Audacity Forum

I heard back from hifimeDIY and using my Frying Mosquitoes sound clip as an example, they said it should not be difficult to get rid of that with the little USB Isolator adapter. Mine is in shipping.

As we go.

Did you have any luck? I found this post via some angry Googling shortly after buying my Yeti, and have been waiting (eagerly!) to hear how it turned out for you.

I have my isolator here, but haven't had time to mess with it. I have the additional problem of only creating the problem by using a special combination of equipment. Unlike you, I didn't just plug a microphone in and it started whining. I had to create the problem. Now I have to create the problem again and then make sure I can get rid of it.

The up side of all this is flynwill knows how to take it apart if I want to change the electronics around.

No joy in mudville.

I connected one of my Startech USB HeadSet adapters (mono microphone and stereo headphone) and got the whine sound in the recording. I put the USB isolator in the system and got almost no improvement.

There is a sound change, but it's only 2.0dB by actual measurement. You can't hear a change that small. I had to go looking for it with the Audacity measuring tools to make sure it did anything at all.

So no, we're not going to get you out of trouble with a small USB isolator/adapter.

Sorry,

Argh! The quest continues.

Thank you for giving it a shot and updating everyone.

There is one other "device" available that has a very good chance of eliminating the whine. But now we're back in the land of soldering irons. It comes as a naked circuit board wrapped in static tissue and you are expected to make a little box for it and design, buy and install a separate power supply.

All that is workable if you have your own drill press, but most people buy a Yeti assuming it's going to be plug, play, and make a podcast.

It's a joke on another venue that people contract to create a podcast and then unwrap the Yeti the day before the show is due. Scary, but not that unusual. Cellphones have spoiled everybody rotten. There was one contributor that tried to do the performance into his iPad. Everybody knows there's an app for that.

In addition to not curing the "normal" problem, I think I found a second way to get the whine different from the one we know about. So I made it worse.

Have a happy day.

Just to cover it, did you contact either the supplier/store or Blue? There is the possibility that neither one knows this is happening.

What device is that, out of curiosity? I may get super ambitious...

That's about what I did!

Marketing: "Hey, can you order this mic for us, it's cheap and really good and we want to use it for some quick recordings."
Me: "Sure thing, order placed!"
mic arrives
Marketing: "Teehee, we don't actually need it. But keep it around, we might use it!"
into the closet it goes...until 3 months later when someone remembers we have it and asks for it

And here we are.

I haven't yet, primarily because I read a few stories that more or less said "that's the way it is and Blue says it's your machine". I will, though, and see if they have recommendations or ideas.

I think the suppliers are depending on the Yeti users not talking to each other.

"Does your Yeti fail ACX AudioBook because of that whiney noise? Mine does, too!"
"Hey, wait. Mine does that!!"
"No foolin'? I wondered about that stupid noise."

And etc.

We know what it is. These devices use the pure battery voltage in the USB cable to run everything. The problem is, it's not pure. It frequently has trash running around on it and that's the trash that gets into your show. None of the higher end microphones, mixers and adapters do this because they all have electronics to clean up the trash. That's the electronics that cost a little more money.

I use a rule of thumb that if the device says "48 volt Phantom Power" in the instructions, it's probably fine. The same electronics that makes the 48 volts, cleans up the trash. It's harder with microphones. There you have to go with historical data: Nobody ever complains about a top quality Doobli-Doo® Microphone, but there are lots of complaints from Yeti owners.

Blue pushes you off to a computer problem because technically, it's true, but you're not likely to buy a new machine just to get your $130 usd Yeti to work, and it may not help if you do. So that leaves you in a hole. It's actually worse than you think, because ACX would just as soon you not use Noise Reduction, and they said so.



I'm looking for the links.

So for only about the cost of your microphone (after adding power supply, cables and shipping and not counting assembly and testing), you can have a working Yeti.

Neither of us bought one of these yet. $48 usd is a little steep for a casual purchase, particularly since neither of us has sound damage in a show. I had to go out of my way to make the whine and flynwill had to use scientific instruments to find his.

Here's a finished one in Texas, for 20 bucks:
