Samson usb meteor mic whitenoise

Hi All just looking for some advice.

So I purchased a Samson meteor mic, mostly for calls and group conferences etc.

But I have found there is a constant Hiss / White noise.

so i fired up audacity with input volume at 50% :

and 75%

I was going to do one at 100% but it started hailing as you will hear.

I assume its an amp issue but being USB mic my software does not manage the device. I adjusted levels, there is no boost. many forums suggested its an EMF issue but i cycled computers and usb ports. I even isolated the mic in a room without electronics.

any advice would be appreciated.

All microphones have preamplifier noise. Microphone signals, the signal actually generated by your voice are really small and it’s difficult to boost them with nothing else going wrong. The object is to make the voice really loud and the noise really small.

USB microphones also suffer from “convenience” problems. Everything is built into one unit which is convenient until you need to change one of the things.

Instead of straight hiss, do you have Frying Mosquitoes? A whining sound in addition to the noise?

Attach a brief WAV clip to your post.

Yeah this is what i figure the issue most likely is, either the pre-amp or the analog to digital conversion.

There are two .wav files but i added another as per your request.

Thanks

Right then. Sorry. Wasn’t paying attention.

That’s an interaction between the processes in the computer and the microphone through the USB system. You may find as I did, that if you stick with a recording long enough and make the computer do other things, that you can hear the hard drive spin up and down.

There’s no known cure. We’ve been through all the variations: make the USB cable shorter, make it longer, put a powered hub in, take one out, etc. There is no one single thing that always helps.

It is down in the -45dB range which is pretty good for a cheap microphone, but it has the singular problem of sounding at the same pitch as children screaming on a jet.

So. One more posting. Record something, your voice, at normal volume. This is what it should more or less look like.

Devote one second at the beginning to nothing but the whining noise. Total silence. Then speak.

Hi, I was wondering if you ever solved your problem? I just purchased the same mic, and have the exact same issue. I have a friend who recommended this mic to me over blue yeti, and I have heard his stuff, I don’t know why mine is being awful. If you found a work around, please post, thanks. :slight_smile:

I have had background noise on my Mac with every single microphone that I have used – USB, 1/8" jack, you name it.

I use a software solution to do live denoise of the signal. If you are on Windows, the specific tech will be different but the principles are the same.


Here is the general “algorithm”.

Overview: We are trying to take your microphone signal, and put a filter that takes noise out of the signal (in software), and afterwards sends it to the program you want.

  1. Tell your OS that a fake Microphone / Output device exists

on OSX, I installed Soundflower: https://rogueamoeba.com/freebies/soundflower/

This creates a new device that you can tell your entire OS, or just certain software (hint: its the second one I use) to use as input.

For windows I don’t know but you might have luck starting a search here: http://alternativeto.net/software/soundflower/

  1. Install some software that will take mic input, denoise it, and send it to your fake output device

on OSX, I bought Audio Hijack for $49. You can and shold try the free trial. It worked for me so I bought it.

3) Tell Skype, Game (whatever) to “listen” to the fake device INSTEAD OF your mic directly
