Re: [linux-audio-dev] plugin GUIs .. Mediastation, LADSPA ?

by Juhana Sadeharju

>From: Benno Senoner <sbenno(a)gardena.net> > >the method I use to communicate between the GUIs is SYSV message queues >because they can be multiclient but the API is abstracted so the >underlying transport model can be chosen arbitrarily. I have written and I'm writing a message system where client sends, e.g., the following msg to the server: read <file id> <loc> <len> <addr> <return value> which reads a block of audio from a file to a (shared) memory location. I did not see the return value in your system (and don't figure out how one goes without it). The server sends both the result and the given return value back to the client. The return value could be something which only the client knows, e.g., array index, memory address, text. Something which associates the result with the request. The implementation is too complex to my taste as the messages are combination of raw byte data and string data. Each message starts with <int> which tells the length of the message. I have written a set of routines to assemble and disassemble these messages. I send these messages via pipes/sockets, via shared memory, and whatever. In any case, such message system should be general enough, and the return value brings it to that direction. Hmm... what do you mean by multiclient? Is the writing to the message queue an "atomic" operation for long messages? I use one pipe/socket per client to one server because I suspect only the server can make the long messages "atomic" by interleaving them correctly. Likewise, I use one lock-free shared-memory FIFO per client to one server. Regards, Juhana

[linux-audio-dev] Retro speech synthesis

by David Olofson

Inspired by the Vocaloid thread, an old idea sprung back to mind; retro "chip style" speech synthesis. Is there a simple, minimalistic, Free/Open Source phoneme-to-audio synthesiser out there? I'm not terribly interested in the text-to-phonemes part and other higher level stuff, as I intend to use this for sound effects in games and (other) toys. Doesn't hurt if CPU and memory requirements are very low, but I'm probably going to render words and phrases off-line anyway (at install or load time), for later processing as normal sound effects. //David Olofson - Programmer, Composer, Open Source Advocate .- Audiality -----------------------------------------------. | Free/Open Source audio engine for games and multimedia. | | MIDI, modular synthesis, real time effects, scripting,... | `-----------------------------------> http://audiality.org -' --- http://olofson.net --- http://www.reologica.se ---

Re: [linux-audio-dev] virtual vocalist - I think we could have something similar without much work...

It could probably not be very hard to write a similar GUI where you edit a pianoroll to make festival sing. Seems like a very nice small project, anyone willing to take it? Juan Linietsky

[linux-audio-dev] spiral modular synth problem [libGL.so woes]

by Florian Schmidt

Hi, i tried to build the spiral modular synth [it's the same problem for cvs and release]. Builing works fine, but running afterwards throws out a bunch of error when trying to load the plugins. The errors are all similar to this one: WARNING: File /usr/local//lib/SpiralPlugins/MoogFilterPlugin.so could not be examined dlerror() output: libGL.so.1: cannot handle TLS data Ok, i see that me running the nvidia binary only drivers could have something to do with it, but i wonder why the plugions get linked agains libGL.so anyways.. Here's a link line from the build procedure: g++ -shared -o JackPlugin.so JackPlugin.o JackPluginGUI.o ../SpiralPlugin.o ../SpiralPluginGUI.o ../../ChannelHandler.o ../../Sample.o ../../RiffWav.o ../Widgets/Fl_Knob.o ../Widgets/Fl_LED_Button.o ../../../GUI/Widgets/SpiralGUI.o -L/usr/X11R6/lib -L/usr/local/lib/ -L/usr/X11R6/lib -lfltk -lXft -lpthread -lm -lXext -lX11 -lstdc++ -lGL -lXext -lX11 -ldl -lrt -ljack -lpthread I suppose it get's this flag from some library or something but i didn't suceed in finding out from where... Anyone can shed light on this issue? Flo -- music: http://www.soundclick.com/bands/9/florianschmidt.htm

[linux-audio-dev] ANN: RTMix 0.75 released

by Ivica Bukvic

Greetings! It's my pleasure to announce immediate availability of RTMix version 0.75. RTMix is an interactive multimedia art performance, composition, and coaching interface capable of triggering various DSP applications and/or processes concurrently, as well as offering a tight coordination between computer(s) and live performers. It can also trigger real-time events utilizing MIDI and OSC protocols, and can be in theory networked from a single client with up to 1000 other RTMix clients (personally neither have I had the opportunity to try this and besides the network latency would probably get the best of it anyways). For more info on what it is, what it does, and how it does it, please see the online docs: http://meowing.ccm.uc.edu/~ico/RTMix-doc/ Changelog: *Minor bug fixes in scripting language. *Ability to connect directly to /dev/sequencer (needs to be tested -- any help in bug reporting is greatly appreciated!). This should theoretically enable users to have theoretically infinite number of MIDI devices hooked up to RTMix (using ALSA's aconnect). *UI improvements (mostly "eye-candy"). *New LED icons for improved visibility. *Improved functionality of the Console. *Full documentation included in the distribution (just in case someone missed this one from before :-). *New application icons (16x16 to 192x192). *Smaller tarball. *This is the last version before the milestone 0.8 release with that will sport a completely revamped UI and many new features. RTMix has so far been featured at ICMC 2002 conference (Sweden), SEAMUS 2003 conference (US), in the "Organised Sound" magazine (December 2002), and has been used in several of my works whose recordings are available on my website. If you happened to use RTMix in your work, I would love to hear in what ways you got to utilize its features, as well as how can I make the application better. Thanks! The tarball is available for immediate download from: http://meowing.ccm.uc.edu/~ico/rtmix-latest.tar.gz (4.07MB) For more info, please visit my website and/or the online documentation (provided above). Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico
