Hello. Would anyone have Csound mailing list archives posted before Feb 1997? I could not find them from Dream at UK. Has anyone archived them privately and could give them to me? Anyone on Csound list could request them for me? Best regards, Juhana

[linux-audio-dev] [ANN] Version 0.3.2 of liblrdf

by Steve Harris

Doesn't add any features, but builds with raptor 1.0.0 and removes a dependency on the LADSPA SDK. Now requires raptor 0.9.11+ and pkg-config http://plugin.org.uk/lrdf/liblrdf-0.3.2.tar.gz liblrdf is a library for handling RDF desciptions of plugins. It allows them to be categorised and thier metadata to be queried without loading the .so files. RDF is a W3C standard for metadata: http://www.w3.org/RDF/ A categorisation of the CMT library is available: http://plugin.org.uk/lrdf/cmt.rdf And swh-plugins comes with an RDF description of itsself. - Steve

by benno＠gardena.net

I think we should invite all journalists of keyboards, recording and audio magazines to the next LAD meeting at ZKM 2004 http://www.linuxdj.com/audio/lad/eventszkm2004.php3 Thi should make some of the disinformation that is currently spread by these magazines going away.

[linux-audio-dev] capturing code

by Ghaith Nasrawi

hello there, we are writing here a software that requires capturing code to stream live voice from one machine and play it on the another machine through a network. can anybody enlighten us for a library or a method we can use to capture the voice and stream it on the /dev/dsp?? as soon as we get this working, we will go through some advanced stuff, and we will be sharing this with you later. thanks and regards. -- (o_ //\ Ghaith Nasrawi V_/_ The American University in Cairo "In all matters of opinion, our adversaries are insane."

[linux-audio-dev] KEYBOARDS: Linux is not suited for audio applications ...

by Uwe Koloska

Hello, the german magazine KEYBOARDS has answered a readers question about audio and linux with tremendous ignorance. I think this is a good chance to push linux to the attention of "the masses". Here is the full text of question and answer (first in german, so anyone can correct my errors ;-). --- KEYBOARDS -------------------------------------------------- Leserbrief: Habe mir schon ein paar Mal KEYBOARDS am Kiosk geholt, weil mich gerade das Thema Recording und Computer interessiert. Einige Artikel waren für mich recht interessant. Nur vermisse ich gänzlich Vergleiche mit Linux. Ist es Absicht, dass dieses aufsteigende System nicht erwähnt wird, oder traut sich keiner ran? Seit einigen Monaten steige ich auf Linux um, nur meine Musik-Geschichte hängt hinterher. Dabei gibt es in SuSE eine Menge Musik-Software und Synthesizer, und ich habe gelesen, dass einige Programme bald zur Marktreife gelangen. Von Verkäufern höre ich, dass sie nicht am Linux interessiert seien, weil man da nix mehr verdiene. Von anderen höre ich, Linux sei kein Multimedia-System. Desinformation auf der ganzen Linie ... Rainer Hain (KEYBOARDS): Das Ganze ist ein recht kompliziertes Thema. Linus Thorvald selbst hält Linux nicht für Audio oder generell für Multimedia-Anwendungen geeignet. Low-Latency ist mit den aktuellen Kerneln schlicht nicht zu machen, schon gar nicht Multichannel. Dazu kommt dann, dass ein Setup von Linux heute zwar simpel ist, aber nur, solange man nicht von einem Standard-SuSE abweicht. Und das muss man, wenn man Audio und MIDI betreiben will. Deshalb springt kaum ein Sequenzer-Hersteller drau an, die fürchten den ungeheuren Support-Aufwand. (Man erkläre dem User mal am Telefon, dass er ein Make-File ändern muß und wie er dann die Sources neu kompiliert ...) Deshalb gibt es auch kein Package, was auch nur entfernt an Cubase oder Logik herankäme. An der Treiberunterstützung hapert es halt auch. Ich habe hier zwar eine gute Auswahl an gängigen Interfaces (Audio und MIDI), aber für keines davon gibt es Linux-Treiber. --- english translation ---------------------------------------- Reader: Sometimes I have bought Keyboards cause I'm especially interested recording and computer. Some articles seemed to me very interesting. But I deeply missed any comparisons with linux. Is it intended that this rising system is not mentioned or does noone felt able to do it? Since some month I'm migrating to linux -- only my musical things are left behind. Despite SuSE having a lot of music software and synthesizers; and I read about some programs coming to end-user stability soon. From dealers I hear, that they are not interested in linux cause there is nothing to earn. Other people say, linux is not a multimedia system. Desinformation all along the line. Rainer Hain (Keyboards): This is a very complex matter. Linus Thorvald himself considers linux not to be suited for audio or universally multimedia applications. Low-latency cannot be achieved with current kernels especially not multi-channel. On top of that comes the fact, that a setup of linux is quite simple today, but only if you don't leave the standard SuSE. But this must be done to work with audio and midi. Therefore hardly any sequencer manufacturer uses linux -- they fear the tremendous support effort. (try to explain a user on the phone, that he has to change a makefile and how he must compile the sources ...) Therefore there is no package that can hardly reach the level of Cubase or Logic. The driver support also is a problem. I have a great variety of popular interfaces (audio and midi) but there is no linux driver for one of them. ---------------------------------------------------------------- I hope we are able to shape a convincing answer!

[linux-audio-dev] European software patents?

by Juhana Sadeharju

Hello. I picked the text below from xine-devel, but I picked it too late. If this topic has been discussed here, I have missed the thing. If Europe gets the software patents, I'm willing to archive any withdrawn software to our archive site ftp.funet.fi. There they may wait another 20 years for reappearence. What to do if Europe gets the software patents and your software is requested to be taken away from public? How far one should go in order to get the case officially reported? At least, one should not take anything away upon an e-mail request as then nothing is officially reported. It is important to get the cases reported each time so that the cases can be analysed later by the researchers. Juhana [ someone wrote in xine-devel ] >The European Parliament will debate and probably decide on a proposal >for a software patent directive on September 1st. If this directive is >passed, things like algorithms and business methods such as Amazon >One Click Shopping will become patentable in the European Union just >like they already are in the United States. > >Read more about the issue here: http://swpat.ffii.org/index.en.html

[linux-audio-dev] Wrote a real time safe memory allocator in C++

by Benno Senoner

Hi, I wrote a simple but very efficient real time safe memory allocator in C++ that is useful in real time audio apps where you need to allocate objects dynamically. (badly enough there are still too many audio developers that call new,delete, malloc() and free() within the audio RT thread !) It works by pre-allocating a fixed pool of elements which can then dynamically allocated and freed. The alloc() and free() have fixed execution times and are inlined thus if you look at the resulting assembly code it takes only 8-9 instruction for full allocation/deallocation. It has the limitation that the pool contain elements of the same datatype/size. Each element is a node of a doubly linked list (the free-list) so keep in mind that if you create a pool of N elements with s=sizeof(your_datatype). The total memory usage is (N+2)*(s+8). So it is not ideal to create large memory pools of chars (1 byte) because for each char you would need 1+8 bytes of mem. But for larger data structures it is ok. creation of the memory pool: RTMemoryPool *mypool=RTMemoryPool<your_datatype>(number_of_elements); allocation of a element: my_datatype *element=mypool->alloc(); freeing of an element: mypool->free(element); destruction of the memorypool: (frees up all the memory): delete mypool; Using the RTMemoryPool class requires only the inclusion of the rtmemorypool.h header file, no .cpp files required. You can download the RT memory allocator (which contains an small example that user the class) here: http://www.linuxdesktop.it/download/rtallocator-0.0.2.tgz if you find bugs or have suggestions let me know. (write to benno@ and not sbenno@ because I do not read that mailbox, too much spam). cheers, Benno ------------------------------------------------- This mail sent through http://www.gardena.net

[linux-audio-dev] question about cue sheet apps

by Dave Phillips

Greetings: While profiling FLAC I discovered that the format includes a metadata format for including cue sheet data for use in CD mastering applications. When I looked for a Linux-based cue sheet editor I found only the very outdated CDB (CD Builder), which, true to its author's advice, will not build under GTK 1.2 or 2.x. I thought perhaps JAM would concern itself with cue sheet data but I think that's not its domain (the FLAC docs note that the cue sheet data is intended for CD authoring apps). Btw, I downloaded and tried running some Windows-based cue sheet editors under WINE, with varying success, but none were completely useful. Maybe I should update my WINE installation again, but I'd prefer a Linux-based solution anyway. Sorry for the cross-post, I thought perhaps someone on LAD might be developing such a creature (?). Do any users on LAU utilize a cue sheet editor for any of their work ? Best regards, == dp
