[LAA] Linux Audio Conference 2015 - Call for Participation

by Albert Graef

[Sorry for cross-posting, please distribute.] Linux Audio Conference 2015 - Call for Participation (Due to exceptional circumstances, this announcement comes a bit late, so please note the early deadline of Feb 1st for submissions. We apologize.) We are happy to announce the next issue of the Linux Audio Conference (LAC), April 9-12, 2015 @ JGU | Johannes Gutenberg University, in Mainz, Germany. http://lac.linuxaudio.org/2015/ The Linux Audio Conference is an international conference that brings together musicians, sound artists, software developers and researchers, working with Linux as an open, stable, professional platform for audio and media research and music production. LAC includes paper sessions, workshops, and a diverse program of electronic music. *Call for Papers, Workshops, Music and Installations* We invite submissions of papers addressing all areas of audio processing and media creation based on Linux and other open source software. Papers can focus on technical, artistic and scientific issues and should target developers or users. In our call for music, we are looking for works that have been produced or composed entirely/mostly using Linux and other open source music software. The online submission of papers, workshops, music and installations is now open at http://lac.linuxaudio.org/2015/participation The deadline for all submissions is Feb 1st, 2015 (23:59 HAST). You are invited to register for participation on our conference website. There you will find up-to-date instructions, as well as important information about dates, travel, lodging, and so on. This year's conference is hosted by the Computer Music Research Group (Bereich Musikinformatik) at the IKM (Institut für Kunstgeschichte und Musikwissenschaft) of the Johannes Gutenberg University (JGU) at Mainz. Being founded in 1991, our research group has been among the first German academic institutions in this interdisciplinary field at the intersection of music, mathematics, computer science and media technology. In our media lab students are working almost exclusively with Linux, and in our research we are also devoted to contributing to the growing body of open source audio and computer music software. http://www.musikwissenschaft.uni-mainz.de/Musikinformatik/ We look forward to your submissions and hope to meet you in Mainz in April! Sincerely, The LAC 2015 Organizing Team -- Dr. Albert Gr"af Computer Music Research Group, JGU Mainz, Germany Email: aggraef(a)gmail.com WWW: https://plus.google.com/+AlbertGraef

[LAA] MIDI Trigger LV2 plug-in announce

by Viacheslav Lotsmanov

We released our plug-in which sends MIDI notes by audio peaks under GNU/GPLv3. It has one audio input port and one MIDI output port. It works like trigger-sampler, but more unix-way (without sampler). You just send output MIDI note to sampler that you love. You can save dynamic of your audio signal, just use velocity controls. About "Note-off mode" control you can read here: https://github.com/metachronica/audio-dsp-midi-trigger/blob/6992e837f8cdce1… We'll document it in the future more user-friendly. https://github.com/metachronica/audio-dsp-midi-trigger First release here: https://github.com/metachronica/audio-dsp-midi-trigger/releases/tag/v0.0.1

[LAA] LSA 0.1.0

by Mark Karpov

I would like to announce LSA (LiSt properties of Audio files). This is a minimal, lightweight, console, Unix-style program to list various parameters of audio files. 'Unix-style' means that it tries to do one thing and do it well. LSA also tries to be fast. It has been written in C, it's multithreading (creates one thread per physical core), it uses SSE and SSE2 intrinsics (some people are still using some AMD processors that have no support for SSE4). If you ever have to wait for results, it's because of hard drive speed or decompression. Decompression is performed by Audio File library, so I cannot easily speed up this. LSA is built on top of Audio File library, so it inherits its list of supported file formats: * AIFF/AIFF-C (.aiff, .aifc) * WAVE (.wav) * NeXT .snd/Sun .au (.snd, .au) * Berkeley/IRCAM/CARL Sound File (.sf) * Audio Visual Research (.avr) * Amiga IFF/8SVX (.iff) * Sample Vision (.smp) * Creative Voice File (.voc) * NIST SPHERE (.wav) * Core Audio Format (.caf) * FLAC (.flac) Supported compression formats: * G.711 mu-law and A-law * IMA ADPCM * Microsoft ADPCM * FLAC * ALAC (Apple Lossless Audio Codec) The program currently is capable to display the following parameters: * sample rate; * sample width; * sample format (signed or unsigned integer, single or double precision floating point); * number of channels; * length in minutes, seconds, and hours (if necessary) per file; * total length of all files in actual directory; * number of frames per file; * total number of frames of all files in actual directory; * peak [0..1] per file; * maximum peak among all files in actual directory; * compression scheme. TODO: * efficiently calculate perceived loudness (as per ITU-R BS.1770-3); * efficiently calculate loudness range. LSA repository is here: https://github.com/mrkkrp/lsa Documentation: LSA comes with its own man page License: GNU GPL

[LAA] CLAP, new virtual instrument and effect plugin interface proposal

by Alexandre Bique

Hi, I worked on a new plugin interface, it is not yet finished and set in stone, but ready enough to gather initial feedback and advice. The specification is hosted on github: https://github.com/free-audio/clap and is available under the MIT license. There is a generated specification document at: http://free-audio.github.io/clap/ I hope that you'll find it interesting and give it a chance. Thanks. Regards, -- Alexandre Bique

[LAA] MIDA 0.3.0

by Mark Karpov

I would like to announce MIDA, version 0.3.0. Short description: MIDA is a minimalistic language for algorithmic generation of MIDI files. MIDA is not interactive in sense that you cannot control result of its activity in real time, it is intended for producers and should be used with a DAW. MIDA can help you create variative elements in your music in a very simple way. Since MIDI can control a lot of different instruments, power of MIDA is truly great. Main reason for MIDA development is to create software tool that can be used in such a way that does not change established workflow, so people could use familiar plugins and software instruments. Unlike many programs in field of algorithmic composition, MIDA does not aim creating complex or peculiar algorithms, because complexity of such systems rarely translates into emotional impact directly. Instead, MIDA gives you simple and effective tool to vary parameters of MIDI events. MIDA does not have GUI, because it doesn't need one. It can work as REPL (interactive mode) or as translator from source to MIDI files (batch mode). MIDA repository is here: https://github.com/mrkkrp/mida Documentation online: http://mrkkrp.github.io/mida/ Although MIDA is created on GNU/Linux and for GNU/Linux, it can be compiled on many platforms (but only Windows version is tested). MIDA is licensed under GNU GPL version 3, it's free software. Regards, -- Mark Karpov

[LAA] Yoshimi V 1.3.0

by Will Godfrey

There it is, all shiny and bright :) http://sourceforge.net/projects/yoshimi We have the usual crop of optimisations and (fewer) bugfixes. There are further improvements to the GUI, including significant layout changes. The most involved change has been the introduction of LV2 support - as our most intrepid friends will know :) This has been extensively tested on four completely different LV2 hosts, along with detailed tests of Yoshimi in stand-alone mode to ensure there are no regressions. Supported features: 1. Sample-accurate midi timing. 2. State save/restore support via LV2_State_Interface. 3. Working UI support via LV2_External_UI_Widget. 4. Programs interface support via LV2_Programs_Interface. Planned features: 1. Multi channel audio output. Now only 'outl' and 'outr' are routed to lv2 plugin instance. 2. Controls automation support. This will be a part of a common controls interface. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.
