Audio in full duplex

I’m working on an application that requires full duplex audio, which means
I can sample from the microphone while outputting to the speaker, at the
same time. It also has to be cross platform, specifaclly win32. As it is
I’m not using sdl and the program works fine, but I don’t want to face the
problem of dealing with win32 directly (directsound, is it?). It’d be
perfect if sdl could handle the audio…

Please cc dash at on any replies, I’m not following the dev list
regularly anymore. Thanks!
