The Aqualung music player had its 2.0 release earlier this week. This new major release comes a solid decade after the preceding one (Aqualung 1.0 was released in 2015). Changes to the player’s core functions are minimal: just a handful of fixes, more or less. The most substantial change, also the main motivation for touching Aqualung after so many years, is migrating the UI from GTK2 to GTK3.

Ratatouille.lv2 v0.9.6 released

by Hermann Meyer

Ratatouille is a Neural Model loader and mixer for Linux/Windows. This release implement a little ramp on Model file switching to avoid pops or clicks. Also provide binaries for older CPU's on windows. Ratatouille allow to load up to two neural model files and mix there output. Those models could be *.nam files <https://tonehunt.org/all> or *.json or .aidax files <https://cloud.aida-x.cc/all>. So you could blend from clean to crunch for example, or, go wild and mix different amp models, or mix a amp with a pedal simulation. Ratatouille using parallel processing to process the second neural model and the second IR-File to reduce the dsp load. The "Delay" control could add a small delay to the second model to overcome phasing issues, or to add some color/reverb to the sound. To round up the sound it allow to load up to two Impulse Response files and mix there output as well. You could try the wildest combinations, or, be conservative and load just your single preferred IR-File. Each neural model may have a different expected Sample Rate, Ratatouille will resample the buffer to match that. Impulse Response Files will be resampled on the fly to match the session Sample Rate.

Release aloop v0.3

by Hermann Meyer

aloop is a audio file looper for Linux using PortAudio as backend (jack, pulse, alsa), libsndfile to load sound files and zita-resampler to resample the files when needed. The GUI is created with libxputty. aloop 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 * endless looping * break playback (keyboard support space bar) * reset play-head to start position (keyboard support courser left) This release add support for drag and drop indicator inside the playlist. It may as well fix some small bugs, or, maybe introduce new ones. 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/v0.3

ImpulseLoader.lv2 v0.4 released

by Hermann Meyer

ImpulseLoader is a simple, mono, IR-File loader/convolution LV2 plug for Linux and windows. This release fix issues with arbitrary buffer sizes. IR-Files could be loaded via the integrated File Browser, or, when supported by the host, via drag and drop. A pop up menu provide quick access to all IR Files in the current loaded Path. If the IR-File have more then 1 channel, only the first channel will be used. IR-Files will be resampled on the fly to match the session Sample Rate.

Qtractor 1.5.3 - A Mid-Winter'25 Release

by Rui Nuno Capela

Hi all, Qtractor 1.5.3 (mid-winter'25) is out! Change-log: - MIDI clip editor (aka. piano-roll): mouse cursor pointer shape now follows the current edit/draw mode permanently. - Attempt to improve MIDI SPP accuracy by postponing MIDI Continue command in one 16th note at playback (re)start. - Specific to (lib)RubberBand time-stretching and pitch-shifting, formant preserve and finer (R3) engine processing are now added to audio clip/playback options. - Resume normal playback state if rolling when transport rewind or fast-forward is disengaged. - Custom Style Sheet files (*.qss): all url() paths are considered relative to style-sheet file location. - Enforce a fixed size when LV2 plug-in UI no-user-resize feature is explicitly requested.) 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.

Brickworks 1.3.0 released

by Stefano D'Angelo

Hi all! We are glad to announce that we released version 1.3.0 of Brickworks, the music DSP toolkit that supplies you with the fundamental building blocks for creating and enhancing audio engines on any platform. Here's a short list of changes: * Introduced fast time-invariant TDF-II IIR filters of first and second order (biquads) and new related examples. * Now C++ API/implementations use BW_NULL instead of nullptr to support ancient C++ compilers. * Improved build system for examples and updated related documentation. * Fixed several small documentation typos. Consequently, we also updated Brickworks Pro algorithms to take advantage of the latest improvements. Brickworks is fully free/open source software (GPLv3 license) and we also offer commercial licenses. You can find more information on the official web page: https://www.orastron.com/algorithms#brickworks. Best regards, Stefano D'Angelo Orastron - https://www.orastron.com/

Call for LAC Reviewers

by Romain Michon

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!
