We tried this program with our sound system at the church. We are using the stock motherboard sound card with simple patch cords from the sanctuary sound board. From the sound board "phones" out jack to the computer microphone input and the computer speaker output to one of the sound board microphone input jacks. Works perfectly with about 1MB per minute of sound at 48000Mhz. This is such a simple program: record, stop, play, save/search for file. It couldn't be easier and more efficient. 5 stars:*****
