Hello! To use your Audiophile 2496 sound card with LabVIEW the first thing you are going to need is a driver from the manufacturer. Most manufacturers already have a driver that works with LabVIEW or at least a driver written in C that then you can call from LabVIEW using Call Library Function Nodes.
To store the two stereo inputs you can keep using 2D arrays. This time you will have two, one for each stereo input. Another option is to use a 3D array where you will be able to switch between stereo inputs (first dimension), left and right (second dimension), and different samples (third dimension).
