[linux-audio-dev] Travel to lad-conf

by Julien Claassen

Hi folks! I'm looking for someone to accompany me to Karlsruhe by train. I'm coming from Paderborn. But I will go through Dortmund, essen, duisburg, Koeln. To those places I can get on my own, from there I need help. For those of you who don't know it: I'm blind. So I get a free companion. That menas half the price. I want to go there on wednesday and leave on sunday. On wednesday Joern can come with me, but the way back is unsure yet. If anyone goes that way: just tell me...

[linux-audio-dev] Re: Linux soundapps pages updated

>From: Jens M Andreasen <jens.andreasen(a)chello.se> > >Dave is not doing his site for a living and when introducing updates, he >just picks what appears to be "the essence" or "the catchline" in the >releasenotes. Yep, it is very hard to keep the list up-to-date if developers theirself don't write the entries and update them. Most software I have downloaded won't even compile and documentation is not always adequate. That is why I selected for my list a format which encourages users to find out what software among several candidates fits for them. The list is attached below. I also have a similar list for graphics software. I have not checked Dave's list at all in making my list. I actually have downloaded all the software. And I still have 15 Gbytes of downloaded stuff unchecked and 300+ urls to go through. I have included a list of unsorted items at the very end. I'm also downloading material for making similar lists for commercial software and hardware. Manuals, screenshots, SDKs -- whatever could be useful for us.

[linux-audio-dev] FreeVSTi Compatibility List / VSTserver & FST

by Christian Frisson

I'm far from being a developper (a kind of LAU member lost over there...) therefore I've tried several attempts to contribute in my way. The last in date is managing to test all the FreeVSTi plugins listed on the K-v-R database, reaching approx. 200, with VSTserver / vsti. As there's some work left, after two or three fulltime days of labour, I was waiting to put the whole on a thread on the K-v-R Forum, what I'll do as soon as possible (all plugins are waiting, sorted on my VST_PATH), but the last messages here force me to reveal some personal conclusions. First of all, some relevant testing data: - System-wide: "2.4.24-1.ll.rhfc1.ccrma kernel" on a 2.4 GHz PIV, ALSA 1.0.1-1.cvs on an "ice1712" card, - Sound-wise: jack-audio-connection-kit-0.94.0-1, wine-vstserver-0.3.0, vstserver-0.3.1, vsti-0.0.3 The plugins integration seems to be convenient to categorization tags, sorted as follows: - Fully-working, - Removable stuck notes (i.e. stuck notes able to be removed when re-triggered: bound to monophonic synth use), - Jack zombifier (sometimes needing a jack-restart, else a reboot, as I can't kill Jack properly), - Invisible (no errors emitted, connections existing under Jack, but the GUI doesn't appear), - "10s'" (Plugin "*.dll" used more than 10 seconds in the process-thread. Killed it.), - Non-working, - System-freezing, (I won't paste here the respective error logs.) Most fall into the first two categories, hopefully, even though reverse-ordered in quantity. My first comments upon some weaknesses (bearing in mind it's a bit easy-speaking - not intending to flame): - Multiple instances can't be launched, as opposed to the library state of FST, - FST's lack of server separately launched seems more ergonomic to users like me. Should the server natively built in Jack? Or should we be able to use a graphical app like Steinberg Cubase's "VST Instruments"? - VSTserver can't launch plugins from separate folders, can it? Or could this be achieved by putting another set of "vstserver" & "servant" in each of them then? All of the above are mainly due to the beta state of the collection of apps, what I'm aware of. - I'm used to changing directory to $VST_PATH in order to benefit from the tab completion when launching plugins with "vsti". Why not having called it "VST"? Shorter to type... - When it comes to preventing from crashes due to user-failure, VSTserver then Jack do not appreciate partial filename launched with "vsti", like *.d (the closest tab completion before *.dll & *.dat files, for SynthEdit plugins). Dots aren't either appreciated. A need of implementing extension check after the last dot? The aforementionned Graphic VSTi launcher would enable avoiding such wrong filenames entered by the user. What about the coexistence of VSTserver and FST on a same machine? Hard times for the moment, as long as VSTserver uses a custom-tuned version of Wine and FST the newest possible... No free-babbling here, all of this just leads me to end up with a good question: as many libre-projects are often started with the same objectives, will we benefit from a collaboration between VSTserver and FST? Cheers, Christian Frisson

I've just released BruteFIR 1.0 www.ludd.luth.se/~torger/brutefir.html It is a high performance generic multi-channel audio convolver, compatible with ALSA, OSS and JACK. Apart from the OSS I/O module, there is not much new compared to the the previous 0.99n release. Just some boring compile/portability error fixes and stuff. /Anders Torger

[linux-audio-dev] Weird xruns in via82xx+ 2.6.x kernels/ via82xx+jackd/ and what is dxs_support

by ico＠fuse.net

Hi all! (I posted this a while ago using a different account but it never went through so here it is again :-) Two questions: 1) when using via82xx driver the sound using aplay sounds choppy, faster than usual, and has xruns (???) even when using a simple aplay command on a wavefile. syslog suggests using something called dxs_support=1 or 4 but even if I put this into my /etc/modules.conf it still does nothing and syslog continues to suggest the same thing. Does anyone know where am I supposed to put this statement in order for it to work? Please be as verbose as possible. Thanks! The sound sounds fine when using "play" though and there are no xruns. 2) when trying to use jackd and via82xx as a regular user it always starts up does not report any errors but qjackctl complains that it could not connect to the jack and when starting it on command prompt it starts without any apparent errors but when trying to connect to it using for instance jack_metro it says "is jack running?" or something similar. Now, when I do the same as a root, it works like a charm. Any ideas why is this? Any help on these issues would be greatly appreciated! Best wishes, Ico

[linux-audio-dev] initial release of libfst - in-process VST support

by Paul Davis

Torben Hohn and I are pleased to release an initial version of libfst, a small GPL'ed C library that provides support for using win32/x86 VST plugins (FX and VST/i) within native Linux applications, with the assistance of the Wine project's libwine. ========================================================== We expect there will be several minor problems with this initial release. Please help us fix them! ========================================================== How is this different from VSTserver? ------------------------------------- This work differs from Kjetil Mattheusen's VSTserver because the plugin is loaded into the address space of the program using the library, not into a server. As a result, it is a more appropriate solution for audio applications that might support many VST plugins, where the context switches required in the VSTserver case do not scale well. The downside, of course, is that a misbehaving plugin will crash the host application, which VSTserver avoids. Why is it called FST? --------------------- In case you wonder, "fst" stands for FreeST. Imagine saying "VST" with an odd lisp. Where do I get it? ------------------ The tarball is available from http://linuxaudiosystems.com/fst/fst-1.5.tar.gz How do I know it works? ----------------------- Ardour and gAlan are already using this technology, and please read my next announcement. Dependencies ------------ The library is very small. You will need a recent version of Wine. The configure step (which uses stuff built by Wine) takes much longer than the compilation. To build the library from source, you will need the Steinberg SDK header files AEffect.h and aeffectx.h. These cannot be redistributed by us or anyone else. The configure script will tell you where to get them. The registration process with Steinberg points you to an FTP URL that does not have the VST SDK on it. Use this instead: ftp://ext2asio:sdk1ext@ftp.pinnaclesys.com/SDK Please do NOT bypass the Steinberg registration process. It is important to show them whatever level of interest the Linux world has in VST. --p

[linux-audio-dev] draft announcment

by Taybin Rutkin

JACK RELEASE 0.98.0 JACK is a low-latency audio server, written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin"). JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation. JACK is available at http://jackit.sf.net ***CHANGES*** Fixed bug when using non-dithered 16bit output. Fixed crashing bug with JACK clients that use SSE. three new functions in JACK API: int jack_client_name_size(void); int jack_port_name_size(void); int jack_port_type_size(void); These sizes are inclusive of the final NULL character. Automatic server startup (more on this below). Added OSS JACK driver. New option -m,--no-mlock: Do not attempt to lock memory, even if --realtime. New option -p,--port-max n: Set the maximum number of ports the JACK server can manage. The default value is 128. New option -T,--temporary: jackd will exit when last client disconnects. Configuration process reworked for better portability. This has helped jack run on MacOSX and FreeBSD. Added JACK thread initialization callback. ***AUTO START SERVER FUNCTIONALITY*** libjack will now try to automatically start jackd when jack_client_new() is called if it isn't already running. Because this changes the semantics of jack_client_new() and confuses certain apps, the new semantics apply if and only if $JACK_START_SERVER is defined and $JACK_NO_START_SERVER is not defined. This will change in future releases. libjack determines the proper arguments to pass to jackd by first checking ~/.jackdrc, failing that /etc/jackd.conf, failing that hardcoded strings that we've determined to be the most likely to work on a variety of platforms. The format of ~/.jackdrc and /etc/jackd.conf is as follows: absolute path to the jackd or jackstart binary to be executed, followed by the regular arguments all on one line. libjack will automatically insert the --temporary argument so that any auto started jack server will exit when the last client has disconnected. If libjack is unable to start the server, jack_client_new() will fail normally. We hope that this new functionality will make using JACK easier and more seamless with the JACK client. Taybin

Should there be 3 seperate irc rooms then? One for each concurrent lecture?
