Ratatouille is a Neural Model loader and mixer for Linux/Windows. New in this release: * allow to build as clap plugin * allow to build as vst2 plugin 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. Ratatouille allow to compensate phasing issues between the loaded Models. The "Delay" control could add a small delay 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.

NeuralRack v0.1.8 released

by Hermann Meyer

NeuralRack is a Neural Model and Impulse Response File loader for Linux/Windows. It supports [*.nam files](https://www.tone3000.com/search?tags=103) and, or [*.json or .aidax files](https://www.tone3000.com/search?tags=23562) by using the [NeuralAudio](https://github.com/mikeoliphant/NeuralAudio) engine. For Impulse Response File Convolution it use [FFTConvolver](https://github.com/HiFi-LoFi/FFTConvolver) Resampling is done by [Libzita-resampler](https://kokkinizita.linuxaudio.org/linuxaudio/zita-resam… New in this release: - add vst2 support - fix issue with Clap GUI in Bitwig - fix issue with hyper accurate models - fix IR-file not applied to right channel ![NeuralRack](https://github.com/brummer10/NeuralRack/raw/main/NeuralRack.png?raw=true) Neuralrack allow to load up to two model files and run them serial. The input/output could be controlled separate for each model. For tone sharping a 6 band EQ could be enabled. Additional it allow to load up a separate Impulse Response file for each output channel (stereo). Neuralrack provide a buffered Mode which introduce a one frame latency when enabled. It could move one Neural Model, or the complete processing into a background thread. That will reduce the CPU load when needed. The resulting latency will be reported to the host so that it could be compensated.

Qtractor 1.5.5 - A Mid-Spring'25 Release

by Rui Nuno Capela

Hi everyone, Qtractor 1.5.5 (mid-spring'25) is out! Change-log: - Fixed negative time values displayed in tool-tips, when dragging the rubber-band (lasso) to the left, over the absolute beginning of the timeline. - A warning is now issued when an audio self connection is made (eg. connecting an output bus (or insert send) directly into an input bus (or insert return). - Files item selection mode switching corrected. - Mitigate or postpone a 'too many open files' condition as much as possible. - Let muted clips show the "[Mute]" tag as the name label prefix, so that it's visible even on small clips. - Stepping up next development cycle (Qt >= 6.9) 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.

audiowmark-0.6.5 - Audio Watermarking

by Stefan Westerfeld

Hi! audiowmark-0.6.5 is now available at https://uplex.de/audiowmark Overview of Changes in audiowmark-0.6.5: * improve robustness for low quality material - robust sync score peak selection using local mean - use lower sync threshold (introduce --sync-threshold option) - always decode n best matches (introduce --n-best option) - distance based AB pattern merging - distance based ALL pattern merging - change output order: print most relevant matches first - deprecate short payload * fix speed detection result output for default key * ship more m4 macros to fix automake on some target systems audiowmark is an open source solution (GPL3 or later) for watermarking audio files. It has many features, it is robust, fast, secure and of course we believe that the watermark is not audible for most users. The project page provides the documentation and source code as well as some audio demos, so you can check whether you hear a difference between original and watermarked files. Cu...
