Is there a home-use, ie easy to use, 'processor' that gets rid of unwanted noises from lps? Some of my favourites eg Beecham's Heldenleben are full of ticks, scratches and surface noise as a result of over 40 years hard labour depsite using good quality albeit 'vintage' replay kit viz Shure V15 in SME. I often find as I believe do others, that the reissues on cd sound less appealing and would be grateful for any advice on what if anything is available to clean up lp sound without losing the sound quality. All suggestions gratefully received.

Any such processor is going to involve digital sampling of the original, so you might as well get professionals with many years of experience, and very expensive hardware and software to do it for you, and then buy the resulting commercial CDs, or in some cases, SACDs.

There have been processors in the past: indeed, one from Shure themselves; the Shure Dynamic Processor (circa 1978, at a guess) but they're all a case of the baby going out way before the bath water: there's just nothing that can react that fast in real time, so that you have to lose a goodly portion of the musical information if you want to lose the ticks and scratches as well. You could do a transfer yourself of course, but you're looking at a long, finnicky process.
A passing thought: you obviously invested a fair sum in your LP playing equipment: are your CDs being played on something at an analogous level? Without spending anything like a fortune, there are some CD players which are designed for people who want to listen to music which are not necessarily those coming from the big proprietary names, and there are pretty simple things that need to be done for any CD player to give of its best: good, clean, dedicated mains power, and very stable, though light, foundation, so a separate wall shelf will be a much better bet than being stuck on top of other equipment in or on a heavy wooden unit. If you're still using the thin connecting cable that came as a freebie with the CD player, that too will do the sound no favours whatsoever. Basic rule of thumb: expect to pay about a tenth of the cost of the CD player at least on cable.
I don't work for any one manufacturer, by the way, but I've been involved in the hi-fi industry firstly as sales, and then as a consultant, for about thirty years: the above comments are based on long experience, and are offered in the hope that I can help you enjoy the sound of your CDs more.

Gradus/Bryn/Ron. Er...personally speaking, this sort of problem can easily be cured by spraying oneself once a week with DDT. (or once a day in my case. )

Yep. Banned, all of 'em. Something to do with rights management, apparently.

He's better than some stuff you purchase (you pair of tinkers?).

You need a good record cleaner: something like one of the machines made by Keith Monks. They really do work.

Bryn Firstly it is not absolutely necessary to do the kind of digital processing you mention, though most processors nowadays would be digital. Secondly, your theory is OK, but sometimes in practice the people who make CDs from old LPs seem to be deaf, and the results are not so good. I agree with you about the theory though, and sometimes there are good results, but not always.

What I use is click repair: http://wwwmaths.anu.edu.au/~briand/sound/It's only fractionally less acurate then cedar or waves restauration, by about 10 times cheaper... I have a homepage (for 4 years now), where I post out of copyright lp's http://docent.cmd.hro.nl/otter/Besides some tricks with tracking, needle presuure and eq settings (does RIAA curve ring a bell?) Click repair is one of the main contributions to the sound.... Note, if you go further in exploring click repair (21 days fully functional for free!), the program sleightly tendens to thicken the upper frequencies a bit. I have made a filter (beside the pre-riaa filters I use) to compensate for that. On my "old" homepage: http://homepages.ipact.nl/~otterhouse/You can hear a very worn and scratched record I cleaned up, sounding ... ahm.. quite nice again... Greetings, Rolf, Netherlands
