[linux-audio-announce] [ANN] ecasound 2.2.0 released

by Kai Vehmanen

1. A short summary of changes Support for JACK and LADSPA 1.1 added, more intelligent runtime parameter selection, ECI licence changed from GPL to LGPL, new NetECI client API, ecasound emacs mode added, largefile support, new resample, reverse and typeselect audio objects, new peak amplitude chain operator and new utilities ecalength, ecamonitor and ecasignalview. --- 2. What is ecasound? Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licenced under the LGPL. --- 3. Changes since last release Although over a year has passed since the last major stable release, ecasound development work has not stopped. To put things into perspective, a diff between 2.0.0 and 2.2.0 takes about 1.7MB of space. Considering the whole 2.2 codebase is just over 2MB, this is quite a lot! In the future there will hopefully be much more frequent releases. Here's a list of most notable changes: * Intelligent parameter configuration. Instead of one set of default parameters, ecasound lets user specify different parameters for three predefined profiles: real-time, real-time-low-latency and non-real-time. When starting processing, ecasound will automatically select and use most suitable profile for the given configuration. Ecasound will not only consider the types of objects, but also the runtime environment: whether it is possible to lock memory, to use RT-scheduling and so on. * The Ecasound Control Interface is now licensed under LGPL. In addition, the ECI implementations are now standalone, and do not require linking against libecasound and libkvutils. Only thing needed to run ECI apps is to have a working ecasound executable installed. * JACK support added. This is a major new addition as it involved making relatively large changes to the ecasound engine. * Up-to-date support for ALSA-0.9 and LADSPA-1.1. * Effect preset improvements. Support for parametrized presets has been improved. For instance it's now possible to write a wrapper effect preset for a complex ecasound effect or LADSPA plugin, and only publish a subset of original effect's parameters. * The disk i/o buffering subsystem that was introduced in ecasound 2.0 has been integrated more closely to the ecasound engine leading to better performance and reliability. * NetECI API. Ecasound now has a daemon mode that allows multiple clients, using the NetECI protocol, to connect to a running ecasound session. A proof-of-concept client, ecamonitor, is included in the package. It can be used to monitor ecasound session status from a separate console. This is especially useful in combination with ecasound's console mode user interface. The console interface can be used for control and the NetECI monitor client for getting real-time status information. In addition, NetECI can be used with all ECI apps. * Ecasound.el, an emacs ecasound mode and a Lisp ECI implementation. * Largefile support for reading and writing audio files larger than 2GB. * New audio object types: JACK, resample, reverse, typeselect. * New chain operators: peak amplitude monitor * Utilities: ecalength and ecamonitor added, ecasignalview totally rewritten. * New ECI implementations: Lisp, Perl and PHP (the last two are not included in the main ecasound package) Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes * Command line options: 2.2 is backward compatible with 2.0 releases, so old scripts and .ecs files should continue to work. See ecasound(1) for more info. * Ecasound Interactive Mode (EIAM): No changes to the commands available in 2.0 releases. See ecasound-iam(1) for more info. * Library interfaces: Major changes in all library interfaces. Direct use of these libraries is no longer encouraged. The ECI and NetECI APIs are preferred for developing new applications on top of ecasound. * Ecasound Control Interface (ECI): No interface changes. * The ~/.ecasoundrc config file is no longer used. The new location is ~/.ecasound/ecasoundrc. As there's now a separate global configuration file, it is no longer necessary to duplicate all config variables in the user config files. See ecasoundrc(5) for further info. --- 5.

[linux-audio-announce] [ANN] swh-plugins 0.3.4

by Steve Harris

http://plugin.org.uk/releases/0.3.4/ Hods of changes, including: * Bugfixes to GSM sim (Pascal Haakmat) * Bugfixes to FM osc (Pascal Haakmat) * Bugfixes to audio divider (Nathaniel Virgo) * Added another compressor, SC4, stereo, no sidechain * Added lookahead brickwall limiter * Added L/C/R delay (requested by Marek Peteraj) * Added Giant flanger (kind of requested by Patrick Shirkey) * Added DJ Flanger (actually requested by Patrick Shirkey) * Should now compile on FreeBSD * Fixed syntax error in RDF metadata, works with Bob H's jack-rack now I've updated the AUTHORS list, but I've undoubtedly forogtten people, so if youre not in there and should be give me a shout. SC4 is more-or-less like SC3, but has no sidechain and a subtly different algorithm. The sidechain was confusing hosts. The limiter has up to two seconds of lookahead, so can be very gentle. The L/C/R delay might be a bit familiar to Korg Trinity users ;) I haven't used it much bet it seems pretty cool. The giant flanger was a mistake, but I left it in anyway. The DJ flanger hjas controls for LFO period (instead of frequency as you would have in a synth) and you can resync the LFO by clicking a toggled control*. - Steve * This reminds me, there would be a use for a MOMENTARY hint (implying or requiring TOGGLED) in LADSPA, that meant that a control port should only be held high while the UI control was held down, otherise you have to double click reset controls, which is confusing.

[linux-audio-announce] [ANN] JACK Rack 1.1

by Bob Ham

Hi all, Nice couple of new features with this release, a lot of code cleanups, a bit of UI work, and general betterness all round :) And, if I'm not mistaken, this makes jack rack the only application so far with LRDF support. Nee ner nee ner ;-) * proper ladcca support (pays attention to events) * added saving/loading rack configurations. this is a bit of a hack tho as when you open a file, it only adds the plugins to whatever's in the current rack. in fact, the whole of the file loading/saving is hairy atm. * added lrdf support (this is majorly phat.. categorised plugin menus :) * proper toolbar with stock buttons * control rows now have no central port label * added a menu bar * added a splash screen * added an about box (using gnome 2) * nice new icon and logo images, used for the splash screen, the window icons and also a gnome 2 .desktop * lots of code separation and cleanups and under-the-hood changes http://pkl.net/~node/jack-rack.html Bob

by Pascal Haakmat

GNUsound is a sound editor for Linux/x86. It supports multiple tracks, multiple outputs, and 8, 16, or 24/32 bit samples. It can read a number of audio formats through libaudiofile, and saves them as WAV. GNUsound supports a large number of high-quality audio effects through the LADSPA plugin architecture (see http://www.ladspa.org). GNUsound 0.5.1 adds an amplitude treshold module, fixes a cuepoint drawing bug, fixes the behavior of the fast-forward/fast-rewind buttons, fixes a potential crash in the LADSPA dialog, and fixes a GCC 2.95 compilation problem.

[linux-audio-announce] Ceres V0.37, Mammut V0.14, Vstserver V0.2.5

by Kjetil S. Matheussen

Ceres **************************** Ceres is a program for displaying sonograms, sound effects and editing in the frequency domain, import and export of various (obscure) non-audio file-formats (csound, matlab, PBM, etc.). 0.36 -> 0.37: ------------- -Fixed broken LPC. -Fixed very serious bugs in the "sieve", "Spectrum shift" and "Spectral subtraction" transforms. Bugs introduced in V0.30. *They should now sound correct.* Oops. -Fixed a semi-serious bug in the convolve transform. -Added "make install" to the makefile. Set the "INSTALLPATH" variable in the makefile. -Removed some debug printings. Mammut ***************************** Mammut will FFT your sound in ONE single gigantic analysis (no windows). An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. You must have a certain attitude when using this program. Use it experimentally, by ear. Do not try to understand what happens - even the programmer can't explain it in many cases. 0.13 -> 0.14: ------------- -Fixed the rest of the transforms to support more than two channels. -Updated the version number in the about dialog from 0.12 to 0.14. Vstserver ***************************** Vstserver is a program that must be running when using programs using vstlib. Vstlib is a library that can be used by programs to run windows vst audio plugins under linux/freebsd/i386solaris/etc. 0.2.4 -> 0.2.5: --------------- -Reorganized the source a bit. -Fixed (sort of) broken LOCKS_new function, and added a check for possible deadlock. -Included the vst include files into the distribution. -Removed the modified aeffectx.h file, it was perhaps a violation to some licence to include it. Included a diff-file instead. :) aeffectx.h is now automaticly patched by the makefile. -Test for kEffectMagic when opening plugin. -Added a version-test to vstserver to avoid having a client compiled with a different version of vstlib trying to start a plugin. -Again, you have to recompile all programs linked with vstlib.a after upgrading. Will make a shared library as default when the API settles. Everything may still change. (However, this is not a very important upgrade from 0.2.4.) *************************** Download from http://www.notam02.no/arkiv/src/ --

[linux-audio-announce] |ANN| Autocomp 0.0.5

by Wayne Myers

Hi, Autocomp is an automatic accompaniment generator for Perl and Csound, developed on Linux. It's an attempt at a practice utility for musicians. Freshmeat project page is here: http://freshmeat.net/projects/autocomp/ Download it or read more here: http://www.waz.easynet.co.uk/software.html Currently there is only one style of output, which is a pastiche of a 'swing' style with a walking bassline. The output is heavily on the gorgonzola side of cheesy, but it's already at a stage where you can practice with it if you don't mind the cheese level. All comments/suggestions etc gratefully received. Cheers etc., Wayne -- Wayne Myers http://www.waz.easynet.co.uk/
