The Sonoj Convention is a great opportunity to meet like-minded people, maybe even to have engaging discussions! Every man and woman is welcome, no matter your musical or technological background. An event like the Sonoj Convention does not exist yet. While commercial and closed-source products have plenty of platforms the open source, and sometimes hobbyist, scene does not. The official website https://www.sonoj.org offers a simple way to register as a visitor for free as well as more information, such as an overview of our talks, demonstrations and workshop (e.g. "Boring Music and How to Make it Interesting" or "Creating a Radio Drama with Ardour (for Beginners)"). If you can't attend personally but want to support the convention you can donate to our small fundraising-campaign ("Donation" on the website) and help covering our expenses.

USB audio interface

by Thijs van severen

hi all I know this question pops up every couple of months (repeat,repeat,repeat) but since i cant find any up to date info, i'll ask it anyway :-) I'm looking for a new audio interface with these minimum specs : - USB - plug-and-play (as in 'works OOTB with no extra drivers needed or compiling anything') - 8 in (minimum 2 mic ins) - 8 out - no internal DSP or hardware mixer (unless it is possible to config using a native linux app) - i will be using this live on stage so it needs to be solid and low latency - 500eur max I have checked out all the usual 'hardware compatibility' matrix wikis and related websites but 90% of that info is outdated, hence this mail All suggestions are welcome ! Grtz Thijs -- follow me on my Audio & Linux blog <http://audio-and-linux.blogspot.com/> !

Job opportunity Linux audio/C++ in Oldenburg, Germany

by Giso Grimm

Dear Linux Audio community, please find below a link to a job opportunity in Oldenburg, Germany, in the field of open source software development: http://www.hoertech.de/en/h%C3%B6rtech/career.html The work is mainly development in C++ for the Master Hearing Aid, which we presented back in 2009 at the LAC in Parma (http://lac.linuxaudio.org/2009/cdm/Friday/07_Grimm/index.html), and which will become open source within the next months. The job position is at a small company in a team of developers, with close collaboration with the university of Oldenburg. For details, please see the link above.

But I wonder about one small thing related to C++. Couldn't these max/mean/etc. methods in the Statististics class be written shorter like this?: auto max() const { return Max(Accumulator); } auto mean() const { return Mean(Accumulator); } auto min() const { return Min(Accumulator); } auto sampleCount() const { return Count(Accumulator); } auto variance() const { return Variance(Accumulator); } Sorry if it's a stupid question, but I haven't used "using" in C++ yet. :-) Also thanks for demonstrating these things from boost.

[BrlCV] My attempt of linking Linux to Eurorack

by Mario Lang

Hi. As I was recently sucked into the Eurorack world, I have begun to work on a small C++ project to create tools for working with control voltages. My ultimate plan is to write a small software CV sequencer. But until then, I am going for low hanging fruits, esp. so that I can warm up to writing JACK code. One of these is cv2midiclock. It takes a CV signal (actually works with Line-In as well, but my ultimate plan is to use an Expert Sleepers ES-8 to get DC-coupled AD/DAC) from an audio port and outputs a synced MIDI Clock on a MIDI port. Very simple, very basic, but might be useful, actually. https://github.com/mlang/brlcv Disclaimer: This repository will never implement any sort of GUI. In fact, it is likely that the only user interface the control voltage sequencer will ever have is going to be based on a Braille display. You are welcome to fork the code to port it (once it works) to other user interfaces. Patches to implement visual UIs will be rejected, as was the case with my patches to improve GTK Accessibility. However, if you are fine with CLIs or OSC and have an interest in CV tools on Linux, you are very welcome to join forces. P.S.: This repo contains my version of a C++ wrapper for JACK clients. While it is definitely not complete, it can be used to implement simple JACK clients in very few lines of code. If you are into modern C++ (C++14 and beyond), take a look. If you like/dislike it, send feedback please. Below is (totally useless) example client: #include <jack.hpp> #include <boost/accumulators/accumulators.hpp> #include <boost/accumulators/statistics.hpp> template<typename... Features> using AudioAccumulatorSet = boost::accumulators::accumulator_set< float, boost::accumulators::features<Features...> >; using Count = boost::accumulators::tag::count; using Max = boost::accumulators::tag::max; using Min = boost::accumulators::tag::min; using Mean = boost::accumulators::tag::mean; using Variance = boost::accumulators::tag::variance; class Statistics final : public JACK::Client { JACK::AudioIn In; AudioAccumulatorSet<Count, Max, Mean, Min, Variance> Accumulator; public: Statistics() : JACK::Client("Statistics"), In(createAudioIn("In")) {} int process(std::uint32_t FrameCount) override { for (auto &Value: In.buffer(FrameCount)) Accumulator(Value); return 0; } auto max() const { return boost::accumulators::max(Accumulator); } auto mean() const { return boost::accumulators::mean(Accumulator); } auto min() const { return boost::accumulators::min(Accumulator); } auto sampleCount() const { return boost::accumulators::count(Accumulator); } auto variance() const { return boost::accumulators::variance(Accumulator); } }; #include <chrono> #include <iostream> #include <thread> using namespace std::literals::chrono_literals; int main() { Statistics Client; std::cout << "Rate: " << Client.sampleRate() << std::endl; Client.activate(); std::this_thread::sleep_for(5s); Client.deactivate(); std::cout << Client.sampleCount() << ": " << "mean=" << Client.mean() << ", variance=" << Client.variance() << ", min=" << Client.min() << ", max=" << Client.max() << std::endl; } -- Happy patching (pun intended), ⡍⠁⠗⠊⠕ | Blog: <https://blind.guru/> GitHub: <https://github.com/mlang/> .''`. | Twitter: @blindbird23 FaceBook: disyled : :' : | SoundCloud: <soundcloud.com/mario-lang> `. `' | YouTube: <youtube.com/user/mlang23> `-

Anyone working on software implementation of Ravenna for Linux?

by Bearcat Şándor

Has anyone encountered any work on this? How powerful of a computer would be required for a software based solution to be able to keep up with a (expensive for now) ravenna card, if one wanted full channel count at full data rate? I understand that it travels over an RJ45 port with standard wiring (cat 6). I assume one would want an additional dedicated ethernet port for this. I'm considering learning C just to take this on. Thanks

Faust plugin GUI

by Yassin Philip

Hi! I followed up along the "Plugin Programming with Faust" minilac16 conference/workshop <https://youtu.be/T_1Cobmpc5o> by Albert Gräf, and now my dream percussive "kik" plugin is nearing completion :) I'm now wondering how to make a nice custom GUI, something sobre and classy with maybe a logo ; I'm using QT5 for the generic GUI as this is what Albert used in his (quite wonderful I must add) workshop, but I'm not set on it. At the end of the workshop, Albert shows off the "exercise06" plugin (exactly here <https://youtu.be/T_1Cobmpc5o?t=1h18m2s>) and for the first time the UI is not generic but custom, but I can't find the corresponding code anywhere, and believe me I searched :( Can somebody point me in the right direction? yPhil PS - I had to make some adjustments to follow the workshop : 1-the faust-lv2 repo is now at bitbucket <https://bitbucket.org/agraef/faust-lv2> and no longer at github like Albert says in the video (this one was easy) and 2-the included *.cpp files errored, so I had to use the ones from the main faust repo <https://github.com/grame-cncm/faust>. -- Yassin Philip New album NOW http://yassinphilip.bitbucket.io
