did the debian devs think they were doing? My music machine is set up precisely as I want it with no spare fluff or eye-candy, and fits my workflow like a glove. I seldom make any changes, but thought it high time I checked for upgraded packages. Up till now this has never been any kind of problem and usually results in some tiny overall improvements. Today was different. Without asking, indeed, without even a warning, they installed GDM, Gnome3 and pulse audio, thus rendering my computer totally useless. The only thing I could do was reboot, then log into recovery mode, find aptitude and delete the crap. I will never really trust debian again :( -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Opposite of attenuation

by Wolfgang Woehl

Struggling for the proper language: What's the opposite of the term "attenuation" in signal level context? Is it "amplification"? Context is a tool which will output info on Dolby's Cinema Sound processors (CP650/750). Those have a "main fader knob" which will attenuate or, well, amplify the input signal: range 0.0 (-90 dB) to 10.0 (+10 dB), 2 linear parts with a joining knee at 4.0 (-10 dB). Thanks, Wolfgang

Fwd: GMANE and complex networks

by Renato Fabbri

Dear LAU, ::: ---------- Forwarded message ---------- From: Renato Fabbri <renato.fabbri(a)gmail.com> Date: 2013/12/20 Subject: GMANE and complex networks To: linux-audio-dev(a)lists.linuxaudio.org Dear LAD, In studying complex network (a doctorate research), I got into interaction networks because of its utility for understanding social systems. This lead me to GMANE database: gmane.org in which LAD, LAU, LAA (i think), and about 20 thousand other lists are hosted as public and with data available via RSS. After experimentations with some lists, in writing results in an article format, I chose 4 lists: the GNU C++ stdlib development list (official perhaps), LAU, LAD and Metareciclagem, a gadget-media-activist list from Brazil. This article was sent to arXiv: arxiv.org/abs/1310.7769 and is currently being revised by authors, with latest version here: http://sourceforge.net/p/labmacambira/fimDoMundo/ci/master/tree/textos/evol… Some visualizations of these networks in evolution are in: http://www.youtube.com/watch?v=-t5jxQ8cKxM&list=PLf_EtaMqu3jU-1j4jiIUiyMqyV… and: http://hera.ethymos.com.br:1080/redes/python/autoRede/escolheRedes.php Among all options available for doing this research, I chose LAD and LAU with esteem. This lists were quite helpful to me in many occasions, specially in the period 2005-2009. Anyway, this raises a question about this kind of analysis, if it is desirable, invasive in public lists/data. As they are publicly accessible, users should have access also to what kind of information one is able to extract from such data? Or should it be restricted to enterprises, government parties and individuals not sharing about it? I number participants, so names don't appear on results and even in the process of data mining, but should that be? Should that hold for public data? Of course, this discussion might make sense only when there are no aggressive intents, such as developing interfaces to expose someone, which is probably not cool in any case.

A2J-MIDI Bridge error

by Kevin Utter

Hi all! I'm still having XRUN difficulties when recording using MIDI input to a softsynth. Along with the "*** Alsa XRUN" error message, I also consistently get this message from a2j-midid: [31mERROR: [0ma2j_process_incoming: threw away MIDI event - not reserved at time 13248047 Can anyone explain what this error means? I was advised that A2J-MIDI-Bridge might be better than using Jack's seq mode, and it seems to work fine as long as I'm not recording audio at the same time. I may be incorrectly suspecting A2J, but thought it might be worth asking about. Thanks much. Kevin

RFI: Audio Technology magazine 100'th issue

by Patrick Shirkey

Hi, Audio Technology Magazine, issue 99, is requesting input as to: "What pieces of audio gear have come out in the last 16 years that have changed the way the game is played?" for their 100th issue. I'm not 100% on this but I'm pretty sure Linux has changed the game pretty significantly when it comes to running all the game changing audio gear. Inputs should be sent to: mark(a)audiotechnology.com.au - Just saying... Whatever. - Yo Momma, is sooo fat, her gravity causes tidal movement. -- Patrick Shirkey Boost Hardware Ltd

Focusrite 2i2 and LAU

by James Stone

Hi! I seem to have been booted off this mailing list sometime in October.. Not sure why. Anyway, I have a Focusrite 2i4 and hit some major problems with a kernel bug, which I think is the same problem you are reporting. See: https://bugs.launchpad.net/ubuntu/+source/linux-lowlatency/+bug/1185563 and https://bugs.launchpad.net/ubuntu/+source/linux-lowlatency/+bug/1185563 The problems have now been fixed upstream. Seems to work OK on 3.11.0-14-lowlatency. Can't remember exactly which release fixed it tho. James
