Re: [LAU] Linux Audio 2012: Is Linux Audio moving forward?

by Ben Loftis

I'd pose a different question: Is OSX/Win Audio moving _backward_? If OSX continues to move towards iOS, and Win continues to move towards Metro, and Thunderbolt stalls, and screens get smaller, and expansion ports get scarcer, then Linux might become the de-facto "pro" multimedia platform simply because the other choices have become too dumbed down. Of course _most_ users will be happy with the ease and power of the tools that will be available on iOS/Metro. And _most_ users is where the money is, so Apple/Microsoft are chasing the right users. But there will be some serious users that need a powerful production system with big screens and big peripherals, and for these users, Linux might become the standard. -Ben

[LAU] [ot] Data recovery

by Julien Claassen

Hello everyone! I'm sorry to post this here. I've just deleted two days worth of recording work by accident or lack of concentration. It has just happened. Any trick to get the files back. I think, nothing should have been written on the partition yet. It's mostly .wav-files, so I can't just grep the device file for the partition for some text. The computer has one more partition, but it's smaller, so methods, that require a full image of this partition are out. Thanks for any advise! and kind regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html

Re: [LAU] Fairlight

by Len Ovens

I wonder if one was able to make their own MB and start with the kernel and only add what is needed to make audio work. Stay away from fancy video tricks... or add a second cpu for just that... separate memory buss everything. No X, no DE, login would only lock the input devices.. The linux part could well be an off the shelf kernel and core set of utilities... where they can say "yes here is the version we use it is stock <whatever>." The important stuff could still be all proprietary.... or not. I think it could be interesting to build a system that does one thing really well and _nothing_ else. In a desktop system we want the USB port to be usable by the system in linux, but what if we were to set one up to talk directly to wine? It's all in the details. These guys seem to have the resources for taking care of the details. It would not surprise me to find out they were using a slower CPU than most of our desktops. I have been surprised at what I can do with no X and just using Jack and NAMA on a pentium at 300Mhz... Not much ram. -- Len Ovens www.OvenWerks.net

[LAU] Hardware Midi from Wine

by Brent Busby

Up until now, I've never really done much with Midi in emulated Windows apps because I haven't needed them, but recently I acquired a copy of SoundDiver 3 for Windows from just before Apple killed them (jerks!). It's widely regarded as the only Midi patch librarian/editor for hardware synths that ever actually worked. Before I go resorting to a Windows laptop to run it though (which will almost guarantee that I'll seldom use it), I wanted to see if I can get it working in Wine. It seems remarkably well behaved. Actually the only thing that ever crashes it is actual attempts to contact the hardware over Midi -- you can get around in the program and do just about everything else. This seems to have been the issue in just about every other studio app I've ever tried to run in Wine also. For interconnects, I have four hardware in/out pairs: the in/out provided on the RME Multiface II, plus an Edirol UM-3EX provides another 3 in/out pairs connected by USB. I mostly use the ports on the UM-3EX, and they all work fine in Linux under bare Alsa, and in Jack. Also Java apps like JSynthLib can use any of my hardware Midi ports fine also, which is significant because Java provides its own handlers for Midi which must work for that to happen. But Wine seems to be having some problems. All these devices do show up in Wine configuration, and Windows applications also do show them in their menus. Wine comes to a screeching halt when I try to use them. Any recommendations? I notice that Wine also has a Jack driver in addition to the Alsa driver (though it doesn't seem to list any Midi devices...perhaps I need to map them in QJackCtl to make them show up?). Should I be trying to use Jack Midi instead of bare Alsa? -- + Brent A.

[LAU] Announcement: Folve, a FUSE filesystem that convolves audio files on-the-fly

by Henner Zeller

Hi, I'd like to announce Folve, a FUSE filesystem that convolves audio files as they are accessed. https://github.com/hzeller/folve#readme It contains some examples to try right away. If you want to filter your audio (for effect reasons, such as adding reverbs, or just to linearize the frequency response of your speakers), but your system doesn't provide a way to do this while playing, your only option was to pre-process your audio files accordingly. This is time- and disk-consuming, and you probably wouldn't do it just for the fun of adding a reverb. Folve solves this problem: it provides the audio files readily convolved as you access them. It also provides a simple HTTP UI to switch between filters. Right now, Folve is tested with FLAC files; other audio file formats do work, but not all work well with streaming. This is the first public announcement on the announce/user list, but Folve should already pretty usable. Please report problems and feature requests through the github issue tracker. -henner

[LAU] jcgui update to 0.8

by hermann meyer

Hi As of 2011-01-16 I have skipped the development of jcgui, and still I wouldn't maintain/develop it any longer. But it get downloaded and used by some users and I receive requests and bug-reports for it. So I decide to fix the most related bugs and upload a new version, to get rid of that. * fix file not load when white space in path * fix resampling (use zita-resampler now) * fix build with gcc 4.7 * various small fixes Still, I wouldn't recommend to use jcgui, please use IR_LV2 instead, but, if you really would use jcgui, please update it. http://sourceforge.net/projects/jcgui/files/jcgui/jcgui-0.8.tar.bz2/download regards hermann
