[linux-audio-announce] [ANN] Ecasound 2.3.3 released

by Kai Vehmanen

Hello all, this year's first stable Ecasound release is now out! Most of the final tuning for this release was done last Sunday while watching and listening to the last sessions of 'laconf2'. Many thanks to all the organizers and participants! And special thanks for the excellant net coverage of the event! But now, back to the 2.3.3 release -- here are the details: 1. Summary of changes Bugs in ecasignalview, effect presets, NetECI protocol parser and the C ECI implementation have been fixed. Many build system issues, including errors in building against libsndfile-1.0.4 and older, have been resolved. A separate section covering ecasound.el, the ecasound emacs interface, has been added to the Ecasound Control Interface Guide. The Ecasound User's Guide has also been updated. --- 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 licensed under the LGPL. --- 3. Changes since last release * Preset handling fixes: When saving chainsetups containing presets, values of preset parameters were not saved correctly. Also problems with presets containing untitled parameters have been fixed. * New ecasoundrc(5) setting "autodetect" for "default-output" has been added. When selected, libecasound will check for JACK support and whether a JACK server is running, if not found, check for ALSA, then OSS, and finally fallback to using "rtnull". This feature is especially useful to apps such as ecaplay. * Fixes to ecasignalview: Proper cleanup after receiving an interrupt from keyboard (SIGINT/CTRL-C) has been added. Originally tested on FreeBSD, but helps on Linux as well. * Ecasound Interactive Mode (EIAM) updates: Added new command 'map-ladspa-id-list' to allow listing the available plugins by their unique ID numbers. A special case value of '-1' is now understood by 'cs-set-length'. This allows undoing any previously set length value. * Ecasound Control Interface (ECI) updates: Added a section on ecasound.el - the Ecasound emacs interface - to the ECI Guide [1]. Several bugs have been fixed in the ECI C implementation. A serious bug in NetECI protocol parser, that caused parsing long (over 32 chars) commands to fail, has also been fixed. * Documentation updates: The Ecasound User's Guide [2] has been updated. Also, a bug in the groff source for the ecasound(1) man page that prevented man from showing the last five pages of the document, has been fixed. * Build system fixes: Problems in building against libsndfile-1.0.4 and older have been fixed. 'libecasound-config --libs' has been fixed to return the full list of external libraries. Based on recent discussions on linux-audio-dev, minor changes have been made to processing CFLAGS, CXXFLAGS and LDFLAGS. Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes * ecasoundrc(5) - "default-output": new value "autodetect" (default) --- 5. Contributors Patches - Accepted code, documentation and build system changes Michael Ewe (2) -- bugfixes to ecasignalview and ECI C impl Mario Lang (1) -- section on ecasound.el to ECI Guide Eric Rzewnicki (1) -- set of updates to Ecasound User's Guide Kai Vehmanen (n/a) -- various Bug Hunting - Reports that led to bugfixes (items closed) Pierre Lorenzon (1) -- bugs in ecasound's daemon-mode protocol parser Jan Weil (1) -- cs-save dit not save preset parameters Feature suggestions - Ideas that led to new features (items) Jan Weil (2) -- map-ladspa-id-list command, -t:1 option --- 6.

[linux-audio-announce] [ANN] realtime-lsm-0.1.0 available via SourceForge

by Jack O'Quin

The first SourceForge release of realtime-lsm (0.1.0) now available. http://prdownloads.sourceforge.net/realtime-lsm/realtime-lsm-0.1.0.tar.gz?d… The Realtime Linux Security Module (LSM) is a loadable extension for Linux 2.6 kernels. It selectively grants realtime permissions to specific user groups or applications. There are only a few small differences between this release and the realtime-0.0.4 version released back in March. If that was working satisfactorily, there is no need to upgrade. The main purpose of this release is to take advantage of the services provided by SourceForge. (*) The module now declares the appropriate kernel vermagic string, thanks to a patch provided by Guenter Geiger. (*) Although the SourceForge project name is `realtime-lsm', the module it builds and installs is still called `realtime' and supports the same user interface. This LSM was written by Torben Hohn and Jack O'Quin, who make no warranty concerning the safety, security or even stability of your system when using it. But, if you do have problems, we would like to know about them via the SourceForge bug tracking system. -- joq

[linux-audio-announce] sfront 0.86 04/24/04 released

by John Lazzaro

Hi laa-folk, Announcing the release of sfront 0.86 4/24/04, available for download from: http://www.cs.berkeley.edu/~lazzaro/sa/index.html It's been a while since the last release -- I was waiting for the RTP MIDI specification to reach stability. This release supports the version of RTP MIDI described in draft-ietf-avt-rtp-midi-format-03.txt, which hopefully will be the version that goes to Last Call soon. See: http://www.cs.berkeley.edu/~lazzaro/sa/pubs/txt/current-rtp-midi.txt http://www.cs.berkeley.edu/~lazzaro/sa/pubs/txt/current-guide.txt For the latest in RTP documents. For those of you unfamiliar with sfront, here's a short bio: Sfront compiles MPEG 4 Structured Audio (MP4-SA) bitstreams into efficient C programs that generate audio when executed. MP4-SA is a standard for normative algorithmic sound, that combines an audio signal processing language (SAOL) with score languages (SASL, and the legacy MIDI File Format). Under Linux and Mac OS X, sfront supports real-time, low-latency audio input/output, local MIDI input from soundcards, and networked MIDI input using RTP and SIP. A SIP server hosted on the Berkeley campus manages sessions. The documentation includes a book about SAOL programming. --- John Lazzaro http://www.cs.berkeley.edu/~lazzaro lazzaro [at] cs [dot] berkeley [dot] edu ---

[linux-audio-announce] draft announcment

by Taybin Rutkin

JACK RELEASE 0.98.0 JACK is a low-latency audio server, written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin"). JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation. JACK is available at http://jackit.sf.net ***CHANGES*** Fixed bug when using non-dithered 16bit output. Fixed crashing bug with JACK clients that use SSE. three new functions in JACK API: int jack_client_name_size(void); int jack_port_name_size(void); int jack_port_type_size(void); These sizes are inclusive of the final NULL character. Automatic server startup (more on this below). Added OSS JACK driver. New option -m,--no-mlock: Do not attempt to lock memory, even if --realtime. New option -p,--port-max n: Set the maximum number of ports the JACK server can manage. The default value is 128. New option -T,--temporary: jackd will exit when last client disconnects. Configuration process reworked for better portability. This has helped jack run on MacOSX and FreeBSD. Added JACK thread initialization callback. ***AUTO START SERVER FUNCTIONALITY*** libjack will now try to automatically start jackd when jack_client_new() is called if it isn't already running. Because this changes the semantics of jack_client_new() and confuses certain apps, the new semantics apply if and only if $JACK_START_SERVER is defined and $JACK_NO_START_SERVER is not defined. This will change in future releases. libjack determines the proper arguments to pass to jackd by first checking ~/.jackdrc, failing that /etc/jackd.conf, failing that hardcoded strings that we've determined to be the most likely to work on a variety of platforms. The format of ~/.jackdrc and /etc/jackd.conf is as follows: absolute path to the jackd or jackstart binary to be executed, followed by the regular arguments all on one line. libjack will automatically insert the --temporary argument so that any auto started jack server will exit when the last client has disconnected. If libjack is unable to start the server, jack_client_new() will fail normally. We hope that this new functionality will make using JACK easier and more seamless with the JACK client. Taybin
