How do I get rid of background noise?

Trying to get rid of background music from a speech given. The speech was infront of a mic so that audio is strong. Just need to get rid of the music in the background. Any suggestions?

FYI: Much of noise reduction depends on what "type" of noise you are trying to eradicate. E.g., in a sample piece of footage involving an interview with a lady in a cafe, there was a busy street outside.. just at the point in a critical line in her speech you could hear a break squeal in the background, you know, that high pitch squeal you hear from disc brakes from a vehicle!
Interesting bit! > What I learnt was that I could visualize the squeal frequency in the spectrum analyser.. it was very clear to see the offending noise.. then to eradicate it (and ONLY the break sequel) Using the mouse pointer I could simply select the spectrum print of the actual noise and press Delete! Amazing! Very quick but most importantly, absolutely no effect of the dynamics of the surrounding audio. Very Cool!

  • In Adobe Elements, how do I get rid of background noise in my audio?

    What version of Premiere Elements are you using and on what computer operating system is it running?
    Classically USB microphones do not work with Premiere Elements (any version) for use with its Narration Tool. Have you found otherwise?
    Where is the noise - in narration clips produced by the Narration Tool or from imported audio files added to numbered Audio Tracks and/or soundtrack?
    From what you wrote, it appears that the audio noises are confined to the narration being produced with your microphone and Premiere Elements Narration Tool. Is that correct?
    Under fx Effects there are audio effects that you can explore to reduce noise. See Reference Effects Adobe document for a description of the fx Effects audio effects.

    If you use the same microphone and create your narration in Audacity and import that narration into a Premiere Elements project, do you get noise in your narration?
    Audacity: Free Audio Editor and Recorder
    Besides making sure that your microphone is compatible with Premiere Elements, have you evaluated your narration recording techniques...how close are you to the microphone, room noise level while recording, etc.

  • How do I get rid of background noise when recording a slideshow??

    Im trying to record a slideshow for keynote with music soundtrack coming in time with the clicks, but even when I plug a mike cable into what looks like the mike socket, i still hear background noise such as me tapping the key board...
    any tips? Is there a way of turning the microphone off completely??

    Go to System Preferences / Sound and click on the Input button. You should see two items listed in the device menu: the Internal Microphone and Line In. (There may be others if you also are using your USB or Firewire ports for input devices.)
    Select Internal Microphone and adjust the Input Volume control to the far left (minimum). This will mute the computer's internal microphone.
    Then select the Line-In (or other device) and adjust the input level as needed to make your recording.
    Good luck.

  • I'm using movie program how do get rid of background noise and put music over top of video

    I'm using movie program how do get rid of background noise and put music over top of video

    Niel,
    Thanks for your suggestion about using RCDefaultApp. I am hesitating to do this because it seems like I'd be installing still another piece of software to fix the original mistake---downloading Reader.
    About 20 years ago I maintained---with considerable handholding---UNIX systems of various sorts. Can you suggest how I might find the plist that seems to require changing?
    BTW, Preview is called whenever I open some random .pdf file. The problem appears when I want to get a file from the web. If the site permits a "download" I can get the file, but if I want to "view and print" the file, the evil dark-grey Adobe screen appears with the whirling black ball. Then Safari quits. I'm wondering if the reference to Reader is in a "cookie" sent from the website, when I first was installing Reader. Is this possible?

  • How to get rid of background noises?

    what would be the best way to edit a track to get rid of background noises like a guitar bleeding into the vocal mic?

    Three things to try:
    1) Insert the Noise Gate plug-in. Use judiciously, or you'll truncate the vocal (breaths, lip noise etc).
    2) Use 'Strip Silence' on your vocal track (Audio Window)
    3) Double-click on vocal track (Sample Editor) and using the change gain function, reduce the spilled noise in sections that are bothering you.
    Which one works best for you depending on your track, but if the guitar bleed is too loud +while the vocal is present+, there's not really a magic filter to get rid of it.

  • Getting rid of background noise when recording cassettes

    How do I get rid of the hissing background noise when I transfer cassettes into GB?

    Thanks - this is totally new to me. What sort of software do I need to clean up the noise after the fact? I'm dealing with old cassettes and a cassette player with no dolby option.
    there's a bunch of applications that will clean up or "restore" noisy audio, and they range a lot in price and features. Here's a few options:
    Bias makes Soundsoap 2 (around $100) and Soundsoap Pro (around $550). Bias makes some great audio software, so Soundsoap 2 might be more than adequate.

    If you think you might want to use Roxio's Toast 10 Titanium Pro (around $115), it comes with a version of Soundsoap included. As long as you don't need the features of a dedicated noise removal application, it's a pretty good deal:

  • Help to get rid of background noise in GB3 when recording voice on Sony mic

    I am recording my voice into GB3 using a Sony ECM-MS907 condenser microphone connected to the line-in input on my iMac (core duo 20"). I use basic vocals with no effects.
    My voice records fine but there is a background noise underneath which I can't seem to get rid of. It is also present if I use the built in microphone. I don't think it is room noise as it is pretty constant throughout.
    I have added a backing track which helps to mask it but this is not really satisfactory.
    Any ideas how I can record without this apparent interference?

  • How can I get rid of background music on Safari

    There is a backgrund music on my Safari and I cannot get rid of it ... Please help

    That must be the websites you're viewing, and not Safari itself.
    Doesn't your keyboard have mute, volume down, and volume up keys (as F10, F11 and F12 ?)
    And BTW: this is the forum for the Mac Pro, not the MacBook Pro...

  • Getting rid of background noise

    I've got some interviews that were done in a factory, and there is a constant hum of the factory machines in the background. I've tried a number of different audio filters in FCP, but I can't get it right.
    Any suggestions?
    Thanks,
    Eric

    Aside from the previous helpful suggestions:
    Expander Noise Gate Filter can be helpful for this. Try the threshold at about -15 and the ratio at 1.5
    Adjust the threshold and see what happens. I wouldn't adjust the ratio that much.

  • How do I get rid of background color in shortdesc

    Every time I remove the background color from the short.description paragraph tag, it comes back when I reopen FrameMaker. I don't want any background colors in my short descriptions.

    Ah .. FM10 and DITA 1.2 .. too bad, you're in for a bit of a chore.
    The 1.2 apps are here .. AdobeFrameMaker10\Structure\xml\DITA_1.2\
    Unfortunately, there are lots of them, and it's not immediately clear how to approach things. Opening an XML file in Frame requires a structured application in order to define the valid document model and to apply the proper formatting. The formatting is applied by an EDD, which defines the mapping from elements and associated styles which live in the template (the EDD itself is embedded in the template as well). The structured applications are defined in the structapps.fm file (of which there are two). One of these can be seen when you choose the Structure Tools > Edit Application Definitions file (this lives in the user's "app data" area), but another is at AdobeFrameMaker10\Structure\structapps.fm (this is the "core" structapps file). The two files define the available structure applications, any definitions in the user's file override those in the other file (I'm pretty sure).
    So .. when you open an XML file, Frame scans the structapps files for matching doctypes, if only one is found, that app is used. If multiple matching doctypes are found, you are presented with a dialog that lets you choose from the available apps. If you didn't select an app when opening the file, you'll need to look in the structapp files to see which one was used for your file. The root element in your file defines the doctype (as well as the Public ID). If this is a "task" topic, you'd look in the structapp files for matching apps that support the "task" doctype (if you're using DITA 1.2 you'll be looking for a DITA 1.2 task .. I'm not totally clear on how FM differentiates between the two). In my installation the DITA 1.2 definitions are in the core structapps file, but it could be in either place (or both).
    Once you locate the structure app definition, it will have nodes that define the Template, the DTD, the ReadWriteRules, and other things. You're just looking for the template though. If you're using a "task", for DITA 1.2 that's likely to  be the DITA_1.2_task structure application .. the template is located at ..
         $STRUCTDIR\xml\DITA_1.2\app\technicalContent\template\task.template.fm
    where "$STRUCTDIR" is the location of the FrameMaker\Structure folder (or possibly defined differently in the maker.ini .. but that's a different issue).
    Editing this one file will affect the formatting of future task topics you open. You'll have to do the same thing in the other corresponding topic type templates to affect all of the topics.
    In previous versions of Frame, it used the "ditabase" model for authoring and publishing. This encapsulates all of the models in one file making it much easier to maintain. This model is more parallel to the DITA model, but will be a real nightmare for people to customize. I'm not going to begin to try and explain how you'd clone these apps to make your own, although you can read a document written for DITA-FMx and DITA 1.1 that gives you the fundamental process ..
         http://docs.leximation.com/dita-fmx/1.1/?ditafmx_cloningtapps.html
    I'm hoping that I've explained this correctly .. I'm still trying to wrap my head around it myself.
    Cheers?

    How can I get rid of the dark area on top one third of my iphone screen which spoils my background image?
    It seems this problem is caused by the software to increase the readibility of upper letters (clock battery etc.) It be nice to leave us the control of choosing background letter color too if we are using brighter images or darker images.
    I'm using iphone 4s and it appeared after I updated to new patch. 7.1.1.

    how can i get rid of a blue screen background on my MacBook Pro

    Hi Heidi,
    Do tou mean it only boors to a blue screnn???
    If 10.7.0 or later...
    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
    If that doesn't help Reinstall the OS.
