Scratch filter

[Anders F]

I am transfering some old LP-records to CD. I use
Audacity which works well but I am missing one
function, a filter that removes that irritating sound
from scratches.

Does anybody know some filter program, free or
decently priced?

Thanks in advance
Anders

What about under the Effects Menu, Click Removal. I've not tried it
though.

The key is to use an arm and cartridge combination that is well damped. This
means a single pop only lasts for one cycle, instead of ringing on and on for
dozens of cycles.

Is your problem actually surface noise, or is it individual clicks and pops?
I would be more apt to try and correct the problem with proper cleaning in
a vacuum machine and using a well-damped arm before trying to turd-polish
after transcription.

I have been using this application for several years and I have to say it does a
great job.....

http://www.delback.co.uk/wavrep/

It will do the recording and remove clicks, scratches, pops, rumble and hiss as
well as having a waveform editor for really persistent noises and a 'decrackle'
filter. I have been able to restore some pretty awful discs that I originally
thought could never be recovered (but it did take quite a while to do as I had
to make a lot of manual edits!)

Like most software there is a learning curve but once you get used to it you can
clean tracks up surprisingly quickly. It has an 'auto' mode that will remove
most of the obvious faults and then you can manually edit the track to remove
the remaining problems. You can either record a single track from an album or
record the entire album and then assign split points to fall in line with CD
block sizes.

The cleaner you can get the disc before you record it the less work you have to
do cleaning it up via software. I have found that washing the disc under tepid
running water using a *soft* sponge loaded with dish soap really gets the years
of built up crud out of the grooves with no ill effects to the disc. Just make
sure you do not get the label wet! ;-)

I am not affiliated in any way with the software, just a happy customer, and
once you have registered the software all the updates are free.

More precisely, a wideband pickup and a relatively dead arm. Unfortunately,
you won't find this combination in inexpensive equipment.

Have you thorougly cleaned the LPs with (say) dishwashing liquid? That will
get rid of a lot of noise.

You might also look on eBay for a Burwen TNE-7000A click remover.

It is a Java-based program which can remove clicks and bigger
schratches quite well. Don't forget to (skilfully) wash your records
first.

I had not thought of that but now I have tried and I can not make it work

My problem is some records I let a "friend" borrow and now
have some very ugly scratches. Most of my records I have
managed to keep out of harms way.

Those are clicks and pops, and you can probably fix them by hand with an
editor.

To some extent, you can go through with a dental pick and a hand microscope
and fix them on the original record before transcription too.

Being sometimes a bit clumsy, I'd do a transcription before and after
messing with the grooves!
