Removing Florescent Light Noise "Hum" from Audio Tracks using FCEHD

I have some clips taken under florescent lighting where the hum was discernable even during the sound check. (I was using external Electro Voice hypercardiod XLR mikes plugged into my Sony DCRVX2100, powered through a surge protector, monitoring the audio with Bose QC2 headphones). Using the same camera, cables, and mikes under incandescent lighting that day was fine - no hum.
Attempting to filter out the hum using the FCE Hum filter wasn't dramatically effective, even with repeated tests establishing that using a frequency of 60 hz, a Q of 40, a gain of -48, and the 1st and 3rd harmonics provided the most benefit.
Additionally I tried again with the FCE 31 band EQ filter, anticipating that the 50 hz and 60 hz filters would provide very specific improvements. Also tried were the LowPass Filter and the 3 band EQ.
I'd like to clean up the otherwise fine audio - any suggestions? I am considering buying a filtered power conditioner as I know that some of the problem can be "dirty" electricity resulting from the ballast of the florescent lighting.
Also, I noted that the numeric values shown for the gain using the FCE 31 band EQ filter oftentimes lagged behind the setting of the slider: returning the slider to the middle "0" position frequently didn't change the previous value of the gain shown. Is this another indication that I should just upgrade from my PowerBook G4 with 2 Gig of RAM?
Thanks!

Hello Jim,
And welcome to the Final Cut Express forum.
You are correct that the ballast generates the hum. Power conditioning is probably not going to reduce or eliminate it, because the old ballasts are magnetic. The only way I found to eliminate fluorescent noise at the source is to replace the ballast with an electronic one or replace the entire fixture with a T8 unit (they use electronic ballasts).
Removing that hum probably can't be done in FCE. Sound Soap can probably do it however, with it's ability to +learn noise+ and then remove that specific audio. The regular Sound Soap works as a plugin for Final Cut, which enables you to apply it within FCE.
At present there is also an 'SE' version available at 50% off however it only works in standalone mode, which means you would have to export the audio track from FCE, clean it and then re-import back into FCE.

  • How to get rid of wind noise on the audio track

    I am sure there must be a method to get rid of wind noise on the audio track. Can someone tell me what the best filter is for this purpose as I shoot mostly outdoors and even with a sock covered mike I pick up the wind noise? I have FCS and therefore Soundtrack Pro. Are there filters in the audio filters section of FCP or must I go to STP? Thanks in advance!

    I shoot mostly outdoors too, and it gets pretty windy where I live!

    I hope you mean you have a Rycote "Softie" or something similar protecting your mic . . ?
    If so, you should be able to shoot in quite a high wind without any "wind noise" - but of course, even if your "sock" is correctly fitted and working well, you'll pick up the sound of the wind (different thing altogether).
    If you have the right gear and are experiencing the buffeting sound you get with an unprotected mic, then I suspect there are gaps somewhere - so tape them up!
    Either way, for removing unwanted sound, I know of no tool like the Linear Phase EQ filter in STP. Like everything new, it takes a little time to learn but it's very well worth it. With practice, you can almost slice out much unwanted sound like a knife.
    I'm not sure why you don't want to use STP - it opened up a whole new world to me - and it's easier to learn than FCP IMHO.

  • Can anybody out there help shed some light on why no audio output using varispeed tempo only

    Can anybody out there help shed some light on why no audio output using varispeed tempo only?
    I am using Logic Pro 9 and finding no problems using the tempo and pitch option but when I just want to vari the tempo only I loose all output.
    This includes no audio meter activity on channells.

    Another worthwhile time/pitch related product is from Prosoniq. The version of Nuendo (not the latest) the University uses ships with the MPEX algorithm, which is related to to their flagship product.

  • Removing hum from audio

    Lost the audio tracks from the mixer, so
    all I have is the audio from the RED camera.  There is a constant hum.
    I tried the DeHummer tool at different settings, no luck.
    All I have is Premiere CS5, no other tools like Audition.  Is there a way to remove the hum
    since it is constant?  The audio files are *.mov for some reason, so Audacity didn't help either.  Of all the scenes that could get screwed up, its the one with my five year old in it!  UGH!!!!!
    Thanks for your time,
    Stuart

    Stuart,
    Much will depend on the frequency range of the hum and on the frequency range of the Audio that you wish to preserve. This ARTICLE will give you some tips.
    While I use Audition, SoundBooth (do you have that program, as it's included in most Adobe suites?) should be able to help, as can the great, little free Audacity.
    Good luck,

  • ??? Make a CD recording from audio track

    I need to make a CD recording of an audio track that I have in FCP. Can anyone help?
    Thanks,
    Glenn

    You need to take the aiff file that FCP exports and drag & drop it on the iTunes library, when it shows up in the list, create a playlist with just the Aiff title in it and burn the CD in iTunes. If iTunes tryies to convert it AAC, then set the import settings in iTunes to Aiff before bringing in the the Aiff file.
    Toast would be a better solution if you have it, as well as being simpler to create the audio CD.
    You can delete the aiff from iTunes when your done as well as the play list it was a part of.

  • Trying to separate music track from audio track

    Hi all - I've been reading posts, but haven't been able to determine whether there is a way for me to separate a music track from an audio track.
    I have a copy of a television show that aired, where the music and audio tracks have (obviously) been mastered to the point where it's one music channel.
    I'm trying to extend the music a little further without including the people talking. Does anyone know any creative methods that would allow me to do this?
    Thanks so much for your help.

    No...not at a professional quality level. You would need to either collect enough of the music bed where no dialog or f/x are present or obtain the oringal source music - which could be anything from readily accessible library or commercial to no longer existant custom music.
    Sorry...I know that isn't much help.
    From a Non-Pro level...there are really only two tricks:
    1) If there is enough contrast between music and everything else...about all you could do would be to EQ out the ranges where dialog exist. 300hz - 4Khz maybe. But that is also where the definition is going to be in the music.
    2) If the music is in stereo and the dialog is not. You can try to elimate the dialog by inverting the phase of one channel and monoing the two togther. This will leave you with only L-R material. Again, not good enough for professional broadcast...but you can try it.

  • How to remove Access 2007 (MDB) project from Team Foundation using VB6/VBA?

    Hi,
    is there any way how to remove A2007 (MDB) project from Team Foundation using VB6 or VBA? CompactDatabase method doesn't seem to help.
    I need to remove back-end MDBs before deploying the whole project. In other words, the MDBs themselves should remain in TF but I'd like to remove their copies that should be deployed (distribution set). I wrote a simple function for compacting MDBs but it
    doesn't do the trick. When I compact an MDB in Access 2007 I'm always asked whether I want to remove it from source control.
    Thank you very much in advance.

    What are the copies you referring?
    These are physical copies of local MDB files. I can't (don't want) to deploy MDB files that are handled by source code control (SCC) since those files hold information about SCC (local directory mapping). Users might not understand the message they get when
    they open such MDB in Access, eg.:
    This database was named 'C:\Projekty\P1\DB\nP01.mdb' but has been moved, copied, or renamed. Source code control features will be disabled.
    That's why I want to remove the SCC information from MDB files. The only way I know so far is to use "Compact & Repair database" in MS Access 2007. I'd like to point you to http://msdn.microsoft.com/en-us/library/aa155494%28v=office.10%29.aspx (it's
    similar to Access 2007 & Team Foundation):
    Using the Compact Database Command
    In order to take a database that is under source code control and deliver it to a user, you need a way to cut the database's ties to source code control. When you compact a database that is under source code control, Microsoft Access 2000 prompts you
    to remove the database from source code control.
    To remove the database from source code control, Microsoft Access simply removes the Visual SourceSafe properties from the Microsoft Access database and its objects.
    I would like to remove Access MDBs from SCC programmatically so that I can
    significantly reduce time that I spend on deploying the application. In one of our applications there are five back-end MDBs that are under SCC and it takes some time to remove them from
    SCC manually. I have to do it anytime we release new version, even for releases that are determined as testing releases for internal testing within our company.
    Thank you very much for your time.

    Just some quick things to check out for now.
    If the Premiere Elements audio effects are not working for you, please check out the noise removal offered by the free audio editor named Audacity. Have you used that before?

  • How to remove hum from audio?

    I know about these options:
    Audio Enhancements - Equalization - Hum Reduction.
    Audio Enhancements - Audio Analysis - Hum Reduction.
    I may not be using these options right, but they can't help me.
    I know also that I can use the Graphic Equalizer, but I do not know which graph to adjust to remove the hum. Is there a role of thumb? Any YouTube tutorials anyone know? Plugins?

    The hum is my freezer in the background But it is not loud. I just don't like that I can tell that one voice clip ends and one starts because of the background. I have key frames fading start and end of each voice clip, which helps, but isn't there anything else I can do?
    To avoid that, you always record a few minutes of your room's ambient noise (or outside if you are outside). Get a lot of that sound with nobody talking or making noise. You then use that in-between your cut dialogue clips so they flow smoothly.
    You probably have a second or two in one of the clips where nobody is talking and you can grab that bit and copy/paste it in-between your clips.
    Also, FCP X has some room tones built in, in the music media folders. Just search "room tone" and you'll find several. You can pick one of those that sounds the most like the one you've recorded and fade in/out the beginning/end of those clips.
    If all else fails, you can put some royalty free music underneath and put a room sound FX on it to make it sound like it's a radio or TV in the room, in the background. This can hide audio issues well.

  • Removing echo from audio track.

    Hi
    I have audio recorded in a church which sounds great apart from the echo on it. Im at a loss as to which filter, if any will help remove it. Can anyone point me in the right direction?
    Many Thanks
    Adrian

    You may be able to reduce the level of echo by using a noise gate; the results will depend upon the nature and level of echo and also other background noise, but some reduction may be possible. Don't be too agreesive in the setting of noise reduction otherwise it will be very obvious that you are gating the sound and you will end up hearing the background sound coming and going as quite often heard on less well processed movies and tv productions.

  • Export from audio track to burn a CD

    Hello everyone
    I am trying to export only audio from sequence, so i can burn a music CD
    I exported audio to aiff option
    then took the aiff file and burned, but its not playing on cd player
    i chose the export aiff- mix , still did not play
    can anyone help
    thanks
    Danny

    is the sample rate 44.1 (not 48k)
    can you open the track in itunes? (from the CD) then the tracks OK but burned wrong.
    did you burn an audio CD? (as opposed to a data CD).
    Many boom boxes work best with the type of CD labeled "Audio" (as opposed to the type of cd you burn data or audio).
    maybe post in a different forum?

  • Low hum from audio out

    Hey guys, I've got my old iMac hooked up in the living room to be a network iTunes jukebox, and it works fine, but there's this ever present hum whenever the thing is plugged in. It sounds as if it's not grounded or something.
    Is that possible?

    I don't have a solution for the hum itself. However, if it is "noise" on your iMac's output headphone connector, you might be able to bypass it by using USB for output. Griffin Technology makes a device called the iMic. It has audio input and output, and goes through the USB port.
    http://www.griffintechnology.com/products/imic/
    I don't have that product, but I have a discontinued Griffin audio product called the PowerWave (also uses USB), and it works quite well.

  • HELP! "Reduce background noise" changes from audio clip to clip, even though the percentage is the SAME. At my wit's end...

    I am working on a lengthy editing project and am near tears at this point. Any and all advice would be deeply appreciated.
    I am using  a2012 MacBook Pro running Mavericks (10.9.5) and iMovie 10. I have been using the "reduce background noise" feature in iMovie 10, with movies where audio is detached, and I have a series of clips stitched together (the result of editing, or adding voiceovers). I'll add 4% reduce to the first clip, and it sounds great. I do the same to the second clip and it sounds as though the setting is at 100% — even if it's at 0%. In other words, the audio is really distorted.
    I have tried relaunching iMovie and the MacBook itself, to no avail. The first clip is fine, all those that follow sound horrible, no matter how I change the setting.
    Again, any and all advice or suggestions would be very welcome. Thanks!

    I'm not sure if anyone is going to read or respond to my plea, but just in case, I thought I'd better update.  I went into our local Verizon store today and explained my problems.  I was nervous to do so because I didn't purchase my phone there and didn't know if they'd refuse to help based on that fact.  The local store of a competing carrier will not help you if your phone wasn't purchased in their store.
    What I found out was that my method for pulling the battery was wrong.  I didn't realize the phone needed to be turned on when you did that.  I did it the correct way and now most of my problems are gone.  The one problem it is still having is not being able to update from 2.2.1
