I just bought a Samson CO3U USB mic, and although the sound quality is great, there is ALOT of background noise. I'm in a completely quiet room, but there always seem to be this slight buzz sound going on. If I go to mic options and click on "listen to device", I will have nothing going on in the room, and I still hear this very prominent background noise. When I go to a recording program like cool edit pro, as soon as I press record, I see something's registering the entire time when the room is quiet. Is this a problem with the mic itself? I'm asking because I've heard many recordings done using this mic and reviews on youtube with the sound is completely clear. How can I get rid of this? Thanks.

Thank you P10, Jack... my thoughts exactly...

K-Ro, never mind... but it is better to ask and corner those old chaps like myself to tell you how it can be done better with the same gadgets
then claiming to be the marvel recording man of the, now, Phantastic 5.. ;-)

I dare to say that the gray heads in this forum have seen it all and been everywhere in this job. From Grammy prize winners to the unsung heroes...
1 day with them could teach you more then a semester at the SAE, e.g. Just ask and they give you valuable answers to your problems.

Pop filter. There are two basic kinds. One is a metal screen and one is more of a fabric like pantyhose. Sometimes you use one of each (or two of the metal version) on really "spitty" voices. Some manufacturers make them with integral attachments to the mic but most clamp on the mic stand in some fashion. A 100% necessity for voice over work.

A wind screen-which is like a condom for microphones-is not the exact same thing as a pop filter and tends to attenuate some frequencies that a pop filter does not. Better to use one of the above just like pictured.

but belive me i make everything to good to be true even if i record in a noisy environment with a freaking USB mic i still can make it better than u ever will do with ur thousends of doller studio

Hey K-Ro or should i say Quincy......
your right i (and we) have no idea how your tracks sound. I DARE YOU TO POST THEM, but you can hear some of my tracks on my website you little shit..........nothing in my post made any indication that you did not know what you were doing just a little bit of INEXPERIENCE.
i gave you practical advice to FIX YOUR ****ING PROBLEM before you record it. so guess what you little bitch, if this is the attitude that your going to have LEAVE THE FORUMS and let the REAL engineers that are trying to learn something LEARN instead of you hogging up their time with your snotty attitude. you dont deserve to be called an engineer. (whats up with these little ****ing amateur engineers that have to say they can do everything better than everyone else, is this whats become of the music industry???? no wonder we have more BAD music out there than GOOD)
so i say to you Quincy Jr., when you join the GRAMMYs as a voting member let me know.

Using a generic high pass filter on every or even [most] voice recording is just bad judgment. Better to learn how to mic the talent properly in a half way decent environment than accept sub standard results. What sounds good to a beginner now is not likely to sound good ten years from now to someone who has continued to grow and learn about this craft.

For me, I have no control over the environment other than my location in it. I specialize in event recording. Even when I get it wrong, my mics still hear better than I do. And most times I'm there as a favor to a friend and not a paying audience member, so being courteous to the audience is more important than proper mic placement and/or walking around like I own the place. I'll try to get a good seat, but priority always goes to the paying attendee. Perhaps a bit different if I venture into PAID situations. But I'm not there yet.

My mics have a high noise floor. My venues have a high noise floor. Windscreens can only do so much. Reflection filters can only do so much. Fortunately I record somewhat loud sources so a lot of that gets mitigated because of the source. But I find myself in other situations where the speaker is half a stadium away or I don't have space for the big and good stuff. So knocking off entire bands of frequencies to make a speaker easier to understand is an improvement. Applying a noise filter to the resultant wave can bring the hiss down considerably. Not without their woes, but options to consider.

In ten years perhaps mics and windscreens and reflection filters will be a thing of the past. Noise floors will be closer to 0dB than 30dB. Free software will have the ability to figure out the room physics based on the recorded track and improve the result considerably. Until then we're left with more dumb .gov mass punishment style edits. Like a highpass filter.

the one thing that nobody has addressed about removing background noise from a recording is to use an expander..........
this is the ONLY effective way, other than cutting out everything between the vocals in the track, to remove the hint of a noisy recording.
a pop filter only removes plosives, not room or mic noise, removing bass is truly not the way to go, FILTERING the voice with a highpass is what you should be doing when removing BASS.
so there you have it. put an expander in the mixdown chain of your track and watch what happens, NO NOISE

There's gold in them thar hills. An expander has been suggested in the past on other posts. The only thing is you have to be careful as they can cut the tails off of your notes as well. So setting the threshold is going to be a tricky balance. One thing I have a tendency to do is just plain edit the noise out where it's practical. With digital editing it's so easy and it'll save you the use of yet another plugin or rack device.
