[Consortium] What hardware is actually used by freebob/ffado users?

by Pieter Palmers

[Appologies for the cross-posting] [Please DON'T use reply-to-all to reply on this email] Hi all, With this I'm hoping to gather some data that can help us in convincing the firewire device manufacturers that we are of some significance to their sales (I'm actually wondering if we are...). So I would like to ask everyone on these lists that has/considers/considered purchasing a firewire audio device if they would be so kind as to answer the following questionnaire. ** Those that have bought one or more firewire devices... * can you provide which device(s), preferably with their GUID (can be found out using gscanbus or sometimes on the device itself) * Do they work with linux? ** Those that considered buying a firewire device: * What device(s) did you consider buying? * What device did you go for in the end (if applicable)? * To what extent was the lack of Linux support a determining factor in your decision? ** Those that consider buying a firewire device: * What device(s) are you consider buying? * How important is Linux support for you? ** any comments? It would be nice if you would reply to this email with the answers inlined with the questions. Please don't reply-to-all but reply to pieterp(a)joow.be in order not to spam the mailing list with these answers. It would also be nice if you left the subject line intact such that I can auto-filter these messages. Again, sorry to bother you guys with this, but it's a bit difficult to convince manufacturers without some decent data. Thanks, Pieter Palmers ffado.org PS: If you know other freebob/ffado users that are not subscribed to these list please pass this mail on.

[Consortium] latest developments

by Ivica Ico Bukvic

Hi all, Here's a quick update regarding latest developments: Last couple months have been incredibly busy. One of the things I've been working on is getting us a dedicated high-bandwidth access. Since the release of UbuntuStudio our server has been running steadily at 110% of network bandwidth utilization. Thanks to the hard work of our volunteers the server has not melted (yet, :-). This week, I've had already half-dozen meetings (whenever I am subjected to such a torture, I feel as if my IQ has irreparably dropped ;-), some of which pertained directly to the aforesaid predicament. At this point I am unable to promise anything but as long as everything goes as planned, as early as this fall we may be able to move our server to a dedicated Internet2 node (meaning practically guaranteed 100MB+/second connection). Our more immediate plan is to replace the existing server with a dedicated Linux box which would run off of a dedicated 100mBit connection. So, let's keep our fingers crossed! I have been getting steady stream of questions about Linuxaudio.org's participation in various conferences. Given that we are still unable to generate revenue, I am wondering if we could organize a group of Linuxaudio.org ambassadors who, whenever they would participate in various events/conferences/expos, would also do some PR for us. If interested, please contact me asap. Please also mention event you are interested in covering so that we can minimize overalp. Since I believe in leading by example, I have already made plans to cover this year's ICMC which is going to take place in Copenhagen next month ;-). If any of you plan on being there, please make sure to look me up, so that we can go for a pint or two. So much for now. Stay tuned for more updates!

[Consortium] Updates and new stuff

by Fons Adriaensen

Hello all, Some updates and new things on my webpages. First official release of jconv. Jconv is a command line jack client performing FFT-based convolution using a mix of up to five partition sizes, small ones at the start of the IR, and building up to the optimum size further on. It allows zero-delay convolution with moderate CPU load. Jconv uses the multi-threaded convolution engine developed for use in Aella, a convolution engine optimised for reverb processing that is nearing completion. Main features of jconv: - Any convolution matrix up 64 by 64, as long as your CPU(s) can take it. - Allows to trade off processing delay to CPU load, and remains efficient even when configured for zero delay. - Reads the same config files as Jace which it will eventually replace. The beta version released two months ago to some volunteers contained a bug discovered and patched by Martin Rumori. It did not affect configurations using independent 1-to-1 convolutions, only matrix operations. Update of Ambdec Some small changes and bugfixes. The configuration format now also permits the use of mixed-order de- coders (2nd order horizontal, 1st order vertical). Manual updated. TetraProc / TetraCal. Both are ready and have been used for real Ambisonic recordings, but release of TetraCal awaits a required update of Aliki, and completion of the manual that describes the calibration procedure. If you want to use Core Sound's TetraMic with TetraProc this is possible today. I signed an NDA with Core Sound giving me access to the impulse response measurements performed by Core Sound on each mic. Given the serial number, I can process these using TetraCal and provide a matching config file for TetraProc. You can see some examples of this on the updated screenshots page for TetraProc. As usual: <www.kokkinizita.net/linuxaudio> Ciao, -- FA Follie! Follie! Delirio vano è questo !
