[LAU] [Music]: Cooking Meth (an experiment)

by Jeanette C.

Hey hey, whilst on holiday I did not only play the piano and embarrassingly sweet ways. My friend has a very lovely studio with a powerful Linux machine and some outboard equipment. So as an experiment, we did record a very short electronic piece. For now, I'd like to show withgout further comments about the experimental nature, maybe it is obvious after all: http://juliencoder.de/nama/cooking_meth.ogg http://juliencoder.de/nama/cooking_meth.mp3 Feedback is welcome, especially if something strikes you as particularly odd about it. :) Or if you just happen to like to really hate it. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s I can't believe it's what I see That the girl in the mirror The girl in the mirror Is me <3 (Britney Spears)

[LAU] How to automatically start zita-j2a/a2j with jack?

by Steven Kruyswijk

Hi all, For a sound playback system I'm putting together, based on a Raspberry Pi 3, I'm looking to have 4 channels of input and output, and to have the system to run automatically at startup. For this, I'm wondering how to (best) execute zita-a2j and zita-j2a; I've tried two methods that don't work: 1. ask Qjackctl to execute the following script after startup: sleep 5 zita-j2a -d hw:CODEC_1 2. execute this script: qjackctl (with auto-start) sleep 10 zita-j2a -d hw:CODEC_1 Executing the zita-j2a manually after Qjackctl has finished starting the jack server does work. Any pointers greatly appreciated! Cheers, Steven -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-user-f5.html

[LAU] New music: Chroming the dice

by Jeanette C.

Hey hey, this is an ambient little piece, originally written to demonstrate Cubicon, a 3d wavetable oscillator written as a Csound UDO: http://juliencoder.de/sound/m_cubicon-0.5.zip There is a youtube video with a self-made animation: youtu.be/_AbASO7n4Ho Sorry, about the quick changes in the walls, that wasn't intended. There were two difficulties involved: 1. each frame took ages to render and 2. I am as good as blind and thus anything but subtle with graphics. :) If you'd prefer better audio, this piece is a 3D binaural work, so best to listen to on headphones anyway: http://juliencoder.de/nama/chroming_the_dice.flac http://juliencoder.de/nama/chroming_the_dice.mp3 http://juliencoder.de/nama/chroming_the_dice.ogg If you are really curious, there is the full Csound source code, ready to render yourself: http://juliencoder.de/nama/chroming_the_dice.zip And for the incurably nosy, I could hand out the POV-Ray sources for the animation. Other than that: I hope you can enjoy it and might let me know if you do so. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s Don't, don't let me be the last to know Don't hold back, just let it go <3 (Britney Spears)

[LAU] Using JACK without an audio card

by Erik Schoster

Hello! I'm setting up a remote server now to run generative audio ideally routed via JACK to liquidsoap and out to a web radio stream. The server is a physical machine colocated in a datacenter but I'm not sure if I will be able to install an audio card into it -- it would be easiest if I didn't have to. Does anyone know if there a way to run jack for routing internal audio without an actual audio card? I'm also interested in using jacktrip on the server. Thank you! Best, Erik

[LAU] External Class Compliant Sound Cards

by Kamil Adiloglu

Dear list, I am compiling a list of suitable sound cards for a mobile real-time experimental setup. There are some criteria that such a sound card should fulfil: - External sound card: We have a mini PC with an on-board sound chip. We want to use an external sound card with a decent sound quality. Our mini PC has USB-2, USB-3, USB-C (Thunderbolt 3) connections. - Class compliance: We have a real-time signal processing platform, the Master Hearing Aid, which runs on Linux (Actually it also supports Windows and Mac, but we prefer Linux). Therefore we need a sound card, which Linux can operate. Manufacturers usually do not officially support Linux, but there are some, which run on Linux, because they are class compliant and do not require a dedicated driver. - At least 4 (preferably 6) analog (identical) inputs and at least 2 analog (identical) outputs - Lower sampling rates: As we will do real-time signal processing, we prefer lower sampling rates for the sake of computational complexity. Therefore, ideally we would like to have a sound card, which supports even 16kHz, but 32kHz also OK. I know that these criteria are not easy to fulfil. So far, I couldn't find any sound card, which fulfils all the requirements. In the worst case, we can sacrifice the last requirement and downsample our sound input before processing, but it is a good-to-have one. We would appreciate any suggestion. Thank you in advance. Best Regards, Kamil Adiloglu

The changes for this Last of Spring'19 release are: - Improved slew-rate to DCF Formant coefficient updates. - Refactored the LFO Sync for correctness. - Dropped LFO Sync parameter as being irrelevant across element voicings. (drumkv1 [3] only) - Fixed all LFO Panning and Volume modulation, now being correctly isolated on a per voice basis. - Fixed DC offset on all main DCO wavetable oscillators. (synthv1 [1] only) - Fixed initial DCO and LFO wave shapes on LV2 plug-in UI. - Minor update to Debian packaging control file. The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later. **synthv1 - an old-school polyphonic synthesizer [1] ** synthv1 0.9.8 (spring'19) is released! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.
