Hi all Does anyone have experience with the uTrack24? Specifically 1) thoughts on audio quality 2) works with Linux? 3) do you need a computer to have use it as 24 in 2 out with control over mix? https://cymaticaudio.com/utrack24-productpage/ I was thinking pairing with a few of these (or similar) for 24 channels of modular into the computer https://nw2s.net/products/nw2s-io Atte

[LAU] Kudos tothe LiSP Gang

by Jostein Chr. Andersen

Hi! I want to give some thumbs up to the LiSP (Linux Show Player) gang! The weird thing is that I don't know how overdue this is. I asked them on this list some years ago if the program supported multi-channel or multi-tracks, the answer that time was no, so I gave it up. But today, I checked again. I downloaded the AppImage, made a multichannel FLAC file and voila: -It worked! Now, the artist can have his/her own backing track (with count ins, pilot tones, etc) and the audience another one. Great! So.. Thank you LiSP! :-) It's other people to thank as well, giants such as Fons Adriansen, Paul Davis, Rui Nuno Capela, Hermann Meyer, Dave Phillips, and countless others (already starting to regret the name dropping). I think I'm gonna sit down and send good thoughts to all of you (no money - I'm broke) and I'm so grateful for what you have done and are doing. Big thanks to you too, you have made my life as a Pragmatic Open Source Fanatic easier and easier for every year! <3 Jostein

[LAU] Matthias Kronlachner ambiX & mcfx plugins

by baptiste chatel

Hi list ! This is my first message here. I am currently trying to set up a live ambisonics mixing desk equivalent with Pure Data and [vstplugin~] object. Most of the work is done with the IEM suite and some SPARTA plugins, but i'd like to evaluate all the plugins i can. I tried to compile Matthias Kronlachner ambiX and mcfx plugins but failed miserably, mostly due to GCC 9.1 incompatibilities. Does anybody have both ambiX and/or mcfx compiled for Ubuntu 20.04 x86_64 ? I'd prefer VST version for the sake of consistency but LV2 would be ok too, i guess. Thanks ! Baptiste

[LAU] [Music] binaural 3D: The Cylinders and the Spheres

by Jeanette C.

Hey hey, this is another Csound composition, a virtual scene: https://youtu.be/LGaynaBbTVw Youshould listen on headphones and, if possible, keep rather still. :) The image that I tried to build is of a large hall, where the listener hangs in the air at the centre of a sphere constructed of metal balls connected by wires. At the front wall there stands a group of wooden pipes or huge clarinets that, after a while, begin a procession around the listener. Occasionally they fire a kind of table tennis ball like fireworks. Along the side walls there are metal bars, applauding the pipes. On the other hand, you might just hear it as an abstract composition or whatever suites you. For the eternally curious there is the full Csound source code available, everything is synthesized, no samples have been harmed in this rendition: http://juliencoder.de/nama/cylinders_and_spheres.zip Enjoy and best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * SoundCloud: https://soundcloud.com/jeanette_c * Twitter: https://twitter.com/jeanette_c_s * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Can't you see I'm a fool in so many ways <3 (Britney Spears)

[LAU] Getting Rhythmbox to Appear in qjackctl

by Samir Parikh

Hi Everyone, I'm back! How do I get Rhythmbox (GNOME application similar to iTunes) to appear in qjackctl? To recap: I'm trying to take the output of music playing from Rhythmbox and combine that with my microphone (either onboard laptop or bluetooth headset) to pipe both into the Jitsi Meet videoconference service[1]. Thanks again to everyone who has been helping me thus far. Based on the feedback I received, I'm going to try to solve my issue using JACK. Over the past few days, I have been doing more research, reading wiki pages and watching YouTube videos to become more familiar with JACK and the various tools. Thus far, I have: - installed qjackctl and its dependencies on Ubuntu 16.04 - updated /etc/security/limits.conf with: @audio - rtprio 95 @audio - memlock unlimited per these instructions[2] - added my userid to the audio group - installed pulseaudio-module-jack - installed gstreamer1.0-plugins.bad - I have NOT installed the low latency kernel I can now start the JACK server without any XRUNS after changing my Output and Input devices to hw:PCH but I can't get Rhythmbox to appear under "Readable Clients/Output Port" in the Connections window in qjackctl. I'm struggling to figure out how to set these GStreamer values[3] assuming that this is even the solution to my problem. Any pointers in the right direction would be appreciated.

[LAU] VST version of the swh plugins?

by Jeanette C.

Hey hey, does anyone know if there is a VST version of the SWH plugin suite, originally by Steve Harris?

[LAU] [Music] early 90s techno inspired track

by Jeanette C.

Hey hey, I just released "Feet of clay": https://youtu.be/nMboaOCJNtA It is inspired by early 90s techno/electro, though a little more melodic and it consists of two eight bar patterns, so too complicated. :) Instruments were entirely hardware and entirely analogue. On the mixing side there is a lot of spice from CAPS, compression, TAP Tube Warmth and the Invada studio compressor in the lead. Enjoy! Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * SoundCloud: https://soundcloud.com/jeanette_c * Twitter: https://twitter.com/jeanette_c_s * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c But now I'm stronger than yesterday <3 (Britney Spears)

Only to the extent of estimating whether that is the actual range of latency to expect from your house to the upstream router, or whether there is additional latency added on to that as a minimum. > But I can confirm ~35ms on the first hop with my cable access... Is that 35ms one way, or round trip? Is that the value reported from traceroute? I'm looking at that now at my house, but I'm not familiar with how to interpret the numbers, I will need to study the man page a bit. But if the interpretation is as obvious as it seems then it seems like the system in our neighborhood has not bad latency after the latest upgrades. > Where did you find that info? Google search found a document at CableLabs titled "DOCSIS Technologies for Mobile Backhaul" discussing considerations for using cable based network as the connection for small cell phone stations. Similar considerations for conversations as for music, if the latency is too long you begin to speak over each other, conversation timing is awkward, etc. so seemed like a relevant document. https://www.cablelabs.com/docsis-mobile-backhaul-white-paper https://cdn2.hubspot.net/hubfs/1697621/DOCSIS-Technologies-For-Mobile-BackH… best regards, Chris Caudle
