Frequency chart for ambient sounds +

Jun 6, 2012 8:16 PM

Tags: #audio_frequency_chart

I've been googling like mad for a frequency chart for sounds like a door slam, car horn, compressor rumble, etc. Things that you might want to isolate and diminish from a location sound track. All I can find is instrument frequency charts. I know sounds can vary, just trying to get a ballpark idea.

    Those things are best controlled on the set, rather than trying to remove them in post.

    No doubt, however those of us who are not professionals and just do "home movies" don't always have the luxury of a controlled environment.

    I appreciate the "do it right so you don't have to fix it in post" approach. That's my training, but filming in the developing world has its challenges that cannot be avoided, especially with a team of one, with limited budgets.

     

    I saw a frequency chart like this many years ago, just can't remember where. Continued googling has not shown much including looking on the AES site and other pro audio related sites that I can find.

     

    It would be interesting to hear from an audio technician that works a lot in documentary.

    what you're trying to do is really hard to do...cancel out stuff with similar but not exact sound you got that you dont want..probably impossible..  but low and high filters might help a bit and here's some stuff I got from googling " foley artist frequency "

     

    http://smcnetwork.org/system/files/smc2011_submission_111.pdf

     

    http://www.freesound.org/

     

    2nd link is from first pdf link..

     

    I've used some of the sounds on that freesound org ...hunt around and you'll find lots of stuff...

     

    good luck !

    Yes, "cleaning up" Audio can be painstaking, and time-consuming. This ARTICLE goes into a bit of detail, but even with a handful of filters, and EQ, it takes critical listening, and minute adjusting.

     

    @GlitchDog,

     

    After a bit of such work (and maybe some saved filter/EQ presets), it does become a bit easier, as one learns what to listen for - essentially the aural end of what you are asking for with the frequency range charts (have never seen such, but maybe if you also ask on the Audition Forum, some of the audio engineers there, can point you in the right direction?

     

    Good luck,

     

    Hunt

    Thanks guys, this is all very helpful! Though we are newer to Premiere I now have two EQ presets to trim out some hiss from interviews.

     

    I've learning a lot about sound over the years from books, seminars and audio people, but still have always felt a bit handycapped in this area. I was thinking seeing a frequency chart to show how various sounds can overlap, even male/female interviewee voices with potential ambient location sound happenings, would deepen my understanding/education. If that makes any sense. Look forward to checking out the links. Thanks for taking the time to offer them, much appreciated!!
