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

My pain in the a... is that I have to use nvidia drivers, and had troubles some time ago with them and rt-kernels. Do you happen to know whether I need to patch nvidia support into the rt-kernel I build? (I guess so... just to be sure) thanks! best, M

options for hard real time kernel for raring 13.04

by Marco Donnarumma

Hey all, I just switched to Mint Olivia 15 (based on Ubuntu Raring 13.04). I use quite cpu-intensive puredata patches with processing of 2 live audio inputs on a firewire soundcard through ffado and qjackctl (jack2). Although my machine runs a low-latency kernel and it has been configured for pro audio (I use the realtimeConfigurationScan script), I still get xruns and sometimes qjackctl randomly hangs up making the sound to stop completely. Before, I used to work with ubuntu 10.04 and rt-kernel without a itch. Is anybody still using a rt-kernel with the latest Mint or Ubuntu, or just refining settings etc..? if a rt-kernel is the best option, should I patch mine, since it looks like there are no packaged rt-kernels for Raring? Can't access Abogani ppa, and KXS kernels are available up to Precise. thanks in advance for any hint, or suggestions about what to try! best wishes, -- Marco Donnarumma New Media + Sonic Arts Practitioner, Performer, Teacher, Director.

OT: Terrible open source definition

by Andrew C

Entirely OT, but I had a lecture at Uni yesterday and the first slide was talking about Eclipse and how it's 'open source, so it means it's free to use for both commercial and non-commercial purposes'. Needless to say, I cringed at the "definition". We now return you to your regularly scheduled linux audio related discussions.

pro gear that runs embedded linux...

by Jörn Nettingsmeier

hi guys! i'm sure you all have seen your share of professional audio, video, and lighting gear that apparently runs embedded linux but never mentions it much (unless you happen upon the briefly flashing penguins immediately after booting)... i just came across the midas pro2 (which i have to learn for an upcoming job), and lo and behold, in the manual, midas saith: "The PRO2 uses the reliable Linux operating system." not exactly in the brochure afaict, but in the very prominent first section of the manual. :) other expensive boxes i've seen and used which appear to be running linux: * Allen & Heath iLive and GLD series audio mixers * LAWO mc² series of audio mixers * grandMA2 series of lighting controllers * the DirectOut M.1k2 16x16 MADI router none of these make a secret out of their OS, but it doesn't seem to be an advertising item, either. is it because people are generally disinterested in and/or frightened by the fact that their gear has to have some sort of operating system inside? i wonder if we'll live to see the day where "linux inside" is a hot marketing punchline. i wonder if you guys have seen other pro gear whose data gets shuffled around by industrious yet unseen penguins under the hood? -- Jörn Nettingsmeier Lortzingstr. 11, 45128 Essen, Tel. +49 177 7937487 Meister für Veranstaltungstechnik (Bühne/Studio) Tonmeister VDT http://stackingdwarves.net

New "improved" version at http://linux-sound.org/audio/Tango.mp3 http://linux-sound.org/audio/Tango.ogg Middle section is extended with a bit of new material. Same crappy sounds though, so if anyone wants to have some fun re-orchestrating it (hi Will!) here's the MIDI file : http://linux-sound.org/audio/tango2.mid It's set up for standard GM layout.
