Question / Help Having popping or crackling sounds while recording mic

I have been using obs and obs studio for quite some time and never had my blue snowball microphone pop and crackle in my obs studio recordings. I am using Voice Meter Banana to integrate some applications into my obs recordings. From what I can tell Voice Meter Banana is not affecting the microphone (I recorded the output of voice meter banana and re-listened to it, no popping). I went as far recording on my old laptop with OBS (not studio) and getting clear audio out of the recording. So I can deduce that the cable from my microphone to my computer works fine. I also transferred a recording from my main machine with the audio pops and played it on my laptop and still heard popping so I assume my audio drivers are fine. Whenever I use the my Voice Meter Aux Output (mic, spotify, and discord voice channel inputs) for my mic 1 in obs I get pops. This is the same output that I recorded through voice meter banana and found no popping in. I have my microphone on push to talk as well. My OBS Studio which the problem is occurring on is up to date: 19.0.2 The log file is below, it was taking a while to upload. Is there any way to resolve this issue? Am I missing anything?

Unfortunately, this is a common issue with Snowballs, I owned three in total and they all inherited it eventually, as did my friend's also. :(

Here are the results. Are the blue microphone and the gaming mouse in the same root? I don't understand roots fully. I do have an elgato but it is not plugged in as it is rarely needed. The only other variable that is new before this occurred is a software called audio router though OBS Studio worked fine with it.

What you describe could be "distortion" from audio levels. Analog distortion can be more of a "fuzz" sound. Digital distortion via USB mic could in some cases be described as "crackles and pops".

I would experiment with lower signal gain coming in. Trim the input gain in half to start to see if you have the same issue.

The second image you posted shows that you moved the Mic onto it's own Root Hub, which is a good.

As to the popping still happening, make sure that the mic+voicemeeter+OBS are all set to the same sample rate, and if you can increase the buffering in Voicemeeter, try doing that.

Lastly, if you add the mic directly to OBS does the mic still pop?

Interesting find, could this be the issue? The amount of channels is different. Otherwise the audio sample rate in obs is the same. Does the channel being set to stereo in obs have any effect either? Voice Meter Banana also says that the output is 44100hz/4096hz. The Mic/Back OBS Column is what I am plugging into OBS as Mic: Voicemeter AUX output.

Additionally, I did take the mic out of the virtual aux audio cable and send it to OBS and still received popping. I haven't changed the properties shown in the pictures below. I am curious if the 2 channel vs 1 channel could be making popping sound. My elagto is at 48000 Hz with 2 channel and 16 bit

thought it is not inserted into voice meter banana or obs.

I couldn't hear the example (video was gone) but if it is a popping sound while using PTT then I fixed a very similar issue by going into Settings > Audio and then changing the Push To Talk delay on my mic to 50 ms. No idea why that worked (it actually makes no sense that it would) but now I get no crackling at all when using PTT in OBS.

I do remember a conversation that the live techs had in the chat room about there being some bad Blue mics out there that no matter what you do have popping/noise in the mic. Getting the mic changed out for a new one would sometimes fix the issue, and some would change it for a different mic altogether.

ParGellen's delay worked. The lowest I could get it to be without popping is 30ms. When putting in 30ms OBS Studio wants to set it back to zero but if i save it and come back the delay is 30ms. I am curious what causes this popping though since my mic is closed until I open the mic. Thanks for the help everyone.

I found it to be linked to switching scenes... maybe this will help other people:

Question / Help - Audio Cracks/Pops when I switch Scene

I just started having an issue where I hear a crack/pop in my mixer every time I switch Scenes. Here is a video I made explaining and showing the problem. https://youtu.be/OHfvyKLup5c Current Log FIle: https://gist.github.com/bddbe23a9ccc411ab373a492ca3a5c71 Last Log File...
