Sudden static! Cannot find the solution!

Hello and good day! 

I am having issues with my audio. It was working fine the night prior, but in the morning as I went to do more recording, it had all this static. 

I tried getting a new XLR cord, and that didn't work. I tried a new mic, that didn't work. I tried downloading new drivers and that also didn't work. I updated adobe audition and still no dice. The only thing I haven't tried is getting a new audio interface because I though I should reach out before making more blind purchases. I will attach a screen shot of before and after. both are taken in the same room with the same sound proofing and are raw.

 

The mic I am using is an AT2035 

audio interface is a Behringer u-phoria UM2 

 

If anyone can help me out, it would be very grateful! 

 

Thanks

I know it might sound a bit strange, but can you post an audio example? It's often a lot easier to detect the cause of a problem that way when it comes to noises off...

For sure, thank you for getting back me! 

 

here are the samples.

The one named  "test sample post issue" is what I just recorded. The gain is in the middle at the beginning, I then turned it all the way down and then all the way up and back down.  odd that the noise was still there with the gain all the way down. 

The other sample is from a prior recording, raw and unedited.

 

Thanks again!

It doesn't sound like static - it just sounds like a high noise level. There doesn't seem to be much about the UM2 that would cause this - except for one thing. It has two inputs, and the second one is a high-gain guitar input. If you have nothing plugged into this, but the gain control was accidentally turned right up, there's a chance that this might add the extra preamp noise to your signal.

 

The only other thing I can think of involves the way your system is powered. You haven't said what sort of computer you've got. If it's a laptop, are you running it from its battery, or from the mains? There are some strange things that can occasionally happen when it's supplied from a wall wart, that magically disappear when it's entirely battery powered.

 

If none of that applies, then you'll have to see if you can borrow another interface from somewhere and find out if the same thing happens.

Have you checked the settings of the input controls? Not the XLR one specifically - that will alter the mic gain. It's the other one that you need to make sure is turned down, just to eliminate the possibility that this is where the noise is being introduced.

Yes, I turned down all the levels and the same backround noise was being made. I also just straight up unplugged the mic and all other mics attatched (the only other being on my web cam) and it still had that same noise. So odd.

On the face of it, it sounds like a faulty interface then - unfortunately not exactly unknown with Behringer products...

The problem is fixed! It was the audio interface! But of course it's the very last thing I try that fixes the issue. 

 

Thanks for all your help!

Hello! I'm not sure if you're still looking for a solution, not that this will for sure work, but I just switched the USB port I had it in. Now, when it happens, I just switch it to another port, and it stops. I have no idea what caused it to happen. Seems rather random. I had this same issue before, where the solution was changing my audio driver, but from what I remember, I ended up reformatting my system, and it fixed the issue as well. My most recent issue, which was not being able to hear playback from audition, was never fixed. They just told me to use the beta and keep an eye out for the next update. 

I know its not much, but I hope this helps!
