De-clicking in Soundforge or Wavelab

I have recorded some rare tunes of a mates old well used vinyl and there are some annoying clicks over the breakdowns and intros that I would like to erase.
I have been told that there are some plugins for soundforge and wavelab that allow me to do this.
Can anyone tell me where to d/l such plugins and a basic run through of how they work?
Or if you dont need plugins, where is the de-click function and how do you use it.
I dont mind which program it is, I have both.
Cheers

Well, Sonic Foundry sell a set of de-noising effects. Alternative, Waves make a very good set of de-noising effects too (but those are even more expensive than the Sonic Foundry ones I think).
But... just expand the wave form in your favourite editor until you're seeing the individual samples (e.g. 1:1 or greater zoom ratio in Sound Forge). Where there is a click/pop you'll see the waveform is (typically) very sharply peaked and quite different to the surrounding wave form. Just manually edit this bit to remove the peak, easy :) |

Right, here's a beginners guide to removing vinyl pops and clicks using Sound Forge.
1. Open the WAV in Sound Forge (or record the vinyl directly etc.)
2. Listen carefully. When you think you hear a pop/click, zoom into the area in question and rewind a bit. Listen again. I suggest a horizontal zoom ratio of about 1:128 (highlighted in green) to allow you to see almost exactly where the click or pop actually is. To change the zoom ratio, click on the zoom buttons (highlighted in red).
3. Stop playback and place the cursor more or less over where you think the click is. Now zoom in much closer. Scroll back and forth until you see something that stands out a bit and looks different to the rest of the wave. I've highlighted the artefact in red.
4. Move the cursor much nearer and zoom in again to confirm you've got the right area. Here the click should be much more obviously not part of the original sound material. Notice how the click is very sharp indeed and peaks very rapidly - totally unlike the waveform around it.
5. Using the Pencil tool, zoom in a bit more and draw a nice smooth line over the audio artefact. In this final screen shot you can see I've removed the artifical peak and drawn in how I think the original waveform should look.
And that's it. Depending on the source material and loudness of clicks/pops it can be extremely easy to spot, or quite difficult. Practice and patience make for good end results.
Enjoy :) |
