Bob, Beeing a low level "close-to-the-hardware" hacker, I am allergic to M$ and window$ but I somehow managed to write a simple SDR program for window$ using Portaudio for soundcard interface. You may wish to have a look at my code which is available at http://web.telia.com/~u33233109/saqrx/saqrx.html You can dig into the Portaudio source code to see how to use the win32 waveXX calls. 73 Johan SM6LKM
