Hi, What is the recommended way to build zynaddsubfx these days? There are two repos it seems: https://github.com/zynaddsubfx/zynaddsubfx https://github.com/zynaddsubfx/zyn-fusion-build Regards, \r

[LAU] Physical distance performance with Linux?

by Mac

In our current world situation I see a lot of videos, and in some cases live, performances by multiple musicians/vocalists in physically different locations. Some are obviously in a MacGyver setup in the closet, others are in rather tricked out home studios (like the one I just watched of the Doobie Brothers, where they all were in their own studio). Some are obvious compilations, video effects, etc. added. But, when they are live how do they deal with delays and monitoring for the local performance (in the Doobie's one, there was some post processing, but, the duets seemed really tight, both instruments and vocals.) My question is, have any Linux folks had any experience setting this, with Linux tools obviously..., and how did you deal with delays and monitoring when live or (I assume when processed video is involved) monitoring and delay for multi-tracking from around the world? Regards, Mac

[LAU] How to prevent applications from changing my mic level?

by S.

Hi there, recently I've been running into major problems with Electron apps for the Linux desktop (Microsoft Teams and Riot.im) modifying my mic input levels. Also Chrome / Chromium do the same thing during WebRTC calls, they raise my mic level to 100%, thus completely saturating the audio and making it unusable. I drop it back down manually, but within a few seconds it creeps back up to 100% again. In Windows there's an option to not allow programs to control a specific device. Is there any way to do this with ALSA and/or PulseAudio? Thanks a lot. -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-user-f5.html

[LAU] [ANN] Qtractor 0.9.14 - A Mid-Spring'20 Release

by Rui Nuno Capela

Congratulations! No matter what others say, you are here and that's awesome! You are also here kindly reminded to update to the very latest and greatest. There's no better time for just that than pretty much now! And now this: Qtractor 0.9.14 (mid-spring'20) is out! Notwithstanding some nasty crash-bugs being squashed--hopefully for good--changes for this mid-season release are as follows: - Export file type, format and quality are now specific options on the Track/Export Tracks.../Audio, MIDI dialogs. - LV2 plug-in UI GTK2 and X11 in Qt5 host native support in addition and alternative to libsuil. - Generic plug-in/Properties... dialog now showing each parameter/property automation status on a /skeuomorphic/ aka. /fake/ and tiny LED ;) - LV2 Plug-in Patch parameter/properties automation and MIDI Controller assignment/learn are now a possibility. - LV2 Atom/Port-event host notification support has been implemented (unofficial). - Fix clean-up of any recording leftovers. - JACK Transport latency is now taken into account for recording latency compensation. - Attempt to force correct audio clip offsets due on recording latency compensation are not quantized to MIDI metronomic time-scale anymore. - LV2 Plug-in MIDNAM support introduced. - Use Shift or Ctrl keyboard modifiers with the mouse- wheel to change any Direct Access plug-in parameters (issue #257). 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.

[LAU] [acma-l] "Mosca v0.3" SuperCollider quark released

by Iain Mott

Dear list, I'd like to announce the release of a new and greatly improved version of the SuperCollider "Mosca" quark for three-dimensional sound spatialisation. The notes for the release are as follows: "Revised SuperCollider quark for three-dimensional sound spatialisation, with recent developments featuring the work of Thibaud Keller from SCRIME, University of Bordeaux. Mosca includes multiple spatialisation libraries assignable on a per-source basis, banks of RIRs for both 'close' and 'distant' convolution reverberation (again on a per-source basis), support for higher-order ambisonic signals and sound files, improved GUI, OSC interface for the intermedia sequencer OSSIA/score and many other improvements and optimisations." Once the quark is installed, documentation found in the help file for the Mosca. On the help page, see the link for the "Guide to Mosca" for full documentation. The source code is located here: https://github.com/escuta/mosca Also available is the paper "Three-dimensional sound design with Mosca" that Thibaud and I presented at a conference last year: https://www.researchgate.net/publication/336983923 Please let us know if you use Mosca in any projects! All the best, Iain Mott ________ Iain Mott mott(a)escuta.org iainmott(a)unb.br https://escuta.org http://cen.unb.br

Not what I expected, so I am curious why there is not more added latency from the routing out of your ISP and into the other ISP. Perhaps the latency on the modems is high enough that the customer end equipment dominates over the routing delays. > It is worthwile noting that we are limited by the speed of light. 300km/ms speed of light, the lowest ping time I have ever seen from my computer to a machine outside my house is about 20ms. I know not all of those machines were 6000km away, so I think speed of light is pretty low on the list of factors influencing delay. Yes for large distances, but should not have been a factor in your connection inside the same city through the same ISP. > I read a paper a while ago which stated that most delay occurs in the > access network, the last mile, due to shared media and signal > multiplexing. Also both DSL and cable modem involve lots of pretty sophisticated DSP operations, that all takes time. I have not seen any information on time delay between ethernet packet in and cable or DSL packet out, or the reverse. That may be a significant portion of the delay. And for anyone not familiar with the term "bufferbloat" or "buffer bloat" you should verify that you are using appropriate active queue management at your home router. There have been many papers, blogs, presentations, etc. on how poorly most equipment manages network queues at the points where network bandwidth changes (such as from your home 1Gb connection to the usually much slower upstream connection). If the queues are too deep then many packets can be buffered in the network equipment waiting for transmission, especially if you have multiple applications active and sharing network bandwidth simultaneously. -- Chris Caudle

[LAU] [Music] Blood Lust (stomping electro)

by Jeanette C.

Hey hey, this latest one was inspired, in equal measures, by Hyper's Spoiler - soundtrack to a game or film: Cyberpunk - and French house duo Justice. This is based on some fun tutorials/pastiches: https://youtu.be/136ft7B1iOw This song uses Csound - sampled into LinuxSampler - quite extensively, it also features Yoshimi and some hardware. In terms of plugins here's a shoutout to the decimator by Steve Harris. Never had much use for it before, except for honest destruction. :) Feedback is welcome. 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 I'm reaching out to you To find that you're not there <3 (Britney Spears)

[LAU] Louigi Verona interview: the challenges and the rewards of writing electronic music

by Louigi Verona

Hey everyone! I am mostly known as an ambient producer, but also as the defender of electronic musics without melodies (bwahaha), as well as the popularizer of generative methods of music making. Well, here you go, an interview were I combine all of my best qualities as the ambassador of electronic music with evocative storytelling. Enjoy! https://www.youtube.com/watch?v=_u3FDUI03Ck Louigi Verona https://louigiverona.com/
