DAQ with multichannel soundcard

[Franz Graf]

Hi

I want to use a multichannel soundcard for the acquisition of 8 microphon
signals with LabVIEW. Has anyone experience with multichannel soundcards
connected with LabVIEW. Is there a workaround?

Thanks for all helpful suggestions!

Franz,

The only thing I can suggest for this is to see if the different channels may be registered as different devices. Try them one at a time using the examples to record on different channels.

As I don't have (or have never heard of) a multichannel sound card, I can't advise you on the compatability with LabVIEW.

I can however suggest that a DSA card may be an option if this doesn't work. NI has some pretty good DSA cards with great resolution (16 bits and higher) and sample rates that are probably higher than the soundcard you are using.

If you don't have the budget, the quality is good enough, and you can get it to work, go for it.

Good luck, and please post your results. It helps everyone if we all know the answer to questions like this
.

Franz,

Do you have any type of driver for the sound card? The NI-DAQ VIs will probably not work for this card, so you will not to make calls from some sort of driver. For instance, if you have a dll for it, you could use the Code Interface Node to access the DLL and use LabVIEW to communicate with your card.

LabVIEW has native Sound VIs. They can address the sound card, but only one input line unless they are declared as different devices in Windows, which may be the case.

NI DAQ will not work with this sound card, as it is not a data acquisition device, and I sincerely doubt that there are drivers for it.
