The results I can get from what are fast becoming basic tools on other platforms outperform anything I have been able to achieve on Linux by a fairly wide margin including GWC. Not to mention the benefit of running such restoration in realtime in Ardour as opposed to GWC:) Seablade ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

Shouldn't such situations be avoided by 1. Giving the new plugin version a new unique ID so it can't be mistaken for the old one (and vice versa) and 2. Making sure that installing the new version does not remove or hide the old one. Since the new version is not a bugfix for the old one but actually something different this seems to be the logical thing to do. That way any existing sessions will just go on use the version they knew. It's then up to the user to update his/her session (or not).

If it is _noise_ (a continuous broadband random signal), then frequency domain methods should be able to reduce it. If it is _crackle_ (short spikes) then time domain methods will have a better chance. Also the remark that the problem only occurs 'while the music is playing' adds a bit to the puzzle... It would help to know the origin of the the 'noise' or to have a sample of it.

(Version 3)... Then load a project created with version 1. Does the host in THIS situation set the new port to it's default value, I doubt it. More likely it 'restores' it to some invalid setting. Do you want a fragile, crash-prone, plugin ecosystem?, or a robust one? The plugins in CAPS clamp all control inputs to the valid range. Whatever the host sends, including inf and nan, there is no "invalid" setting. Moreover, the plugins will not crash even if run without connecting their control ports at all. The above experiment, by the way, is exactly what I did, and it did not cause any abnormal behaviour: no crash, no segfault, no bus error, no assertion failure in any part of the executed code; no inf or nan, not even a single sample value of or in excess of 1f absolute in the audio output. I think your fear of a fragile and crash-prone plugin ecosystem is unfounded and exaggerated. I Agree with Paul on this one. I can very well see how a host author would want plugin port signatures to be stable, and I was never happy about invalidating this assumption. However, the evolved plugin doesn't even break ardour or its session files, so the pragmatic thing is to just get on with it and not waste as much breath on a triviality like this as we do now. No, the pragmatic thing to do is not deliberately break your plugin when several knowledgeable people have pointed out that doing so can cause countless problems. One test with one version of one host certainly does not outweigh that.. particularly when one of said knowledgeable people is the primary author of that host! -dr ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

Re: [LAD] FW: Frequency Space Editors in Linux
It depends on what you need to do precisely. To be clear, the frequency dependant functionality of the noise removal in the windows programs mentioned, only appeared in Adobe Audition (1.5 I believe) after Adobe had purchased Cool Edit from Syntrillium(sp?). Before that Cool Edit had used only a sampling based process. And really their frequency based process is only a noise reduction process IIRC, meaning you essentially remove that frequency range for that period of time, I think it is a bit smarter than that, but the basic concept is there. Al this being said, if there is a crackle, there are some specific algorithms that exist that are _not_ the broadband noise reduction that you seem to be looking for(In other words are specifically for declicking audio), that may be of more benefit. However in all these areas of restoration, Linux is sorely lacking. You can try GWC, but I was never impressed by it or Audacity for restoration work. Sadly if you are depending on restorative work, your best bet is either to use another platform at this time, either another OS or via realtime hardware based solutions like CEDAR if you can afford it. Alternatively you can attempt to run other plugins/software via WINE on Linux, whcih I have done in the past with mixed results. But really to my knowledge there are no good native audio restoration tools on Linux. I am currently using the WaveARTS MR Suite on OS X for this work myself, though since it is machine based authorization(not iLok), and several of their plugins do run on the receptor hardware, it might be worthwhile to try to run it via ArdourVST/Wine and see if it can be run on Linux. This is on my TODO list as I slowly progress to Linux again full time for production work, but is not something i have had time to do yet.

Hi Mike, Forwarding this to the list where users and developers might be able to assist. Hope this helps! Best wishes, Ico -Original Message- From: Michael Van [mailto:m_vanwag...@yahoo.com] Sent: Saturday, April 09, 2011 12:44 PM To: i...@linuxaudio.org Subject: Frequency Space Editors in Linux Hello Linux Audio, I just wanted to find out if anyone know of any Linux programs that do sophisticated noise removal from recordings, like the frequency space editing process of Windows programs, Adobe Audition or Cool Edit. I wondered if there is a plugin for Audacity that might do it. I need to use something other than standard noise sample removal plugins because the crackle is only present when the music is playing, not present during quiet stretches.
