[linux-audio-dev] RE: ENE Cardbus controller

by Ivica Ico Bukvic

Thank you very much for your help. I guess it does seem there is some weakness in the interface, however I am not convinced that this is the entire story simply because in such case at least playing a single sound via ASIO would work. In my case no matter what I try to play (even if I try to play a single crappy stereo wav sound, it still has the same artifacts like the more demanding setup -- it seems that the amount of throughput does not alter the sound quality or speed. This firewire solution you mentioned, will it work with Multiface, or will it be a separate thing that I'll need to dish out huge amounts of money for? :-( (also if there is any info on it available on the net, any additional info will be utmostly appreciated) Again, thank you very much for your help!

[linux-audio-dev] RE: Major problem with RME HDSP/Multiface and a 64-bit AMD laptop

by Ivica Ico Bukvic

Forgot to ask two more questions: 1) How can I go about testing the throughput of my pcmcia cardbus in order to see whether it is the culprit? 2) If the cardbus proves to be the problem, is there a way to hook-up hdsp directly via Firewire port, or is there perhaps an adaptor that converts either USB 2.0 or Firewire into pcmcia cardbus? Many thanks! Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/

Dyne:bolic GNU/Linux is a live bootable cd, containing a whole operating system working straight from boot, without the need to install or change anything on the hard disk. You can try it out very easily and if you like it you can simply copy a directory on your harddisk and run it locally. Dyne:bolic is user-friendly, recognizes your hardware devices (sound, video, firewire, and USB), and offers a VAST range of free software applications for multimedia production, audio and video streaming, sound composition and synthesis, 3D modeling, photography, peer2peer filesharing, web browsing, desktop publishing, word processing, cd burning, email, encryption, remote conferencing and even more. It also includes many games and a world atlas navigator. It does automatic clustering, joining the CPU power between any other dyne:bolic on the local network. Last but not least: it works on modded XBOX game consoles. Dyne:bolic is shaped on the needs of media activists and artists to stimulate the production and not only the fruition of digital and analog informations. It takes birth as a grassroot effort to spread free software and the spirit of sharing information and knowledge. :: WHAT'S NEW IN THIS RELEASE ?

If you are wondering where this all comes from and why is it free, and where it is going: here is the answer! This software is about Resistance ina babylon world which tries to control and limit the way we communicate and we share informations and knowledge. This software is for all those who cannot afford to have the latest expensive hardware to speak out their words of consciousness and good will. This software has a full range of application for the production and not only the fruition of information, it's a full multimedia studio and has nothing to envy to other proprietary systems, because freedom and share of knowledge are solid principles for evolution and that's where this software comes from. This software is free, Jah Rastafari Livity bless your freedom! You should share this software for the good of yourself and your people, respect others and let them express, be free and let others be free. You are welcome to redistribute dyne:bolic in any way you like, to your friends and neighbours, to anybody who needs. Live long and prosper in Peace. But remember there is no Peace without Justice! The roots of Rasta culture can be found in Resistance to slavery. This software is one step in the struggle for Redemption and Freedom. This software stands up in the fight for digital rights! And Much blessings in Jah luv to all those who still resist. Selah. :: DOCKING RUNS FAST FROM HARDDISK To run dyne:bolic from your harddisk you just need about 600MBytes of free space on one of your partitions, then you put the CD inside while running your usual installed operating system (even winblows) and then you copy the /dyne directory inside your partition (at the root of your harddisk, like in C:\). That's it! now every time you boot from CD it will find the locally stored system and will use that, ejecting the CD as it is not needed anymore - so you'll also have a CD reader that you can use! :: ADVANCED SOUND COMPOSITION AND SYNTHESIS - DYNE:TRAX Dyne:bolic it's the FIRST GNU/Linux distribution including the state of the art in terms of GNU/Linux based free software for musicians: using the professional device support offered by the Advanced Linux Sound Architecture drivers, it includes the low latency daemon JACK-IT to connect together input and outputs of various sound applications, in fact offering a multiple audio rack composed of the great variety of free software available. Take care: that's where free software will beat proprietary systems! Interoperabilty between the many and different applications available in the GNU/Linux world, which instead of competing against each other they cooperate and work perfectly together to give you the widest range of possibilities ever. Spotlights on included multimedia software in this release: - PD in its latest version, complete with jack support and externals (iemlib, zexy and the video openGL GEM) thanks to the support given by the PD-stammtish crews in Graz: big up to IOhannes Zmoelnig, Tomas Musil and Michael Pinter for their help! see http://http://pd.iem.at - SpiralSynthModular is an object orientated music studio with an emphasis on live use. You can use it in a fairly straight forward way to make tracks with, or get very experimental. Audio or control data can be freely passed between the plugins. Data can also be fed back on itself for chaotic effects (all with JACK support!) see http://www.pawfal.org/Software/SSM/ - FreqTweak, ZynAddSubFx and JackRack to take the best out of your midi signals and render them into any possible combination of syntetized sounds.... see http://jackit.sf.net for more informations on how to use the JACK CONNECTION KIT Audio on GNU/Linux is a whole GNU world :) explore it from the great wsebsites and communities on http://www.linux-sound.org Dyne:bolic is also member of the linuxaudio.org consortium, expect more development and great attention on the field in the future of this distribution, which is allready employed by a growing number of musicians around the world. :: FREE ONLINE RADIO STREAMING Dyne:bolic was first born as a tool for network radio streaming, as a slick application for setting up free internet radios. Right now this keeps being a well supported functionality of dyne:bolic, besides all the rest. There is an increasing number of radios employing this software for streaming, among the others radio OndaRossa, radio Lora, radio Muda, radio Cybernet, radio Patapoe ... I'll do my best to keep it a steady and useful tool for that purpose! of course any comment and contribution, bugreport and more generally a collaborative and friendly approach to dyne:bolic features and bugs is very welcome. For more informations about the audio streaming software included inside dyne:bolic see __ _ _ http://muse.dyne.org :: REALTIME VIDEO MANIPULATION - FREEJ During the last period also FreeJ development made a leap forward towards usability, with a new GTK+-2 interface which you can see now in dyne:bolic, that lets you easily load movies, text and png images. This development was supported by the Netherlands Instituut vor Mediakunst / Montevideo Time Based Arts - where i'm currently hosted as an artist in residence. Also the involvement of Silvano "kysucix" Galliani and Christoff "mr.goil" Rudorff in the development has been a significative contribution - thanks to them you can be sure you'll see even more in future. Last but not least Anne-Marie Skriver also contributed with testing and good insights to the video functionalities you find in this version, while she is redacting also a FreeJ tutorial - soon on your screens! Please note the presence of XVidCap (desktop movie capture) software in this dyne:bolic release: now you can easily do movies out of your desktop! record everything you see in mpeg4 and other video formats. You are very welcome to contribute short movies as dyne:bolic demos and tutorials as well! the whole user community will surely benefit from that. for more informations about FreeJ see __ _ _ http://freej.dyne.org :: WHO MADE ALL THIS POSSIBLE ? This CD includes the work of several hundreds of people all around the world developing free software and GNU/Linux applications. without the efforts of this big communities dyne:bolic would have never existed, among the others are rastasoft.org, dyne.org, gnu.org and the Free Software Foundation, kernel.org, xfree86.org and more!

A quick note to say that I've just put together an interview with Han-Wen Nienhuys and Jan Niewenhuizen, of the LilyPond project, and it's now at http://www.linuxmusician.com/ . The interview is pretty long and covers quite a few subjects, and I think is a very interesting read. I'm very grateful to Han-Wen and Jan for doing almost all of the hard work. Chris

[linux-audio-dev] Glitchs using portaudio

by Ricardo Cirigliano

Hi! I´m using portaudio to capture continous voice using buffers of 200ms. I´m using 2 buffers in order to be able to make some process in one of them while I capture voice with the other one. However, every time I change the buffer that will receive the information a glitch occurs. Does anyone know how can I avoid this without using threads? Thanks!!!
