To improve Linux audio tools: a Blender like idea

by Grammostola Rosea

Hi all, I'm pretty impressed by the work and way of organization by the Blender Foundation. http://www.blender.org/ http://durian.blender.org/ They use open video projects to improve their 3d software. And those projects looks pretty professional. The movie is even shown on the main film festival in The Netherlands and the project got attention on some big tv programs in at least The Netherlands. Maybe this concept could be useful to improve and promote Linux audio tools too. For example: - contact a professional record label/ studio to make a record only made with FLOSS software - contact professional musicians/ bands/ - contact professional mixing/mastering engineers. - make a cd and some live gigs/touring - make money by sponsors/funds/donations I think those 'professionals' doesn't have to be Linux musicians in my opinion, but good musicians/ engineers in the first place. Of course they should have interest in the project. and of course some expert in the Linux audio community could join such a project. The project could be managed by an Ardour team and/ or Linuxaudio.org for example, like the Blender Foundation is managing the open movie projects. At the end of such a project: - you have a nice cd and maybe some nice gigs (on festivals) - you show the people what is possible with FLOSS audio tools and so you promote it - the audio software tools has been improved to get the project done. Kick off next LAD conference? Regards, \r

balanced xlr to stereo line in

by Jari Suominen

Hi, Just wondered if it would make sense to wire a xlr cable to stereo line in of a computer by connecting the hot and cold rails to left and right channels and decode this balanced signal to mono signal in software. Would that make sense? Has anyone already done simple jack app that would make this or should I have a try on this? br, ....j

Looking for update on ALSA bugs ??

by William Case

Hi; On Aug 4-5 I started a short thread on a problem I am having with ALSA. The thread was http://lists.linuxaudio.org/pipermail/linux-audio-user/2009-August/061871.h… titled [LAU] ALSA + Intel HDA + (Hauppauge PCIe Combo tv tuner) ?? I have also filed a couple of bug reports with Fedora 11. When I check the Fedora Bugzilla page I can see there is a long list of unresolved ALSA bugs. I have also noticed that Ubuntu users are having the same or similar problems. I have received no feedback from anyone on any of this. I am trying not to carp, but simply enquire. Does anyone know? Is there a particular problem with PCIe; analog sound; cx23885 driver; a lack of maintainers; or, a lack of interest in my kind of TV tuner/sound problem? I am trying to decide between being patient, or, throwing out a brand new $150 tv tuner and buying a different one. -- Regards Bill Fedora 11, Gnome 2.26.3 Evo.2.26.3, Emacs 23.1.1

Yes, that's it - at least on a very, very basic level. Miller's patch for guitar is one very advanced beast showing some very cool and cutting edge synthesis methods. It's not your run-of-the-mill guitar effects processor. In fact it make me want to be able to play guitar. :) > Might be a good idea to avoid latency > because of the pitch detection, but not a big difference to effect > processors for normal pickups. It does pitch detection inside of Pd to tune the transformations to the pitch played, so you still get a bit of latency (pitch detection is made on blocks of 1024 samples afaik.) > Hm, I didn't read the link ;) Maybe you'd want to? Here's the deep link: http://crca.ucsd.edu/~msp/smeck/latest/doc/ and the pd~convention paper: http://crca.ucsd.edu/~msp/Publications/pd07-reprint.pdf rsp. http://crca.ucsd.edu/~msp/Publications/pd07-reprint.dir/ Ciao -- Frank

For > someone just in to looping... FW gives a nice and fairly intuitive GUI. No > sync options, a MIDI implementation out of the box, etc. Let me first say that I really like FW's approach to multiple simultaneous loops. In many ways I wish SL had a different design than it ended up with. Not needing to care a priori about the loop count is really nice. As for a MIDI implementation out of the box... doesn't that just put the burden of configuring your hardware to match it? I find that setting/changing the bindings in SL (especially with midi learn) to be a bit easier. I could easily include a selection of default midi binding presets with SL, if I thought there was some common setup that would actually be useful to people. Feel free to send me some! > Also, there's a lot of overhead in adding a new loop with slgui. Each new > loop takes up a lot of screen space... and takes extra planning and abstract > thought to set it up with a midi controller of some sort. Indeed, that was the point of my previous comment, if you aren't going to actually use a mouse on the SL GUI, then there should be a performance mode that does away with all of that. As for the abstract thought to set up a midi controller, you might want to look into bindings that make use of the "selected" loop, that way you can jump between selections with some bindings (specific loop, or next/prev) then set up all your other commands to be bound to the selected loop. Some as yet unreleased new features actually make the record_or_overdub command even more suitable for "one button looping"... if there is nothing in the loop it starts Record, then stops record.... then when hit again thereafter it starts/stops Overdubbing on that loop. Do a double tap and it does an Undo. Hold it down (a long-press if you have note-like bindings with separate press/release ability) and it clears the loop. If record and overdub covers your looping, you could just set up a button on your controller for each loop bound to this. Look for it in the next release. jlc

[PD-announce] smeck (6ch guitar processing patch) released]

by Frank Barknecht

Hi, something for the guitarists around. This is the patch, that Miller Puckette explained during the workshop at LAC2008. Ciao -- Frank ----- Forwarded message from Miller Puckette <mpuckett(a)imusic1.ucsd.edu> ----- Date: Mon, 24 Aug 2009 20:52:33 -0700 From: Miller Puckette <mpuckett(a)imusic1.ucsd.edu> To: pd-announce(a)iem.at Subject: [PD] [PD-announce] smeck (6ch guitar processing patch) released Hi all, I've finally done a good enough job of cleaning up the 'smeck' patch (seen at Pd conventions 2007 and 2009) to consider it releasable. This patch takes a 6-channel signal from a separated guitar pickup (such as the Roland GK series) and does a variety of cool things to it. Smeck is available from: http://crca.ucsd.edu/~msp/ cheers Miller _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce _______________________________________________ Pd-list(a)iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list ----- End forwarded message -----

Strange sound file

by Eugen Dedu

Hi, I do not know much about audio. The "newmessage.wav" file from http://git.gnome.org/cgit/ekiga/tree/sounds is strange because it is correctly played by aplay, vlc plays it but not the same thing is heard, and xmms does not play it all. Standard windows programs do not play it either. Could someone tell me what's special with this file? Thanks, -- Eugen

This was what I > did. what possible relevance does this have to LAD? miller puckette made something possible, and you sounded to me as though you were complaining that what he did was a bad idea because it doesn't fit in with your ideas of aesthetic creation. i have my own ideas about good and bad and terrible ways to make music, and the results thereof, but i generally try to keep this to myself, and certainly keep it off LAD. i found your commentary on miller's work rude and insulting, both as a wannabe musician and as a developer of FLOSS. if you are not interested in what he has done, then just don't bother to comment upon it. of course, i may have misread your comments.

"Smeck" is not for midi, but for audio pickups. You need a separate pickup for each string. Ciao -- Frank > Frank Barknecht wrote: > > Hi, > > > > something for the guitarists around.
