[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!

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

[LAU] Sacred Mountains

by Louigi Verona

Hey everyone! Allow me to present this dark soundscape that sends you on a journey to a sacred place, which is both alien and comforting. Somewhere which is the very definition of far away, and yet somehow speaks to us, as if it's our long forgotten home...

[LAU] How to combine microphone audio and music from application to pipe to video conference

by Samir Parikh

Hello, I am trying to combine the audio from my microphone (either built in microphone from my laptop or bluetooth headset) with music playing from Rhythmbox Music Player running on Ubuntu 16.04 and pipe that as the audio input to video conference services such as Jitsi. I don't know much about Linux audio internals and wasn't sure how to do this. Can I do this completely via the operating system using Pulse Audio? Do I need to do something with Jack? Or do I need specialized software such as OBS, Ardour or Reaper? Any help or suggestions on pointing me in the right direction or how to get started would be greatly appreciated. I'm hoping that I can do this completely through software without external hardware such as a mixer or something. Thanks in advance. Samir

[LAU] [music] a baroque(ish) piano partita

by Jeanette C.

Hey hey, another item off the todo list: https://youtu.be/RwlJyio5tGc I call it partita, though it doesn't really fulfil the requirements, only having five movements for a start and then you could discuss proper classification for each of them. But - except for the prelude - they are all counterpunctual. It was played live on a commerical gigasample piano in LinuxSampler, recorded into Nama, processed in Csound with and HRTF based binaural room/reverb. I hope you enjoy it, feedback is welcome.
