[linux-audio-announce] [ANN] Ceres V0.42 and Mammut V0.18

by Kjetil Svalastog Matheussen

http://www.notam02.no/arkiv/src/ CERES ***** "Ceres is a simple program for displaying sonograms and for sound effects in the frequency domain." Except that its not that simple anymore... 0.41 -> 0.42 ------------- -Actually apply the fix for the (horrible) bug that caused ceres to crash on newer linux distributions. (Sorry!) MAMMUT ****** Mammut will FFT your sound in one single gigantic analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms prior to resynthesis. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. 0.17 -> 0.18 ------------ -Fixed a (horrible) bug that caused mammut to crash on newer linux distributions. -Simplified the install process a lot. pygtk1, libglade and sndlib is now included in the distribution and is/can be installed automatically if needed. -Added undo for load&multiply --

[linux-audio-announce] [ANN] Ceres V0.41 and Snd-ls V0.9.1.5

by Kjetil Svalastog Matheussen

CERES ***** "Ceres is a simple program for displaying sonograms and for sound effects in the frequency domain." Except that its not that simple anymore... 0.40 -> 0.41 ------------- -Fixed a (horrible) bug that caused ceres to crash on newer linux distributions. -Simplified the install process a lot. pygtk1, libglade and sndlib is now included in the distribution and is/can be installed automatically if needed. -Connect to jack-server right after starting up ceres, not right before playing for the first time. http://www.notam02.no/arkiv/src/ SND-LS ****** Snd-ls is a distribution of the sound editor Snd. Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. 0.9.1.2 -> 0.9.1.5: ------------------- -Made the apply-button always apply to selection if there is a selection. -Removed some options from the edit-menu that interfered with the way snd_conffile works. -Made the insert-option in the edit-menu insert monofiles into the currently selected channel. -Added libxt-dev to the list of required packages. (Thanks to robin) -Made mono-files play in both left and right channel when using Jack. -Short fix for the nodeline-class. http://www.notam02.no/arkiv/src/snd/ --

Hi everyone, Sfront version 0.88 is released. You can pick up a copy at: http://www.cs.berkeley.edu/~lazzaro/sa/sfman/user/install/ index.html#download See change log below ... this release keeps sfront networking in sync with the IETF Internet-Drafts that define RTP MIDI (the RTP payload format for MIDI). See: http://www.cs.berkeley.edu/~lazzaro/rtpmidi/index.html for more information on RTP MIDI. --- sfront Version 0.88 -- 12/26/04 [1] Networking updated to match draft-ietf-avt-rtp-midi-format-07. Chapter M fields for A-BUTTON and C-BUTTON use new G bit layout and compute count for large values correctly. Sender supports the oldest-first log ordering for Chapters E/A/N. Sender supports new Chapter Q coding rule Start and Continue commands. SDP sent in SIP INVITEs uses rtp_maxptime and rtp_ptime, and uses correct SDP syntax. [2] The -sip_ip parameter now parses dotted-quads correctly. [2] Memory management bugs fixed (thanks to Graydon Hoare). [3] Correct value for PI used in code examples, book (thanks to Tiaan Geldenhuys). --- John Lazzaro http://www.cs.berkeley.edu/~lazzaro lazzaro [at] cs [dot] berkeley [dot] edu ---

[linux-audio-announce] Ardour 0.9beta22 released

by Paul Davis

I am happy to announce the release of Ardour 0.9beta22. With over a hundred notable new items, and only a handful of bug fixes between this and 0.99, this is a significant release of Ardour. Ardour's bug tracking database continues to have 260+ live bug reports and feature requests, and there are likely twice that number still present in the program, but we identified those that will be fixed for the 1.0 release in order to try to gain control of the release process. 0.99, which just might make it out by Christmas (December 25th, but don't hold your breath), will be the endpoint of code development for 1.0 per se - the difference between 0.99 and 1.0rc will be related to release engineering (making sure that the install of Ardour does all that it should). Fetch it here: http://ardour.org/releases/ardour-0.9beta22.tar.bz2 RELEASE NOTES FOR ARDOUR 0.9beta22 * Added support for midi parameter feedback. When enabled, controls that are bound to incoming midi events will send out that event when modified. This lets you control generic midi control surface with motor faders and/or led encoders (like the incredibly affordable Behringer BCF2000, which was used for testing), to match the internal state. Note the extra/changed options in the option editor's midi tab. Also note that automation playback does not yet send midi feedback. Reminder: to bind a fader or bar-control to midi, do a Control-Middle-Click on it, then send some midi control. * Added generic midi bindability for mute, solo, and rec-enable controls. to do it, you can do Control-RIGHT-click on the mute and solo buttons (the normal binding click is taken on these buttons for other functions). For the Record-enable button, it is the normal ctrl-middle-click. You can also pick it from the context menu of the mute button. A menu will be added to other buttons later. * fixed some midi prompter dialog issues * fixed some midi binding state saving issues * change entire buffer management scheme to be (more) RT-safe * add -V/--novst flag to avoid using VST even if it was compiled in * templates are mpeinstalled * major changes in thread handling to fix some serious errors in the way ardour handles threads when exiting. * make export work when sync'ed with JACK * add "timecode-source-is-synced" option to ardour.rc(.in) * new playlist selector (uses a tree structure in a scrolled window, instead of menus) * fix bug with MMC rec-enable handling (only odd-numbered tracks could be enabled) * make region export progress bar move in the right direction * more MTC slaving fixes and improvements (not done yet) * remove wrong-thread-calling of Session::clear_event_type(), which should help a number of loop-related crashes * remove erroneous use of "abort" in function call * new playlist selector * Automake-1.7 or higher is required for libmidi++ now. Should be pretty standard on distributions by now. * add "nudge by capture offset" operation for regions * enlarge playhead/edit cursor arrows a bit * avoid duplicate keyboard target registration * pay attention to "virtual" window enter/leave events, but continue to ignore "inferior" ones (fixes many keyboard focus issues) * cancelling tempo/meter create dialog doesn't insert a default tempo/meter marker * tempo/meter create dialogs have minimal WM decor, and use standard ArdourDialog API * 2d panner fixed in many ways (still not to my taste and not really correct) * context-click on panner shows context menu (Bypass is the only entry so far) * general panner state load/restore fixes * master outs added to connections menu * added optimizations for peak metering (use of fabsf, flag constants as floats, avoid implicit double/float casting) * handle disk over- and under-run errors in the GUI, and be more comprehensible to regular users. * remove zoom changes from the undo/redo history * fix panning bypass for 2d panner * fix stereo panner "mute" menu item so that it doesn't toggle panner mute state every time it pops up * add "OK" button and remove window decoration from "can't connect to JACK" dialog * sessions still load when audio files are missing or corrupt * complete redesign of slave-following design * stop disk-(over|under)run handler from executing in the wrong thread * fix appalling C/C++ bug preventing proper use of MIDI port tags * make solo/mute button mouse bindings more consistent with rest of interface (Ctrl-middle click is now used for MIDI learn here as well) * add solo button context menu * add new MessageWithConfirmation object to libgtkmmext * fix crash in handling DiskOverrun or DiskUnderrun messages * correct region fade in/fade out curves after split * fix complete loss of all optimization flags * added patch to allow snap-to-SMPTE-frames * add redo-ability of automation track "clear" operation * add optimization to AutomationList::_eval, and use same design in Curve::_eval * fix failure to use a search path when looking for templates * fix inserting zero-input plugins (divide-by-zero error) * improve sync-with-JACK after MTC slaving breakage * session events are no longer queued during session loading, which should reduce or eliminate JACK kicking ardour during startup. instead, these events are now processed by the GUI thread as the session is loaded. this stops the process() callback from potentially having a long list of things to do when its first called, thus causing JACK zombification. * recover-from-crash functionality a) all audio files get a header written into them at creation b) when session rec-enable is turned on, we store information about the files we'll be using for recording c) if ardour (or the computer) crashes during capture, ardour discovers this information, and uses the actual size of the audio files to modify their headers. new regions are then created and added that correspond to this data. d) there is GUI dialog to check on the user's wishes as to whether or not to use this "pending capture" information * clear-all-markers and clear-all-ranges no longer crash with no session * "duplicate client/no jack server" dialog grabs focus for its "OK" button * change all of libardour + gtk_ardour to use <stdint.h> types (uint32_t etc.) and <inttypes.h> for printf-style tags. a few "int" declarations remain. * redesign + reimplement plugin input/output count handling. try it and see. i think its way better. your mileage may vary. A note on the new scheme: a) sends are ignored entirely in figuring out plugin configuration. they send a signal *out* of the route, and have no effect on the flow within the route, so this seemed right to me. b) the first insert (plugin or port insert) is configured the match the input count of the route c) then we work *backwards* through the inserts to make them match the configuration of the previous insert. the output configuration of the last insert is left "free". d) we recompute in/out counts whenever we - add an insert - remove an insert - reorder inserts - change the input configuration of the route e) if the computation "fails" (i.e. no way can be found to make them work), the order is left as is, and an error is delivered via the GUI. * fix ancient bug in computing lengths of overlaps under 1 of the 4 possible types of overlaps. this fixes problems with chunks (and possible range ops) that extended to the end of the session (and beyond) * automation tracks now have some modest logic for handling height changes. alas, i can't hide the "expansion arrow" when i want to. * there is now a context menu for the region list display, complete with "Hide", which will move the region into a special subtree titled "hidden". I am still working on what a "Remove" option should actually do. * selecting a region in the region list selects all regionviews that are considered "region-list-equivalent" * mouse mode buttons never end up with 2 active at the same time * fix for new insert in/out counting scheme as it affects port inserts * libardour: 0.843.2 * fix deep order-of-operations problem that prevented Session->{Open,Recent,New} working with new plugin in/out code. * delete failed redirect, not just plugin, when adding a new plugin fails * fix for crash at session close caused by list iterator botchups (thanks to nick murtagh for discovering this one) * (in previous un-announced commit) patch from nick mainsbridge for crashing bug induced by tempo change * JACK sync is mostly working again * new, not necessarily improved Route::_reset_plugin_counts() (still a work in progress, debug output generated) * fix for crashing bug when deleting a plugin-based redirect * every use of the %f specification is now bracketed by enforced use of the POSIX locale (for libardour; GUI is still 100% locale-sensitive) * main transport clocks shown meter+tempo in BBT mode * CD markers+CD TOC/CUE patch from Nick Mainsbridge * all connections to Session signals made by editor are dropped when session is closed (avoids title bar being reset to show session name) * add new "mtc_qtr" signal to libmidi++, emitted every time an MTC quarter frame message is received. * redesign MTC slaving to sample apparent master speed from the process callback, rather than set it from the MIDI signal handlers. * attempt to use jack_client_open(), if its available. * alter --jack-client-name argument to be just --name, in keeping with some other JACK clients. * Ardour now handles JACK buffer size changes - note: VST plugins are likely not correctly handled at this time * move JACK related material to its own top-level menu bar item * better handling of JACK multiple disconnect/reconnect actions * add control for JACK buffer setting to that menu * make reconnect/disconnect to/from JACK sensitive at the right times. * finally (?) fix mouse mode buttons to work correctly at startup AND change default bindings of "r" and "g" * remove "disk rate" metering stuff from GUI * modularized mixer strip components internally * renamed the Route Parameters window to Track/Bus Inspector, redesigned to use tabs and the same context menu as the mixer strips. * rectified the plugin list handling in the mixer strip and the inspector window. * ardour_ui.rc is modified, so you might need to take action to get it used. The simplest way is to copy the new one to ~/.ardour/ardour_ui.rc * fix long standing bug where closing+saving a snapshot saved to the base version of the session. Thanks to Doug Mclain sticking with this bug until we finally got to the bottom of it. * make the "ask about saving" dialog use the snapshot, not session, name. * new metering design paves the way for 1.0 work on multiple meter points. the "pre" button is no longer a toggle, but a N-state button, where N is currently 3 (input/pre/post). Rec-enabling a track automatically switches to input metering. * if a diskstream cannot be rec-enabled because it has no known connections, check with JACK in case it was connected by starting from another JACK port. * catch "no more port" errors when using "Connections" * don't try to unregister non-Ardour JACK ports * encapsulate and rationalize the way diskstreams switch between audio files before capturing, and how they store capture pending info. This fixes several crashing bugs reported by Doug over the last 10 days. * handle block size changes for VST plugins. Note: some VST plugins do not handle this correctly, and will cause crashes. * remove call to VST "resume" method from process() thread. This *may* have some ramifications for certain plugins that don't understand the intended thread relationships for a VST host. Haven't seen them yet myself. * fix ordering of creating the "Master Outs" "Connection" and the Master bus ports. This bug has led to some potentially nasty stuff happening with session files that appear to drop all connections from tracks to the master bus. [ Not totally solved. ] * Ardour will build on macosx out of CVS now, with the right toolset installed on OSX and recent JACK CVS. * playlists now have "frozen" property. - frozen playlists cannot be selected by any track. they are accessible only by freezing or re-freezing a track. * rec-enable buttons and playlist selector buttons start out insensitive if a track is frozen at load time * some modifications to ArdourMessage to make it even easier and more consistent to use. * make "cannot record - no inputs" message more useful, informative, explanatory and use ArdourMessage. * remove middle click mutes regions behaviour (for safety) * add behaviour to the meter button that is similar to the mute/solo buttons: shift-ctrl-click adjusts all metering ctrl-button2-click is momentary ctrl-button1-click affects mix group * cleanup improvements (SIGNIFICANT) - fix stupid bug that led to sources having paths with "//" in them. this meant that string comparisons between paths found using a directory scanner and the source paths would fail to see them as identical, and would conclude that the file was not being used withing the session. - remove peakfiles for files that are moved into dead_sounds - actually unlink files when the wastebasket is cleaned out - search all snapshots to ensure that cleanup does not remove files used by one snapshot and not another. * sample rate indicator now includes period size indicator in msecs
