[linux-audio-dev] The Linux Audio Vision

by Carlo Capocasa

Hi, all! Contact me at: theman-AT-carlocapocasa.com As you might know I am a full time linux audio musician, and in the process of forming a company to produce music with linux audio exclusively and release it licensed CreativeCommons Attribution ShareAlike in OGG Vorbis format exclusively. (With the option to keep up with whatever standard the Free Community agrees on) I had one of my first sessions with Carlo, my partner today, and there is no doubt on my mind we will be very well received by a LOT of people. Lyrics are along the lines of the practical new age movement, which focuses on achieving goals using the mind as a primary tool. My goal is to create a company, that is a little bit different than other companies in that it has a broader definition of profit motive. The primary profit motive is satisfaction, while it is trusted that money will find itself a way to follow as well. Currently, this means specifically to simply sell some products on a musician's web site that has a lot of traffic because word of mouth draws people who want to download free music there. Contact me at: theman-AT-carlocapocasa.com To make linux audio more attractive, I am looking for developers to partner with me in building a "Just Works" device one can plug in the wall, and hear the latest and greatest of the Free Audio community. Ideally, the device would simply have an 'I Like It' button that would Cache whatever song is playing and direct the listener's preference profile toward similar songs. I would like to see this device be engineered using 'Free Engineering' principles, along the line of the Free Software community, being "funded" entirely by donated work efforts, all the way to the assembly line. This is an ambitious project, but I'm an ambitious kind of guy, and so our you when you let yourself be. I find it completely irrelevant what experience you have had in this field so far, as long as you feel a deep urge in yourself to be part of this project. Please contact me, right now! It doesn't matter if you don't know yet what exactly your participating what form it may take. Just contact me if you resonate with this idea and would be willing to donate a LOT of your time for this, for the reward of satisfaction, and probably some quite physical rewards as well; however these will be left to take care of themselves, which I trust they will. Contact me at: theman-AT-carlocapocasa.com I am also looking for developers who would like to fine-tune and even out current linux software synthesizers to make them completely rock-solid for live use, so anyone can use them to play a gig with 10'000 people without thinking once that there might be dropouts. Of course number of possible voices is limited by processing speed, however CPU cycles need to be managed in such a way that limitations in processing power are reported and can be dealt with off-stage. Most specifically, I am talking about ZynAddSubFX, and to some extent Om/Ingen. Another area that needs development power is transparency; ZynAddSubFX is a fantastic sounding synth, however its interface can be cumbersome for some purposes, specifically automation. Additionally, these sounds should be accessible in a standard way, without requiring but optionally enabling MIDI. The best way to accomplish these goals would be to create a ZynAddSubFX DSSI plugin with a complete redesign of the interface; in addition, a set of LADSPA plugins for use in modular synths would be excessively helpful. Again, it doesn't matter if you have development experience, it is plenty if you have the will and the dedication to invest your time and energy. I will work closely with you and your reward will be that YOU were the guy who made it possible for tens of thousands of people, heck, millions of people to enjoy the sound of the Free Software synthesizers played live and in realtime in the most advanced way possible. Contact me. Contact me at: theman-AT-carlocapocasa.com The company is not really a company in the conventional sense, just people working together on a common goal. There will be no central authority and no orders; just suggestions and mutual service. There will be no guaranteed rewards, however there is deep satisfaction that this project will be the only way for you to attain, you being the right person for this project. It will be your key to salvation if you will, your holy grail, your life's mantra. Devoting yourself fully to it you will open the possibility for "All the ways you haven't thought of yet" to come together and make it possible for you to continue living. And I'm not talking about just any living, I'm talking about living in TREMENDOUS WEALTH. Again, you will probably not receive your "rewards" directly in the form of a bribe, and you will certainly not be lead around by the nose with petty rewards. You will do what you do to accomplish your goals that satisfy you, and you will learn how to do that. Simultaneously, you will learn from me how to attract into your life whatever (material or not) you need to enjoy your life more, and how to open your channels for good to "happen to you". (Yes, money cars and women can "Happen To You", I will be more than happy to explain exactly how that works to you, all you need to do is ask.) So I'm looking for passionate software developers and engineers! Please contact me. Contact me at: theman-AT-carlocapocasa.com We will change how the world works. Money is a wonderful thing, if you don't let it dictate what you do and what you don't do. You can simply use it like you would use other shiny things, as a token of appreciation. You can also use it to encourage services where there would otherwise be ambivalence. Money is a good thing! And money definitely does not have to be a reason to do anything else than what YOU are passionate about; and this, as parts of the free software community, we will demonstrate to the world in undeniable clarity. Have any of you noticed how sleek and, in short, how amazingly good the Mozilla browser is? I mean three platforms, and this software quality, that is nothing short of a miracle. Linux Audio can be that way too! We just need to get a little more organized, and I will be more than happy to serve as a usability expert, since I'm a guy who uses the software professionally and I have the technical skills to communicate what needs to be changed and what most realistically can be changed (while still keep a "No Limits" attitude. Contact me at: theman-AT-carlocapocasa.com Join me! Help me create good free software AND free hardware. You don't need to know how, and I don't need to know how. Faith and action will take care of the rest. Whatever techniques you will need to accomplish these goals will come to you as soon as you have made a definitive decision to accomplish them. All you need do is decide that it WILL happen and never think back. The free hardware is so sexy you would hardly believe it. Think of it! We can be giving away "music boxes" that are constantly loaded with the latest in the free music community, according to the listener's preferences, which he can communicate with a big red button. Lit with a high-powered LED. Man this is so sexy I almost have to change my underwear after even thinking about this. Join me, guys! Contact me at: theman-AT-carlocapocasa.com Carlo

[linux-audio-dev] [admin] new linux-audio-* maintainer wanted...

by Joern Nettingsmeier

hi everyone! over the last couple of months, i have not been able to tend to the lists very much - moderation latency on laa was sometimes as high as 5 days while i was on tour... sorry for that. since my workload is not likely to go down in the future, and since i have unfortunately lost some touch with the linux audio community (i haven't actually read the lists very much lately, as my main occupations were live audio and [YUCK!] web development), i'd like to pass on the baton of the list maintainer. a few months ago, some people have already volunteered - please drop me a mail again, i may have lost the old ones. if you think about taking on the job: we have 3 lists, linux-audio-[dev|user|announce], all run by mailman on a darwin server at columbia university, new york. you can have shell access on that box for admin tasks, and there is a neat web interface for common admin jobs. basic understanding of mail-related rfcs is certainly helpful, but i'm not exactly a mail god myself and found the job not too daunting :) some good spam filter will certainly help with the job - the admin addresses are getting spammed so heavily that i can't really process them anymore. please speak up if you're interested. best regards, jörn -- jörn nettingsmeier home://germany/45128 essen/lortzingstr. 11/ http://spunk.dnsalias.org phone://+49/201/491621 if you are a free (as in "free speech") software developer and you happen to be travelling near my home, drop me a line and come round for a free (as in "free beer") beer. :-D

[linux-audio-dev] [ANN] GLASHCtl 0.4.0

by Lars Luthman

This is a simple applet for controlling the LASH Audio Session Handler. When you run it it will appear as a small LASH icon in your "notification area" or "system tray" (if your desktop manager is compatible with freedesktop.org's "System tray" standard, http://www.freedesktop.org/Standards/systemtray-spec). This is typically somewhere in the panel in KDE or GNOME. There is also a front end for the WindowMaker dock (or compatible window managers). Changes since 0.2.0: * A DockApp front end (thanks to Nedko Arnaudov) * A "Recent" submenu for restoring recently saved sessions * A "Connect" submenu for connecting and disconnecting JACK ports * Doubleclicking session directories in the file selection dialog restores the session instead of going into the directory * The message window is removed Get it at http://dino.nongnu.org/glashctl -- Lars Luthman - please encrypt any email sent to me if possible PGP key: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x04C77E2E Fingerprint: FCA7 C790 19B9 322D EB7A E1B3 4371 4650 04C7 7E2E

[linux-audio-dev] Just a question/idea

by Elthariel

Hello, Here is just a simple question about linux audio. I'm looking for some software which doesn't appear to exists. But it should be quite few projects which have not release any code for the moment. So I'm asking the question :) Is there any windows manager that supports jack and lash, in order to make the ''Desktop'' become a modular studio ? Is it possible at least ? If it is, is there anyone here with the time and knowledges to start a project of this kind ? Regards, Elthariel.

After all, we the guys/gals are few and numbered, but do it for the fun and love, not for the money. Bah, did I say "love" ? Ah, for you who that don't know me, I was a hardcore windows developer once before. Ah, read "once" with emphasis :) thing of the first-half-nineties, blerk! Bottom line is, and that's not an opinion, the F/OSS (r)evolution is already unstoppable. Evidence comes to that IBM knows it. Ultimately, MS knows it too. And you just got to face it now? If you stay with me, and I believe MS strategy cannot be far behind, the OS business is already a dead-end. People are in charge. If you speak BS-like, you can read: the customer is in charge. And don't reply that was RH who come original with that slogan. I do remember something of the sort from Hammer's "reengineering the corporation". Yes early nineties gone old :) Just for the topic, funny thing is, a copy of gamma's/GOF is still around here somewhere and being a mid-nineties foundation truth must be told,... I'm just an old donkey who doesn't learn new languages anymore :D Cheers. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

Re: [linux-audio-dev]Multiplexing 4 channels on SPDIF

by mikko.helin＠luukku.com

Just wondering how the framing is specified in that protocol, does it use some lsb's just like the VST System Link protocol does? It would be also nice if you documented the protocol and made it PD so the support could be added also to ASIO4ALL drivers etc. (http://www.asio4all.com/). Btw. In theory you could support 8 x 24-bit (less the framing bit) / 48kHz audio transfer over the SPDIF if you used the 192 kHz sampling rate! Not bad, where do we need the ADAT protocol actually? - Mikko ................................................................... Luukku Plus paketilla pääset eroon tila- ja turvallisuusongelmista.

[linux-audio-dev] [ANN] kbdz 0.2.0a

by Elthariel

I'm happy to announce the release of kbdz 0.2.0 alpha, a set of tool which allows you to transform classical pc keyboards and mouses plugged via USB into midi keyboards and controller. Support for joysticks is planned for soon. It uses alsa sequencer and the 'new' event devices stack (evdev module). You can find it here: http://sourceforge.net/projects/nahlwe/ Please give me feedback if you test it. Regards, Elthariel.

What we can do ? Are our alsa results due to misconfigurations ? > Only the oss modules in the linux kernel are deprecated. Programs using the OSS api will still continue to work, currently most importantly because of the oss emulation module in alsa. If you should choose between alsa and oss, and the oss version works just as well, or better than the alsa version, choose oss, because its a more portable API than alsa. However, if I were you, I would use sndlib, portaudio, jack, or some other higher level audio input/output library instead of oss or alsa.
