filtering noise

glad to see the new audio forum! -

Im currently exploring audio in more detail - i record with a canon 7d, and purchased a Rode videomic condensor mic, to improve on the sound.

My next step is to get the zoom H4n - and rig up a recording system that is monitorable at least on a headset.

I currently filter noise with audacity, but was wondering if anyone can recommend an audio prog that is reasonably priced that may give me more audio filtering ability - reasonable at this stage is under 200.

I use the http://www.goldwave.com/. In my opinion this program is very good, very configurable and with very reasonable price.

Im not an audio expert, but recording audio with the 7d. Is that gonna work? I know it records sound, but is it good enough for audio "clips"

Eddie, I think your right it isnt good enough alone for audio - the audio on the 7d basically blows chunks, thats why ill be taking the baby step up to the zoom h4n. lots to learn before I start throwing money at this side of the "lens" lol

What exactly are you trying to filter?

Hi Tobydalsgaard,

The 7D is notorius for noise, even with a manual lens, and no IS on it hisses, crackles, etc, if a bug flies by the rumble from the wind is like thunder.

the rode resolves some of this, but not all.

I dunno man..

Just buy the Zoom and do a manual sync. If the audio is truly that bad (where a bug sounds like a rumble and wind sounds like thunder) why try and fix it? I mean, for all your effort to "fix" something that's crap to begin with, why not just invest in something that will give you workable audio?

SWEET, AN AUDIO FORUM!!! Haha, alright now that I got that out of my system, artmyth, for filtering out noises such as wind created by a breeze or by a fly, you want to use what is called a "Low-Cut" / "low shelf" / "high-pass" filter (those are all the same thing with different names. Anyways, wind creates LOW frequencies which are very very loud, and if the audio in your clip is a human voice, you don't need the super low end produced by wind. If there is an option in the low-cut filter for adjusting, you want to "cut" frequencies below around 120hz-150hz (use your ears to decide, since the more you take away, the more "processed" the sound might become). I use ProTools LE with the MBOX 2, which cost around $375, but I think they have cheaper versions. Plus, for simple filters that is most likely total overkill. I've used Sony Soundforge which is a decent program, although I'm not sure how much it costs. Most importantly, shoot double system (meaning record audio onto a separate device, such as the Zoom H4 you mentioned) and do not just throw the mic on top of the camera (unless you are "running and gunning" of course); for superior sound, put the mic either on another stand as to not pick up all the sounds associated with the camera, such as lens movement, exposure controls, etc. Check out this clip...https://www.pond5.com/stock-footage/661580 I videographed the bees first, then recorded the sound separately at close proximity yielding high quality audio.

That wild bee-hive is 'sweet' ;)

thanks for the information, Ill check these out - thanks for the clarification on lowcut, low shelf, high pass - and researching was getting a bit confusing on those terms.
