If your audio signal is in form of a numeric array or a waveform cluster, to amplify it, just muliply it with a numeric value Smiley Wink

like in this VI

For some reason I'm not being able to use the multiply function to control the gain of my audio output on this VI (when I try to attach a constant value to the multiplier, it displays some sort of array control). Any ideas?

LabVIEW 7.1 is currently installed on my system, so could not open your vi
could you please post a picture of your block diagram??

Greetings!

       You should be able to pull up a numeric constant from the numeric pallete in the block diagram and wire it to the multiply. Please refer attached image. It willl result in a 1 D array of waveform.

Thanks and hope this helps
