Kill the Mic Noise – Hiss, Hum and Buzzing

Kill the Mic Noise – Hiss, Hum and Buzzing


away from the start I could feel it in my
heart. all the way from start. hey what’s going on out there I’m Sean Divine hope
you all are doing well today I want to talk about how to get rid of unwanted
noise from your vocal recordings many of you out here have a lot of concerns
about some more noticeable noise that happens in your vocals and then there’s
some that’s just very subtle that becomes more of an issue once we start
processing the vocal doing mixing and compression EQ all that type of stuff
will ultimately make the noise more noticeable and it’s just really not a
great look if you want to have the most professional vocal as possible so we’re
gonna talk about first some preventive measures to take so that you can prevent
the noise before you start recording and that’s going to make things a lot easier
once you get into the DAW and start processing your vocal we’re also going
to talk about some ways that you can at least help the noise if you’ve already
recorded it you have it and you need to treat that a little bit let’s talk about
the first three ways that you are gonna introduce noise into your vocal before
you start recording so the first way is just room noise now for me my primary
issue with room noise is I have some very bright lights there’s one in the
back of the room that produces a buzzing sound so generally if I’m recording
something that’s not a tutorial where I don’t need the light then that is off so
what you need to do is you need to walk around your room and become more aware
of these things that are producing this unwanted noise you may have heating
boards base boards that are buzzing you may have a refrigerator upstairs or
something that is causing a little bit of a rumbling sound you may have an AC
unit it could be a number of different things that are causing the noise so you
want to turn your mic on put on a set of headphones turn the gain up so that you
have a really healthy signal going to the mic and just walk around and just
see where you can pick up on these types of things
try to eliminate it if you can’t eliminate the noise try
to minimize it and keep your mic as far away from that as possible so if you
need to set up your mic across the room away from the AC you want to do that so
the second way that you can introduce noise into your vocal recording is
either through the mic itself or through your preamp or audio interface so
certain mics are quieter than others for example I’m using this sm7b which I
generally use for my tutorials and my just spoken content and it’s actually
one of the louder mics that I have it requires a lot of gain so I have
something called a cloudlifter that provides 20 about 20 dB of clean gain
so that I’m not having to push the preamp as much so the preamps themselves
actually have a little bit of noise and the higher you have to put up that
preamp some preamps will have a more noticeable noise than others so be aware
of the noise level of your mic the best way to experiment with this is to try a
couple different mics for instance again the sm7b is the loudest mic I own the
quietest mic I own is the NT1 by Rode it has very little to no self noise I
can’t notice anything even with the preamp jacked all the way up it’s very
very quiet so you can just experiment and find out if it’s the preamp that’s
producing the noise and or if it’s just one of your mics is louder than the
other but you want to get the cleanest preamp gain possible so do a little
research on your preamps and your audio interfaces and make sure that you’re
producing clean gain and not a very high noise to signal ratio alright so the
third way that you may introduce noise into your vocal signal is just through
some type of electrical issue now there’s a number of different things
that can cause electrical issues around your studio but the first would be you
may just have some kind of component in your chain that
hooked up in the same outlet that is introducing some type of interference
for instance the monitors my main monitors they’re not electronically
shielded as well as some of the other components in my studio and so they
produce a little bit of a hum and I have to make sure to turn those off or I
can actually hear that being introduced in my preamp so those have got to be
off things like that you want to notice and that’s really a matter of trial and
error of unhooking everything hooking up each thing individually I have a
keyboard that produces a little bit of a buzz and I have these little things that
I’m gonna show you in just a second it’s called a hum X and you can actually hook
your three prong plug from your component into the hum X then plug that
into the wall and that will help with ground loop my computer is actually
hooked up to one of these hum X I was having a very strange ground loop sound
it almost sounded kind of like a cell phone interference with a lot of low-end
rumble that was happening and I had to hook up my iMac my computer into a hum X
to get rid of that so you may actually have some of that coming from the
computer itself so you want to check all the components one by one and see what
could be causing a ground loop so an absolute last resort is that you may
have electrical issues in your studio or your house in terms of the wiring itself
now that is not as easy as a fix it’s actually really expensive you may have
to hire an electrician to come and ensure that your home or your studio is
properly grounded I have not seen many cases where this has been the cause of
the issue but I have heard about it it does happen but most of the time these
things we’re talking about if you just treat everything and look at it very
very closely individually you can narrow down the problem and you’re gonna find a
solution in these steps we’ve gone over all right so we’ve talked about how to
prevent some of that noise in your vocal recording but let’s just say it’s too
late you already have a noisy signal in one of your sessions and you want to try
to treat it after the fact it’s a little bit more difficult to do but there are
some options I want to about my favorite ways to treat noise
and make it less noticeable so let’s go ahead and jump into Logic Pro I’m gonna
show you a couple of ways that we can try to tame that after the fact all
right so I’ve got a session here with a somewhat noisy vocal I want to show you
here in just a second but the first thing I want to point out is that I
actually have this control on my interface where we can do a little bit
of processing on the signal going in so a lot of you have probably noticed that
when I’m quiet it’s silent so I’m using a noise gate on
the dynamic section here going into my interface now if I turn the noise gate
off that is the noise of my hard drives my computer and a little bit of white
noise that is produced by the actual microphone so then if I get that out
this can be really useful for you when you’re recording your vocal it just
makes it less noticeable when that noise is not present whenever I’m not speaking
or singing or rapping or whatever it is I’m doing now I would recommend that if
you’re not just doing something like this where I’m recording a screen
capture if you’re recording you know a vocal that you’re going to be mixing
later I would do the noise the noise gate after the fact so you would just
leave that off and then once we get into the DAW itself then we can do the same
thing but you don’t want to get hasty with this noise gate going in because
sometimes if you don’t set the threshold right there might be you know a little
bit of a rasp at the end of a phrase or something or just a little subtlety in a
performance that’s a little softer than the rest that may get cut out with a
noise gate that’s going in on your recording chain so just leave that
flexible for the mixing process in the DAW now let me show you just a vocal
that was recorded just like this right next to my computer a lot of hard drive
noise and let me just follow that for you I’ve been trying to find myself in
all the wrong places calling out for love to all the wrong faces ah yeah what
you see ain’t what you get sometimes back in ’09 left me feeling like I’m
dying never again you’re left counting down
the hours got to find that love counting down the hours got so you can
hear the noise in the vocal and what I like to do is use this tool called NS 1
from waves and let me just play this back this is without it again never give
someone that much power that when it goes sour you’re left counting down the
hours got find that love deep down in yourself is
so you define your purpose it ain’t up to no one else
and I’m so now when I turn that on and never give someone that much power that
when it goes sour you’re left counting down the hours gotta find that love deep
down in yourself its on you to find your purpose it ain’t up to no one else and
I’m breathing a deep sigh that I made it out your clutches I’m wishing you the
best but you can’t tell me nothin not just so it actually takes out a little
bit of the room noise as well as some of the hard drive noise and hiss on top so
a very useful tool and there’s a lot of other types of noise suppressors out
there this is just the one that I tend to use the most there’s some incredible
technologies that can take this stuff out of recordings but generally you know
something really simple like this and a noise gate is all I need and the key
here being that if you do all the preventative things we talked about you
don’t have to do as much work and post of course you know there’s gonna be
situations where that’s just not possible you’re in less than ideal
environments and you can’t treat the noise until after but if you can it’s
gonna make your job a lot easier so that you don’t have to be in here doing a lot
of science experiments to get rid of the noise from your signal alright y’all so
that’s a couple of ways that you can both prevent and treat noise in your
vocal recordings the key here is you need to experiment I’ve spent sometimes
hours and hours over a couple of days trying to narrow down the source of a
ground loop or a white noise that was being introduced in my signal somewhere
and sometimes it can really be difficult to find but you have to just unplug
things and try different mics figure out the way your preamp is behaving if it’s
producing noise different components together are gonna produce some noise
your room may have some noise there’s a plane flying overhead right now that you
can probably hear so all these things you just have to be aware of them and
hopefully this helps y’all if you have any questions or comments about noise
and your vocal recordings leave them below if you learned anything in the video

  1. sound clearly nice but not cuz ns1 we all know this was a tipp but not also mega helpful facts yeah definitely but pls explain all plugins or just show how ur set up is bro…

  2. lol i was just like wtf when i saw you only have 30k subs i literally thought with quality content like yours you are already above the 100k

    keep it going man love all your content

  3. Hey Sean. I know you're busy so i'll make it quick. I think a video on phase cancellation/polarity/phase inversion would be incredibly helpful. I have a song with a lot of different synths bouncing around and i don't know if they are fighting over each other. Thanks man

  4. Great video another way you can stop some of the reverb from an untreated room is to use a transient master plugin and reduce some of the sustain.

  5. Sean, I own the NT1 and notice a little white noise or my external HD fans as well. I use Screen Flow to record my videos. Do you record your vocals using Logic or do you use the program that is capturing your video also record your vocals? I am unable to place a gate during my recording if you could provide a solution that would be great.

  6. I use rode video mic and the hissing noise is annoying its too loud on cubase my recording is shitty for now…

  7. I use rode video mic and the hissing noise is annoying its too loud on cubase my recording is shitty for now…

  8. I bought Audio Technica atr2500 n wen i recorded smthing there is some hiss sounds, too wen i closed all those windows n doors it is still there…Can anyone help me plzz

  9. Why do I get so much white noise from software instrument recordings? Also, when I listen back, I can hear a lot of white noise from my headphones???

  10. So I recently purchased a pair of AKG K7XX's as well as a massdrop minimic to replace the pair of Logitech G430's that I have. The Logitech headphones weren't the best but there was never any buzzing when plugged into my PS4. Today I connected both my K7XX's and my minimic to the audio/mic to usb joiner that came with my Logitech headphones, and there is a very noticeable buzzing sound. I know it is not the mic because I've plugged them into my phone and tested them, no buzzing. From what I've read online it's a grounding problem with the PS4( the sound is electricity). Since it is only 2 prongs it's not grounded. So my question is: In order to ground my PS4 do I need to buy a 2 prong to 3 prong adapter, Or is there something more that I will need to do? Also, have any of you had this problem and if so what did you do about it? Thank you

  11. Crazy.. As you said "there's probably a plane flying over head right now that hit can hear.." a plane flew over my apt.

  12. Bought a new 2018 Mackie Thump 12A 1300 watt for a personal vocal monitor to hear my self more clearly and most of all more loudly.
    Already running 1200 watt peavey amp into 2 peavy passive 15 inch speakers. Its level has been loud enough for years but i knew I needed to hear myself better to perform better and avoid vocal fatigue. Its not loud enough and disappears as soon as we start playing. Tried different cables, dynamic and live condenser mics etc. Mic gain and mon both up at 90% then starts feeding back at 100. Sounds ok when no one else is playing. Plays music from phone or ipad much louder than singing. Were not crazy loud either. Loud but not intrusively or out of the ordinary for a rock band. This thing would be great for kareoke or an acoustic quieter band but not for rock music. Talked to several techs who were all confused from different companies. Finally received a replacement and its exactly the same. 1300 watts should be blowing my hair back. Is one powered wedge usually good enough or do you absolutely need 2? Never had many problems on stage hearing myself on 1 of the houses though they were not self powered. We have an old powered old JBL 500 watt or or something that's around 30% louder and lower watts.
    Anyone else experience this with Mackie or any other mfgs? Is this normal? Thanks!

  13. when i make microphone recording volume as 100, then the Hissing, Buzzing is be running on background. Please tell me how can i remove it?

  14. I live next to 4 lane road in nyc on 2nd floor, 50 cars pass by in 4 minutes… including 5 buses, 1 cop, and 10 trucks..

  15. Ok, so,,,I am a Voiceover and recently got a Rode NT1-A. The quality is great. It is billed as a quiet mic, but when i do recordings I still have faint hissing noise in the background. I think it might be something to do with my gain and mic volume settings. So, do you or anyone else here have suggestion about what the ideal volume and gain setting combo might be? Thanks

  16. Thanks so much for this omfg for some reason the lights in my room were making some mad buzz on my mic and as soon as I turned it off BAM ITS GONE YEESSS THANK YOU 😂😂❤

  17. Hi Sean, I came upon your video because I’m desperately trying to fix bad audio on my video that I want to upload to YouTube. I’m really upset about how it sounds but I can’t refilm the footage and would really like to salvage what I have. Basically either the mic I purchased is really bad or I’m using it wrong but it’s picking up every little sound and since it’s a clip-on body mic my voice sounds totally off because it’s too loud? Not sure how else to explain it, but I’ve been researching for hours and trying different methods on Final Cut Pro but nothing has really fixed the problem just made it a little less noticeable. If you could respond to me here or are willing to help me via email I would be extremely appreciative! My email is [email protected] Hope to hear from you, thanks!

  18. It is not "Rood" but "Røde". It sounds like this: https://translate.google.com/#auto/da/r%C3%B8de

    I'm from Denmark, so I know, how it is pronounced.
    (Click the speaker.)

  19. Looking for tips on treating cheaper mics . . . I regularly do live sound for a public speaker and then mix onto a website. Our mics have noisy housings. Looking for tips to deaden the actual capsule or how to treat capsule plosives.

  20. Hello Sean, great vlog, I needed those explanations! I am French, making movies, short-movies & docus. I have indeed those humming issues with my h4n zoom recorder & NTG2 (dual powered directional condenser mic) rode microphone, and they are bothering me quite a bit now, especially for some of my voice-over work. I'm still trying to find out where the issue could come from. I am editing in Power Director 14. I would like to know if it would be useful for me to purchase the Audio Director program that can work with the editing program and if I will be able to correct those humming issues. Thanks in advance!

  21. I didn't find the part, where you explain how to actively go against the noises…? Could you point in the right direction? E.g. What do I do, if I have a loud mic?

  22. Hi Sean. I have a BabyFace Rme interface. It is supposed to be a very good interface, but when I record with my KEL microphone condenser, if I use the volume in my BFace preamp. I get this terrible HUM,, HISS or whatever it can be called. Will the cloudlifter help me record using a lower volume with my preamps, even though it is a condenser mic.?? I get this sound from the preamps, even when I don't have my mic connected, if I boost the volume to high. Please let me know, before I kill myself ( IT is a joke). I am tired of this stupid noise. Will using a USB noise filter, help with this noises???? https://www.amazon.ca/iFi-Audio-iSilencer-3-0-Filter/dp/B01MXDZ0PO I am desperate, and it takes away all my desire to do music.

  23. Hello Sean, a loyal fan of yours, great Job keeping the tutorials coming, quick question though, why do u use the SM7B if it's louder than a quieter mic that u own, "Rode NT1", why don't you use the quieter one without the noise for your tutorials then? and do cables introduce noise as well?

  24. Hey I use a BM 800 microphone and I tried using it in audacity and the I heard it and there was just a buzzing noise. I also checked the inbuilt mic of my pc but the buzzing sound wasn’t there. Please help me with this and please tell me if this is the problem with my mic. I also use a soundcard. Please help me with this.

  25. Hi we do have audio noise issues, in our church live streaming.
    We use vmix and signal comes from Yamaha analog mixer into our PC through couple of RCA Jack's.

    Could you please guide is in resolving this..Using Noise gate reduced noise in vocals..but when more instruments comes signal will be more noisy..

  26. Hi I have rode nt1a microphone and people say like yourself it’s the quietest microphone but I still pick up buzzing sound I think it’s from my computer’s system unit, it’s bothering me, do you think I should complain about this at store?

  27. A few years back my dad installed a full on new outlet next to my bed. Can this be a cause of noise? It's poorly isolated.

  28. So even when I unplug my mic from my XLR cable there's still a buzzing sound in my headphones, would that be faulty wiring? I have a mac book which has a little converter for USB type c which connects to my audio interface then my mic.

  29. Hello bro, Actually I have a behringer uphoria um2 as well as bm 800 mic. When i recordes a song so strange noise is coming. What to do bro?

  30. Walk around the room… and ELIMINATE 🤣 this is a very useful video. Most people I collab with or produce have a lot of these issues. I'm going to save this and use it as helpful reference for the future. Thanks man 🙏

  31. Hey I hope you got a chance to read this but I’ve mixed my songs and master and I can here like an empty space like white noise line from the begining of the song

    And then it stops once the first verses play and at the end of the song it happens again what is the cause of that?

  32. turned out it was the ceiling fan, even though I had it switched off at the fan the power current was still causing a hum. Had to turn it off from the wall switch.

    Thanks for the help from this video!

  33. Even though my mac wasn't even plugged into it, it was my POWER STRIP nearby (which was switched On) that was causing some weird interference with the mic. Never would have thought that that could have been a culprit. Thanks for helping me think critically and do some investigating!

  34. Great video! I just shoot one restoring my 1955 RCA BK5B ribbon mic that I found in a box from my uncle!! Check it out! ​@​

  35. A Huge thank you, my interface was making really loud noise and just using my pre amp sorted it out. Peace!

  36. Is it ideal to add a noise gate to every vocal track, or just the ones that are worse than others?

  37. So please hear no disrespect in this, but I'm trying to learn about eliminating noise. I hear a lot of preamp hiss in this video in between your gate and when you speak. I have the same issue, but this is even more problematic because I'm trying to record DI electric guitar through an amp sim. Obviously this is magnifying any noise by an exponential amount. I'm curious if there is anything that can be done to minimize the noise of an electric guitar straight into an audio interface. Additionally, I'm hearing little to no noise when I'm monitoring just the recorded DI guitar, but when using an amp sim, it becomes apparent with any amount of grit or distortion.

  38. It's a misnomer to say that the SM7 is a "loud" microphone. Because of its low output volume (and noise issues are amplified), the SM7 in this context is a "quiet" microphone.

  39. Thanks so much !
    My problem with noise is the hiss like radio from my distortion rack just in one channel… Sometimes come other times ithe sound is perfect but this week i heard a really hard noise from the head power amplifirer 😕 im comfuse cuz i need to wait a long time for play.

  40. i have the nt1 but it sill has the white noise im not sure what to do. if i get a better audio interface would it help? i have a cheap one rn

  41. excuse me I accidentally record vocal at the master mixer how to eliminate it????….. sorry my english is poor…..

  42. My buzz is when it's mute and when it's on it's a solid buzz think it's my front panel connector wires because I had too run them under my GPU which is really close too the fan so I'm thinking that's it

  43. I had humming issue on my mixer. Problem was that the AC cable was not all the way in. This video made me more aware, thanks.

  44. I keep having this problem with my beats, i always hear a very grainy sound in the background of people talking, do you know how to fix this?

  45. This was extremely helpful! I've finally found the solution to the problem that I've spent MONTHS trying to solve! Thank you, good sir!

  46. I have a guitar with humbuckers going into an interface into a laptop. I'm pretty sure its not the guitar cause i took it to the repair guy and he did a complete setup. When i touch the computer or the cable Jack it goes away completely. Could it be the interface? I would just record with a little buzz but it's super freaking loud! I'm also using th3 amp simulator. I tried downloading amplitube and it does it on that too. Help me!

  47. Then how to record without fan, AC ?
    Don't u sweat without these ?

    I m having problem to record without fan and ac…bcoz it's summer in here…
    So if I switch on fan….
    It creates noise..
    And I m not having any solution of this ..

    Pls Suggest.

  48. My mic makes a humming noise if I plug it dorectly into my computer. But if I plug my phone in, and then plug the mic into the phone, it works fine. Is there some other hardware that would do what my phone is doing so I didn’t have to use my phone?

  49. bro you the man it was my rocket monitors humming like that my damn man thanks bro keep dropping those jewels bro I've been filling you since 16 and you have really helped me out homage my g!

  50. will the cloudlifter turn a dynamic mic level signal into line level signal? and how would that work with a mic that needs phantom power?
