-ck patch

by Raffaele Morelli

Hi you all, what do you think about that? Have you got some personal experience? http://ck-hack.blogspot.com/2010/10/bfs-in-real-time.html Regards Raffaele -- *L'unica speranza di catarsi, ammesso che ne esista una, resta affidata all'istinto di ribellione, alla rivolta non isterilita in progetti, alla protesta violenta e viscerale.*

Realtime latency kernel testing

by ailo

I've been looking around for any tests made comparing the different kernels, -rt, generic, or any other type of realtime enchanced kernel. I haven't found any test results yet, at least none audio related. I did find some testing tools at rt.wiki.kernel.org, but don't know if and how they could be made relevant to audio low latency testing. I suppose the most interesting results would come from testing different kernels with jack/alsa and jack/ffado. Has anyone done such tests? -- ailo

New release of zita-at1

by fons＠kokkinizita.net

An update of zita-at1 is available at the usual place: <http://www.kokkinizita.net/linuxaudio/downloads>. Changes: * The resampler now uses cubic interpolation (at twice the sample rate for 44.1 and 48 kHz), giving even cleaner output. * The offset control now has 400 steps of exactly 1 cent (1/100 semitone) each, and displays the set value when touched. Default mousewheel step is 10 cents, 1 cent with Shift pressed. Enjoy ! -- FA There are three of them, and Alleline.

two new songs

by Dave Phillips

Greetings, I've posted two new songs on my site. Both are rough mixes prepared for my band, but I figured I'd post them anyway until I find the time to do a more decent job. Yes, the second song has some tuning discrepancies, and yes, I'm really that lazy. Notes from my page at http://linux-sound.org/ardour-music.html : Here in Ohio USA we have an interesting law that requires a convicted drunk driver to put specially-colored license plates on his or her vehicle (assuming s/he's still allowed to drive, of course). Law enforcement officers can easily spot such plates, and of course everyone else gets to cast humiliation on the idiot who decided to drink and drive. The following song is dedicated to my foolish neighbor who managed to fall afoul of the authorities, winning himself some brightly colored tags for his truck. Hilarity ensues. http://linux-sound.org/audio/Orange_Plates.mp3 Okay, so much for the poor unfortunate Floyd. The next song was inspired by none other Rusty Campbell, my good friend and fellow musician, who also happens to play drums in my band. Strange to say, this song has become a crowd-pleaser and is one of our most-requested tunes. Of course it isn't /really/ about Rusty (a.k.a. El Viejo). The poor fellow was just minding his own business, then he gets hit with this assessment. Inspiration can be so cruel. http://linux-sound.org/audio/drummerinabluesband.mp3 Lyrics are on the page mentioned above. Happy holidays to all ! Best, dp

And even more organ music

by Julien Claassen

Hello all! So here's some more from the organ and me. Oh, I forgot to mention: It's a small instrument in a local church here. This time recorded from directly behind me. The first take was done from the viccar's lectern. The organ has five stops (gedackt 8ft., principal - probably 8ft. but sounds like 4ft. -, Rohrfloete 4ft., Waldfloete 2ft. and two mixtures - for each half of the keyboard and a 16ft. subbass, which sounds like gedackt 16ft.). http://juliencoder.de/jb/xmas_10 The files endng in_close are the new ones. There's also the b minor prelude, which I didn't take from the other session. All files are available as ogg and mp3. Enjoy! Merry Christmas or wonderful holidays (whatever you prefer) Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

Till now people seems to be positive about SSD for audio data. More and/ or different views on this? Best regards, \r

PD L2Ork 20101229 snapshot now available

by Ivica Ico Bukvic

Please excuse cross-posting. Dear friends and fellow FOSS enthusiasts, It is my great pleasure to share with the community a belated Holiday present :-) in a form of latest snapshot of L2Ork iteration of Pure-Data. Better than ever, the latest version comes with the following improvements: *implemented apply undo for array properties and partially implemented apply undo for graph-on-parent object properties (does not apply to abstractions or top-level windows currently until I figure out how to address the indexing of toplevel windows inside the glist as well as how to address to which window such an undo belongs). *properties are disabled when right-clicking on an abstraction as modifying its settings externally does not make sense when one does not see the actual contents inside it. So, to edit the properties of an abstraction, one has to open the actual abstraction. *fixed how new arrays are created so that they always fit within the specified boundaries. Please note arrays that have been already created in prior patches remain untouched in terms of graph auto-resizing (legacy code is provided in g_editor.c canvas_vis that deals with this if anyone wishes to convert their arrays but is incomplete in that it assumes all arrays require resizing--this is however unnecessary as simple recreation of said arrays or manual readjustment of their settings ought to do the trick. -This feature needs further testing--feedback is most appreciated. *fixed how arrays deal with moving array points via mouse by restricting them within the array bounds--this should work for all gui-driven array operations, while array alterations via snapshots and other external ways of manipulating arrays remain unbound so as to allow for traditional data-flow debugging--this may change down the road in part due to introduction of the magicGlass option and in part due to belief that data monitoring should only report ranges specified by the graph. -This feature needs further testing--feedback is most appreciated. *added new feature for arrays where they report a bang through the <arrayname>_changed send (if one is provided) whenever they have been altered by a mouse click'n'drag--this in conjunction with array graph auto-resizing makes arrays formidable alternatives for multisliders. -This feature needs further testing--feedback is most appreciated. *when an array subpatch is opened and resized, the array automatically now resizes to properly fill the window. -This feature needs further testing--feedback is most appreciated. *fixed where array was not visible after reopening the patch if any of its points touched upon y graph limits. *fixed couple of segfaults caused by gridflow incompatibility--more problems remain with gridflow library compatibility, likely due to widgetbehavior and possibly also magicGlass incompatibility. Further investigation is necessary. *fixed memory leak in the disis_phasor~ external where the destructor was never properly called and updated its documentation (available in the l2ork_addons package). *fixed highlighting of signal nlets where nlet would revert to non-signal appearance after being highlighted/connected. *reintroduced array listview (this was a regression in respect to pd-extended). *improved appearance of the array listview. *fixed a few broken links in the pddp documentation and added new l2ork-specific array features to the pddp documentation. Latest snapshot is available from the usual place: http://l2ork.music.vt.edu/main/?page_id=56 Complete changelog since 11/25/2010 is available here: http://l2ork.music.vt.edu/data/pd/Changelog Happy belated Holidays! Best wishes, Ico
