Hi, As a matter of fact I do. I just forgot to include it in the original email. If you use the promo code AUDIO, you'll receive a 50% discount off a full price pass. Thanks!

LAC2009 paper deadline coming near...

by Fons Adriaensen

Hello all, yada-yada (*) The paper submission deadline for LAC2009 is just a little more than 100 hours away, and the response so far has been rather disappointing, to the point that there would not be much of a conference at all. The deadline could be extended by two weeks (29 Jan, midnight), but that would make sense only if we know there will be sufficient submissions. So if you are planning to submit a paper, or present a workshop please let me know *ASAP*, and in any case before the original deadline (15 Jan, midnight). Ciao, (*) This means 'best wishes for 2009 !' -- FA Laboratorio di Acustica ed Elettroacustica Parma, Italia O tu, che porte, correndo si ? E guerra e morte !

Invitation to Southern California Linux Expo 7x

by Gareth J. Greenaway

Greetings, I hope this email finds everyone doing well. The Southern California Linux Expo is fast approaching and we have a few spots left for free & open source projects. I would like to formerly invite the Linux Audio consortium to participate at the show and showcase the various free & open source audio applications that are currently available. The show will be taking place February 20th - 22nd, 2009 in Los Angeles, CA at the Westin LAX. SCALE would provide a complimentary booth on our show floor including all the usual amenities such as a 500W power outlet, ethernet drop, one 6' table and chairs. We will also provide 3-5 complimentary passes to the show. Ideally we would like to see as many of the Linux Audio member projects represented. Any questions please do not hesitate to ask. Thanks!

LV2 or DSSI version of amSynth

by Jaakko Sipari

Hi! Is anyone planning on a complete DSSI (w/ GUI) version of amSynth or even better, an LV2 version? I'd also be interested to hear if there is anything similar already in the LV2-world? - Jaakko

Audio file audio length

by William Steidtmann

Is there a way to check from the command line the audio length (not the size of the file) of an audio file (assume wav, but I also want to do other types, especially flac). So far I have only found this: sox myaudiofile.wav -n stat which gives me more information than I need, but at least I can parse out the length from that output. Is there a simpler more direct approach using some other command line utility ? Bill

Re: [LAD] Audio file audio length

by Julien Claassen

Hi again! The csound utility is called sndinfo, but it also gives more than you need. I know that the sndfile-* and eca* utilities can handle quite a collection of formats .flac definitely included.

[ANN] DSSI 1.0 release; FluidSynth-DSSI, hexter, Xsynth-DSSI updates

by Sean Bolton

Announcing the DSSI Soft Synth Interface version 1.0 release: http://dssi.sourceforge.net/ DSSI is an audio plugin API for software instruments and effects, based on LADSPA, the ALSA sequencer event types, and OSC (Open Sound Control) communications. DSSI is now supported by six full-featured hosts, several specialized hosts, and at least twenty-two DSSI plugins. (See the above URL for a list.) This release contains one small addition to the DSSI API itself, allowing for communication of the sample rate to DSSI UIs. Since the DSSI API has been stable now (with minor additions) for four and a half years, and since most active interest in further extending a Linux softsynth plugin standard has been absorbed by the LV2 project, it seems appropriate to call this release "version 1.0". In addition to the API addition, code and documentation updates have been made in the DSSI release itself, and in FluidSynth-DSSI, hexter, and Xsynth-DSSI. New versions of each are available at the above URL. Specific changes include: DSSI 1.0.0: * Addition to API of the new 'sample-rate' OSC method. * Addition of a Karplus-Strong example synth. * Documentation improvements. * Updates for newer gcc/glibc, for Mac OS X, and for newer JACK. * Addition of man pages thanks to Mark Hymers and Debian. FluidSynth-DSSI 1.0.0: * Fixed a bug that caused distorted sound when hosted by Aldrin. * Updates for Mac OS X. * Changed GUI to handle (ignore) the 'sample-rate' method. * Added '-test' option to allow testing the GUI without a host. hexter 0.6.2: * Updates for newer GTK+. * Changed GUI to handle (ignore) the 'sample-rate' method. Xsynth-DSSI 0.9.2: * Updates for newer gcc/glibc, RPM-based distros, Mac OS X, and newer GTK+. * Changed GUI to handle (ignore) the 'sample-rate' method. * Added '-test' option to allow testing the GUI without a host. Enjoy! Sean Bolton

GTK jack based apps cant connect to jack ---> debian glibc 2.8.1 + Jackd 0.116.1

by Josep Andreu

Hi I recently update my debian glibc to 2.8.1, and surprise ... GTK based apps can't connect to jackd server, well even Ardour can't start the server, maybe is a debian glibc/gtk issue, or maybe not .... can anyone check and confirm in other distro? btw qt, fltk jack based apps run fine, and other GTK stuff run.

[ANN] libsmf-1.2

by Edward Tomasz Napierala

Version 1.2 of libsmf can be downloaded from the projects site: http://sourceforge.net/projects/libsmf/ LibSMF is a BSD-licensed C library for handling SMF ("*.mid") files. It transparently handles time<->pulses conversions, tempo map handling etc. The only dependencies are C compiler and glib. API documentation and examples are included. It was tested under Linux, FreeBSD, MacOS X and Solaris. Please note that, by default, libsmf is built with lots of asserts, which make it slower; for example, inside smf_save, there is some code that loads the newly saved file and compares it with what it was supposed to save. If some operation takes noticeable amount of time, try to recompile libsmf with -DNDEBUG to disable asserts. API documentation is here: http://libsmf.sourceforge.net/api/ SVN repository is here: http://libsmf.svn.sourceforge.net/ Thanks to Dominic Sacré for help with testing this release. -- If you cut off my head, what would I say? Me and my head, or me and my body?
