This is the long overdone release for guitarix2 version 0.45.0 Guitarix is a modular, virtual amplifier for Linux. With Guitarix you can choose different preamp and amp models and /or could load *.nam files with the Neural Amp Modeler module, to simulate a specific hardware unit. Combine them with various effects and speaker cabinet emulations and/or load your own Impulse Response files to come up with your very own tones. ![guitarix](https://a.fsdn.com/con/app/proj/guitarix/screenshots/Guitarix_Dark.png/max/max/1) This release fix various bugs since the last release from May 2, 2022 It also introduce support for the outstanding [Neural Amp Moduler](https://github.com/sdatkinson/NeuralAmpModelerCore) project page: https://github.com/brummer10/guitarix release page: https://github.com/brummer10/guitarix/releases/tag/V0.45.0

KVR Music Cafe February Contest

by Will Godfrey

If anyone is interested, this month it's a free-for-all, but limited to 90 seconds max. There's about a week left, so enough time. There aren't any prizes, just the fun of trying to get top spot. So far I'm the only one using Linux. I could do with some company :/ -- Will J Godfrey {apparently now an 'elderly'} https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

by Stéphane Letz

Soundmit announces that it will host the International Faust Conference (IFC) 2024 in Turin, Italy, on November 21-22, 2024. The IFC is a biennial event that brings together the global community of developers and users of the FAUST audio programming language. The conference offers a unique opportunity to: Learn more about the FAUST language and its various applications Meet other professionals in the audio and music industry Attend talks, workshops, and panels on a variety of topics related to FAUST Contribute to the future development of the language The IFC 2024 will be held two days before the 14th edition of Soundmit, the international fair on synthesizers, electronic musical instruments, digital music and sound art, which will take place in Turin on November 23-24, 2024. The two events will be united for the first time, creating a unique opportunity for participants to fully immerse themselves in the world of digital audio. Companies that wish to support the conference can do so with a small sponsorship that offers a great return in terms of visibility. It is also possible to participate in the Soundmit as an exhibitor to present your products and services to an international audience of professionals. Dates: IFC24 - 21/22 Nov 2024 - Turin SOUNDMIT (14th edition) - 23/24 Nov 2024 - Turin https://www.soundmit.com/en https://ifc24.soundmit.com/en

Re: Teaching tool to visualize waveforms?

by Kevin Zembower

Fons, Dennis, davic and Lorenzo, Thanks very much for your responses to my question. I never thought of GNU Octave and gunplot for this task, mostly because of the extra steps it would require to listen to the resultant audio file. But, there are definite posibilities there. I've never heard of PureDAta or CSound, but will explore these programs. I also wasn't aware of Sonic Visualizer or Glava, but will explore these, too. Thanks, again, for your advice and guidance. I really appreciate your work to assist me. -Kevin On Tue, 2024-02-20 at 12:00 +0100, > > Message: 1 > Date: Mon, 19 Feb 2024 14:41:49 +0100 > From: Fons Adriaensen <fons(a)linuxaudio.org> > Subject: [LAU] Re: Teaching tool to visualize waveforms? > To: linux-audio-user(a)lists.linuxaudio.org > Message-ID: <ZdNanb9LkIQ2IduF(a)mail.linuxaudio.org> > Content-Type: text/plain; charset=us-ascii > > On Mon, Feb 19, 2024 at 09:21:37AM +0100, Lorenzo Sutton wrote: > > > On 18/02/2024 21:11, Kevin Zembower wrote: > > > > > However, we never saw a visual representation of the combined > > > waveforms.

Adjusting Pipewire Jack Buffer Size

by Brandon Hale

Hello all, Do any pipewire users here know of a way to adjust the buffer for pipewire for jack applications? Ideally, I'm looking for something that is a gui app or client command that can be adjusted on the fly, or before loading an application. I want to try to reduce latency for a performance and pipewire has been working great otherwise. My system is the latest universalblue fedora sericea and I am using a pro-audio interface.

MOTU 828 mkII USB

by soffioalcuore＠posteo.net

dear list members, I work in a school for some months now and a former colleague used to have a quite well equipped studio here. When I arrived he himself and most of the stuff he had here was gone. What's left is a MOTU 828 mkII USB. I would like to re-establish the possibilities of recording, podcasting etc at the school. but not on windows, but, of course, linux. now my question, does anybody of you know of a (secret) way of making that MOTU interface working in linux? I would love to use it w/o wiindows. any hint is much appreciated! cheers, christoph

Yoshimi V2.3.2 now out.

by Will Godfrey

The Echo effect can now have separate left and right channel delay times. Optimisations giving smaller code size and better efficiency. Small corrections and updates in the HTML User Guide. Various bugfixes. Full details are in /doc/Yoshimi_2.3.2_features.txt Yoshimi source code is available from either: https://sourceforge.net/projects/yoshimi Or: https://github.com/Yoshimi/yoshimi -- Will J Godfrey {apparently now an 'elderly'} https://willgodfrey.bandcamp.com/ http://yoshimi.github.io Say you have a poem and I have a tune.

Teaching tool to visualize waveforms?

by Kevin Zembower

Hello, all, I'm talking an Introduction to Audio Processing course at our local community college. In our third class, the instructor presented visually waveforms, using Apple ProTools, and we listened as they combined. The examples showed equal frequency waves with a phase delay, showing cancellation and amplification. We also listened to the beats of waves at frequencies like 440 and 445 or 450Hz. Finally we listened to pure sine wave, then the wave with 2nd, 3rd, 4th, 5th, etc. harmonics. However, we never saw a visual representation of the combined waveforms. As a former teacher, I thought it would enhance the lessons to also visualize the waveform. I think this could be done in Audacity, by mixing the waveforms to a final track, and viewing it. However, I think this would be somewhat clumsy. I also think that I could do this in GNU Radio, with mixing nodes and oscilloscope displays. Can anyone suggest a tool that would allow visualization of waveforms based on combined sine waves? My ideal setup would allow sliders to change the parameters, say, the phase delay, or frequency difference, in real time, and continuously display the combined waveform. Any thoughts or guidance is appreciated. Thanks for your advice. -Kevin

Guitarix goes Neural

by Hermann Meyer

Hi Today I've pushed support for the Neural Amp Modeler Core module to github. https://github.com/sdatkinson/NeuralAmpModelerCore <https://github.com/sdatkinson/NeuralAmpModelerCore> That means it is now possible to load nam profiles directly in guitarix. I've tried to implement it as seamless as possible, so I'm now interested in users feedback before I release and push it to the vst version. The module could be find now under the "Distortion" tab. I like to know if building from source works out of the box or if a extra call to |git submodule update --init --recursive| is needed. I like to know if model loading works seamless. I like to know if the resampling works seamless I like to know if someone is able to crash it. I like to know if the input/output controls cover the needed ranges. So, if you are brave and have some time to test it out, go and checkout the new sources and give it a try. https://github.com/brummer10/guitarix <https://github.com/brummer10/guitarix>
