[linux-audio-dev] [ANN] LADCCA 0.4.0, ALSA Patch Bay 1.0.0, JACK Rack 1.4.3

by Bob Ham

Hi all, LADCCA's now reached a state where I reckon it's worth releasing again. It's pretty stable for me, and it now seems to do what it should without any hiccups. I'm releasing alsa patch bay and jack rack along with it as the only changes are support for the new ladcca version. ALSA Patch Bay has had 1.0-ness for a while now so I'm taking the opportunity to bump the version. There's only two other supported apps at the moment, muse, which already has 0.4.0 support in cvs and fluidsynth, a patch for which is included in the tarball. From the ladcca NEWS file: * low level tcp protocol has changed along with a lot of structure clean ups on the client- and server-side. * added low level protocol versioning * well defined server interface protocol (that works! :) this has been the bulk of the work that's added two more properties to cca_event_t, client_id and project, bumped the major version of the high level protocol and caused more changes to the low level protocol * new high level normal client event, CCA_Server_Lost * removed CCA_Use_Jack and CCA_Use_Alsa client flags; sending the server the jack client name or alsa client id now suffices * major amounts of cleanups and fixes * server now saves project info in XML which means a new dependency on libxml2 * socket stuff now uses protocol-agnostic system calls and the server defaults to IPv6. an entry in /etc/services is required to support this. make install will install an entry if there isn't one present. this can be disabled with a configure option, --disable-serv-inst. there's also a new option for ladccad, --no-ipv6 which, suprisingly, stops the server using ipv6. * the --with-default-dir configure option and -d ladccad option now set the directory relative to $HOME, rather than being a system-wide directory * project directories now get cleaned up if they haven't been saved * updated the manual Patches * fluidsynth cvs http://pkl.net/~node/ladcca.html http://pkl.net/~node/alsa-patch-bay.html http://pkl.net/~node/jack-rack.html Bob -- Bob Ham <rah(a)bash.sh> "At some point, keystroke recorders got installed on several machines at Valve. Our speculation is that these were done via a buffer overflow in Outlook's preview pane." -- Gabe Newell on the Half-Life 2 source leak

[linux-audio-dev] some more GMPI thoughts

by "horsh

1)is API monolithous or there are sub-APIs like GMPI-audio, GMPI-seq, GMPI-control 2) Explicit versioning for API? 3) Explicit versioning for plugins? 4) uniq IDs for plugins? who is authority? 5) format for plugin state saving: XML? (damn its ugly!) I vote for more YAML-like language. 6) Should the GMPI discussion produce reference plugin implementation reference host implementation reference tools implementation 7) Can there be off-line non real-time plugins? 8) Should the specification produce any requirement for more documents? For example: A documant describing standard set of plugins (like in General Midi) so one could expect the first 64 plugins to be so and so. horsh

Re: [linux-audio-dev] GMPI - requirements

by "horsh

Well it's just requirements? Then what about : 1) jack-transport-like and 2) LADCCA-like functionality? the requirement resolution could sound as: "GMPI does not need such functionality", but if it souns as "GMPI _does_ need..." then it would be very welcome. horsh ====================8<========================== One of my tasks as part of GMPI is to provide a draft of the requirements doc. I turn tp you all. If you have requirements that you think should be in GMPI - please let me know. These have to be requirements. Not handwaving though explosions, and not wishful dreaming. Things that are required or desired that will make GMPI be the open music platform we need. Feel free to email me privately or publicly. I'll be happy to condense ideas and to extract requirements from whatever you have for me. Trying to get the ball rolling again... Tim

[linux-audio-dev] Performance utilities of the future.

by Robert Jonsson

Hi, This seems like an interesting article, describeing a new kernel service/application in 2.6. http://www-106.ibm.com/developerworks/library/l-oprof.html?ca=dnt-441 It's called OProfiler. "OProfile can help you identify issues such as loop unrolling, poor cache utilization, inefficient type conversion and redundant operations, branch mispredictions, and so on." Just thought I'd pass it on. /Robert

[linux-audio-dev] jack: what does this mean ?

by Sascha Retzki

Hi. Well, you know I am a novice in everything related to linux & audio ;), but THIS: jackd: pcm.c:5959: snd_pcm_mmap_begin: Assertion `pcm && areas && offset && frames' failed. received signal 6 during shutdown (ignored) is an alsa-error, right ? I could not find an answer on the question what it means, so maybe some of you can ... greez, Sascha Retzki _____________________________________________________________ Linux.Net -->Open Source to everyone Powered by Linare Corporation http://www.linare.com/
