My jackdbus2 says it is 1.9.9.5. (taken from ~/.log/jack/jackdbus.log) The release notes say "- Add opus support to NetJack2." jack_control ip netadapter Shows: celt: Set CELT encoding and number of kBits per channel (sint:notset:-1:-1) Am I mistaken in my understanding that the jacknet2 backend is a part of jackd? Or does setting "celt" actually now set opus? (the jackd manpage also uses the word celt) -- Len Ovens www.OvenWerks.net

[LAU] GMorgan play along

by Robert Vogel

I subscribe to a free service: Jazz on the Tube <http://www.jazzonthetube.com/> that sends a clip about every day. Here's an example: http://www.jazzonthetube.com/videos/count-basie/slow-blues.html With that inspiration: GMorgan is a free program which you can download from Sourceforge. It works well for me using Ubuntu and a Yamaha Motif ES8 keyboard. Probably it runs on other Linux distributions, although Fedora could not keep time...(I didn't install the correct graphic driver for Nvidia.) You don't have to install GMorgan though. Try playing along with this slow blues in Bb, a YouTube video which is screenscraped from GMorgan0.58. Get your instrument and open full screen. (If the Youtube isn't clear enough drop me a note and I'll send you a link to the original file. I couldn't resist adding some illustrative accompaniment tracks. Watch on the left of the screen for pattern changes. http://youtu.be/R6iHyLcBee0 If you like it. let me know and I'll make some more. Bob

[LAU] Chiptune Accompaniment in Pure Data!

by Louis Gorenfeld

I finally got around to zipping up and releasing my chiptune accompaniment software that I debuted at San Mateo Maker Faire 2012. It's called Chip-o-Matic and it runs off Pure Data. I figured it'd be of interest to people on this list. Plus, it comes with a small document that talks about the history of chiptunes and how they work. Basically, you load it up in Pure Data, and then you can set the beat pattern/arpeg speed/tempo, choose the bass note with the lower octave, play arpeggios with the middle octaves, and play leads with the top octave. It can be gotten at http://extentofthejam.com/Chip-o-Matic-1.0.tar.gz And here's a small thrown-together sample of me noodling with it: http://www.extentofthejam.com/ChipQuickie.mp3 Happy Valentine's Day, everyone!

[LAU] Mastering the meaning of mastering and "original master recording" in the digital age

by Bearcat M. Şándor

Folks, I've got music ripped to my hard drive (hybrid wavpack for the curious), and i'm a little obsessive about my tagging. I've got a 'mastering' tag wherein i put the name of the mastering engineer and whether or not the track is an "original master recording". These original master recordings are usually DCC, Mobile Fidelity Sound Labs or Audio Fidelity labels. So now i'm staring at the rest of my collection wondering what to put in there. These original master recording discs are older (20+ years) when mastering was analog. My questions are: Most recent CDs were mastered digitally, therefore is the original master equivalent (at least in quality) to the CD i own? At about what year did most CDs become digitally mastered, rendering original master recordings moot, if they are? I *swear* i remember buying CDs when they came out and they used to tell you how things were mastered. Didn't they used to indicate AAD, ADD, DDD for (recording, editing, mastering)? Why did they stop doing this? Is there any way to tell/reasonably guess if a CD has been digitally mastered without those codes? Thanks, -- Bearcat M.

Re: [LAU] MICROSOFT HIRED THESE PEOPLE TO SABOTAGE OPEN SOURCE

Please, continue at d-community-offtopic(a)lists.alioth.debian.org only!

This is the OP: Dirk <yqlsxepzrclk(a)mailinator.com> So no real name and picture of this guy. Sure, I've got another point of view myself and don't like those changes for Linux too, for example, when ever possible I try to get outdated versions of GIMP and there are many changes and new policies I don't like. I also don't like many members of the community, but we are humans with different worldviews and even if other people don't tolerate your or my world view, we should tolerate others and not do the same. Denunciation by email to an open list is absolutely unacceptable, for several reasons, e.g. people could have the same name, or look very similar. Your claim suffers from missing evidences! Even if this should be meant as a joke, it could excited people. Even if this should be mean serious, while being the truth, this isn't the way civilized people act. If "MICROSOFT HIRED PEOPLE TO SABOTAGE OPEN SOURCE", then we should talk about it, without witch-hunting. At least fr me it's not important who are those people, for me it's important to know more about this issue. Are there any evidences for your claim? I don't like many changes, because some changes make Linux closer to Windows, but I use Linux to be far away from Windows. Why should Microsoft hire people to make Linux more like Windows? I don't do research about this topic myself, it seems t be a conspiracy theory and not worth the hassle. This is the chance for you Dirk, to undergird your hard claim. Btw. IMO this belongs to http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/d-community-offtopic if we should continue without witch-hunting. Including the witch-hunting it belongs to /dev/null.

[LAU] Skype won't work though JACK plugin

by Joel Roth

Hi list, Redirecting the ALSA default device to JACK seems to be well-traveled territory,[1,2] nevertheless, I'm not getting all the behaviors I'd like. Flash works, but Skype doesn't, and surprisingly Ecasound doesn't do well either (an interesting data point although hardly a problem.) Perhaps Skype is trying to work via /dev/dsp? I'm curious if anyone else is getting better results. Here are my test results: aplay test.wav # plays! aplay -D default test.wav # plays! mplayer -ao alsa:default test.wav # plays! mplayer -ao alsa test.wav # plays! ecasound -i test.wav -o alsa # weird noise after several seconds delay ecasound -i test.wav -o alsa,default # weird noise after several seconds delay Flash/Firefox # plays! skype # "problem with audio playback" I'm running JACK like this: jackd -d alsa -d hw:0,0 -r 44100 -H And I'm using this asoundrc: pcm.!default { type plug slave { pcm "jack" } } pcm.jack { type jack playback_ports { 0 system:playback_1 1 system:playback_2 } capture_ports { 0 system:capture_1 1 system:capture_2 } } Regards, Joel -- Joel Roth
