[ANN] Vee One Suite 1.3.2 - A Mid-Spring'25 Release

by Rui Nuno Capela

Hello y'all, The 'Vee One Suite', the 'gang-of-four' 'old-school' software instruments, * synthv1 [1] as a polyphonic subtractive synthesizer; * samplv1 [2] a polyphonic sampler synthesizer; * drumkv1 [3] as yet another drum-kit sampler; * padthv1 [4] a polyphonic additive synthesizer. Are here released as a Mid-Spring'25 update... All delivered in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non/New Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Change-log: - Unassigned element/sample keys are now shown grayed out on the virtual piano keyboard. (drumkv1 [3]) - Added generic Ogg Vorbis container type filter (*.ogg) to sample file requester dialog. (samplv1 [2] and drumkv1 [3]). - Stepping up next development cycle (Qt >= 6.9) The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 1.3.2 (mid-spring'25) released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

NeuralRack v0.1.7 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 CLAP support - add option to handle presets in stand-alone version ![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.

Emulating guitar gear

by Goran Mekić

Hello, I spent some time researching Neural Amp Modeler (NAM) and Impulse Response (IR) technologies. As I had trouble finding how are those generated, I wrote a small series of blog posts with my findings. In short, I wrote how to create NAM and IR files to emulate existing gear. I am by no means expert in the field, on the contrary, this is the first time I'm doing this. I hope there are more experienced people in this field than me and if I made some mistake somewhere, they'll point it out. Enjoy! https://meka.rs/blog/2025/04/15/neural-amp-modeling/ https://meka.rs/blog/2025/05/11/impulse-response/ https://meka.rs/blog/2025/05/12/impulse-response-sweep/ Regards, meka PS. There are few comments on how to make FreeBSD perform better in audio production, but it's all jack, ardour, audacity and lv2, so the choice of operating system shouldn't be important.

LAC 2025

by Will Godfrey

I'm wondering who else is going to this. I'll be there of course. I see there's going to be a banquet on the 'crossover' day between jimlac and lac, which also looks quite inviting. My only concern is that I'm likely to be just about the only monolingual person there, which could be pretty isolating. -- Will J Godfrey

Reading and analysing spectral amplitudes as visually impaired person.

by Peter P.

Hi list, I am posting this to LAU in addition to the supercollider mailing list at https://scsynth.org/t/analysing-spectral-amplitudes-as-visually-impaired/11… A blind colleague has approached me with the need to read and analyse time-varying spectral amplitudes. I wonder what would be the best way to do this. I imagine one could do a python3 scipy stft and read the values from there, use some other text-based DSP software such as Supercollider or Csound. But let me first ask if anyone has any experience with this requirement and a possible soulution already. Thanks! P
