Clip Restoration in CEP
« on: December 08, 2003, 06:27:19 PM »
first, thanks for the point in the right direction.

second, here's the prob:

I recorded a show and the clipping is simply occuring during the "snare" of the drums, but it is constant throughout the songs and clipping nonetheless.  Using CEP, I am fiddling with the "Clip Restoration" tool.  After clicking the Help button, I was eventually led to this:

A general procedure for restoring clipped audio while also retaining the amplitude would be:

-convert file to 32-bit

-Run Clip Restoration with no attenuation

-Run Hard Limiter with no Boost, but a Limit of about -0.2dB to bring the restored clipped audio back into normal range.

-convert back to 16-bit if necessary.

I simply tried the Clip Restoration and it appeared to do something good, but I am not sure if following all of the steps above would lead to better results.

Also, no matter what I do, is it better to select the whole show and run these features or just only select the parts where there is clipping?

Any help in the matter is greatly appreciated!!

hehe, just ask your damn question and don't ask unnecessary questions about asking the question! ;)
by the way if you haven't noticed we post plenty of unnecessary bullshit here.
if you're going to be editing the recording on a computer, i think this forum is appropriate.  if you're not sure otherwise, just post it in "ask the tapers"

Okay, so...how to fix a clipped recording.  I've used a plug-in to CE2K before and was not terribly impressed with the results.  It softened the clip a bit, but not a lot.

How severe is the clipping?
What software are you using?

i think soundforge is the best software that i have found so far to fix clipping.  Being new to recording i get a lot of them

I'm probably just going to run some tests myself, but can anyone answer the quesion on whether I should convert to 32-bit first?  Should I convert the whole show to 32 and then run Clip Restoration in the clipping parts?  Or run it on the whole show?  I appreciate any help, thanks!

you would benefit by the 32-bit. by how much?? i have no clue.

in my remastering, i run across various types of clipping.

1. levels are just cranked to hell
2. slight clipping on the high dynamic parts (audible, but not too bad)
3. over compression (i called it "let's-make-our-cd-as-loud-as-we-can-and-not-give-a-F*CK" compression).  listen to Primus' latest "... Act Like Animals"  it's pretty bad.
4. much too hot signal from a +4dB soundboard feed.

there are many ways of correcting (or minimizing) various clipping scenarios. i don't think there is a "one-all" filter that will solve every issue.  

the first thing i do is to determine what caused it.  from there i approach it with different methods of reduction/elimination.
