On behalf of the guitarix team I'm proud to announce Guitarix Version 0.11.1 Bug fix release Guitarix is a simple Linux Rock Guitar amplifier and is designed to achieve nice thrash/metal/rock/blues guitar sounds. Guitarix uses the Jack Audio Connection Kit as its audio backend and brings to the jack audio graph a mono amplifier input/output port, and a FX mono input with two (stereo) output ports. Guitarix provides a jack midi input port to connect a midi controller (midi learn) and a (3 channel) jack midi output port, feed by a (scalable) mix of the tuner and a beat-detector. Release 0.11.1 comes with following changes : * fix Bug Echo/Chorus/Delay/Slooper don't work * add pre/post processing switch to all mono Effects We put the Guitarix widgets into a library, with the goal of making them usable independently from Guitarix. You can build it as shared library and there's a c++ (gtkmm) wrapper, a python wrapper and glade support. Check it out and look for examples in those directories, or just build a nice looking display with the glade editor, and of course ask in our Guitarix forum (it's still alpha). As a side note, Guitarix is now in debian(sid/squeeze/Experimental) , have fun _________________________________________________________________________ guitarix is licensed under the GPL.

[ANN] Ecasound 2.7.2 released

by Kai Vehmanen

1. Summary of changes in this release ------------------------------------- Manual gate feature has been added. Bugs have been fixed in saving chainsetup state, seeking with resample objects and with cygwin support. 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. Primary platform for running Ecasound is GNU/Linux. Ecasound can also be run on many UNIX-derived systems such as FreeBSD, Mac OS X and Solaris. Limited support for Windows is available through Cygwin. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. 3. Changes in 2.7.x series -------------------------- v2.7.2: * Manual gate (-gm) added. See ecasound(1) for docs. * liboil now enabled by default if its development files are found when running configure. * Bugfixes. v2.7.1: * Bugfixes. v2.7.0: * Open Sound Control (OSC) support. See the initial announcement mail sent to ecasound-list: http://eca.cx/ecasound-list/2009/04/0036-fixed.html Current interface is documented at: http://eca.cx/ecasound/Documentation/ecasound_osc_interface.txt The interface is still limited and subject to change in later releases, but it's a start. * New '-chorder' operator that allows to reorder channels of an audio stream. Also duplication and omission of certain channels is possible. See ecasound(1) man page for more information. * Added new amplify/gain variant '-eadb' that allows to specify the gain in dB. See the related mail thread: http://eca.cx/ecasound-list/2009/03/0034.html * Refactored POSIX signal handling in ecasound. See the following mail for some rationale, as well as a list of changes. See mail thread: http://eca.cx/ecasound-list/2009/02/0027.html * Various optimizations to Ecasound inner loops using the liboil library. See http://liboil.freedesktop.org/wiki/ To enable the optimizations, liboil-0.3 development files need to be installed and '--enable-liboil' must be passed to Ecasound's configure script. * New 'cop-get' interactive mode command. See the updated ecasound-iam(1) manual page for further info. Full list of changes is available at: - http://www.eca.cx/ecasound/history.php 4. Interface and configuration file changes in 2.7 series --------------------------------------------------------- v2.7.0: Output of '-ev' operator has been renewed. The name for default chainsetup created from command line is now "untitled-chainsetup". Most of the entries in the installed ecasoundrc file (in ${prefix}/share/ecasound/ecasoundrc), are now commented out by default. Major changes to the libecasound library public interface. This should not really affect anyone anymore, as direct use of libecasound has been discouraged for a long time and it is available only as a static library, but just in case someone is still using it. See libecasound/ChangeLog for a detailed list of changes. 5.

Rivendell 2.0.0beta0

by Fred Gleason

On behalf of the entire Rivendell development team, I'm pleased to announce the release of the first BETA snapshot of Rivendell 2.x, v2.0.0beta0. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License. Rivendell 2.x features many changes and improvements over the 1.x series, some of which are highlighted in the NEWS file, excerpted below: *** snip snip *** This is the initial BETA release of Rivendell 2.x. Some of the major changes over 1.x include: MPEG Capture/Playout. Rivendell can now be optionally compiled to support use of MPEG Layer 2 in the core storage library for all audio driver families (ALSA and JACK as well as AudioScience HPI). Web Services Architecture. Many internal services within Rivendell are now implemented via a web services API. Among other benefits, this approach allows these services to be easily accessed by third-party systems by means of the widely support HTTP protocol. Linux User Support. Any 'regular' user account can now access Rivendell; gone is the concept of a single 'Rivendell User' under which all Rivendell operations must occur. Replicators. Rivendell now sports a generic replication interface that can be used to create services to transport audio and other Rivendell data to/from external systems. Many other changes too numerous to list here have occurred as well; see the ChangeLog for details. For a concise summary of changes from the point of view of a system administrator looking to upgrade an existing Rivendell 1.x system to 2.x, see the file 'UPGRADING'. Database Update: This version of Rivendell uses database schema version 199, and will automatically upgrade any earlier versions. To see the current schema version prior to upgrade, see RDAdmin->SystemInfo. As always, be sure to run RDAdmin immediately after upgrading to allow any necessary changes to the database schema to be applied. Due to the complexity of the schema changes required for this update, the process may take significantly longer to execute than is commonly the case; users are cautioned to allow for ample time operationally. *** snip snip *** Please note that this is a BETA release; it is intended primarily for testing and verification. Do NOT put it on the air unless you understand precisely what you are doing. Further information, screenshots and download links are available at: http://www.rivendellaudio.org/ Cheers! |-------------------------------------------------------------------------| | Frederick F.

[ANN] Ceres V0.55 and jack_capture V0.9.54

by Kjetil S. Matheussen

Download from: http://archive.notam02.no/arkiv/src/?C=M;O=D Ceres ====== Ceres is a program for doing various sound effects in the frequency domain and displaying sonograms. The program has been developed for more than 15 years (probably), and is mainly made by Øyvind Hammer with contributions from Jonathan Lee, Stanko Juzbasic and many others. 0.48 -> 0.55: ------------- -Compiles on Ubuntu 10, Debian/SID and Fedora, both 32 bit and 64 bit OS. Huge thanks to Menno, Hermann Brummer, Dave Phillips and Ebrahim Mayat! -Various build improvements -Fixed a couple of crashes when playing. jack_capture ============ jack_capture is a program for recording soundfiles with jack. The default operation of the program is executed by writing "jack_capture" in the terminal without any extra command line options: $ jack_capture ...which will record what you hear in your loudspeakers into a stereo wav file. 0.40 -> 0.55: ------------- * Removed jack_capture_gui from the target list since it uses Xdialog, which again belongs to a package requiring gtk1. (This should make things simpler for package managers) * Made meterbridge optional during compilation. * Added the option --filename-prefix / -fp for setting the prefix for autogenerated filenames. The default is "jack_capture_". * Made jack_capture_gui2 use the -fp option to avoid overwriting files from older sessions. * Changed jack_capture_gui2 to use "-f ogg" instead of piping through oggenc. Did not do the same change for mp3 files, since liblame is not always available. * Added code to jack_capture_gui2 to create uniqe filenames when creating mp3 files. * Smaller fixes * Smaller reorganizing of buffer handling, disk handling and exit handling. * Only print warning if unable to set nice value less than 0. (-10 is okay now) * Added JackPortIsTerminal as jack port flag. * Various cleanups. * Let the jack process thread trigger the buffer check thread instead of using usleep. * Added the -jt option to let jack transport trigger when to start and stop recording. * Fixed possible bug when finishing the recording if user has specified a duration. * When allocating buffer, do not zero it out, only touch all pages belonging to it to make sure all memory is mapped into physical memory before it is used by the realtime process. This avoids hogging the memory bus unnecessarily. The first 8 blocks are still zeroed out during initialization though, for the CPU cache. (Might create a less shocking startup.) * Push back the '\n' character after reading it from stdin. For some unknown reason this seems to fix the occational problem of mixed up characters in the console when exiting. (if only ncurses worked in non-fullscreen mode...) * Only call sem_post if waiting. In extremely extreme situations, this avoids the sem value to overflow. Don't know what happens then. * Reduced chance of cache misses in the buffering scheme. * Replaced the two lockless fifo/lifo queues with three lockless ringbuffers. (CPUs without CAS2 instruction are now supported.) * Only increase buffer by two blocks at the time between soundcard interrupts. This should decrease the chance of jack_capture hogging the memory bus for too long. (Which in theory can lower the chance of xruns in memory intensive realtime processes.) * Changed buffering incrementing scheme. If, at any time, the amount of free buffer is smaller than the initial buffer size, increase the buffer a little bit. Only do this if the buffer is less than maxbuffer. Buffer is never decreased. * Replaced all posix pthread_cond variables with posix semaphores. Far simpler code and much easier to understand. * Increased default buffer time from 4 seconds to 8 seconds for mp3 files. * Fixed correct autogenerated file suffix for mp3 files. * Updated --advanced-help option and README file * Added missing link libraries to the makefile. Caused by Fedora not supporting indirect linking anymore. Patch from Orcan Ogetbil. (https://fedoraproject.org/wiki/UnderstandingDSOLinkChange) * Applied patch from Orcan Ogetbil to fix 64 bit PowerPC compilation.

spectmorph-0.1.0

by Stefan Westerfeld

spectmorph-0.1.0 has been released. This release allows distributing SpectMorph instruments (built from many sampled notes) as single file. Also support for playing instruments live was added, via the new JACK client or via BEAST plugin. The performance of the live decoder still needs to be improved, so right now polyphony is limited. Overview of Changes in spectmorph-0.1.0: ---------------------------------------- * file format changes - instruments based on more than one sample can be shipped as one single file - various performance optimizations - store data as little endian (since this is more likely to be the host endianness) - broken files or old files can be recognized and rejected * automated tuning algorithm (smextract auto-tune) * supported looping (for playing notes that are longer than the original sample) * added beast plugin for playing SpectMorph instruments * added jack client for playing SpectMorph instruments * added zero padding before start of a sample to get better initial frames * compile with -Wall * allow single file argument for smenc (output filename will be constructed with .sm extension) * support setting smplay decoder mode via command line parameter * refactoring, cleanups What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments. This should allow constructing hybrid sounds, for instance a sound between a trumpet and a flute. Also interpolating between two samples of the same instrument (different attack velocity of a piano) could be interesting. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 SpectMorph currently is still being developed, which means that it is not too interesting for end users, yet. Links: ------ Website: http://space.twc.de/~stefan/spectmorph.php Download: http://space.twc.de/~stefan/spectmorph/spectmorph-0.1.0.tar.bz2 There are sound examples on the website which demonstrate the sound quality of the current SpectMorph models using piano samples. -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

mudita24 1.03 -- improved envy24control mixer/router for ice1712-based sound-cards

by Niels Mayer

The "Mudita24" package is a modification of alsa-tools' envy24control: an application controlling the digital mixer, channel gains and other hardware settings for sound cards based on the ice1712 chipset ( http://alsa.cybermirror.org/manuals/icensemble/envy24.pdf ). It also displays a level meter for each input and output channel and maintains peak level indicators. This utility is preferable to alsamixer(1) for those with ice1712-based cards: M-Audio Delta 1010, Delta 1010LT, Delta DiO 2496, Delta 66, Delta 44, Delta 410 and Audiophile 2496. TerraTec EWS 88MT, EWS 88D, EWX 24/96, DMX 6Fire, Phase 88. Hoontech SoundTrack DSP 24, SoundTrack DSP 24 Value, SoundTrack DSP 24 Media 7.1. Event Electronics EZ8. Digigram VX442. Lionstracs, Mediastaton. Terrasoniq TS 88. Partial support for Roland/Edirol DA-2496. Now available, version 1.03: source: http://nielsmayer.com/envy24control/mudita24-1.0.3.tar.gz binary: http://nielsmayer.com/envy24control/mudita24-1.0.3.x86_64.tgz patch: http://nielsmayer.com/envy24control/mudita24-envy24control-0.6-to-1.0.3.pat… 'envy24control' is part of the "alsa-tools" package. For example, under CCRMA's Fedora repos, it's part of alsa-tools-1.0.22-1.1.fc12.ccrma.x86_64. This "mudita24" package updates/replaces the alsa-tools /usr/bin/envy24control application. The default "./configure ; make ; sudo make install" process on the source-code leaves a binary in /usr/local/bin/envy24control and places the man-page in /usr/local/man/man1/envy24control.1 . This means you can still use the standard alsa-tools version in /usr/bin/envy24control . Screenshots (controlling either Terratec DMX6Fire or M-Audio Delta 66): http://nielsmayer.com/envy24control/Mudita24-102-Monitor-Inputs.png http://nielsmayer.com/envy24control/Mudita24-102-Monitor-Outputs.png http://nielsmayer.com/envy24control/Mudita24-102-Patchbay+Router.png http://nielsmayer.com/envy24control/Mudita24-102-Hardware-Settings.png http://nielsmayer.com/envy24control/Mudita24-102-Analog-Volume.png http://nielsmayer.com/envy24control/Mudita24-102-About.png Changes since recent 1.0.0 and 1.0.1 releases: * Peak-meter display is in dBFS, corresponding to displayed dBFS peak-meter value and scale-widget dB labeling. * Hardware mixer input attenuators provide more precise control to the 0 to -48dB range of adjustment, turning the associated input "off" when the slider is moved to bottom of the scale. External MIDI control of the hardware mixer via --midichannel and --midienhanced options unaffected by this change. * For M-Audio Delta series, add display of "Delta IEC958 Input Status" under "Hardware Settings." * Command line options --no_scale_mark, --channel_group_modulus affect layout and presence of dB markings for sliders. --channel_group_modulus allows override of Left/Right grouping of dB labels for multichannel applications. * Control of peak-meter coloring via --lights_color and --bg_color options. Reasonable default colors used when these options are not set. (1.0.1's use of Gtk skin to provide an automatic color choice didn't work out that well on some systems.) * Fixed command-line options --card and --device to allow valid ALSA card and CTL device names ( https://bugzilla.redhat.com/show_bug.cgi?id=602900 ). * Profiles created in ~/.envy24control and not "~/envy24control" ( http://bugtrack.alsa-project.org/alsa-bug/view.php?id=4738 ). Summary of previous updates from envy24control 0.6.0 (GIT HEAD) to "1.0.3": (1) Implemented "Peak Hold" functionality in meters; reimplemented meters to do away with inefficient "faux LED" peak-meter display. (2) Significantly reduced the number of timer interrupts generated by this program by slowing down all updates to 10 per second -- previously meters updated 25x/second! (3) All volumes are represented as decibels, including the 0 to -48dB range of the hardware peak-meters, the 0 -to- -48dB&off attenuation for all inputs to the digital mixer, the 0 -to- -63dB attenuation of the analog DAC, and the +18 -to- -63dB attenuation/amplification of the analog ADC. (4) All gtk "scale" widgets have dB legends; the "PageUp" "PageDown" keys allow rapid movement between the marked levels, and "UpArrow" and "DownArrow" allow fine-adjustment. -- Niels Mayer http://nielsmayer.com PS: Why "mudita24" ? An alternate name to avoid confusion with "envy24control 0.6.0" until changes in this version propagate upstream. See http://en.wikipedia.org/wiki/Envy#In_philosophy "In Buddhism the third of the four divine abidings is mudita, taking joy in the good fortune of another. This virtue is considered the antidote to envy and the opposite of schadenfreude."

LinuxMusicians Monthly Round-Up #1 - August 2010

by Jeremy Jongepier

Dear all, I've started a new initiative under the umbrella of LinuxMusicians, namely publishing an editorial on Linux audio developments and Linux audio related news. My goal is to publish an editorial at the beginning of each month to cover what happened in the month before. The first editorial covering the month July is finished and published: http://linuxmusicians.autostatic.com/2010/08/05/editorial-august-2010 I'd really appreciate any feedback, remarks etc. and any input for the next edition is more than welcome. This time I mainly focused on the releases of new versions of apps and new projects. From now on I want to keep track of that so I can elaborate more on the news part. Best, Jeremy
