Ratatouille is a Neural Model loader and mixer for Linux/Windows. This release implement easier File switching. It's now possible to switch the selected files via mouse wheel, via mouse button click and via keyboard up/down keys. Right mouse button click will pop up the file-list and allow to select a file directly. Also, it implement lighter CPU usage for convolution (IR-File), on non power-of-two buffer sizes, by using the multi threaded FFTConvolver engine. Beside that the GUI was a bit overworked. 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 <https://cloud.aida-x.cc/all>/.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. 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.

Ratatouille.lv2 v0.5 released

by Hermann Meyer

Ratatouille is a Neural Model loader and mixer for Linux/Windows. This release fix handling frame buffer-sizes of arbitrary size, aka. not power of two, for the impulse response engine. 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.

SpectMorph 1.0.0-beta2

by Stefan Westerfeld

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

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

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. For additional info on L2Ork visit https://l2ork.music.vt.edu This project is sponsored by the Department of the Navy, Office of Naval Research under ONR award number N00014-22-1-2164.
