[linux-audio-dev] [ANN] jamin-0.9.0 release

by Jack O'Quin

The second stable release (0.9.0) of JAMin - the JACK Audio Mastering interface is now available for download. JAMin is a GPL-licensed, realtime mastering processor designed to bring out the detail in recorded music and provide a final layer of polish. Every effort has been made to ensure a clean, distortion-free signal path. All processing elements use linear-phase filtering to eliminate phase distortion. JAMin runs on Linux using the JACK Audio Connection Kit, a low-latency audio server. JACK connects multiple applications to a single sound device, and also share audio among themselves. We rely on other JACK applications (like ardour, ecasound, or rezound) for playback and recording. Homepage http://jamin.sourceforge.net/ Download http://prdownloads.sourceforge.net/jamin/jamin-0.9.0.tar.gz?download New dependencies (since jamin-0.8.0) swh-plugins >= 0.4.6 <http://www.plugin.org.uk> liblo >= 0.5 <http://plugin.org.uk/liblo> (optional, for OSC scene change control) All other dependencies remain unchanged, the README file has a complete list. Usage instructions http://jamin.sourceforge.net/Using_JAMin.html Changes since jamin-0.8.0 * Limiter improvements: -- uses new fast lookahead limiter (LADSPA:1913) from the swh-plugins >= 0.4.6. The old limiter had some undesirable sonic artifacts. -- changed order of final gain and limiter stages. * OSC control for scene changes: -- accepts "osc.udp://localhost:4444/jamin/scene" messages -- new `jamin-scene' command sends them -- new jamin-cont plugin (LADSPA:1912) sends scene change messages to the JAMin process via OSC. (This plugin works with ardour, ecamegapedal and applyplugin, but segfaults in jack-rack when removed.) * Increase number of scenes from 6 to 20 * GUI improvements -- extensive context-sensitive help -- color editor for highlights and text -- options pulldown menu for spectrum, crossfade, and EQ * Better bypass control -- specific bypass controls for EQ and limiter -- separate Active/Solo/Bypass for each crossover band * Global state settings saved in XML file. * Expanded Russian translation * Many bug fixes. -- joq

[linux-audio-dev] liblo moved to sf.net

by Steve Harris

http://sourceforge.net/projects/liblo/ Theres a mailing list, liblo-devel. For those who dont know, liblo is a GPL'd implementation of the OSC protocol, which is a Remote Procedure Call language, designed for audio software. http://www.cnmat.berkeley.edu/OpenSoundControl/ I feel that liblo is now mature enough to stand on its own, so I'm moved it to sourceforge. I welcome help and advice from anyone who feels like giving it, though I do want to stop the API getting too sprawly. The current state is that I've just added UNIX domain and TCP transport support, but they are a bit rough around the edges. The current contents of the TODO list are: * Bundle support [needs NTP, argh] * Add source address to received messages * More/better regression tests * More/better example code * Normalise URI handling [needs discussion] * GTK/Qt/etc. tie code [maybe belongs in another library] * OSC pattern matching [still not sure about this one] * Rendevous/OpenWhatever (eg. howl) service discovery [low priority] * Add a JACK transport layer [maybe, low priority] * Make TCP work to spec (currently the TCP server only reads the 1st packet from every conneciton) [low priority] Cheers, Steve

[linux-audio-dev] ardour 0.9beta19 released

by Paul Davis

(not the "feature complete" release I was planning, but the list of changes is enough to warrant a new beta number) Changes since 0.9beta18.4: * optimization flags patch from rob holland * drag-n-drop onto the editor track area where there is no track creates an appropriate track (or multiple, if appropriate) * URL-decode drag-n-dropped filenames * numlock can no longer mess up region dragging - if numlock generates whatever "Meta" is supposed to be then Ardour changes its notion of what Meta is. - if you see a warning about this in the terminal at startup, you should fix your keyboard map using xmodmap or equivalent * remove debugging output from process() tree * removed VST audiomaster callback debugging output * UI for VST plugins now offers presets * VST plugins now save and restore their state - "chunk"-using plugins are not yet supported * initial tempo and meter markers cannot be moved, even after editing * when cleaning up, prompt user about each unused playlist (options are delete, keep, cancel cleanup) * never decrease the number of panning buffers * Can't create a new session on top of an old one anymore. It didn't overwrite the old session, but you would get 2 master tracks and whatever was in the template, if any. * freezing tracks - implementation of freeze completely redone - unfreeze now works across invocations of ardour, so you can freeze, exit, restart and unfreeze. - freeze hides any insert editors, makes rec-enable and redirect display widgets insensitive and locks the new region. - freeze can be used over and over again * reworked relationship between bounce + freeze * removed "Loop Region", renamed "Loop Selected Region" as "Loop Region" because of click-selects selection model * finally made solo button in mixer strip have the same font size as other buttons * removed edit history button and associated code from editor track * removed "automation style" buttons since they did nothing * more automation line + point patches from gerard * fix a couple of valgrind complaints * region trimming now obeys ignore-snap modifier * search unused playlists in Session::playlist_by_name() * added 2-phase unserialization mechanism (Session::StateReady signal) * empty playlists assigned to correct diskstream at startup * removed some debug printfs and some dead code * make Shift_R work like Shift_L * fix crashing bug with zero-length fade ins * internationalize all editor operation strings * transport control is insensitive when there is no session * fix problems with "region->fill track" where region is at or beyond current session end * new mixer strips use the current default width setting * always save to snapshot * snapshotting changes the current snapshot to whatever was saved * delete click_io object at session close, thus allowing new sessions to load correctly * fix problem with code ordering in normalize-region operation (undo after normalize-then-cut will now do the right thing) * force selection.clear() in file selection browsers when widget selections are cleared * committed patches so that ardour now compiles with gcc-3.4. There were several patches from multiple people. So please let me know if I missed one. * patch from nick_m that fixes a problem with the editor-mixer button.

[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.

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. --
