Noise reduction plugins?

[folderol]

A friend (recording engineer) tells me you should use a combination of several different noise reduction methods, each only taking it down a few dB, and never attempt complete removal.

I've been doing that with some degree of success, but I believe the result I used to get with that... erm, something I used a year ago (probably Audacity) was better.

Did you try deleting the audacity config files in your /home directory?

Yes, I've tried that, too.

it's only source, no packages.

There's a binary for Windows. You could try running that with WINE. Latency is irrelevant here.

There's a new noise reduction plugin we've been talking about on the Ardour forum. I think it works at least as well as the Audacity noise reduction but it's used as a plugin so you don't have to export your tracks to Audacity.

I have had luck using a downward expander as a noise reduction tool. With the right settings, it will kill all sound in the space between whats above the threshold, while noise is rarely heard during loud sound anyway. I once cleaned up an acoustic guitar recording almost completely this way, without damaging the high end.

This is a very good idea.

Virtual machine with a small distro like puppy running audacity?

Aeons ago I used Gnome Wave Cleaner. It's much better than Audacity, but it got old and I don't think it's actively developed anymore. I'm not even sure it still compiles on my Gentoo, but there should be a Debian package (look for "gwc").
It's not a plug-in, though, but a stand-alone program (and not even jack-ified).

[Luc]

Yes, GWC is available on the Debian repository! And it looks kind of cool. I've been too busy, but will take it for a spin ASAP.

Thank you!

Hi! GWC is so old and unmaintained that it will probably crash rapidly. It did when I tried to use it. There are two serious options Audacity if you like the audio editor workflow or noise-repellent if you like the plugin workflow. Both of them will get you there. Audacity denoiser is really good but it need lots and lots of tweaking and won't provide rapid results and for the case of noise repellent results can be achieved much quickly (shameless promotion here haha ).
