[linux-audio-dev] [ANN] No More Specimen

by Pete Bessman

Ladies and Gents, I can hack specimen while working full time. And, I can hack specimen while studying full time. But, and this is empirically verifiable, I can't hack specimen while both working and studying full time. And my situation is not likely to change for another year or so. What this means is that I'm just not cut out to run a project right now, unless I want to put it into maintenance mode. Really, that's where specimen has been for the past six months anyway, and I've been doing a rather piss poor job at that modest role! My efforts are better applied to tasks where smaller chunks of time can go a greater distance. I don't have any regrets --- this was my first real programming project, and I learned a lot. But the truth is that LMMS is more specimen than specimen right now, and it has an active development and user community surrounding it. Plus, I've always been a musician and an artist first, and a programmer second. All told, it's time to throw in the towel on this one. In a way, this is a bummer --- I've put a lot of sweat and tears (literally) into this project over the past couple of years, and it has come an incredible distance. But I'd be a fool to think that I'm better off keeping it afloat than making music and contributing to other projects. And truthfully, it's a huge relief to get this announcement out. A sense of obligation is what kept me from making it sooner, but in retrospect, that's pretty ridiculous. Considering that I'm an "open source, just for fun" guy, and not a "free software, as in freedom" type, it doesn't make a lot of sense to keep going when pain exceeds pleasure. This isn't the end of my open source music development, however. I hope to help take LMMS to the next level, and contribute to other projects that will help make Linux a competitor in the music industry. Things like ardour2, lash, jack-midi, vst, dssi, ladspa et al are the keys to our future in this regard. And I look forward to getting back to hardcore hacking in a few years, when I've got my life settled down and I'm not putting in 80 hours of work and school a week. Take care everybody, and may the funk be with you. -- Pete Bessman http://gazuga.net "So this baby seal walks into a club."

Thank you all for you replies so far. Waiting for more ;) Need some time to analyse all info, but now some quick answers.

It turns out we have to drop UK and Chezh since they are out of Schengen zone and need separate visas. Switzerland is not an option by the same reason. Still trying to figure out the easiest way to get visa. The country we get Schengen visa from should be the first country of our trip. Hope it will be Finland. But it may be France. Fons, thanks for your advice. Replaced Brussels with Antwerp. :) I hope we'll get there. Carotinho <carotinobg(a)yahoo.it> wrote: > Ehi, what's the "?" after Milan?:) Sorry, I know each country is very interesting and beautiful and needs a separate visit. But we want to get the "taste of europe" and look for places we'll want to study deeper. Kind regards, Dmitry.

[linux-audio-dev] jack and sampling rates

by Ken Schutte

Hi, I've recently began trying to write a jack-enabled audio app, and have what's maybe a basic question... From what I can tell, jack has a single global sampling rate, and all clients are required to send and recieve at this rate. Is this correct? If so, are there standard tools/libs to do on-the-fly resampling? I'd like to have a client get a downsampled signal without having to implement my own anti-aliasing filter inside it. Even if there's not something to do the resampling for me, it would be neat if one client could do resampling and others that want the data could connect and get it... is it possible? thanks, Ken

[linux-audio-dev] [OT] First trip to Europe

by Dmitry Baikov

Hello, all! Me and my girlfriend are planning a trip to Europe for a month between May and June. It will be our first trip abroad, so please help if you can with a good advice. Since it's not so easy to get out of here (russia), and I can't visit all that great & numerous openlab's etc., one of the main goals is "community building": I'd like to meet (at least some of ) you, LADs/LAUs, in person. Current plan is (yes, it's huge): Moscow St.Petersurg -- Helsinki Stockholm Berlin Koeln Brussels London Paris Bourdeaux Madrid Barcelona,Figeras Genova Milan? Rome Venice Vienna Prague -- Moscow There are two main questions (lonelyplanet.com helps a bit, but residents can say much more): 1) what is the cheapest way to travel inside europe? Bus? Airplane? If it's by air, how can we buy cheapest tickets? Which company? How much days before the flight? etc. Or may be hitchhiking? 2) how hard is to find cheap place to sleep? AND Where can we meet YOU? Sorry, we don't know exact dates as we are researching on european visa (trip begins from Helsinki, since it seems the easiest way to get into europe). Sincerely, Dmitry.

[linux-audio-dev] Kaiku..ku..kuu.kuuu...

by Juhana Sadeharju

Kaiku. It is unfinished. I'm stuck. A lot of help needed! Don't use seriously. Not all important controls are in GUI. http://www.funet.fi/~kouhia/kaiku20060418.tar.gz Kaiku is now GVerb plus multitap, but will improve to different structure which I have already designed. I will complete the reverb code if the problems will be fixed. (1) Need better GUI. Control envelopes on time-axis for a few features. GTK2 and/or OpenGL. We discussed about the great amount of callbacks used in my GTK code years ago but I did learn nothing ;-) (2) Preset system. XML files. (3) How to run a Jack application in an editor as a non-realtime plugin? (4) Kaiku should start as unconnected Jack application. Or connected to Alsa or Jack ports given as command line options. (5) My computer is only barely running Kaiku in realtime, and that after I reduced the multitap delay complexity. I have not taken speed-ups from LADSPA-GVerb. Uh oh. The code has unused old code as well. Some experimental GUI stuff. Ignore them. I only would like to have a Lexicon quality reverb. Designing and coding such a reverb is a huge task, and it won't help if I spend years with basic software engineering tasks which any Joe programmer could complete easily. My private Lexiclone has several algorithms of which only GVerb has been turned to open source within four years. I'm not a reverb designer or DSP engineer either, and I'm not sure do I want be one. I started figuring out the reverb business with zero DSP knowledge, and only because we did not have a quality reverb -- I wanted to change the situation. Could we collect $$$$$ of money and hire Dattorro or any other qualified effect guru to design quality open source effects for us? Blender was purchased for $100,000, right?

[linux-audio-dev] Patch storage for simple DSSI plugins?

by Gordonjcp

What's the consensus? Implement patch storage for plugins that don't really have that many controls, or just let the host worry about it? Gordon.

[linux-audio-dev] [ANN] netjack-0.11

by torbenh＠gmx.de

netjack-0.11 ------------ Warp your jack ports over an IP network. Also have Transport synced between 2 machines. Work is underway in improving the latency for big channel counts, like 24in / 24out. There seems to be a bottleneck in the kernels handling of big UDP Packets. However netjack seems solid with a period size of 128 and a roundtrip latency of 3 periods. (this is at 24/24 float on 100Mbit) The latency does not seem to improve with Gbit. Also featuring: - improved error messages. - some AutoConfig on the slave side. (only period and samplerate) - alsa_in and _out improvements. Have Fun. -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language
