Can you link to an API reference or the like? Hi Chris, The download link is below. The current version is tested on Windows only, I'm pretty sure it's potentially Linux friendly because it's a refinement of the original prototype which was jointly developed with Tim Hocken on Linux. Any MSWindows-specific, or SynthEdit-specific features are implemented as extensions. I periodically check it compiles cleanly with GCC. http://www.synthedit.com/sdk.htm ----------------------------- From: Emanuel Rumpf <xbran(a)web.de> >From the KVR site: "Like MIDI, GMPI will be license free and royalty free." >"...and will cost you ~ $88 to acquire." My addition. >FLOSS people - let's rather ignore GMPI as long as we can. The prototype was developed by members of the GMPI mailing list who are not members of the MMA. "Req 113: The GMPI SDK must be released under a license with similar terms to the BSD license." It is under the BSD license, it costs nothing to acquire or to use. Every plugin I've written with GMPI (aka SEM) is also BSD and source code is available with the SDK. My own plugins are aimed at modular synthesis though, so maybe not widely useful. ------------------------------ I'm don't believe GMPI has much chance of widespread popularity, much of the design was considered too radical, e.g. my proposal to ditch MIDI. MIDI support *was* eventually included as an option, but I also support MIDI-less synths controlled via polyphonic control-ports. I will continue using my branch of GMPI, it's far cleaner, more advanced and more efficient (for me) than anything else. Here are the official GMPI requirements... http://retropaganda.info/archives/gmpi/gmpi-requirements-2005-04-05-final-dr aft.html Here (bottom of page )... list which GMPI requirements are currently supported. http://www.synthedit.com/sdk3_docs/index.htm Jeff McClintock.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm just curious what your long-time experiences with these gui-libraries are. Considering to use one of these two but can't really decide. But I do not want to switch in a year or two... Thanks for your advices!

Re: [LAD] How to develop guis for LV2?

by Jeff McClintock

<insert obligatory GMPI joke here> >-dr GMPI is quietly and successfully in use as the new native plugin format of SynthEdit. I've so far written 70 plugins with it, and others are writing more. SynthEdit's previous plugin format has about 1000 plugins available, hopefully also will be ported to GMPI (aka SEM V3)... so GMPI can't really be called vaporware any more. Jeff

Help to choose an audio library for a project

by Ludovic RESLINGER

Hello, I'm student in computer science and for one of my projects, I would like to program an audio player. The player will be developed for GNU/Linux environment but I would like to use an audio library which permit a portability for Windows and MacOS X too. The player will must read files in wav, MP3 and OGG/vorbis (at first) and it will have an equalizer. I think to use C++ language with Qt library for the graphical interface but I encounter difficulties to make a choise for an audio library, that is why I thought to ask the question on this list. What would be the best audio library to program this kind of audio applications ? (SDL ? OpenAl ? PortAudio? or other(s) ?) Thank you by advance for your answers. Regards, -- .---.

by Machel Sylvain

Hi, I'm about to work on a LV2 wrapper for the FxEngine Framework and I would like to know if it exits compliant tests to validate LV2 plugin according to the port type, scope, ect ..... ? With the exeption of a few unitary tests, I didn't find anything on the web. Thanks in advance, regards, Sylvain

[Maybe OT] Linux Audio Apps Clasification

by Daniel Vidal

Hi I think this post is [OT] but also i think is the apropiate audience... I'am now working on making personalized menus for Musix distro. I try to do this task using the freedesktop rules, using .desktop files and the "Categories" field. This is a real problem. All audio Apps put "AudioVideo" tag... and all apps apear together on a single menu option... Mixers merged with synths... with DAWs... with virtual keyboards... Well... when the user chooses the "multimedia" option of system menu... the submenu have three columns of apps... Only a little set of apps put more specific tag like "Midi" or "Synthesis"... This behavoir can be modified using more "Categories" tags describing more closely the app... But this cant be done without the agreement of linux apps developers about a clasification... I can make a proposal to add some tags? (Tags about types off apps) AudioFX -> Effects DAW AudioAnalisys FftAnalisys AudioFrameworks (like csound or CLAM) AudioPlayer Mixer WaveEditor ScoreEditor . . (Tags about runtime environment) Jack Alsa Portaudio . . If the developers of audio apps include this tags (or others that can be discussed here) the wm developers can make a multimedia menu more clear and compact... I think this is well for all people... And the work is only put some words in one file of sources. Well... sorry for my english Thx in Advance

Fwd: [Maybe OT] Linux Audio Apps Clasification

---------- Forwarded message ---------- From: Daniel Vidal <danielvidalchornet(a)gmail.com> Date: 2009/11/6 Subject: Re: [LAD] [Maybe OT] Linux Audio Apps Clasification To: Pedro Lopez-Cabanillas <pedro.lopez.cabanillas(a)gmail.com> Thx Pedro (¿i can say "gracias Pedro?) Yes... i read the standars before post. But my call is not only to make new categories but also to apply existing ones... a very large number of audio apps comes with only "AudioVideo" tag... And yes... This task can be done for other people than developers... in fact the Suse packagers do this task to manage menus... Debian make your own .desktop files and put your own submenu... but only take two posible tags... "sound" and "video". The problem remains unsolved. I can also edit the .desktop files to put my own categories... but i think this is not a practical solution... if the user update any app... these changes can be lost... and the user can view how the app disapear from the menus...

My proposal of categories are just a suggestion to initiate the discussion... About the number of categories... Not are a direct relation betwen number of categories and submenu groups... These categories are used by the people that design the menu to include (or exclude) apps in the menu groups... I can put together audio players with audio file managers... or not... i can put together secuencers with drum machines... or not... But i need these categories to do this work... I cant make a serious multimedia menu if all apps are only "AudioVideo" apps.

by Jörn Nettingsmeier

might be of interest to some LAD patrons: -------- Original Message -------- Subject: [Sursound] Call for Participation: Int. Symposium on Ambisonics and Spherical Acoustics, 2010 Date: Wed, 4 Nov 2009 12:57:25 +0100 From: Markus Noisternig <Markus.Noisternig(a)ircam.fr> Reply-To: Surround Sound discussion group <sursound(a)music.vt.edu> To: Surround Sound discussion group <sursound(a)music.vt.edu> [Apologies for possible multiple copies] ----------------------------------------------------------- 2nd Int. Symposium on Ambisonics and Spherical Acoustics May 6-7, Paris, France, 2010 ambi10 - First Call for Participation http://ambisonics10.ircam.fr Dear Colleagues, We would like to announce the 2nd International Symposium on Ambisonics and Spherical Acoustics, which will be organized by IRCAM, together with LIMSI-CNRS and France Telecom/Orange Labs. The Symposium will be held to provide an intensive exchange between industrial and academic researchers working in various research areas on spherical acoustics. The field of spatial sound reproduction is interdisciplinary by nature and closely related to a number of computer science and engineering areas such as acoustics, mathematics, signal processing, and perception. The symposium focuses on discussing the various problems and solutions concerning the capture, analysis, and re-synthesis of sound fields applying spherical acoustics; for example higher-order Ambisonics (HOA), and spherical microphone arrays. The symposium is going to be divided into oral presentations (keynotes and submissions), poster sessions, and two demonstration sessions (artistic and technical). This symposium will benefit from a hemi- spherical loudspeaker array that will be installed for the duration of the symposium, which will be held in the Espace de projection, the variable acoustics performance hall of Ircam. Original contributions are encouraged in, but not limited to, the following topics: * General considerations on spherical acoustics theory * Ambisonic for sound scene reproduction and virtual acoustic environments * Spherical microphone array systems and signal processing * Capture and analysis of radiation patterns * Spherical acoustic holography * Synthesis of directional and focused sound sources * Spherical loudspeaker array systems and signal processing * Theoretical considerations on comparative subjective and objective studies * Standardization, exchange, implementation and hardware issues Submission ========== Submissions will be judged based on extended abstracts (1000 words). Procedures to submit papers, posters, and demo sessions are detailed at the symposium website http://ambisonics10.ircam.fr. Final papers must be camera-ready conforming to the format specified on the submission website. Several excellent papers will be selected for collective submission to Acta Acustica united with Acustica. These papers will be expanded versions of the presented works, and will go through the standard peer review process. The official language of the symposium is English. Important dates =============== * Extended abstract (1000 words) submission due: January 8th, 2010 * Papers, Notification of acceptance due: February 19th, 2010 * Camera-ready copy (full paper): March 12, 2010 * Registration opens: March 22, 2010 * Late Registration: April 12, 2010 * Submission of Audio Material for Testing: April 19, 2010 * Symposium Dates: May 6-7, 2010 Symposium Chairs ================ General Co-Chairs Markus Noisternig (IRCAM - UMR CNRS) Brian FG Katz (LIMSI - CNRS) Rozenn Nicol (France Telecom - Orange Labs) Technical Program Co-Chairs Nicolas Misdariis (IRCAM - UMR CNRS) Olivier Warusfel (IRCAM) Administration Chair Sylvie Benoit (IRCAM) _______________________________________________ Sursound mailing list Sursound(a)music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
