[linux-audio-dev] lash directions

by Bob Ham

Hi, One of the things that I came away from the meeting in Germany with was a sense that the LASH protocol used for client<->server communication needed to be better defined, both on the wire and in the api. What is really necessary is a network protocol and api designed to allow high-level ideas like sessions to be represented in a simple format. The properties that I had been working on have become gobjects and what was to be a new networking system is a seperate, gobject-based library to provide a high-level networking api (eg, session_scan(), session_join(), etc) The TLA OSC has been banded about quite a bit, and this is not out of the question; it would be in a set of usable lower-level protocols (or perhaps the set :) Bob -- Bob Ham <rah(a)bash.sh> /-\ \ / Gay Whales X Against Racism / \

[linux-audio-dev] [ANN] libclalsadrv-1.0.1

by Fons Adriaensen

Hello, An updated version (1.0.1) of libclalsadrv is now available on <http://users.skynet.be/solaris/linuxaudio> Changes w.r.t. 1.0.0: snd_pcm_prepare() is no longer called when the alsa device is started, only when it is restarted after an xrun. This seems to solve some problems with 2.6 kernels. Thanks to Matthias Nagorni and Takashi Iwai for finding this out. -- FA

With scroll-button mouses (which everyone should use), the middle button is very unconfortable. What about some creative use of the scroll-wheel instead? The obvious use is of course to change the value with the scroll-wheele. I think that would be nice. > > There have been some drawing errors happening > when moving the fan out to one side and then > the other in one go.

How about double-buffering the thing? Another thing, in some situations, I think I would prefer that the fan is always at maximum size. Could that be made as an option in the API? Besides from that, very very nice! I'm thinking about using it in my configuration code for SND. But the flickering needs to be fixed. --

[linux-audio-dev] [ANN] PHAT version 0.1.0

by Pete Bessman

I'm pleased to annouce, after a solid month of heated debate with X11, the initial public release of PHAT, the PHat Audio Toolkit. From the website (www.gazuga.net/phat.php): "PHAT is a collection of GTK+ widgets geared toward pro-audio apps. The goal is to eliminate duplication of effort and provide some standardization (well, at least for GTK+ apps). It's open source software, licensed under the GNU GPL, version 2.0 or later." The debut and flagship widget is the fanslider, designed by Thorsten Wilm's. The LAU folks may not be too interested in the library as such, but might like to play around with this widget (hence the cross post). It comes with a demo program, "phatfantest," which displays the sliders in all their glory. Tarball: www.gazuga.net/phat-0.1.0.tar.gz Docs: www.gazuga.net/phat/index.html Let's actually go somewhere with all this debate about widgets and standards and such. Contributions are welcome (hint hint). I hope we can put an end to the Linux Usability Curse, at least in our own little neck of the woods. -- Pete www.gazuga.net ===================================================================== "I saw the movie 'I, Robot' recently, a film based loosely on a book written by science fiction author Isaac Asimov. In case you're not familiar with Asimov's writing, here's a list of things the movie had in common with the book: * The title."

[linux-audio-dev] [ANN] ladspar 0.1

by Hans Fugal

ladspar is a Ruby module for using LADSPA plugins. Here's a short example: --- require 'ladspa' require 'narray' # load the CMT library cmt = LADSPA.load_library('cmt') # get an instance of the amp_mono plugin amp_mono = cmt.plugins.find {|p| p.label == 'amp_mono'}.instantiate(44100) # The ports are Gain, Input, and Output. amp_mono.ports[0].connect_port(1.5) # gain input = NArray.sfloat(44100) amp_mono.ports[1].connect_port(input) output = NArray.sfloat(44100) amp_mono.ports[2].connect_port(output) amp_mono.activate if amp_mono.has_activate # prep the input data ... amp_mono.run amp_mono.deactivate if amp_mono.has_deactivate amp_mono.cleanup --- This is the first release of ladspar; I consider it beta quality. I have put it through its paces (more test code than swig code), but I am the only one to have tested it. Nevertheless I think it is usable, and I am eager to fix any bugs you may find. Go grab it at http://rubyforge.org/projects/ladspar -- .O.

[linux-audio-dev] Re: OSC for GUI-Engine communication

by Juhana Sadeharju

>From: Dave Robillard <drobilla(a)connect.carleton.ca> > >The question is, which implementation is best? All I can find is >Steve's liblo, libosc++, and the 'official' OSC kit. What are the >advantages/drawbacks of each? I can find very little information on any >of them. Last I checked OSC, it had Lisp/Scheme like syntax. Don't know if that is a drawback --- anyone? Has anyone used MPI (Message Passing Interface) for this? People use these for high performance parallel computations in Linux clusters. MPI itself is a standard supported by academic and by vendors. MPI is used, e.g., in supercomputers. See, e.g., http://www.csc.fi/reports/pc-cluster/Finalreport.pdf Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software
