[LAU] Work on linuxaudio.org this weekend

by Jeremy Jongepier

Dear all, This weekend the linuxaudio.org VM's will have to be moved to a different cloud region which could lead to some downtime of services provided by linuxaudio.org (i.e. mail and web sites). We'll try to keep impact as low as possible and are aiming at a seamless migration. This migration is necessary because the cloud region linuxaudio.org now lives in is being phased out. We'll keep you posted about the progress. Best regards, Jeremy

[LAU] [ANN] Qtractor 0.9.11 - The Mauerfall'30 Release

by Rui Nuno Capela

Hallo! Not making history or a revolution but as peaceful as thirty years ago ;) Qtractor 0.9.11 (mauerfall'30) is out! And the change-log goes as follows: - Transport/Backward commands now honoring edit-tail, loop-end and punch-out points, when playback is not rolling. - A session name (sub-)directory is now suggested on every new session properties dialog. - Avoid adding any extraneous clip replica when Ctrl+dragging on either of its edges. - When using autotools and ./configure --with-qt=..., it is also necessary to adjust the PKG_CONFIG_PATH environment variable (after a merge request by plcl aka. Pedro López-Cabanillas, while on qmidinet [8], thanks). - Fixing a potential crash-effect in switching MIDI output buses on tracks that are set to show audio output monitoring meters, is on going still. 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] [Music] Silver (my entry into this year's Nexus challenge)

by Jeanette C.

Hey hey, Silver was my entry into this year's Nexus open source music challenge https://nexus-challenge.osamc.de/ I am happy to say that it came in second. :) This year's rules said that we were supposed to compose a song in the style of another song or a musicain. I chose Imogen Heap and hope that I maybe caught it tangentially. :) https://youtu.be/vJLG409oDek This song is licensed under the Creative Commons NonDerivative 4.0 license. Silver was recorded using Yoshimi, Csound and LinuxSampler as sound engines, Midish for tracking and Nama for recording the audio, mixing and "mastering". Feedback is welcome. To spare you one bother: I know that my vocals are substandard. :( Best wishes and enjoy all the same, 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 Our imagination Taking us to places We have never been before... <3 (Britney Spears)

[LAU] Jconvolver output format

by bricolodu

Hello, I have a setup that is running fine with : Raspberry Pi (I2S) / Squeezelite / Jack / Jconvolver / I2S DAC I have another DAC Chip, that I want to use, however it is not I2S, it is Right justified. I though that i just had to change the driver on the Pi from I2S to RJ but it doesn't work that way. It looks like the format should be changed at the output of jconvolver. Can someone confirm ? How could I change the audio format from jconvolver ? Best regards, Jean -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-user-f5.html

[LAU] Streaming low-latency bi-directional audio between Android 4.x and a Linux desktop

by Stuart Longland

Hi all, Firstly, apologies if this is not quite relevant to this list. I'll happily take it elsewhere if this is the case. I was wondering if someone knew of a tool that would enable me to connect my phone (running Android 4.1, I know this is old but it's what I have) over WiFi to my desktop (Ubuntu 18.04 LTS) or my laptop (Gentoo). I have a proof-of-concept going using JACK, icecast2 and darkice… I was able to get `qt-dab` to pipe audio to `darkice` and receive the stream from my phone using `HaveRadiosion`, however there's quite a bit of latency introduced, and it's one-way. Fine for music, but if I'm in a VoIP call with someone and have to step away from my desk at work I'm kinda stuck. Both JACK (netjack[12]) and PulseAudio are able to operate over a network. It seems all I really need is a compatible Android application that can link to the phone's headset and advertise that to the PulseAudio or JACK server. Before I go embark on a quest to scratch my own itch, is anyone aware of software that would allow such a link to take place? Regards, -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.

[LAU] Sonic Visualiser v4.0 released, along with Tony v2.1 and Sonic Lineup v1.0

by Chris Cannam

I'm delighted to announce new releases (made last Friday) of Sonic Visualiser and two related desktop applications from the Centre for Digital Music at Queen Mary, University of London: Version 4.0 of Sonic Visualiser, a free, cross-platform, open source application for viewing and analysing the contents of music audio files, is now available. The main change in this release, and the reason for the major-version bump to 4.0, is the addition of a "boxes" layer used to annotate and export time-frequency regions. (Refer to https://www.sonicvisualiser.org/doc/reference/4.0/en/#boxes for a description of the boxes layer.) See the home page at http://sonicvisualiser.org for more information and downloads. Version 2.1 of Tony, a free, cross-platform, open source application for high quality pitch and note transcription from solo vocal recordings, is now available. This is what you might call a "consolidation release" - it is almost unchanged from 2.0 in terms of features, but it is updated to fix some compatibility issues that have arisen since 2.0 came out and to prepare the codebase for a future feature release. See the home page at https://www.sonicvisualiser.org/tony/ for more information and downloads. Version 1.0 of Sonic Lineup, a free, cross-platform, open source application for comparative simultaneous visualisation of multiple audio files containing versions of the same source material, is now available. See the home page at https://www.sonicvisualiser.org/sonic-lineup/ for more information and downloads. Chris

[LAU] [ANN] Vee One Suite 0.9.11 - A Halloween'19 Release

by Rui Nuno Capela

Horror! The 'Vee One Suite' of so called 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here and now released for the global Halloween evening, and all making up to this mythical version 0.9.11 ;) As always, all provided in dual form: - a pure stand-alone JACK client with JACK-session [5], NSM (Non Session management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Changes for this creepy release are quite revolutionary;) - When using autotools and ./configure --with-qt=..., it is also necessary to adjust the PKG_CONFIG_PATH environment variable (after a merge request by plcl aka. Pedro López-Cabanillas, while on qmidinet, thanks). - Upstream packaging is now split to JACK standalone and LV2 plugin only: the former shared common core and UI package is now duplicated but statically linked though.

[LAU] Xmonk.lv2, aLV2 toy

by Hermann Meyer

I remember last time on a VST which I found nice to play around with, don't remember the name, but it was a monk which sing when you push and move the mouse. While I work on the code of my new X11/cairo toolkit, I give this a shoot. I'm using the SFFormantModelBP from the faust physmodels.lib, and wrap a UI around so that it comes near to what I remember and have a lot of fun while moving the mouse around on it. Then I adding midi support (modwheel for the vowel), so that it may become a tad more the fun. HOOOHEEEHAAA, here you go: https://github.com/brummer10/Xmonk.lv2

[LAU] It's the final (Sonoj) countdown! - live feed with chat - donations

by Sonoj Convention

The end is near! Fortunately only the end of our preparations. Only four days left until this year's Sonoj Convention. For the spontaneous among you there is still an opportunity to sign up and visit. Just enter your name on https://sonoj.org/register.html . Considering the many mails you've received so far, it can be assumed that you're currently in Antarctica and therefore can't actually participate. Therefore now for the last time (this year): Please help us finance our non-profit event by donating an amount of your choice. We accept bank transfers and PayPal: https://sonoj.org/donate.html And finally I would be happy to see you during the two days in our video stream. There will be a chat this year (it already exists), so you can ask questions and comment. The stream is on the Sonoj page, or here: https://streaming.media.ccc.de/sonoj2019 Best regards, Nils Sonoj Convention
