We recorded from the record using PCM compression at 22.050 kHz in 16 bit monaural. The below image is the first 20 seconds of the recording.
In case you'd like to hear it, here's the first twenty seconds of the raw recording. It actually sounds better than we expected. Probably because the record was made when records were still coated with shellac. Vinyl would never have held up like that. The abrupt vertical lines are scratches on the record.
To see them better the vertical zoom has been reduce to 25%.
We can either apply a filter to the entire clip or we can manually delete the pops and clicks but for this tutorial we'll do both.
As you can see from the above image, we have zoomed in very close. The highlighted, selected area is a pop.
Now the pop is gone. We can undo the delete now and try it again using a filter.
Here's the same twenty seconds after the filter has been applied. This is 'Twas the Night Before Christmas edited and converted to Windows Media. Because we sacrificed some of the amplitude in the process of removing the pops and cracks, we punched it back up in the conversion. This was a bad idea and the final recording has a ghost in it. If this was a production job it would have to be redone but we're leaving it like this so you can try to improve it.
