Hi everyone, As we're getting ready for LAC 2025, we're currently looking for potential reviewers for the scientific track of the conference. In fact, and to be completely transparent about this, it turns out that the "historial list of LAC reviewers" has been lost after "all these years without LAC." After the paper submission deadline (March 24) will be passed, reviewers will have until April 18 to write their reviews. We hope to be able to assign no more than three papers to each reviewer. Whether you already reviewed for LAC or not, we kindly ask you to fill out this form: https://framaforms.org/reviewer-call-for-lac-25-1738313198 to apply to be a reviewer. Filling out this form doesn't guaranty that you will review for LAC: your application will be reviewed by the scientific committee of the conference who will shortly let you know if it has been accepted or not. We thank you in advance for your help with that! As a side note, we remind you (again) that the paper submission deadline for LAC 2025 is March 24: https://jimlac25.inria.fr/lac/#important-dates We look forward to seeing you in Lyon in June! Cheers, Romain Michon (for the LAC 2025 organizational committee) ps: feel free to forward this message to any group/individual/platform who might be able to help with this!

by Hermann Meyer

aloop is a audio file looper for Linux using PortAudio as back-end (jack, pulse, alsa), libsndfile to load sound files and zita-resampler to resample the files when needed. The GUI is created with libxputty. This is the first release for aloop, it comes with the following features: * support all file formats supported by libsndfile. * resample files on load to match session Sample Rate * file loading by drag n' drop * included file browser * open file directly in a desktop file browser * open file on command-line * create, sort, save and load playlists * select to loop over a single file or over the play list * move play-head to mouse position in wave view * set loop points for start/end loop * save loop points in play list * save selected loop as wav file * play backwards * volume control * break playback (keyboard support space bar) * reset play-head to start position (keyboard support courser left) Dependencies * libsndfile1-dev * portaudio19-dev * libcairo2-dev * libx11-dev Project page: https://github.com/brummer10/aloop Release Page: https://github.com/brummer10/aloop/releases/tag/v0.1 Please report issues to the project issue tracker.

Qtractor 1.5.2 - A New-Year'25 Release

by Rui Nuno Capela

Greetings, Qtractor 1.5.2 (new-year'25) released! Change-log: - Duplex MIDI Clock mode is not allowed anymore. - Immediate and consecutive plugin parameter changes are now merged into a single undo-able command, reflecting only the first value change in the series, dropping the previous old algorithm, which was dead wrong if not utterly defective. - Unique track names resolve to the first line only. - Help/Shortcuts... Search tool gets implemented; all changed MIDI controller shortcuts are reverted to their previous settings, when discarding or dismissing the dialog. - Fixed missing MIDI SPP in some cases. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Vee One Suite 1.3.0 - A New-Year'25 Release

by Rui Nuno Capela

Greetings, The 'Vee One Suite', the 'gang-of-four' 'old-school' software instruments, * synthv1 [1] as a polyphonic subtractive synthesizer; * samplv1 [2] a polyphonic sampler synthesizer; * drumkv1 [3] as yet another drum-kit sampler; * padthv1 [4] a polyphonic additive synthesizer. Are here released for the New-Year'25 recycle... All still delivered in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non/New Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Change-log: - Just another Vee-One's release for the New Year... - Last current element is now preserved and selected on preset and/or LV2 plug-in load (host permiting). (drumkv1 [3] only) - LV2 Plug-in: element parameters as legacy input control ports are not automatable nor addressable from the host anymore. (drumkv1 [3] only) - LV2 Plug-in: avoid making offset and loop range changes as regular parameter updates, which marked the host's state dirty (modified). (applies to samplv1 [2] and drumkv1 [3] only) The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 1.3.0 (new-year'25) released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

Hi again, Qtractor 1.5.1 (end-of-year'24) is out!

Drumstick Multiplatform MIDI File Player 1.7.5 Released

by Pedro Lopez-Cabanillas

Drumstick (https://drumstick.sourceforge.io/docs/index.html) is a set of GPLv3 licensed C++/Qt libraries for MIDI applications. The project includes several tools as examples, and among them is the drumstick-guiplayer utility that leverages the Drumstick::ALSA library, so it is available only for Linux (because the ALSA sequencer is a linux only technology). Some people have requested a program with the same functionalities also on Windows and macOS, so here it is. But this project is much more ... Some key features: * MIDI Output to hardware MIDI ports, or any other Drumstick backends, like soft synths * Transpose song tonality between -12 and +12 semitones * Change MIDI volume level (using MIDI CC7) * Scale song speed between half and double tempo * Supports MID/KAR/RMI (Standard MIDI Files) and WRK (Cakewalk) file formats Changes in v1.7.5: * fix for GH ticket #32: text highlight color setting * fix for Backend manager * building and packaging with msvc 2022 on Windows, including ARM64 arch * using Drumstick 2.10, including better Fluidsynth settings Build requirements: * C++11 compiler * Qt5 >= 5.15 or Qt6 >= 6.2 * Drumstick libraries v2.10 * Uchardet v0.0.8 * CMake 3.16 * Pandoc (when BUILD_DOCS=on) Copyright (C) 2021-2024 Pedro Lopez-Cabanillas License: GPL v3 or later Project and Source Repositories https://sourceforge.net/p/dmidiplayer https://github.com/pedrolcl/dmidiplayer Downloads https://sourceforge.net/projects/dmidiplayer/files/v1.7.5/

audiowmark-0.6.3 - Audio Watermarking

by Stefan Westerfeld

Hi! audiowmark-0.6.3 is now available at https://uplex.de/audiowmark Overview of Changes in audiowmark-0.6.3: * update HLS support to build with ffmpeg-7 API (#68) * preserve wav subformat (#64) - write float/double wav output for wav float/double input - write signed 16, 24 and 32 bit wav output for 16, 24, 32 bit wav input - added test that wav subformat format is preserved (make check) * improved RawConverter: - support float/double input/output (very fast on little endian systems) - fix bug for unsigned integer raw input/output (16, 24 and 32 bit) - better tests (make check) - faster 16/32 bit conversion on little endian systems * add format wav-pipe for very long input/output streams on stdin/stdout * performance optimizations for SFOutputStream * add documentation for Windows/Cygwin builds (#45) audiowmark is an open source solution (GPL3 or later) for watermarking audio files. It has many features, it is robust, fast, secure and of course we believe that the watermark is not audible for most users. The project page provides the documentation and source code as well as some audio demos, so you can check whether you hear a difference between original and watermarked files. Cu...

Virtual MIDI Piano Keyboard 0.9.1 Released

by Pedro Lopez-Cabanillas

Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player. Changes in v0.9.1: * Fixed Qt style preferences ignored * Add FR azerty keymap. Thanks to Bruno Duyé * Fix for GH ticket #27: Enable F10 key in Windows when using native filters * Merge pull request #26 from RoboSchmied: fix 2 typo * building with msvc 2022 on Windows * Requires: drumstick v2.10. Compilation minimum requirements for all platforms: * CMake 3.16 * C++17 compiler * Qt6 >= 6.2 or Qt5 >= 5.9 * Drumstick 2.10 Please use the mailing list <vmpk-devel(a)lists.sourceforge.net> for questions and comments.
