Greetings,

Newbie needs help to loop output of an 8-bit mono wav file to an analog output channel on a PCI-6723 using DAQmx.

Hi Toad,

Thanks for your post.

By using some of the sound VIs in LabVIEW it is possible to extract the raw waveform information in array form, and also obtain the sampling information.

With this info you should be able to scale down the array values and write them to your DAQ card. The sampling information returned from the file can then be used to set up your sample generation rate on your DAQ card.

Please see the attached example VI. You will be able to use this as a starting point, for your code. I hope this helps.

Thanks,
