SpectMorph 1.0.0-beta2 has been released. Compared to beta1, the only change is that the plugin user interface now works properly on macOS 14. You can get the new version from https://www.spectmorph.org/downloads If you do not use macOS 14, there is no reason to update. Changes in beta2: ----------------- * Plugin user interface now works correctly on macOS 14 (#28). * Update clang++ compiler version on macOS. * Minimum supported macOS version is now macOS 11. Feedback for any issues you might experience with the beta version is appreciated. -- Stefan Westerfeld, http://space.twc.de/~stefan

retuning examples

by Fons Adriaensen

Hello all, I'm still working on a new autotuner, zita-at2. Some examples can be checked here: <http://kokkinizita.linuxaudio.org/linuxaudio/retune/> There's no autotune in these, just fixed pitch or formant shifts - they can now be controlled separately. Comments welcome, and of course I still need some more vocal tracks to test... Ciao, -- FA

SpectMorph 1.0.0-beta1

by Stefan Westerfeld

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

[ANN] Qtractor 1.0.0 - An Unthinkable Release batch #3

by Rui Nuno Capela

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.

Upgrading pipewire

by Alf Haakon Pietruszka Lund

Hello list! I'm currently testing Linux Mint Debian Edition (LMDE) 6 "Faye" to see how pipewire performs. However, the first stumbling stone is that LMDE 6 ships with pipewire 0.3.65. It does have backports enabled though, where version 1.0.7 is available, but I can't understad how to upgrade. This is what I tried: 1. Open synaptic and search for all pipewire packages with version 0.3.65. 2. Mark all the packages to use version 1.0.7 (Package > Force version...). Synaptic then automatically marks some other packages for upgrading or removal. 3. Despair at the error message E: Unable to correct problems, you have held broken packages. E: Unable to correct dependencies Anyone here had a go at this before, or have pointers on how to succesfully upgrade? Best regards, Alf
