    removing a "buzz" from audio

    I am just beginning to learn sound mixing in AVID and the Lynda tutorials really dont cover this. Yesterday I learned how to balance levels and pan, but I am SO lost on audio tweaking. 

    I learned editing using FCP and Soundtrack Pro. 

    Can I get some love?

    You should be able to achieve this with 7 Band EQ RTAS plug-in. The DINR AudioSuite plug-in works very well and easy to use to remove noise.

    Re: removing a "buzz" from audio

    I used the 7 band that comes with the software. Is this really the only frequency modifier in the software? I brought down virtually every level on the 7 band EQ and while it is better, it still has a slight hum.

    I looked at the DINR plugin and it is $995. They cant be serious. I have already spent $5000 on Symphony. There must be an intelligent way to remove buzz, pop and hum. 

    Havent found it yet.

    The AIR Kill EQ worked better. Still, this is very scary to think that solid, slider based eq tools are not in this very expensive software. If I'm off, someone PLEASE tell I'm wrong.

    If you launch the Audio EQ Tool, you will find sliders and a hum buster filter in the fast (hamburger) menu.

    You can create a Notch Filter with the 7 Band EQ that can look like this.

    There are a number of ProTools EQ Plug-in tutorials available. The effect is identical in SN.

    Re: removing a "buzz" from audio

    These are great suggestions, but Im afraid the buzz will be in this video regardless because I cannot remove it. 

    I have scanned the entire range of frequencies and it seems to be present throuout.

    Re: removing a "buzz" from audio

    I sure wish there was a tool like FCP provides. Am I missing it?

     

    Here is a pic of what i need to find in AVID.

    Re: removing a "buzz" from audio

    Correct me if I'm wrong, that looks like an EQ with a lot of Bands. Built into SN I believe the 7 Band EQ is the closest. FabFilter Pro-Q is a 24 Band RTAS Eq plug-in available to purchase.

    There are a number of really good Noise Reduction RTAS plug-ins from a few companies such as iZotope and Waves, but nothing free.

    Noise reduction tools basically work by sampling a section of the clip that has the noise only--such as when a speaker pauses between sentences.   Then the NR applies a specific EQ to eliminate that frequency.     You can do it manually by playing around with a multiband or parament EQ and try to narrow in on the offending frequency, but you need a really good ear.   In my case, an NR tool has been a lifesaver for my tin ear.

    Re: removing a "buzz" from audio

    Putting aside for a moment what video editing software is being used - along with any EQs and plug-ins - any top notch audio professional using ProTools will stand firmly behind the notion that quite often, some clips just can't be fixed.  

    I work with a number of such professionals, some of which are good enough to get $3,000 a day without complaint.  One of them told me once that every single week he gets some client who records somebody with an HDV camera whispering their lines under an air conditioning duct, and the client sees the audio guy's $100,000 mixing room and calls him a moron for not fixing it.

    The tool in Final Cut has a different GUI than the 7-band EQ, but both of them do the same exact mathematical enhancements in the background as a 30-year old guitar EQ petal.  They enhance or dehance existing frequencies.  Sometimes it's not the EQ.  Sometimes the guitar sucks.

    Re: removing a "buzz" from audio

    I would ownload a trial version of Adobe Audition.  It has a very good noise reduction filter where you can isolate the unwanted noise and remove it.  I have used it many times to fix what otherwise would have been totlly useless audio.  If it works, buy it when the trial period expires.  I know this may not be the answer you're looking for in regard to having it as part of your Avid system, but it works very well.
