Greetings, I've just received a notice from the Linux Journal that they will no longer be running my monthly articles. I know that some people on this list have enjoyed reading them, but alas, all things must end. I've been invited to contribute full-length articles to the digital edition, which I will do, but those articles will be available only to subscribers. I have given some thought to collecting all my LJ articles to date (12+ years worth) and posting updated versions at linux-sound.org. However, the work is non-trivial - it takes considerable time to research and write those articles - and I have bills to pay. Other work for hire will necessarily take precedence, meaning I'll probably teach more and perform more often. So, I hope you've enjoyed my work for LJ. Thanks for the reads, I've enjoyed the writing. Best, dp

building luppp

by Atte André Jensen

Hi I'm trying to build our new tow, luppp, on arch, but it fails. I made it past the configure stage, after a bit poking around in aur... As far as I can tell waf can't find lv2/lv2plug.in/ns/ext/event/event.h, and sure enough it's not there: atte@blokhus:~/software/Luppp$ ll /usr/include/lv2/lv2plug.in/ns/ext/ total 0 lrwxrwxrwx 1 root root 38 Jan 17 10:45 dynmanifest -> ../../../../../lib/lv2/dynmanifest.lv2 Any idea which package provides that file?

previewing samples - sample browser

by Alessandro Preziosi (licnep)

Hello, Any idea to quickly preview audio files (using jack)? I have a huge sample library (.wav mostly) and I'd love something like a file browser that previews files when you click them or hover them. Is there such a thing? Even if i have to open a more complex audio application and just use its file browser i'd be ok with that solution.

Paul's Extreme Sound Stretch

by Louigi Verona

Hey guys! Some months ago (a year ago, maybe) I asked on the LAD list if anyoe could JACKify paulstretch. Someone was kind enough to do it and the change was indeed incorporated into the main source. Did anyone actually compile new JACKified paulstretch for Ubuntu 10.04? -- Louigi Verona http://www.louigiverona.ru/

State of RME Raydat?

by Jason Jones

Hello all. I'm new to the list, although I shouldn't be. I've been running a Linux-based recording studio now for 10 years, and doing it professionally for 3. I use ardour, hydrogen, muse2, mixbus, LinuxDSP, and a bunch of OSS LADSPA and LV2 plugins. I recently decided to jump into the RME arena (currently using an Echo Audiofire12 for my converters and interface, and it works beautifully) and am finding it oddly difficult to get good results from google concerning the state of new-ish RME products and Linux compatibility. Has anyone out there used the Raydat interface successfully with the WCM (word clock module) add-on card? Does the hdspmixer work with the raydat? Are there any shortcomings, or any reason I shouldn't use it in a professional studio? I thought it'd be a good idea to refresh the internet new RME info, because the latest update I can find is from September of 2011. Any info is welcome! Thank you! --Jason www.advancedbudgetstudios.com

choir effect

by Renato

Hi, I'm interested in how to create a "choir" effect - given a single instrument playing (I'm personally interested in single drum shots from hydrogen and guitar lines, i.e. not chords), I'd like to have n copies of the signal (where n would probably be something between 2 and 20), each with a slightly different delay, volume, eq, pitch. Is this doable in a sane way, at least in part, with the free tools we have? I think it should be doable in sc or pd, but I was wondering if it's possible with ladspa, lv2 and dssi, and maybe a host like ams or ingen. cheers, renato

QasTools 0.17.0 released

by Sebastian H.

QasTools version 0.17.0 is available. QasTools is a collection of dektop applications for ALSA. Changes: * all: setting names for state save/restore changed/regrouped * all: smart main window sizeHint() to get a useable window size after leaving fullscreen * all: new common info dialog - uses QListView page selection intead of tabs * shared: device selection style tweaks: selected item now emphasized by a thin frame * shared: device selection style tweaks: Rounded selection area * shared: use QSplitter instead of QDockwidget for device selection view. It couldn't be detached anyway and size restoring works more reliable. * qasconfig: settings directory changed to shared ~/.config/qastools/ (was ~/.config/qasconfig/) * qasconfig: new basic command line options (--version, --help, etc.) * qashctl: new basic command line options (--version, --help, etc.) * qasmixer: new application icon Homepage with more information http://xwmw.org/qastools Project page http://sourceforge.net/projects/qastools/ Happy volume changing! -- Sebastian Holtermann
