Canon 7D Audio Salvage?
on Mar 27, 2014 at 12:49:53 am

So I recorded an interview with the Zoom H4N - came out perfect….but then I erased it. That was a sad day. So now I'm stuck with the sound out of the camera. I'm working in Audition - what are the frequencies or techniques to utilize to get this stuff sounding halfway acceptable? Is it even possible? I got rid of the ambient with a noise print but I can't seem to fight this brutal midrange hollowness. To make matters worse the room was a loft with tile floors. I'm cooked right?

how did you erase the zoom.
if you reformatted then yes youre goosed.
If you have made any other recordings then youre likely goosed

If neither, and you just, for some reason that you wont be able to understand yourself, deleted the file, then it will still be on the card and a data recovery place should be able to get it back.

It will cost you, but a cost to the wallet is usually the best way of cementing the learning process so you dont make the same mistake ever again.

Yeah reformat, but I'm interested in knowing how to somehow take the 7d sound from the camera and make it sound decent. It's full of midrange, but I feel like it's possible to make it sound much better. I thought someone might have been down this road and had some tips.

Well, DLSR sound awful.
If its full of mid then eq that back, buti dont expect it will reveal anything sounding less horrible. They just are.

Peter,

We recently proved that Canon 5D Mk iii audio from a Tascam DR-60 D was very acceptable. We had to lower the mk iii input gain and adjust the DR-60D line out wheel to get proper level on the camera, but it worked.

I think the trick there was to use as little of the mk iii gain structure as possible.

Hi Ty
Im pleased youve had better experience than me in this field, and I trust your comment on it, but Im just not a fan.

I think the only thing that will make me a fan is a re think on the importance of the audio facilities in these cameras by the manufacturers.
I find the mic input circuitry to be harsh and edgy, I dont do mini jacks full stop, Id need the audio controls to be made available on wheels where an operator can get to them all the time, and Id need XLRs, switchable mic and line inputs and powering.
Basically I dont like audio being a poor relation, but Im happy when people get acceptable results, for them.
Many times have people brough DSLR audio to my mix studio saying theyre happy. All I do is book and ADR shoot.

Peter I wholeheartedly agree with you, these days I don't even want to send a 'guide' track to DSLR after being caught out by a lazy editor / producer using the DSLR track rather than doing the right thing and syncing the separate audio track....

Yes, but once you are asked to adjust and rehabilitate these god forsaken tracks what's your best bet? That's what I am wondering. We all know they suck, but what to do when they are in the lap?

Any change of posting a snippet of what you've got? Perhaps 30 seconds on youtube.

Izotope RX will be able to reduce some of the background general noise.
Dont go too hard on it or the audio will go "watery"
Did you have a window open? Sounds like it?
Youre lucky the camera was so close.

Peter,

If you heard our mk iii tracks, you'd never know they were recorded on a DSLR.

Granted, we used a TASCAM DR-60D as preamp.

Yes, I think its always been the pre amp electronics that have given me the biggest sonic objection whichis ALl that really matters.
This is ofcourse completely aside from the fact that they use mini jack which makes me hurl.
