Hello,

When recording with my mic i have a electrical noise in my audio. I'm not sure where it is coming from and how to fix it. I have tried many ways to fix it. I use a Blue Yeti USB microphone and have my USB plugged into the back of my PC in a 2.0 port. I have tried moving my other USBs around and isolating my mic USB. I have made sure there wasn't any interferences like cell phones and things. I've tried different audio levels which helps but it only makes the noise quieter and i have to talk really close to my mic. I'm very sure its not a hardware issue but could be. I have always had this similar audio issue with 3 different PCs and 4 different mics. I'm not sure if its a grounding problem with my outlet or not. I have moved my PC around to different outlets and i have a huge APC surge protector. I would love to get some help on diagnosing what this noise is coming from. I'm am able to post a video of the sound if needed and whatever else would help.

Thanks, Chachi

I've been looking into something similar - my setup is different to yours by a long shot, but from what I can work out it's related to a ground loop. I haven't found a viable solution as of yet, though the closest thing to one I've found relates to using cables that don't carry any additional voltage.

This might possibly help you depending on your setup: http://forum.cockos.com/showthread.php?t=113721

The original OBS has had these sort of issues in the past. Could you give me a log file?

Hi Jim,

Thanks for the reply. I'm not sure how to post a log or where to find it. I can also provide a video of what it sounds like if that would help.

Thanks, Chachi

What series motherboard do you have?

For instance, I know the Q/H/Z67 series motherboards have faulty grounding on their audio ports... which adds a "hum" to the inputs and outputs. This issue was later fixed in the Q/H/Z77 series and beyond.

I fixed it on my old PC which had a Q67 by using one of these:

Thank you for the log. I don't particularly see anything wrong with the log. I might have to ask for a video or vod.

Original meaning the regular windows version that everyone uses, apologies for the confusion. We have a new version which will eventually replace it that fixes a number of issues with the audio subsystem among other really nice improvements. It won't be released very soon though.

By the way, completely unrelated: I hope you're not using monitor capture to capture any game. It's very inefficient on windows 7.

Hey all, as far as the Blue Yeti electrical noise, it's a somewhat common problem with the blue yeti and non-grounded PC's. My suggestion is to try and pick up a cheap 4 port powered usb hub and plug the Yeti into it then plug the hub into the pc. I've had a few friend run into this issue and the powered hub has solved the issue for them so you might want to give it a try.

Hello,

I can't seem to attach the file. I have a video and had to compress it to a .rar file. When i choose the file nothing happens and i don't see any button to click to upload.

Thanks, Chachi

You might have to upload it somewhere else (youtube or anything like that) we can view.

It sounds like background noise on the microphone, but I will fully admit there's something wrong with the audio processing somewhere in the current version of the program that's causing this weird issue to occur. You may have to bear with it until we replace it with the new windows version of the rewrite, where we've confirmed audio is working properly.

A solution for me was this:

The sounds you are hearing are actually voltage differences throughout your pc - caused primarily by the powerstates of your processor.

Disabling C1 and S power states in my bios completely eliminated the electrical tweeting noises.
Also, purchasing clip-on ferite chokes and applying them to the USB cable at both ends reduced a high frequency hiss at higher gain levels.

Tweaking the sound is a good option too, if you have your PC-Gain set up (Mic recording > 50%) it exacerbates the issue.
Your aim is to have as hot a signal coming from the Mic, without further amplification from your pc.

I have the Yeti input on the pc set to ~25%
the gain on the yeti itself set to the 1o'clock position
the mic positioned ~18 inches from my mouth
in OBS, i have mic boost multi set to 2, and noise gate set at resting volume.

Source: Me, I use a yeti too.
