Hi!
totally OT...
Hoping there is a mailing list or wiki (or other help forum) for GWC, but haven't found one yet.
I'm working on converting a bunch of my LPs to CDs, and am using GWC (Gnome Wave Cleaner, or GTK Wave Cleaner) to clean up the noise. It works great, but I can't figure out how to deal with certain types of pressing flaws that create a thump every time around.
Anyone know of such a resource?
Thanks in advance!
Fred

I tried to respond directly to Fred, but got bounced. Hence replying to the list even though, as Fred notes, this is WAY off topic.
Wow, does that still exist? I gave up on it YEARS ago. Audacity is far better at removing clicks and pops, splitting into tracks and exporting to FLAC. It also does a great job removing tape hiss.
As for removing thumps - No way I know of to do that. Audacity might be able to reduce the thump by using a high-pass filter set to roll off at 30 or 40 hz, but I don't think it can be taken completely out.
One of the really annoying things I remember about GWC was how it reacted to music featuring a bass trombone. The entire passage was detected as several million little clicks. When GWC got done, it sounded like the musician was playing through a fan. Totally unlistenable. Audacity's click filter can be adjusted to not do that.

yes, it still exists. looks like it gets occasionial maintenance.
Audacity is a great tool, but (according to stuff I've read on the mailing list/wiki) its noise reduction tool is broken. Using GWC, If I take a few samples of lead-in and/or inter-track "silence" and apply it as a noise reduction filter I get an amazing improvement in playback noise, even on a clean lightly-played disk.
I've used both tools for click removal and they both seem to work well. Mostly, I select just the click and minimal space around it and GWC does a great job. (of course, if it's a really noisy old LP then you'd need to run the click filter on the whole thing, but so far the ones I've converted, while being years old, have only been played a handful of times and so sound pretty good with minimal clicks to remove and little distortion due to dirt or wear. I'll eventually get to some of the older ones though, then I"ll need to work harder! :)

Yeah, I've thought of a high pass filter, or a notch filter, but haven't (yet) tried it.
Thanks for the response, Bill!

Bill:
I'm using milter-greylist, so that any site sending mail that is not in its whitelist database will get a 451 response code, which means "cannot accept mail now, try again later" (my own wording). Any modern SMTP agent should be smart enough to try again after a while. Once that retry has been received, that site will be auto-whitelisted for 24 hours, so that sites that send multiple emails a day remain whitelisted and don't have to go thru that hassle.
Fred
If that is not what you got, then I don't know why it would bounce.

Hi Fred - I tried again, and it bounced again. This is not a 451 as you mentioned above, so I did not retry. Here is what I got back:
