How to cut of some frequency

[spitfir3]

Hello!

My question is, how to cut off some frequency (machine noise). The problem is, im recording some sound, but have a noise in the background, which is always there, becouse of the machinerie around the test object. So i want to cut off (in example) frequency from 1300-1500Hz. How do i do that?

Im using labview 2010 & sound&vibration toolkit. I found some expres .vi's which cuts frequencies in example from 1000Hz up or down, but no .vi is there which cuts in betwen.

Hi!

You should create a bandstop filter. There are some examples on that in this forum. You can also check out and maybe modify this: https://decibel.ni.com/content/blogs/Simon/2010/06/16/world-cup-2010--filtering-the-annoying-vuvuzel...

P.s sorry for the long link. Opera seems to only let me create one link per post.
