Audio clipping/ distortion removal software?

v-un-v

I've got a rather lengthy track that has a bit of clipping on it (digital I'm afraid). Does anyone know of any good software that can take the clipping out (or at least help to remove it). I used to use Steinberg's noise and click removal VST plug in, and this was excellent for cleaning up stuff, but that was 10 years back. Can anyone recommend anything else?

You may want to have a look at SeeDeClip by CuteStudio Ltd.. I've not tried it, but it was recommended by several people who ought to know. Cheap as chips too.

I edit clicks & clipping out manually mostly, cool edit does have some tools for it but I find it easier and faster to just redraw the wave forms manually ... as long as it's only a couple of spots of course.

What applications do you use for this kind of manual editing (Mac or Windows)?

Cooledit, on windows, but audicity could do it too (although I can't quickly find a way to make my fav. envelope dip thingy there, but a fade-in fade-out is present and it does sample editing, those will do the trick).

Basically anything that will do sample editing, having some sort of a macro tool is pleasant, I mean something that will allow you make a custom fade curve). Sometimes it's useful to run a filter an a couple of samples, but I don't use that very often.

What Stein mentioned, masking, is useful as well, so cut copy paste is handy. For instance cut a bit of the left channel to repair the right, or borrow a couple of milli seconds here to past it there, you'll need to apply some envelope curves as well.

Oh and when it has cue marks .. I mean I just hit F8 in cooledit to set marks at spots where something is wrong while listening through the track once or twice. Audacity does not seem to do that, but I have an oldish version here.

Correcting a few pops and cliks manually is probably just fine. But a track that has been consistently clipped as a result of a too high level and has lost lots of information and dynamic range requires stronger medicine. This is where the fancy specialist software comes in, attempting to recover the full waveform and dynamic range of the material, not just softening the edges.

This recently got a pretty good review in SOS:

The only problem though with the Isotope stuff is that it tends to come with a hefty price tag- and for one personal job, it isn't worth the outlay. The software that dj suggested only costs a tenner.

The declipping tools in Logic are, well, crap. They are better suited towards being creatively used to make new sounds- honestly!- Because I have done precisely that with them! Shocked

In Soundforge you can do a search for events whose level is equal or greater than -.1db to find all your clippings, then you can highlight them and do a "smooth" tool on them which just carves the sharpness off the corners/spikes. You can also draw in new waves, but I must admit that I'd like it to zoom a bit closer for freehand wave drawing. It only goes down to 1:1 which I think means one sample per pixel. I'd prefer the option of 4 to 8 times more precision.
