You know it's not an end-fire microphone, right? You talk across the top of it with the Blue logo facing you.

Try this code in Audacity's Nyquist Prompt ...
It will look like this ...

Yeah, i'm using my mic in cardioid mode and it's facing me right. On pic i just place it as far as i can from any sound sources for tests.

HELP! I have this same problem......except my noise is WAY louder. And to make things worse, my yeti was working absolutely fine with my new build for months. Then this week I went a few days without using the yeti, plugged it back in and BAM. This sound persists even when i mute the mic. So if I go to recording options, then listen to this device, the sound is there whether or not the mic is muted. It sounds similar to the 2m sample from in this post but much louder.
Why would it come out of nowhere? I didn't add anything or change anything about the computer. It's a brand new build I put together 3 months ago.

I'm having the exact same problem as the first guy. The sound squeal is identical and I'm wondering if you fixed it? Any explanation would be helpful! Thanks!

I had the same problem when I put a USB extension cable between the computer and yeti. Using the original yeti cable only prevents the noise so it does seem to confirm it is induced. I have a screened cable so will try thay and report back.

I've got the Blue Yeti Pro. When I first got it, it wasn't making the electronic noise, now it is. I've tried installing it on my Win8.1 and Win7 systems but the result is the same. Audacity recently updated the software, not sure if that has anything to do with it. Prior to the latest release, there was a software release for Win7 and a separate one for Win8 and Win8.1 systems.
This is the before sound:

Normal sound, no electronic noise; the background whine is what is audible to human ears in the room.
Fast forward a week, and this is what is recorded:

I'm pretty sure the RotJ recording was made AFTER I installed my new ax1500i, and was working fine. This means that my reassembly of my PC shouldn't be the issue: cord contact, which socket on my power strip various things are plugged into, USB ports have all been pretty much the same since last week. I've tried plugging the mic in with a different USB cable, tried all but two of the USB ports (it was clear after the first six it wasn't going to make a difference), changed gain, mic mode (cardiod, stereo, omni, bidirectional), input/output levels in the Blue software, latency (extra safe to minimal), bit rate, ASIO buffer, Windows recording device levels, and the headphone volume knob.
When I plug a set of headphones into the monitor jack, there is no electronic noise (it shouldn't, it's an analog jack). For some reason digital recording seemed to slightly clear up when I did that, maybe because of static dissipation or grounding or something, but only very slightly. I have my PSU connected to the surge suppressor's grounded jack. Since isolators have been confirmed to not do anything, can anyone say whether or not powered USB hubs have been effective?
I'm not going to bother mentioning which motherboard, GPU, earbuds, or monitor I have, since at one time there was no issue, and now there suddenly is.

I think the problem is fixed. I think the thing that fixed it was switching which socket my PSU was plugged into on my surge protector. After I did that, the noise was mostly gone. To make sure it stayed gone, I clipped the ends off of an RJ11 cable, stripped it down to the bare copper, tied one end to a metal air intake vent, and tied the other end around a case screw. The noise audible in the recording is background noise audible to the human ear.

The audio interference is back for apparently no reason. No devices have changed sockets since the last time, no change in cabling or wires, with the same audio problems as before. I'm going to try switching outlets again.

I can now confirm that a powered USB hub is not the solution. I bought an $18 Wrench SuperSpeed 7. Plugged it in, still getting the electronic noise and other audio recording artifacts.

Any ideas? I've heard people say on other forums it might be the micro USB port on the mic being of poor quality and having an incomplete connection. I just bought mine and it's been doing this ever since I first got it. The other possibility is voltage on the system, but the artifacts follow the mic to other systems. Could be the motherboard's USB hub not supporting the power of multiple devices, but I've tried isolating it down to a few devices and didn't see any difference. Could be use of an SSD and something to do with page files or other software glitches, but I've tried it on a system with Win7 and without an SSD. I almost feel like forgetting the mic and going with an XLR to USB converter, but if it's the system, that's not going to make any difference.
