I'm mixing an indie film where the sound was so poorly recorded. Basically, it peaks-distorts ( recorded level was way too hot ) in many places. Is there a plug-in or something to ease off the crakling resulted from the distortion. I have the Waves and Waves arts restoration but it does not help at all. Thanks
You're pretty much screwed but there are some tools that can help. Like soundeziner said you can clean up some of the distortion with the pencil. It's a long painfull process and sometimes can sound worse then the distortion itself, but worth a try. The other option would be to use a plugin like the Waves De-Crackle. I know you said you've tried it, but I've had some luck using it in the past. You have to put the faders to the roof and then run it through a few times. It generally will always make at least a small improvement. The other option is trying the noise reduction bundle from Izotope called RX. I recently downloaded the demo and thought the whole package sounded really good. So much so that I ended up buying the bundle. Give there de-clipper a try, it might do wonders.

I will second Izotope RX. They had a great demo at AES and I downloaded the demo version as well. It sounds great and is relatively simple to use. The cool thing about it is you can listen to what you're removing to make sure you don't remove something you want to keep. I just used it today on some nasty dialogue recorded on a research ship in the middle of the ocean. There is a little waver in the dialogue but it had a big job to do removing the diesel engines, waves, and motors of some research equipment.
Its a long shot, but check the original tapes. If the movie was shot HD or DV, and if the editor wasn'tt paying attention, it can be captured too hot. On a few occasions I have gotten location audio that sounded terrible and by luck I heard the original tape and that was the case. Now pain to re capture the proper audio after the edit was done, but it was easier than the pencil tool or ADR
These are all fine suggestions. I relay to people that often trying to correct distorted audio is like trying to unburn an overcooked chicken. Your best bet is likely lots of ADR and foley, (recreate a reasonable facsimile of the original chicken). I've worked on films so poorly recorded that we had to ADR the whole thing...which is about as pleasant as an appendectomy without anesthesia. Good luck
I did a film with a section of TOTALLY CLIPPED audio from an onboard cam. I fixed it with Wave Arts Noise Reduction. I zoomed in and processed lots of small areas and did some selective gain reduction.
At the end of the day the director was really pleased.
Thanks everyone for your valuable inputs...i just downloaded IsotopeRX, i will give it a try.
BTW, is there a big advantage in owning the Advanced RX version. Obviously, it has more control and parameters to fiddle with, but from experience, i find that is not always a better thing.
Not much you can do really .if the dialouge is clipping and distorted .its prety much game over .ADR is your best bet way to go .soudsoap.bnr.or the waves restoration bundle wont help if its been badly recorded
Yes,the introduction of DV cameras was not good news to us in post sound. Everybody just drove into the red and digital clipping on a grand scale resulted. (oh and the cameraman now does the sound of course!)
I was getting OMFs on CD-Rs and realised that the 'all bits' used up meant that the CD-R burning did make the square-ing even worse. Do get Hard Drive transfers and I agree that going back to the source tapes can be good move.
I'll also take a look at the RX mentioned, but so far I use De-click and De-Crackle. You do have to take repeated bites at any clipped peaks with them though.
just for the record, (no pun intended), there is a Noise Reduction package from the makers of Sound Forge that includes a de-clipper. It supposedly calculates what the clipped peak would have been like from the trajectory of surrounding samples. It rounds the top of the reconstructed peak, pushes it back down into dynamic range, and limits the areas around the peak to make it sound more natural.
I haven't tried it, but I was tempted. the thing that turned me off about it is that it comes as DirectX plugins. I ended up just manually resculpting the peaks in Cool Edit 2000 using the spectral and waveform views and the envelope tool. It was time consuming but it worked.
