[linux-audio-dev] [ANN] AlsaModularSynth 1.8.1

by Matthias Nagorni

Hello, a new version of AlsaModularSynth is available from Sourceforge. Note: Remember to download the latest version of the LADSPA plugins by Fons Adriaensen: http://users.skynet.be/solaris/linuxaudio Otherwise the latest instrument patches just won't work ! News: - Added hplp_instrument.ams which demonstrates the new highpass filter by Fons Adriaensen. Due to the HPLP combination, the presets of this patch are quite close to some of the famous "Switched-On Bach" sounds by W. Carlos. - Added sinfonia.mid for your own experiments with hplp_instrument.ams - Fixed bug in LADSPA module where uninitialized output control ports have caused segfaults. - Several small corrections in demo patches. For more news check the respective section on the project page. Have fun !

[linux-audio-dev] regarding mobos and CPUs

by Dave Phillips

Greetings: A client has asked me to get some opinions regarding AMD CPUs and recommended motherboards. He's planning to replace an SMP system that has apparently never worked quite right. He doesn't want another SMP mobo, and a friend is advising him to go with a uniprocessor system built around a recent AMD CPU. The recent JACK problem with AMD CPUs was a revelation for me: I'd never had any problems with AMD chips, but now I'm feeling reluctant to recommend them. Am I just being paranoid, or are there particular reasons to go with Intel instead of AMD ? My client is considering a P4 instead of the AMD, hence this infoquest... Also, what's a recommended motherboard ? Are there any mobos that should definitely be avoided ? TIA for any help you guys can proffer, it's much appreciated. Best regards, dp

What is the problem with JACK and AMD cpus? I haven't heard of one. Personally, I have an nvidia nforce2 motherboard which has worked fairly well for me.

Re: [linux-audio-dev] regarding mobos and CPUs

by Taybin Rutkin

Yes, that was just an autotools problem. It could have happened to a P4 if jack was built on an AMD box. It was more of a cross-compilation issue.

The problem was simply and quickly solved, and I'm perhaps off-base accusing JACK but that's where the problem came from. Maybe it was a bad make ? Anyway, if it's the opinion of the LAD developers that AMD is OK then that's what I need to know. As I stated, I've had only that one difficulty with AMD and Linux audio software, so I think I'm just being paranoid. Best, dp

There are no > limitations on how many vsti's you run simultaniously. My apologies... My dev knowledge is too low to be mentionned. Additionally, French people like me don't always speak English very well ,-) I've definitely made this thread confusion during my tests, as I tried to launch two plugins simultaneously, both with vsti, and had VSTserver return errors... Had just another go today, works perfectly! Mea culpa. When it comes to limit the number of opened console windows, how should I define my paths correctly system-wide? On Fedora Core 1 - seems to be relevant in this case - appending "export VST_PATH=..." to the file /etc/profile and sourcing it afterwards does only define the path for console use. When using the launcher (Alt+F2) to start plugins with "vsti plugin_name", it doesn't seem to recognize VST_PATH. > The difference between the vstserver and the new fst-library made by > Torben Hohn and Paul Davies is that the fst-library runs the vst-plugin > in the same process, while using the vstserver-system you run the > vst-plugin inside a new process set up by the vstserver. > > What this means is that you get less contex-switches and therefor > better performance when running many (something like more than 8 according > to Paul) vst-plugins simultaniously using the fst-library. What kind of features are already planned for the next releases of both projects? Cheers, Christian

[linux-audio-dev] Linux Audio weblog

by Jan Weil

Sorry for cross-posting. Hi all, now that my new website is online I'd like to let you know that I recently added a 'Linux Audio' path to my weblog. This is meant as an offer to all those who find themselves continuously struggling with lots of postings to LA* & Co. Of course this can only stand for my point of view and I won't claim for completeness. http://www.jawebada.de/index.cgi/blog/lad Regards, Jan

Re: [linux-audio-dev] (web-based) interactive sound art?

by Pall Thayer

Hi people, First of all, I wonder why no-one has thought to contact me to ask about these points brought up about my work. Anyway, I'd be happy to explain a couple of things like why I use Flash, Java and Mp3 even though they're proprietary. I would be very happy to get away from proprietary technologies completely but I also want people to be able to enjoy my work with minimum effort. I am of course aware of SVG and OGG and do most of my work on Linux (except Flash of course). However, although we all love non-proprietary software and platforms, they are seldom pre-installed on 'regular' users computers. If they drop in at a site that requires that they download and install not one, but two or three plug-ins or programs, they're just going to skip the site and go to the next one. I would. I could try to be really modest and say, "I don't care what anyone else thinks or says, I'm just doing this for myself!" But that just wouldn't be true. I'm doing this for an audience and the bigger the better. I want people to experience and enjoy my work and I know they won't if it involves a bunch of downloading and installing. I have been moving towards Java instead of Flash specifically because Flash doesn't run well on Linux and with Java I can do all my work on Linux. On the issue of GPL-ing my stuff. I'm just not that organized. If anyone wants to see my files, just contact me and ask. I have nothing against sharing them and do whenever anyone requests it. best regards, Pall Thayer artist/teacher Fjolbrautaskolinn vid Armula http://www.this.is/pallit http://www.this.is/pallit/isjs http://www.this.is/pallit/harmony http://130.208.220.190/panse

[linux-audio-dev] RME HDSP ALSA driver

by Simon Pietroni

Hi all, I hope this is the right place to be asking this. If not, please forgive me, and point me in the right direction. I'm trying to get my RME HDSP9632 card working under SuSE Linux. I've built ALSA 1.04, and it can see my Soundblaster fine, but when I modprobe snd-hdsp, it cannot find the RME card. The card shows up in lspci with revision 0x97, and I'm wondering if this card/firmware is too new to be detected by the latest ALSA drivers. Any help or guidance anyone can give me would be greatly appreciated. Many thanks, Simon Pietroni.

[linux-audio-dev] libfishsound-0.6.1

by Conrad Parker

FishSound 0.6.1 Release ----------------------- libfishsound provides a simple programming interface for decoding and encoding audio data using Xiph.Org codecs (Vorbis and Speex). This release is available as a source tarball at: http://www.annodex.net/software/libfishsound/download/libfishsound-0.6.1.ta… New in this release: * Fixed bug in decoding stereo Speex to non-interleaved * Added fish_sound_{get,set}_frameno() functions * Added API for reading and writing Vorbiscomment style metadata * Added test suite for comment read/write integrity * Added comprehensive testing of encode/decode pipeline libfishsound by itself is designed to handle raw codec streams from a lower level layer such as UDP datagrams. When these codecs are used in files, they are commonly encapsulated in Ogg to produce Ogg Vorbis and Speex files. libfishsound is a wrapper around the existing codec libraries and provides a consistent, higher-level programming interface. It has been designed for use in a wide variety of applications; it has no direct dependencies on Annodex or Ogg encapsulation, though it is most commonly used in conjunction with liboggz to decode or encode Ogg encapsulated Vorbis or Speex files. FishSound has been developed and tested on GNU/Linux, Darwin/MacOSX and Win32. It probably also works on other Unix-like systems via GNU autoconf. For Win32: nmake Makefiles, Visual Studio .NET 2003 solution files and Visual C++ 6.0 workspace files are all provided in the source distribution. Full documentation of the FishSound API, customization and installation, and complete examples of Ogg Vorbis and Speex decoding and encoding are provided in the source tarball, and can be read online at: http://www.annodex.net/software/libfishsound/html/ FishSound is Free Software, available under a BSD-style license. More information is available online at the FishSound homepage: http://www.annodex.net/software/libfishsound/ enjoy :) -- Conrad Parker Senior Software Engineer, Continuous Media Web, CSIRO Australia http://www.annodex.net/ http://www.ict.csiro.au/cmweb/
