[LAA] New LV2 host implementation stack

by David Robillard

Hi all, I have released my new stack of libraries for implementing LV2 in hosts: * Serd http://drobilla.net/software/serd A fast, lightweight, dependency-free Turtle syntax library * Sord http://drobilla.net/software/sord An in-memory RDF quad store * Lilv http://drobilla.net/software/lilv An LV2 host library (replaces SLV2) * Suil http://drobilla.net/software/suil An LV2 UI loading/embedding library These libraries collectively replace SLV2, and have no dependencies except amongst themselves, and Glib (by Lilv and Sord, but this dependency will likely be removed in the near future). Serd and Sord replace Redland, making for a much smaller implementation more appropriate for audio software and embedded applications. Overall, Lilv is dramatically faster and leaner than SLV2, enough that the improvement should be quite noticeable from a user point of view (typically in a lag when the host first loads all LV2 data). Anyone using SLV2 is highly encouraged to migrate to Lilv. These libraries are well tested, each (except Suil) with a test suite covering over 90% of the code, which runs without memory errors or leaks. They are new, however, so (as always) there may be problems; feedback (at http://dev.drobilla.net/newticket or personally) is most welcome. More information available at the links mentioned above. For the lazy/eager, all downloads can be found in http://download.drobilla.net Peace, -dr P.S. Packagers, please read the PACKAGING file!

[LAA] Renoise 2.7 Final - Back To Beats

by Dac Chartrand

# FOR IMMEDIATE RELEASE: May 12th, 2011 - Eight weeks of community driven testing finish today. We are proud to announce that Renoise 2.7 is stable and ready for production. Thanks once again to our users, the best in the world. For the occasion we've teamed up with Puremagnetik.com to bring you "Puremagnetik XRNI Essentials Volume 1" - a hand-picked selection from their catalog of professionally multi-sampled instruments. This sample pack is free for all registered users, new and old. With over 500MB of sounds, producers can immediately jump into the latest sampling features of Renoise 2.7. From classic studio instruments like a Stratocaster and Mellotron to lo-fi digital chip sounds, "Puremagnetik XRNI Essentials Volume 1" offers something for everyone. As an added bonus this collection includes a pristinely sampled and programmed Yamaha Conservatory Grand Piano. The package contains: Analog Synth Basses, Circuit Bent Drum Kits, Buchla Drum Kits, Mellotron Strings and Flutes, Glitch, Toy & Lo-Fi Sounds, Fender Rhodes Mark II, Model-C Clavinet, Electric Guitar, Upright Bass, Classic Analog Synths, Grand Piano, and more. We're also pleased to announce an upgrade to our XRNX site and a Tool Update Downloader which automatically updates installed tools. It's so easy even your grandmother could do it. In fact, she's learning Lua and scripting a new controller template for Duplex as you read this. But I digress... # WHAT'S NEW SINCE 2.6? Renoise's internal instruments have been re-engineered. The focal point is a new keyzone editor that supports overlapping, velocity, and key release mappings. The Sample Keyzones editor brings with it user interface refinements, improved drumkit generation, better tuning options, new sample properties, and loop modes. Live instrumentalists can also tap into new realtime rendering modes and MIDI input routing, making Renoise on a laptop a formidable replacement for your old sampler. New Slice Markers push Renoise's breakbeat insanity one step further. With the click of a button, your break is sliced and keymapped. Amens away! More than just a beatslicer, creatives will soon discover custom offsets and the power of aliases for controlling longer recordings like vocals and soundscapes. The revamped Automation Editor now provides a zoomable overview of the entire song, as well as vastly improved envelope resolution. Navigating is smooth, dragging and drawing easier, so simple yet so useful. Internal FX get an injection of winning with a new Comb Filter and a Multiband Send that lets you surgically redirect a single sound source to 3 send tracks. New draggable gain and frequency handles in the native EQs add flavour and finesse to the tools. Other changes include improvements to DSSI, MIDI optimizations, hardware-compatible solo mode, adjustable audio headroom, pre-count, ameliorations to the Lua API, and numerous other changes in every aspect of the app; no stone was left unturned in this release. Full changelog with screenshots here: * http://www.renoise.com/new # MUSIC HACKDAY BERLIN: Renoise will be mentoring at Music Hack Day Berlin. The event takes place on the weekend of May 28th in the MTV Network offices located at the Spree river. Erik, dblue and Taktik will be on site to discuss Renoise, the Lua API, drink beer, and give out high fives. Check our community forums in the upcoming days for more details. # ABOUT RENOISE: Renoise is a sophisticated music sequencer and audio processing application for Windows, Macintosh, and Linux. It's a unique all-in-one music production environment for your personal computer. Renoise's rock-solid stability makes it ideal as a live jamming tool. You can map almost every part of the interface to a MIDI controller, run your guitar through a Line-In Device and distort it with native effects, or just use it as a drum machine; a sampler on steroids. Renoise's open API allows programmers to easily extend Renoise. With a few lines of code you can add the features or tools that you always wanted but never dared to ask for. Renoise is based on mod trackers. Mod trackers are characterized by displaying and editing music in an easily understood grid known as a pattern. These patterns are akin to sheet music, but are displayed alphanumerically instead of with musical notation. Renoise boasts full ReWire and Jack support, FX and instrument VST/AU/LADSPA/DSSI plug-in support, automatic plug-in delay compensation, multi-core load balancing, MIDI I/O, OpenSoundControl, audio recording, flexible audio output, graphical & numerical parameter automation, modular parameter routing, and much more. Due to its keyboard driven workflow, it makes the creation of desktop music far quicker than in a traditional MIDI-based sequencer. For experienced users, and those who don't necessarily want to be bound to piano roll systems to make music, it offers a refreshing approach to composing and is one of the most efficient ways to do so using a computer. Instead of spending hours cobbling beats together with a mouse, why not do it in seconds with just a few keystrokes in Renoise? Whether you're an audio veteran or just starting out, Renoise is a fantastic addition to any bedroom or professional studio. Got laptop? Use Renoise. # WEBSITE: * http://www.renoise.com

[LAA] [ANN] Ecasound 2.8.0 released

by Kai Vehmanen

1. Summary of changes in this release ------------------------------------- Important bugfix has been made to sample conversion routines. Many other minor bugs have been also fixed. 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 2.8.x series -------------------------- * The int-float conversion routines have been modified to be symmetric (previously asymmetric). As this impacts all use-cases involving fixed point audio, the release version was bumped to 2.8 to reflect the change. Ecasound now scales with 2^N for both int-to-float and float-to-int. For 0dBFS signals created in floating point domain, and normalized to [-1,1] range, the positive values are limited just before 0dbFS to avoid overflow (positive values exceeding 2^N-1). Pointers to how other projects handle this issue: - Case for symmetric conversions: http://lists.apple.com/archives/coreaudio-api/2009/Dec/msg00120.html - Blog entry to which the above is a response: http://blog.bjornroche.com/2009/12/int-float-int-its-jungle-out-there.html - libsndfile FAQ on the topic: http://www.mega-nerd.com/libsndfile/FAQ.html#Q010 - Discussion around the topic on JACK devel list: http://comments.gmane.org/gmane.comp.audio.jackit/20499 * Bugfixes to loop objects, jack_multi, JACK transport support, false runtime DBC warnings, seek support for -klg, ecasound-ruby hangs and ALSA output. Following bugtracker items closed: - http://sourceforge.net/tracker/?func=detail&aid=2013827&group_id=4605&atid=… * Signal handling has been simplified for not-so-POSIX platforms. For system/environments which do not provide all three of sigwait(), sigprocmask() and pthread_sigmask(), process will terminate immediately without the usual cleanup procedure upon receing a signal (SIGINT, TERM, et al). The old pause() based kludge has been removed from the codebase. For many, if not all, users this has no practical impact. * JACK transport is now disabled by default in batchmode. In interactive mode ('-c' option), the default is still 'sendrecv'. Ecasound now also provides better feedback about transport related events. Without graphical feedback, the interaction between JACK and Ecasound has been a common source of user confusion. For full list of changes, see git commit history. - http://www.eca.cx/ecasound/history.php 4. Interface and configuration file changes in 2.8 series --------------------------------------------------------- Default JACK transport mode is now "notransport" (do not send nor react to JACK transport state changes) when running in batchmode. Interactive mode (when started with '-c') still defaults to "sendrecv" as before. Note that the transport mode can always be explicitly set by passing '-G' option (see ecasound(1) man page for details). 5. Contributors to 2.8 series ----------------------------- Patches - Accepted code, documentation and build system changes ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Extracted with 'git-shortlog -s': v2.8.0: 1 Alessandro Ghedini 39 Kai Vehmanen Bug Hunting - Reports that led to bugfixes (items closed) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ v2.8.0 * Joel Roth (3) wrong sample type displayed for loop objects incorrect channel count for jack_multi objects -klg does maintain state across seeks * Julien Claassen (1) runtime DBC warnings * Dan Muresan, Sergei Steshenko (1) problems of asymmetry in int-float conversions * Alessandro Ghedini (1) signal handling bug caused problems to ecasound-ruby apps * Doug F. (1) incomplete playback to ALSA outputs Feature suggestions - Ideas that led to new features (items) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ None. 6.

[LAA] Audio-graphic Modeling and Interaction @ NIME 2011, May 29 2011

by Diemo Schwarz

Call for Participation: Audio-graphic Modeling and Interaction Workshop @ NIME 2011, Oslo, Norway Sunday, May 29: 1PM-4PM. This workshop focuses on recent advances and future prospects in audio-graphic scenes modeling and rendering. The convergence of the audio and graphic communities is fostered by the increase in computational resources, by cognitive studies on cross-modal perception, and by the industrial needs for realistic audio scenes. Audio-graphic research is spreading in areas such as games, architecture, urbanism, information visualization, or interactive artistic digital media. We will focus on the representation, the interaction, the rendering, and the perception of scenes in which the audio and graphical components are clearly identified and combined (in contrast to standard multimedia video streams). Registration to the workshop and NIME conference can be found here: http://www.nime2011.org/registration/ http://www.nime2011.org/pre-nime/tutorials/#Audio-graphic%20Modeling%20and%… Program ------- 1:00pm - 1:15pm Workshop introduction Roland Cahen, Hui Ding, Christian Jacquemin, Diemo Schwarz 1:15pm - 1:35pm Sound Level of Detail in Interactive Audio- graphic 3D Scenes Diemo Schwarz, Roland Cahen, Christian Jacquemin and Hui Ding 1:35pm - 1:55pm INScore An Environment for the Design of Live Music Scores D.
