Hi I revisited a old guitarix project (SpecMatch) and ported it to python3. SpecMatch aims to compare two Sounds and generate a Impulse Response File from the different. Intentional it was developed to easier the process to recreate a specific Sound within guitarix. Now, this day's while we've NAM and AIDAX, there are better way's to do so. Hence I've u-bounded it from guitarix and makes it a tool on it's own, as there are still the need to add convolution to get the expected sound. SpecMatch allow to load two Sound files, compare the Frequency spectrum's of them, and generate a Impulse Response File from the difference. So it enable you to get the missing bits. A other use-case is to archive the "Full Impulse Response" of a destination file by using the usual NAM trainer input file as source file in SpecMatch. I've posted some of my results, using it this way, as a show case, on the linuxmusicians forum her: https://linuxmusicians.com/viewtopic.php?p=168587#p168587 This is, after all the years, still work in progress, and, there shouldn't ever been a release to be expected, as it is plain development. Anyway, if this stuff is of some interest for you, here it is: https://github.com/brummer10/SpecMatch regards hermann

[LAD] PandaResampler 0.2.1

by Stefan Westerfeld

PandaResampler 0.2.1 has been released. https://github.com/swesterfeld/pandaresampler 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. Changes in PandaResampler 0.2.1: -------------------------------- * Use meson build system. * Improve test coverage and CI tests. * Support building a shared library (#3). * Do not build tests unless -Ddevel=true is used (#2). * Install headers to include install directory from meson (#1). -- Stefan Westerfeld, http://space.twc.de/~stefan

[LAD] 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

[LAD] ANN: WebPdL2Ork

by Ivica Ico Bukvic

Please pardon cross-posting. I would appreciate it if you would please spread the word. Thank you. Dear all, After years of development, the Pd-L2Ork developer community is thrilled to announce immediate availability of the *WebPdL2Ork* open *BETA* that is capable of running just about any patch created using Pd-L2Ork inside a browser. Simply upload your patch to a Web-accessible location and point your browser to *http://pd-l2ork.music.vt.edu:3000?url=<URL-to-your-patch> <http://pd-l2ork.music.vt.edu:3000/?url=%3CURL-to-your-patch%3E>* All related subpatches and abstractions will be accessible as long as they are in the path. The main patch will be stretched across the browser window. Subpatches may be visible as floating windows as long as their location has been saved within the box of the original patch. Some adjustments may be necessary to the subpatch locations, or they can be even embedded as graph-on-parent-enabled subpatches on the main patch window. To test out patches already hosted on our page, please use links provided below. Select patches also have hidden shortcuts outlined below. For optimal experience, we recommend Google Chrome <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.googl…> or Chromium <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.chrom…> . VT Waves Project Learning Modules: - Autotune <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fl2ork.mus…> (explore how an Adelle solo refrain would sound if sung on a single note;) - Distortion <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fl2ork.mus…> (experiment with clipping an audio signal to create a guitar-like distortion) - Phase Cancellation <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fl2ork.mus…> (learn how to cancel vocals from just about any mainstream pop tune by subtracting the right channel from the left with an inverted phase, use Shift+(1-3) to enable different sources) - Pitch Relationships <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fl2ork.mus…> (explore frequency and pitch relationships; use Shift+A to enable pitch/frequency ratio viewer, and Shift+S to open spectrogram subpatch) - Spectral Filtering <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fl2ork.mus…> (the iconic Forbidden Planet and FFT-based vocal filtering) - Spectral Filtering Harmonics <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fl2ork.mus…> (explore decomposition and reconstruction of human voice into 10 sine tones; use keys ~ and 1-0 to toggle individual overtones, use Shift+(2-3) to enable other potential sound sources, toggle off a source to "pause" the signal, use Shift+4 to toggle slider that cross-fades betwen the original signal and reconstructed one) And, if you have a beefy computer, you can also run the entire L2Ork Tweeter <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fl2ork.mus…> inside the browser (currently networking is not supported, so only the offline mode is available). Once loaded, consider opening one of the included saved sessions using the top-right corner session loading option by clicking on the green "LOAD" button positioned immediately to the left of the text box. Please be patient with the loading process, as this is a CPU intensive patch (the pd-l2ork patch itself is more than 5MB). Once the session is loaded, it may take up to 10 seconds for the audio engine to catch-up before the audio dropouts stop. If dropouts do not stop, or if loading takes much longer, chances are your CPU is not fast enough to handle the patch running inside the browser (you can always explore the desktop version which is considerably less CPU intensive). Use Shift+(F1-F12) to take control of individual parts. For more info on L2Ork Tweeter, including tutorial videos, visit our Tweeter <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fl2ork.mus…> page. *What does not work:* Gem library, networking objects (they load but do not work due to sandboxed nature of a web browser) and a few select (and not commonly used) 3rd-party libraries are not yet supported. Everything else should work out-of-box. *To learn how to build your own HTTPS-enabled web server:* Visit the pd-l2ork github <https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.co…> and read the emscripten/DOCUMENTATION.md file.

[LAD] 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

[LAD] [Announce] FFADO version 2.4.9

by Jonathan Woithe

The FFADO project (https://ffado.org) announces the availability of FFADO version 2.4.9. This is a maintenance release which contains minor improvements. This is a source-only release that can be downloaded from https://ffado.org/files/libffado-2.4.9.tgz Changes since FFADO 2.4.8: * Support compilation against musl libc. Thanks to Alyssa Ross. * Remove build-time checks for utilities that are not used (pyuic). * Install the ffado-mixer appdata file only if ffado-mixer has been built. Thanks to Jan Tojnar for the suggestion. * Add a DATADIR option to scons and use it in line with GNU conventions. Thanks to Jan Tojnar for the suggestion and the patch. * Update the AppStream document with more complete information and in line with current best practice (Jan Tojnar). * Rename XDG files to match modern standards (Jan Tojnar). * Install XDG files manually to simplify the build script and avoid depending on xdg-utils (Jan Tojnar). Thanks to those who have helped with this release, including Alyssa Ross and Jan Tojnar. Notes for packagers: * A consequence of the DATADIR support is that the default MANDIR has shifted from `${PREFIX}/man/` to `${PREFIX}/share/man/`. The latter is arguably more common, but if the original path must remain in use it is still possible to manually set MANDIR at build time. * The presence of the DATADIR option may allow simplification of build commands or require minor build option adjustments depending on how FFADO is built. * Aside from the manpage location, the introduction of DATADIR is not expected to change the path of any other installed files by default.
