Generate Decimated Sound

[troy.perales]

Hi--

I am using an NI 5640 card to capture a radio signal. Since the signal is coming in at a faster rate than the sound card can handle, I have changed the format of the sound write output to 48828.125 S/s and 4096 # of samples/chn. The sound signal coming in is decmiated to take every 8th value. The sound output almost works. the only problem is it plays everything 8th data value of sound and it repeats it until a new value comes in.

I am posting hear since this is an aspect of LabVIEW moreso than the NI 5640 card.

Thank you

Troy

Have you tried testing your algorithm in just LV first without your hardware?  That is, use some of the sound card shipping examples to see if you are using the proper sampling rates and decimating successfully?
