Any recommended USB Speakers?

by Andrew Kelley

I don't understand why speakers are using the analog output cable for sound. How about, use a digital interface like HDMI or USB? Can anyone recommend high quality speakers I can purchase which use a digital interface to my computer?

LAC2015 Aftermath: The LAC2014 Percussion Combo Kit now available

by Frank Neumann

[The posting to LAA is awaiting moderator approval for 2 days, so I take the liberty of cross-posting] Hi, during LAC2015 in Mainz last week, I gave a lightning talk on what I called "The LAC2014 Percussion Combo". It was a presentation about a little field recording session conducted one year earlier, during LAC2014 in Karlsruhe, and what I made out of it. The data is now finally online, including the actual sample library kit (individual wav files) with a mapping file for Hydrogen, a tiny demo pattern, and a demo song called "That's LAC" that came to life "out of nowhere" - well, I guess I'll simply call it my first Linux Audio "release" ever :-). Read all about it here: http://linuxaudio.de/wp/?p=158 Thanks go out to the individual artists whose performance I had the honour to record: Marc Groenewegen, Pjotr Lasschuit, Nils Gey, Bernard Tressol, Michael Seeber, Stefano Pedrinazzi, Marie-Kristin Meier, and Fernando Lopez-Lezcano. Enjoy, Frank

Re: [LAD] [LAU] Linux Audio Berlin user group

by David Runge

Excellent. The less mailman to configure for me on Debian-based systems, the better! ;) May 6th sounds good! Any thoughts on what time? I suppose early evening? 8PM okay? So many new mailing lists with interesting topics as of late! I just subscribed to the one you mentioned below. What are your DNS issues exactly? Zone file/ MX record related? Seems okay from the outside (if you host your stuff on gandi exclusively): host -t MX linuxaudio.berlin linuxaudio.berlin mail is handled by 50 fb.mail.gandi.net. linuxaudio.berlin mail is handled by 10 spool.mail.gandi.net. See ya soon, hopefully.

Linux Audio Berlin user group

by Bruno Gola

Hello! There were lot's of Berliners at LAC 2015 and after talking to some of them we thought it would be nice to start a linux audio user group here in Berlin. This is an open call to all Berlin based Linux Audio users and developers! Let's meet, talk and share knowledge :) So far we have a mailing list[1] and an empty twitter account[2] (thanks to Sam :)) Our first meeting will probably be held at C-Base in the next weeks. We have no agenda yet, everyone is welcome, but me and Sam are more focused on electronic music stuff. Any suggestions on the date? [1] (as soon as the DNS starts working properly we send you the link to subscribe) [2] http://twitter.com/LAudioBerlin Cheers! -- Bruno Gola <brunogola(a)gmail.com> http://bgo.la/

Re: [LAD] [LAU] GuitarSynth and polyphonic pitch estimation

by Gerald

Ok issues are fixed. I was sure that something like it exists, as aubio has it. I want to take this thing to be polyphonic, Ideally split up into polyphonic guitar to midi lv2 and maybe synth plugin that somehow apeals to guitarist (I know that vague, but i'm thinking of a synth thats piped through guitarixcab for that nice tube sound). But the emphasis will be the polyphonic audio (actually only guitar) to midi. The other stuff I wrote just not to have to deal with lv2 standard for now. And wavetables are easy and fun. I've done some research and the polyphonic pitch estimation falls under the wider topic called Blind Source Separation (BSS). Is there any expert on BSS here on the list?

Jack1 and Fl::lock

by Aurélien Leblond

Hi, I have been debugging an issue in Giada where sometimes it would get disconnected from Jack1 at start (not Jack2). During my debugging, I found that the JackSyncCallback method setup in Giada's jack_set_sync_callback uses Fl::lock which blocks the main process and Jack doesn't like that. I believe that's what the problem is (especially as after removing them I cannot reproduce it anymore)... Does anyone who knows Jack much better than I do (in fact I'm a real noob in that area) think I'm right in my investigation's finding? Thanks in advance, Aurélien
