do that, but it won't, unless I record and playback.

I can't physically connect the two cards, as one is a virtual one (bluetooth audio).

Thanks,
Pim

I'm sure there's a program that musos use to connect various programs together to using virtual patchcords, or something like that. Other than that, an app to transfer the wavein from one card and play it through the waveout of the other.

Unbelieveably, Steinberg Wavelab 4 does NOT support this, which I find hard to believe.
