So, I'm trying to build Smack, which needs Om, which needs libgnomecanvasmm, which my os (Fedora Core 3) doesn't seem to have, so I found it here: http://sunsite.mff.cuni.cz/MIRRORS/ftp.gnome.org/pub/GNOME/sources/libgnome… And when I try to build it, I get this: g++ -DHAVE_CONFIG_H -DG_LOG_DOMAIN=\"libgnomecanvasmm\" -I../../libgnomecanvas -I../../libgnomecanvas -DXTHREADS -D_REENTRANT -DXUSE_MTSAFE_API -I/usr/local/include/libart-2.0 -I/usr/include/gtkmm-2.4 -I/usr/lib/gtkmm-2.4/include -I/usr/include/glibmm-2.4 -I/usr/lib/glibmm-2.4/include -I/usr/include/gdkmm-2.4 -I/usr/lib/gdkmm-2.4/include -I/usr/include/pangomm-1.4 -I/usr/include/atkmm-1.6 -I/usr/include/gtk-2.0 -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/lib/gtk-2.0/include -I/usr/X11R6/include -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/freetype2/config -I/usr/include/atk-1.0 -I/usr/include/libgnomecanvas-2.0 -g -O2 -MT line.lo -MD -MP -MF .deps/line.Tpo -c line.cc -fPIC -DPIC -o .libs/line.o In file included from line.cc:3: ../../libgnomecanvas/libgnomecanvasmm/line.h:374: error: extra qualification ignored ../../libgnomecanvas/libgnomecanvasmm/line.h:375: error: explicit specialization of non-template `Glib::<anonymous class>' ../../libgnomecanvas/libgnomecanvasmm/line.h:375: error: an anonymous union cannot have function members ../../libgnomecanvas/libgnomecanvasmm/line.h:378: error: abstract declarator `Glib::<anonymous class>' used as declaration make[4]: *** [line.lo] Error 1 make[4]: Leaving directory `/home/scameron/software/libgnomecanvasmm-2.6.0/libgnomecanvas/libgnomecanvasmm' make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory `/home/scameron/software/libgnomecanvasmm-2.6.0/libgnomecanvas/libgnomecanvasmm' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/scameron/software/libgnomecanvasmm-2.6.0/libgnomecanvas' make[1]: *** [all] Error 2 make[1]: Leaving directory `/home/scameron/software/libgnomecanvasmm-2.6.0/libgnomecanvas' make: *** [all-recursive] Error 1 [scameron@zuul libgnomecanvasmm-2.6.0]$ Anybody know how to get around this...?

[linux-audio-dev] IR FFT smoothing

by Andrew Gaydenko

Hi! Trying to understand some magic with Ipmulse Response, FFT and so on, I'm playing with scipy, matplotlib (and python as new language for me as a bonus). Concrete IR was got with help of DRC (rec_imp, saying more strictly). Currently I have got this frequency response graph: http://gaydenko.com/mix/needSmooth.png And the question is: what is common way to smooth the result? Some offtopic apps has something like "1/24, ..., 1/3 octave smoothing". What does it mean? Andrew

[linux-audio-dev] What valgrind says

by james＠dis-dot-dat.net

Hi peeps. I've just been running an app through valgrind and I'm getting a few of these: ==11955== Syscall param write(buf) points to uninitialised byte(s) ==11955== at 0x4D51BDB: (within /lib64/libpthread-2.4.so) ==11955== by 0x4B27CDD: (within /usr/lib64/libjack.so.0.0.23) ==11955== by 0x4B29434: jack_deactivate (in /usr/lib64/libjack.so.0.0.23) ==11955== by 0x4B2945F: jack_client_close (in /usr/lib64/libjack.so.0.0.23) ==11955== by 0x40402F: jackpart_close() (jackPart.cc:86) ==11955== by 0x40235F: mainLoop() (sampleplayer.cpp:438) ==11955== by 0x40237B: main (sampleplayer.cpp:444) ==11955== Address 0x7FEFFE934 is on thread 1's stack I can't see anything wrong on my part, so I thought I'd check with people who know more than I before I tear my program apart. I also get them coming from jack_port_register, jack_activate and jack_connect. Any ideas? James

I can appreciate this modularity as much as the next fellow, but having effects support in the sampler itself is near-critical. Creating sophisticated sounds using a sampler requires it. I need to have multiple layers of samples, each filtered and modulated differently. You can't do this in post-processing. It just isn't possible. Even supposing Linux Sampler could route sounds out to effects and back in to the sampler, that would be far to complicated to be even remotely usable without giving up huge amounts of sampling felixibility. This is not about applying reverb to a drum kit. It's about having 6 samples triggered when I press a key on the keyboard, and each sample being filtered, pitch bended, saturated differently, and modulating all of those parameters using LFO's, envelopes, and midi parameters. You can't do that using "outboard" effects. -Forest

[linux-audio-dev] [OT] No-one was ever fired for having hired FA

by Fons Adriaensen

Hello all, I finally took the big step and handed in my resignation at my employer, Alcatel Alenia Space. After 3 years of CAD, 3 years of real-time kernels, and 11 years in space telecoms, I want to return to my first love which is audio, acoustics, and music. My activities in LAD have certainly contributed to this desire. It will be at least end of september before I really say goodbye at AAS, and I have at this moment no idea at all which way I will go. Which means I'm open to suggestions. I will consider 'a real job' if it's related to acoustics, audio engineering, ambisonics, electro-acoustic music etc. For this type of thing I'm also prepared to move to France, Germany, and any of the European countries bordering the Mare Nostrum. I speak Portuguese (needs refreshing), I am currently learning Greek, and if necessary I'll add Spanish or Italian. I'm not really looking for a job as a programmer. The alternative is of course free-lance consultancy work. And if all else fails, I will be raising sheep on Crete. Anyone interested or having interesting pointers please contact me off-list. (and no, I'm not quitting LAD :) -- FA Follie! Follie! Delirio vano e' questo!

[linux-audio-dev] [ANN] Aqualung 0.9beta5 released

by Tom Szilagyi

Aqualung: Music Player for GNU/Linux http://aqualung.sf.net Release 0.9beta5 It is our greatest pleasure to announce the fifth official beta release of Aqualung. Some features you'd rarely stumble upon in other players (at least not too many of them at once): * Gapless playback (designed for this from the ground up) * High quality decoders (eg. libMAD for mp3), many supported formats * High-quality sample rate conversion support via libsamplerate * LADSPA support * Music Store for organizing your music * And much, much more... We hope you will enjoy this release. The release ChangeLog follows below. 2006-06-30 Tom Szilagyi <tszilagyi at users dot sourceforge dot net> * Aqualung 0.9beta5 http://aqualung.sf.net This is a new milestone release after 17 months of silent development. Large parts of the program have been rewritten, refactored, fixed, etc. A multitude of new features have been added to the software, which now weighs into Open Source with about 30,000 lines of GPL'ed source code, all written by a handful of free-time developers (no, you won't need your whole hand). It won't make too much sense to precisely list every change made to the sources during this period - the list would be prohibitively lengthy. For the curious, the mailing list archive is recommended. The most important, high-level changes are summarized below. * Group CDs in the Playlist via "Album mode". Shuffle between records but play their contents in order! * Statusbars in Playlist and Music Store display statistics and other data. * Multiple Music Stores are supported - useful for separate genres, file formats or for music mounted from different file servers via NFS. * CDDB support! * iFP driver support for integrating with iRiver HW players! * Completely reworked Settings dialog, the new control center! * Embed Playlist into Main window for a more compact look! * Search facility for Music Store and Playlist. * Add support for Musepack (via libmpcdec), Monkey's Audio, Ogg Speex. * Rudimentary album art (cover display) support. * RVA-related work, improved metadata support. * Fixed a boatload of bugs concerning cyrillic filenames, etc. * MP3 improvements (file recognition, clipping, seeking...) * Better fault tolerance in Ogg Vorbis decoder. * Various GUI fixes, new command line options, etc, etc. * Improved build system for skins, icons, etc. * New skins (Ocean, Plain), new Logo (see About box)! ;-) * Better RT behaviour with Jack output. * Compiles and runs on AMD64 (thanks to Mark Knecht for testing)!

[linux-audio-dev] Envelopes

by james＠dis-dot-dat.net

Hi peeps. I've been writing an app that requires volume envelopes. I've implemented the envelope part myself, but I was wondering if there was a library about to do it. I ask because I realised that probably everyone on this list has written something that uses envelopes, and probably written it better and with more features than I have. More generally, is there a library/toolkit of audio bits and bobs about? James

Re: [linux-audio-dev] fst, VST 2.0, kontakt

by Forest Bond

Thanks for clarifying the licensing issues. I think I knew that at some point. What are the odds of changing the FST license to GPL-with-exceptions? > what parts of the full 2.0 spec are you thinking about? Ack. You got me; I don't know enough about the spec to have an answer. But Kontakt doesn't save it's state when asked nicely by any linux VST host I'm aware of. I'll start by trying to fix that. > > There doesn't seem to be any tutorial-type documentation reguarding VST. > there isn't. the vst-plugins mailing list is full of people endlessly > seeking clarification of different aspects of the API. nobody has > definitive answers. I had feared this. To make matters worse, I've not done any serious audio development before. Bits in, bits out, though, isn't it? :) -Forest

The scripts were never intended to be used by a large audience (large by any standard), however, if there is popular demand for them, we might just post them to the website so everyone has easy access to it. We anticipate that this aspect of Aqualung (ie. mass import, mass tagging, etc) will improve greatly by the time we release our next beta. Tom
