Hi Skillz,
We have a dedicated module, LabVIEW DSP, which can run on the Speedy-33. Otherwise, you will not be able to get your edition of LabVIEW to execute code on that processor. You can program for your PC's or Mac's sound card, but since it is not a real-time processor it will not be as good at tracking.
Here is a link to the DSP module:
