Handling some bad audio in post

[CiPO]

Hi
I am not sure this is the right forum or maybe I need to post in an other section. However I finally managed to test my Oktava/Chiniz mic and being unexperienced with it I managed to record any sort of unwanted noises
I got too much background noise ( we were in a quite bar), some low noice (sort of hiss coming from a compressor/refrigerator) and some bumps due to the people hitting on the table where the mic was standing.
How can I now clean up a bit my mess in post ?
I use Avid liquid but I have also some other audio editing sw.

What's the best way to proceed ?
THX
Cheers

Maybe I posted in the wrong section ? Please, let me know. I can add a few things:

- I used both the on the camera input together with an external cheap mic (sort of backup) and one Oktava/Chiniz with hyper caps. The later capture really too much especially from the back of the mic. I was wondering if maybe I can use some sort of absorbing foam shield on the back of it to limit its sensitivity toward the undesired direction ?

- The sort of "bong" captured due to some hand or finger hitting the table could be maybe simply removed overwriting some background noise on them ? They look like short spike on the waveform

- About some hiss and low freq noise, can I use some filter for them ?

No.

A good editor can help

Yes.

Not really. Well sort of but that isn't the way to do it. I'm going to go out on a limb here and just say you are not getting the mic close enough. Not that big a limb because you say the mic was sitting on the table, generally a bad choice. Use a sound person. You can put sound absorbing material around the mic but it's a bad choice in most cases for a whole slew of reasons and should be done by someone who knows what they are doing. Foam is not a sound absorber to any great extent.

Yes if you know what your doing. I second "get a sound editor" Depending on content and placement you probably will need some more specific tools to really clean that up.

- About some hiss and low freq noise, can I use some filter for them ?

Maybe. Depends on how big a hit it puts on your track. That low freq. noise might well be sitting on top of your dialog. Noise reduction applications are a better tool. But again this is a "get an editor" situation. You don't want to spend the $$$ for the right tools and then spend the time to learn how to use them. You will get better results for less money hiring someone who knows what they are doing.

Hi guys,
thanks for help. It's a no budget video interview and I can't hire anyone .... it's a one man band I am getting one shock mount for the mic (http://www.oktava-shop.com/view_prod.php?id=47) that should help with the vibration.
Then I need to do more tests with the mic distance and mic gain both on the mic itself and on my recording device (Zoom H4)
thx
