First release of jack_export

by Fons Adriaensen

Jack_export is a simple command line app I've been using to do multichannel exports from Ardour2 sessions. Of course A3 provides this OOTB, but I will maintain jack_export to provide (if necessary) formats and options that A3 doesn't or won't support. This release does not include resampling, the sample rate of the exported file will be the current Jack sample rate. To use, proceed as follows: 1. (Optional) In Ardour, create a bus (not a track) named 'export', and containing all the signals you want to export. You can skip this step, in that case you'll have to connect Ardour outputs to jack_export inputs manually after step 2. 2. Run jack_export. See --help for options. The --chan option is mandatory. E.g. jack_export --chan 16 my16channelfile.wav Jack_export will connect to the 'export' bus if it exists, and print Ready ... If you did not create an 'export' bus in Ardour, now connect Ardour outputs to jack_export inputs manually. 3. Do a normal export in Ardour, using some dummy name for the exported file. As soon as Jack goes into freewheeling mode, jack_export will print Recording ... When the export terminates, jack_export will print a completion message reporting the number of seconds recorded. Now available on <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)

IR: LV2 Convolution Reverb and ambisonics

If you use Ardour to create, mix& > produce music, you will most probably want to check out this plugin. It is a great addition Tom, I'm packaging it in Planet CCRMA now. I'm trying to see what is the best way to convert the plugin so that it can deal with first order ambisonics impulse responses. Those are four channels wide (ie: four convolutions, one for each of the four incoming channels - W X Y Z). I managed to get it to work by creating ir-amb.cc, ir-amb_gui.cc, etc, etc. And changing your code to have the required number of ports, etc. It does work, except that my simple minded rewrite breaks down if I try to instantiate a normal IR plugin in addition to the IR-AMB (how I named the "new" plugin). In that case the second instance (order does not matter) bugs out with: (ardour-2.8.12:14284): GLib-GObject-WARNING **: cannot register existing type `IRWaveDisplay' etc (same for IRModeInd and IRMeter, all the gui classes I did not duplicate). I can have multiple instances of either, but not mixed (well, I can, it is just that opening the gui for the second does not work and crashes the rest). Knowing nothing about all the components involved I need some help... I can supply or post the patch if needed (I presume it is some simple gtk thingy I need to add to the code). -- Fernando

SMPTE and jackd

by Egor Sanin

Hi folks. I've got a question about SMPTE frames and jack period size. In the "worst case" of 30 frames/second, each frame spans 1/30 seconds. Does that mean that if jackd is called such that (period size)/(rate) > (1/30) seconds, we will drop SMPTE frames? Large period sizes are rare these days, but this is still a possible scenario and I want to understand it properly. Thanks.

How do I add threadirqs as a default boot parameter for a linux kernel not editing boot configs?

by Kaj Ailomaa

I've been trying to find some docs on how to get the kernel to boot with the threadirqs by default, and not needing to pass that option manually at boot time (or editing a boot config). Or, any boot option for that matter.. Anyone care to shed some light on this? :)

NASPRO 0.4.1 released

by Stefano D'Angelo

Hi all, I am glad to announce the release of NASPRO 0.4.1. NASPRO (http://naspro.atheme.org/) is meant to be a cross-platform sound processing software architecture built around the LV2 plugin standard (http://lv2plug.in/). The goal of the project is to develop a series of tools to make it easy and convenient to use LV2 for sound processing on any (relevant) platform and for everybody: end users, host developers, plugin developers, distributors and scientists/researchers. This is just a small update to NASPRO Bridge it and NASPRO bridges that: * makes use of LV2 Atom for MIDI events; * enables LRDF-equivalent bundle installation and automatic translation of DSSI programs to LV2 presets by default; * aligns with the unified LV2 distribution. Enjoy!

Re: [LAD] Introducing "Open Tritone Midi", a Satanic Open Octave Midi Fork

by Edward Diehl

I feel this whole thread is highly inappropriate and repugnant. If you do not like OOMidi you do not have to use it or support their fundraiser, but this kind of gratuitous baiting is uncalled for. The claims that OOMidi has done no development on their own are rediculous. Sure, have forked Muse, that is acknowledged on their website and code, but it is also clear they have added quite a bit of functionality to the original codebase. Frankly this sort of project is what open source and the GPL is all about - users are free to modify code and scratch their own itch. sincerely, Edward Diehl

Introducing "Open Tritone Midi", a Satanic Open Octave Midi Fork

by Rolf Wolf

My fellow humans, This is the announcement of "Open Tritone Midi", a Satanic DAW and Midi Sequencer. The Tritone is the classic devils musical interval. ( http://en.wikipedia.org/wiki/Tritone ) It will be just an Open Octave Midi fork with replaced Logo graphics and the removal of the current author names. So I don't have to do development myself but I can start funding campaigns. As Satanic Software it is most important to center around humans, so a friendly and humble manner in support, communication and marketing affairs will be the main focus. When it is ready the next mail will be send to this list. *sign of the horns*
