Random Squeaking Noises

No - we released 2.3.0 on 29Sep18 and we’ve had two releases after that with 2.3.2 as the latest release.

Peter.

Sorry. Wrong release.

Back to the volume control. Why are you using it turned down? Did someone post that you needed to do that?

Koz

Back at the sound system. I don’t hear any squeak around “was.” Someone with better hearing may need to listen.

Can you listen on a different computer or sound system?

I was going to go to the known problems Yetis have, but maybe I don’t think that anymore.

Are you listening to the computer for playback or Audacity playback directed into the Yeti’s headphone system?

Are you going through a hub between the Yeti and the computer?

Are you listening to the live performance on headphones plugged into the Yeti?

Koz

Are you sure you’re listening to the exact same sound clip that you posted? The post is cut down from the illustration.

I can’t hear or see any squeaks on that sample …


If the problem is whistling esses you’ll need a high-resolution de-esser plugin like Paul-L’s.

I don’t either. There is a very slight and very short high frequency noise between the words “Mary” and “was”, but nothing that I would describe as a “squeak”, and nothing loud enough that I would be concerned about.

Then the problem would have to be in the monitoring equipment?

A true story: An ex-colleague of mine had a problem like this - he was listening intensely, and each time the recording got to a particular point, he would lean forward and say “… THERE!”, at which point there was a squeak. After considerable giggling, the producer allowed me to fetch a new chair for my colleague - one that didn’t squeak.

the problem would have to be in the monitoring equipment?

I’m not sure where to go with this. Start with my suggestion up the thread of listening to the work on Something Else divorced from your studio.

You can have damage to the blue waves that is both visible and audible and the damage always appears in the same place every time. You can have “magic” damage where it wanders throughout the performance and changes at random.

You apparently have damage fixed in the performance and invisible, and only audible by some listeners.

I asked about a million questions up the thread. It’s probably a good idea to post some of the answers. We have to build your system in our imaginations and the more detail and model numbers, the better.

I keep the gain down as low as possible because my apartment building is pretty loud so want to minimise background noise.

Several people have said they don’t hear it I think I notice it more because I have noise cancelling headphones. Just out of interest what may be causing that very short high frequency noise in your opinion?

It could be anything. It is extremely quiet, virtually inaudible, but it is visible in the spectrogram. My guess is that it’s a mouth noise.

Reducing the pre-amp gain will not help to reduce background noise, in fact it is more likely to make it worse.
It doesn’t help, because you will need to amplify the track to get the voice up to a reasonable level, and amplifying will boost the noise as well as the voice.
It may make it worse, because recording at low level reduces the available dynamic range. At 16 bit, you have about 90 dB before you hit the digital noise. At -24 dB peak, you have 13-bits available, which puts your digital noise floor at around -70 dB. For high quality voice recording, you should be aiming for a noise floor better than -60 dB, but if you are starting off with -70 dB noise before factoring in room tone, microphone self noise, pre-amp noise … then you will be struggling.

In that case, the noise I mentioned in my previous post may be a noise from your apartment.

I’ve had this problem too in home recording. That just comes with the territory. I probably got the squeak from the chair or slight equipment movements on the table.

There are ways of dealing with a noisy room. This is a kitchen table sound studio.

In case the noise is coming up through the floor, you can try book/towel isolation.

An actual book is recommended. If you don’t have any of those any more, the local library frequently has $2 book sales and my neighborhood has “Free Book” pixie houses along the street.

These microphones are usually at their worst behavior with the volume all the way down. Try a test with the volume at least at 3/4 up. If you’re using noise reduction, you should be able to use less of it.

Yeti microphones are in the sweet spot of being expensive enough to deliver reasonable voice quality, but too cheap to have USB processing and filtering. This can give you the “Yeti Curse” where USB noises make it into the sound.

So this could be coming from the computer and is a USB error. Can you change the USB connection—does your computer have more than one?

Koz

If the squeak is coming from the equipment, would it not be constant? According to the thread title, this is a random noise.

There is nothing about this problem that’s normal.

The Yeti microphone is famous for passing USB 5 volt quality problems on to the sound.

By the way, there is a Yeti-Pro model which is much more expensive and doesn’t have Yeti Curse as near as we can tell.

Koz

Yes it shows up at random intervals, maybe every 15-30 seconds or so, but it seems pretty random within that range.

I thought it might be that so I wiggled around on the chair and it didn’t show up. I’m not sure what it is.
