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

Server Error in list archive?

by Peter P.

Hi list, trying to access my own message https://lists.linuxaudio.org/hyperkitty/list/linux-audio-user@lists.linuxau… just posted in this list in its archive index https://lists.linuxaudio.org/hyperkitty/list/linux-audio-user@lists.linuxau… repeatedly results in a "Server error" message. Is this a bug™? best, Peter

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

real time Grahic EQ

by Will Godfrey

Can anyone suggest such a program suitable for adjusting (while replaying) a pre-recorded vocal track? I used to use jamin, but that doesn't seem to run with current gtk versions. Must run with Jack. -- Will J Godfrey {apparently now an 'elderly'}

32-channel USB Dante interface found for Linux

by Brandon Hale

Hello all, I wanted to post a finding that I recently discovered. In the multichannel studios I work at, everything uses Dante. Because of this, I haven't really been able to output my laptop's audio directly, I have to find workarounds like going to analog to another computer, and so on. However, I recently found out a mixer that we have here, the Yamaha TF-Rack with Dante card <https://www.sweetwater.com/store/detail/TFRackDanteBun--yamaha-tf-rack-40-c…>, actually has a USB 2.0 interface built-in and with the Dante card, a Dante interface. It's expensive, but given that Dante interfaces can go upwards of $1000 USD and you get a mixer with analog ins and outs, it might be a pretty good deal. I just tested it out and it works, effectively giving a Linux computer 32 channels of Dante output. It gives 32 channels of input too, but since the Dante component uses the main 32 buses, I think to have input you have to sacrifice your Dante outputs. BUT, I didn't test that part as I was too eager to just get Dante output. That effectively can make this mixer a 32-channel USB Dante interface. I have been working here for 6 years and just discovered this. It's been here the whole time! I hope this information helps someone. Maybe mixers with Dante cards are the way for USB dante interfaces on Linux. (Lastly, I put the [LAU] in the subject line. Do I need to do this?) Thank you very much for your time, Brandon Hale
