SpectMorph 1.0.0-beta1 has been released. The main changes are: - WavSource: added formant preserving algorithms for repitching vocals - KeyTrack: new operator to combine instruments by note range - Envelope: new operator to generate arbitrary modulation envelopes - LFO: support arbitrary user defined curves There is a tutorial on YouTube for the new features: - https://www.youtube.com/embed/mwVUsuOTcN0 Feedback for any issues you might experience with the beta version is appreciated. What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 2.1 or later Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS (Intel and Apple Silicon), with CLAP/LV2/VST plugins. Under Linux, there is also JACK Support. Links: ------ Website: https://www.spectmorph.org Download: https://www.spectmorph.org/downloads There are many audio demos on the website, which demonstrate morphing between instruments. List of Changes in SpectMorph 1.0.0-beta1: ------------------------------------------ #### New Features * WavSource: support two formant preserving algorithms for repitching vocals. * New operators: - KeyTrack - can be used to combine instruments by note range. - Envelope - to generate arbitary modulation envelopes. * User defined curve editor for KeyTrack, Envelope and LFO. * Add presets using the new operators: - KeyTrack Choir Ah/Oh - StringBrass Fusion * JACK CC values are now interpreted per channel (allows polyphonic modulation). * Support double click to reset properties to default value. #### Fixes * Apply midi channel bend to new voices. * Make portamento affect filter cutoff key tracking. * Fix problems with WavSource paths stored by LV2 plugin (make Ardour archives work). * Fix getting the initial click events / focus plugin UI on macOS under Bitwig. * Fix invalid access to past last vector element (#24). * Make PandaResampler work without problems in ASAN builds. * Refactor leak debugger to fix possible crashes caused by global destructors. * Do not ship sample data in "1 Instrument WavSource" preset. #### Internals: Improvements * Generate and store spectral envelopes in each AudioBlock for formant correction. * Improve the strategy for portamento synthesis (more accurate and less CPU usage). * Propagate portamento frequency to sources. * Randomize start phase per default to improve "Harmonic Resynthesis" quality. * JACK: use two audio outputs to be able to implement stereo support later on. * Add fast vectorizable log2 approximation (based on Tims version from Anklang). * Phases in LiveDecoder, IFFTSynth: change from float to uint for performance reasons. * Various minor performance optimizations. * Minor LV2 meta data updates (port groups, avoid port resizing extension). * Use newer compilers: g++-14 for windows, g++-13 for static linux plugins. * Support automatically downloading instruments from configure. * Avoid using std::mutex in hard RT code. #### Internals: Minor Changes * Refactoring: - Deduplicate morphing code from MorphGrid and MorphLinear. - Use shared pointers for GenericIn/GenericOut classes (RAII). - Get rid of `sm_clamp` / `sm_bound` (-> std::clamp). * Improve CI support (use debug-cxx, asan, ubsan, test static build, avoid fftw planning). * Add post install test which tests audio output for all presets after installation. * Validate LV2 feature arrays. * Support user defined scripts in testmidisynth test. * Improve error messages for preset loader. * Build cleanups: remove libbse code, simplify Qt build (remove smsampleedit). * Update CLAP version to 1.2.1. -- Stefan Westerfeld, http://space.twc.de/~stefan

Hi all, it's finally here, Qtractor 1.0.0 (the unthinkable) is released! Change-log: - Making up the unthinkable (aka. v1.0.0) - General plugin scan/cache optimization. - Improved legibility to all clip title labels (color contrast). - Save/load the correct order and labeling of audio/MIDI send/return pseudo-plugin inserts. - Fixed a display and port-name filtering issue that was present ever since on the Connections widget. 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.

PandaResampler 0.2.0

by Stefan Westerfeld

PandaResampler 0.2.0 has been released. This is a header only library for C++ which implements fast factor 2, 4 or 8 upsampling and downsampling based on SSE instructions. I've developed the code for my DSP code in Anklang and SpectMorph. It might be useful for you if you have some DSP loop which needs to be oversampled to avoid aliasing. https://github.com/swesterfeld/pandaresampler -- Stefan Westerfeld, http://space.twc.de/~stefan

Ratatouille.lv2 v0.4 released

by Hermann Meyer

Ratatouille is a Neural Model loader and mixer. It 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. A "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. Settings could be saved as presets (host side) and switched seamless. You'll find ready to use binary packages on the release page.
