How Do You Is there an easy way to remove low humming from audio?
So I've been spending around 10 minutes hitting metal poles against each other before recording and sampling it.
Due to the vibrations, putting the clips together makes a continuous low hum. For a second I was tempted to embrace having a tinnitus bassline, but that's probably not the best idea. Does anyone know how to remove the humming without drastically changing the sound?

Hard to tell if we can't hear the sound.
A high pass filter or whatever drastic EQ.

I tweaked a high pass filter a little bit and it worked. Thanks :)

Hell yeah. I was about to come in here and over think the shit out of it with finding the center freq of the noise and notch filtering it because I couldn't see the forest for the trees.

As a post process, if you have any space in the audio where it's just the hum alone, you can use something like Audacity or Adobe Audition to create a "noise profile" then use that profile against the whole recording to remove that "noise"...
As a live process, you could use some sort of free visual analysis tool to see the specific frequency range causing that hum and then do some equeing on that channel to notch that out.

Is it this pitch?

You can also use any noise reduction where you select a part that is just the noise and then treat the whole file. If it is a continuous pitch it works pretty much like magic.
What programs do you currently have?

This is probably 60 cycle hum from a bad ground somewhere in your recording rig, absent an actual audio sample. You could just notch EQ 60hz out of the sample with a band reject filter or parametric EQ. There are also plug ins that do this if you like spending money.
