removing background noise

Post by TripleGemini » Fri Mar 20, 2015 4:24 pm

I have windows 7 and I have version 2.0.6 of Audacity. I have trying to figure this out, but then realized it might not be possible, but I wanted to ask to double check.

I do live-streaming on Twitch and I was wondering if there's a way to use Audacity to get rid of background noise on a live stream rather than a recording? I use the recording part a lot when I upload videos to youtube, but I wanted to use it to help get rid of some or all of the background noise when I go live on twitch?

Audacity is a post-production program. It does almost nothing in real time. Sorry.

What is your background noise? We recommend almost without question to get rid of it in your studio rather than trying to do it with a program. The audiobook producers recommend that, too.

Post a WAV test of your studio. Start a recording, hold your breath and freeze for two seconds and then speak in a normal recording tone of voice. Stop at ten seconds. You can post ten seconds of mono voice on the forum.

Here is the ten seconds. This is what happens on every recording, and this is what I'm trying to get rid of. I do use noise removal when I need to record my voice for a youtube video because people won't want to sit through 5+ minutes of that noise. I also have two microphones, one being a blue snowball, and then the other one is a headset with a attached mic, and that is what I used for the test audio... teh headset is the Gamdias Eros Vs 2 gaming. I normally use the blue snowball, but I have wanted to try out the headset mic more since I have to use the headset anyway to listen to audio now that my old headphones don't work like they used to.

And I thought about using the headphone mic for twitch since it's easier to use the keyboard, where I need to have the blue snowball directly in front of me to use properly.

Thank you. That's perfect. Now I need to read through that again and match model numbers. That's not normal microphone noise. Normal production microphone noise is higher pitched and more piercing. Also, this stuff goes way down into the bass notes where I need the tools to even tell that it's there. That kind of noise can mess up some of the other filters and effects.

As we go.

So. It's an analog headset with one of the connection options being an 1/8" plug with three black or dark bands, right? Or does it connect with two separate plugs like this?

It actually connects through a usb, and the blue snowball is also usb.

I knew about the Snowball because I used one once or twice. I think Ian in Hollywood is using one to produce his audiobooks.

I do have a Logitech USB headset. I stopped recommending headsets for theatrical recording. It's noisy, has hum, and features crisp airplane pilot vocal tones. In other words, a close cousin to what yours is doing. I think this is what happens when somebody says the words "Gaming Headset." It has to punch over the gameplay and other sounds in the show and that's how they did it. Nobody is awarded any Orc Points if the performance is quiet, so they're all noisy.

There is another way to get around this. They certainly make full theatrical headset microphones that rock performers use. They can work very well, but they tend to have other restrictions. Most of them come ready to plug into a radio microphone system not a simple cable or Microphone Preamplifier. That will be several thousand dollars, sign here.

Oh, and they do take separate headphones (earpieces in the case of the performers).

I don't see an easy way out with what you have. It's not unusual for patches and additional equipment for your existing microphone to pretty much equal the cost of a better microphone. This is exactly what happens if you need to plug your gaming headset or computer microphone into a larger, professional sound mixer. You end up building the adapter box yourself because it doubles the cost of the headset. (I have a picture of mine here, somewhere...)
