Ambisonics: Which order fits my project?

by Michael Jarosch

Hi! Speaking about Ambisonics, I have one question regarding the different orders you might want to use, which I couldn't found to be answered in the (not too much) media I read and watched about this topic: Which border do I have to reach in my project that I should consider switching to higher (second, third or more) order ambisonics? Is it the number of output channels? Or is it: Always use the highest order you can afford? According to this video <https://www.youtube.com/watch?v=f4oE3i2tjyA>(, which I haven't watched the whole length,) at 23:14 ff it's about frequency response and compensation - and there it seems to be better using lower order. It would be interesting making a direct comparison between first and third order to hear if it's worthwhile. But without the equipment… So, this question goes to the pros (hoping not to start a flamewar…) There is another video <https://www.youtube.com/watch?v=kFuKaKbfxls> I found. Without ever being able to hear higher order ambisonics I wonder if such things as fifth order is more or less something like "look, what I can do" comparing the time and effort with the actual improvement in audio quality… Sorry, if I step on someone's feet… Greets!

Edirol FA101 on Ubuntu

by di.heumo＠gmail.com

Hi there, I'm new to the list. Composer/musician using Supercollider, I just moved from MacOS to Ubuntu 18.04. I was under the impression that the Edirol FA101 firewire audio interface should be working on Ubuntu, but I find it hard to figure out where to begin. The device is connected with an adapter to a Thunderbolt port on my Dell laptop. cat /proc/asound/cards does not show the device unfortunately. When I do lspci -tv in terminal, the Thunderbolt port seems to be recognized: +-1b.0-[02-3a]----00.0-[03-3a]--+-00.0-[04]----00.0 Intel Corporation JHL6340 Thunderbolt 3 NHI (C step) [Alpine Ridge 2C 2016] | +-01.0-[05-39]-- | \-02.0-[3a]----00.0 Intel Corporation Device 15db Can anyone point me in some direction for a solution to this? Thanks! Robert ★ Robert van Heumen software developer, composer, sound designer, improvisor west28.nl[1] -------- [1] west28.nl

- jackd audioadapter vs alsa_in & _out vs zita_a2j & _j2a

by Athanasios Silis

Hi all I am looking for some info on which client should one use in order to enable a 2nd sound card on the jack server or any of the jack client computers. I can see in zita's website that zita clients seems to be an improved versionnnnnn of alsa_in & _out clients, but I would like for other people to comment on that as well. Where I am completely in the dark is where audioadapter stands in all this ... Best regards, Athanasios

mcpdisp-0.1.2 release

by Len Ovens

MCPDISP is a utility to add a display on to a Mackie Control based control surface that does not have it's own display such as the bcf2000. This is important if banking is being used (the project has more than 8 tracks) and also provides things like timecode or bar/beat readouts. At present this is a jackd only utility though it should be possible to bridge to ALSA using a2jmidid. Perhaps a later version will move to ALSA MIDI instead. The latest version can be found at: https://github.com/ovenwerks/mcpdisp/releases/tag/mcpdisp-0.1.2 Some Packaging scripts were optimizing the buffer to the stack. This release fixes that. Licenced as GPL-2+. -- Len Ovens www.ovenwerks.net

[music] Early Music live stream concert from 5 different locations

by Giso Grimm

Dear LAUs, on July 7th, 2020, 6pm CEST our viola da gamba ensemble ORLANDOviols will play a concert, connected and streamed using FLOSS: The Gentle True Spirit a happy concert in these distracted Tymes http://www.orlandoviols.com/ free admission During these distracted times without concerts we developed an audio interface which allows us to play music together despite our spatial separation. We have been playing together in our virtual rehearsal room since mid April, exploring rarely played repertoire. This allowed us to develop a new concert programme revolving around the six-part Fantasies of the progressive young composer William Lawes, who unfortunately died much too young (1602-1645). This programme will be presented as a streaming concert: performed at five different locations simultaneously, connected through the internet. Your concert experience is not only about hearing - you can watch us playing in an interactive virtual space, arranged around you. Join us and explore! Viola da Gamba: Frauke Hess, Júlia Vető, Hille Perl, Marthe Perl, Giso Grimm, Claas Harders Streaming assistant: David Grimm Looking forward to 'meet'(*) you there! Best, Giso (*) Chat messages will be answered at the end of the concert

ALSA MIDI buffer size

by Brent Busby

I've been working on a problem with a Perl program sending and receiving large sysex dumps via the ALSA::MIDI module. It looks like there is a 4kB buffer in ALSA rawmidi that can be overrun if things go in or out too quickly. Keeping it from filling too fast outgoing is easy. But since there is no way for MIDI to tell the remote sender to slow down, preventing buffer overruns from incoming data is turning into a problem. Is there a way I can either tune the size of the buffer from Perl, perhaps with some kind of library call to ALSA's raw MIDI API, or somehow make the access blocking so that it won't try to take more data than it can handle? I've been looking at the C source for the amidi command, but I'm trying to deal with this in Perl if possible. It seems to depend a lot on how fast the device wants to send, but some devices break the sysex transfer into chunks and try to slow down, and other don't bother and just expect you to keep up.

[ANN] Qtractor 0.9.15 - An Early-Summer'20 Release

by Rui Nuno Capela

Hi y'all! Let's go straight to the real good news ;)... Qtractor 0.9.15 (early-summer'20) is released! Change-log: - Fixed MIDI tracks export that were missing the end-of-export tail parameter and bailing out always with default SMF format anyway. - Fixed VST3 component/controller inter-connection. - LV2 Atom/Port-event host notification support has been retouched, but still unofficial though. - Fixed VST3 audio-processor initialization/activation when a plugin has no inputs or outputs present. - Let main window pseudo-asynchronous stabilization re. menus, tools and status bars, just faster and immediate. - Fixed MIDI track monitor re-instantiation and reset. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
