Help! Blue Yeti high pitch noise

[TheTalkingKeyboard]

Noise Reduction works to an extent, although it's not practical as I use my Blue Yeti for video recordings and such, making reduction less practical.

I've attached an example that I just recorded. I've had this noise across almost 3 years of using the mic. I've changed every part of my computer hardware and have recorded in numerous environments.

Better mic? The Blue Yeti seems enough

As someone else said prior to this post dying for a year, the noise is only there whenever the microphone is being captured, so a simple solution I thought of would be to power the mic via a wall plug USB and use a male to male 3.5mm jack to export audio and input into my motherboard mic port, although I've not tried yet.

Thanks for any help

I've been trying to buy a Yeti on the cheap by bidding on eBay, but even the beat-up ones get pushed up beyond my budgie.

As a practical matter if you have The Yeti Curse (data whine), it's fatal. We've never found an external device that can be added which will reliably suppress the noise. I think I mentioned the wall-powered USB hub possibility? Some of those hubs are worse than the disease.

Noise Reduction fails for an odd psycho-acoustic reason. The whine has about the same pitch as "Babies Screaming on a Jet." It's impossible to ignore and by the time you convince Noise Reduction to do an effective job, the effect is starting to affect the quality of voice.

There is such a thing as Yeti-Pro. At double the cost, they probably filled in all the technical holes that the plain Yeti had. We've never had a complaint about one of them.

One of the eBay submissions claimed a "Yeti Professional." Wait. Which microphone is this?

Crossing the headphone out of the Yeti with the Mic-In of the computer can give you headaches. You may end up running the headphone volume right at the very bottom of its range so as not to overload the computer. That and the computer's Mic-Pre has never won any awards for good, quiet operation.

If you have a modern computer, you have one of those single-socket headset connections with Headphone out and Microphone in on the same plug. You should make sure you get the right adapter if you go that route.

As in the above multiple forum chapters, many people have looked for solutions, few found them.

Since all this hole-poking is happening right in the exact middle of the ear's maximum sensitivity range (~1KHz to 4KHz) I would expect to be able to hear that filter working, further, this is a post-production solution and the poster's applications include real-time tasks.

The phrase "Yeti Curse" was not chosen lightly.

It's official. We got a complaint about a Yeti Pro. It was dead right out of the box.

I know nothing at all about the purchase or the circumstances, but it failed some very basic "life" tests. I assume the poster is going to try and exchange it or get a refund. They didn't say any of those things.

What works for me:

Increase the gain and lower the recording level in computer to less than 20.
