Hey everybody, OpenAV is releasing Sorcer 1.1! Upgraded features such as a compressor and output level provide better feedback in an all new NTK based UI! Existing presets are remain unchanged: the compressor is off by default. Packagers will be happy to know that Sorcer now uses Make, so packaging should be easier. Details available on http://openavproductions.com/sorcer Cheers, -Harry

Some new LV2 plugs

by hermann meyer

Hi I've added some new LV2 plugs in the guitarix git repository lately. There are now beside the already known plugs some multiband plugs, which I've a lot of fun with. That's GxMultiband/ Distortion / Compressor / Echo and Delay. If you want to play with those plugs, you need to build from our git repository. http://sourceforge.net/p/guitarix/git/ci/master/tree/ greets hermann

Mumble Rumble on archive.org

by Dan MacDonald

Hi LA! I've just finished uploading my radio shows thus far to archive.org: MUMBLE RUMBLE 1 - BIRTH RUMBLE - 8/8/2013 Mumble Rumble is an irregular radio show broadcast on Dark City Radio using entirely free and open source software, most notably Mumble for VOIP. This is the debut episode of the show and discusses various aspects of Mumble and why I think its good enough to create a radio show to promote its use and why you should use it too, amongst other things. Please excuse the poor audio during the first few minutes - it gets better shortly after the introduction! TRACKS (edited out) apatt - Village Idiot tRANSELEMENt - King Henry https://archive.org/details/MumbleRumble1BirthRumble MUMBLE RUMBLE 2 - INTERVIEW WITH FALKTX - 15/8/2013 Mumble Rumble is an irregular radio show broadcast on Dark City Radio using entirely free and open source software, most notably Mumble for VOIP. Mumble Rumble was honoured to have legendary Linux audio hacker falkTX as its first ever guest for Mumble Rumble II. falkTX gets quizzed on his distribution/ repository KXStudio (as used to power Dark City Radio), his DISTRHO plugins, his plugin host Carla and much more! http://www.darkcityradio.com/ http://kxstudio.sourceforge.net/ https://archive.org/details/MumbleRumble2InterviewWithFalkTX MUMBLE RUMBLE 3 - MILES JOHNSTON INTERVIEW - 12/9/2013 Miles Johnston has not only played a significant role in both UK pirate radio (by setting up Kiss 103) as well as conventional broadcasting through his time at the BBC and SKY; he is more well known today as being one of the UK's leading researchers into UFO's, abductees, mind control and a whole host of other things that we're told don't exist, if we are aware of them at all. The main outlets of Miles research have been his Bases series of videos which started in the mid 90's by focusing on exposing the UK DUMBs (Deep Underground Military Bases) and more recently he played a major role in the AMMACH project, with which he is no longer involved. This show documents Miles first use of Mumble which he utilsed to express his feelings and notable memories of AMMACH, the media (including non-humans at the BBC), supersoldiers, implants, the Large Hadron Collider and much more! https://archive.org/details/MumbleRumble3MilesJohnstonInterview

[A bit HS] [Art & Logiciels Libres] Groolot & Sandra Guillen finalistes des Jeux de la Francophonie cat. Création Numérique - A diffuser]

by Aurelien

Hi all, Below is a message, written in French (sorry, if someone wants to translate it, don't hesitate) about two AMMD artists who were designed as France representative for 7th Jeux de la Francophonie (kind of Olympics, but only for French-speaking countries, and having artistic parts too) in the category Digital Creation. They're free artists, they publish their art as free art, and they do use free softwares for this. Finally, groolot also develops free software for stage pruposes. And they're now finalist for this challenge. There is still only 3 countries in the row, so they're now ensured to get a medal. I thought it might interest you. If you read french, there also a french article about this on linuxfr.org: http://linuxfr.org/news/plebiscite-une-oeuvre-libre-en-finale-des-jeux-de-l… Enjoy -- Aurélien

timing issues when using ladspa plugin 1769 click

by Rusty Perez

Hi guys, I'm using plugin 1769 in Nama, based on ecasound. Here's the scenario. I'm recording one track. When I begin recording, the click starts right on queue. I play along with the click. But, upon playback, when I press play, the click clicks repeetedly several times as the playback fades up and my recorded performance is no longer in sync with the click. Again, to reiterate, when I record, the click starts as I start the recording engine, but upon playback, the click sortof studders as the playback fades up, and then the click is no in sync with my recording. Thoughts? Thanks! Rusty

Re: [LAU] options for hard real time kernel for raring 13.04

by Marco Donnarumma

Hey thanks all for the advice. I also learned a lot more about kernels :) Sorry if I didn't get back to each of you, I took notes of all your suggestions and I will test both patching the nvidia driver and use the pae kernel. I still can't get the kxstudio kernel after editing manually the apt sources though. I'll report back! best, M

mastering dilemma

by Brent Busby

I'm going about the process of trying to learn what goes into commercial mastering (yeah, I know...), and one of the conundrums I've run into is that while most commercially produced music has a particular sort of common EQ curve to it, I have to really force myself to try to want that curve when I'm mixing. Really, it just sounds cold. Almost anything sounds better (at least on good speakers) with less cutting around 120-180Hz than most CD's seem to have. And it really must be the result of EQ cuts too -- apart from my digital Yamaha SY99 (which sounds pretty cold), I don't think I have any instruments in my whole studio that could produce sound so anemic in the low mids as what I hear on CD's without *lots* of cuts. When it comes down to it, there's almost no instrument that really sounds like that. So, my dilemma is twofold... 1) To use spectrum analyzers and careful listening to try to understand the "tone" that the commercial mastering world has apparently agreed on, and 2) To figure out why I would want that. On most decent speakers, it seems to sound thin and lack authority. It's terrible having to cater to the lowest common denominator. Anyone else have this problem? Ever wish you could turn up those low mids just a little bit more and get some power underneath? -- + Brent A.

Re: [LAU] options for hard real time kernel for raring 13.04 + nvidia

by jordan

I don't use Ubuntu/Debian but I do use Linux-rt + nVidia, in all of my H/W. So i thought i would clarify a point or two; > Found some suggestions about patching the nvidia driver with some > custom> code here [1], but the driver they use there is quite old. And last >time I had fiddled with nvidia driver it was the most painful experience > ever..:) > >Did you try the patch in my Github repository? You can download it with: >wgethttps://raw.github.com/AutoStatic/nvidia-rt/master/patch-3.0-rt-nvidia.… This above patch only works for Nvidia driver < 325.xx ... 1. For Nvidia's newest drivers ~ you need my nvidia325xx-rt patch; http://sourceforge.net/projects/l-proaudio/files/nvidia-325xx-rt.patch/down… (for me, this patch works fine on 3.8-rt and 3.10-rt. haven't tested anything older... I'm sure it's fine). When building the kernel module (don't know where this is done in Debian/ubuntu) you must ignore the PREEMPT_RT check in nvidia's installer, something like this; " make IGNORE_PREEMPT_RT_PRESENCE=1 SYSSRC=/usr/lib/modules/"${_kernver}/build" module " 2. I've also made available a patch for 319.32, patched for kernel 3.10 support (which then can be patched with the old rt patch, above "patch-3.0-rt-nvidia.patch"). - This is mainly for people who've experienced regressions with the 325xx nvidia driver, Patch is here; http://sourceforge.net/projects/l-proaudio/files/nVidia-319.32_lk310.patch/… I've also started a thread @ nvidia's dev portal about nvidia-rt; https://devtalk.nvidia.com/default/topic/572468/linux/nvidia-325-15-linux-r… There aren't specific distro instructions, but a general "run down", instead. I don't know how different distros package nvidia, so it's beyond my own scope...and Since, i only use Archlinux, it is the only distro that i personally am concerned with. + anyone can see how Archlinux handles nvidia-rt by either reading through Arch's PKGBUILD in AUR; https://aur.archlinux.org/packages/nv/nvidia-rt/PKGBUILD ... then find out how to made your own distro apply what is needed. cheerz Jordan
