Hi folks, we are currently developing a game using fmodEx as soundlibrary. Now we are searching for a way to give ladspa (or dssi?) plugin-support to fmod (for linux, win & mac). Fmod itself: "New file formats, output modes, and encoders may be added or downloaded by the user as DLLs. VST and Winamp DSP plug-in support for effects is included." Does anyone has any experience with that topic? Greetings, Nils Cologne

[LAD] [ANN] pyjackctl 1.0 released

by Marc-Olivier Barre

Hi, Pyjackctl 1.0 is out. let's just call that the "lac2008" release :-) This project was created to take advantage of Nedko Arnaudov's JACK Audio Connection Kit (improvements) patches, especially the dbus proof of concept patch. It offers basic functionalities to control a JACK daemon over a dbus interface (start/stop, configure, etc.), it also includes a jack log viewer, a wmdock applet and a script to display jack's state on a G15 keyboard's LCD. Those curious of how it looks will find a set of screenshots on the homepage. You are welcome to test and comment. homepage : http://www.marcochapeau.org/software/pyjackctl download : http://www.marcochapeau.org/files/pyjackctl-1.0.tar.gz The necessary set of jack patches can be found here : http://sharesource.org/project/jack/ Please keep in mind that this is a proof of concept to explore new ideas, not a finished product. __________________ Marc-Olivier Barre, MarcO'Chapeau.

[LAD] Audio game, Be The Wumpus

by Stephen Cameron

Here's a little audio game I made which you guys might try when you want to take a break for your Serious Audio Work. http://bethewumpus.sourceforge.net In this game, you're a wumpus, living in a cave, and you eat the wumpus hunters who fall into your lair, locating them by the sounds they make, of course. It does require a usb gamepad, like a Logitech Dual Action gamepad, or similar. (Haven't got the rumble function working on it though, I think nobody knows how yet.) If it weren't for this list, this game wouldn't exist. -- steve ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!

[LAD] FreeDots: MusicXML to Braille music notation

by Mario Lang

Hi. This is a very early announcement of a piece of software I am working on which is currently sort of in its prototyping stage. I recently played with optical music recognition, a pretty interesting topic to a blind musician. The OMR software available today is getting better, and some sheets I scanned actually produced pretty usable results. However, only listening to MIDI files is not very usable for learning music to me (all the on-screen score display programs I know of are totally inaccessible to a blind user). So I needed a way to represent the scanned data in a usable way to a blind person. Braille music is an established standard, and actually pretty nice once you managed to learn enough of it for it to be useful. There is a commercial product around to transform NIFF files to braille music, which costs 3 times as much as the actual OMR software. This sillyness inspired me to write something myself. Since NIFF is effectively dead, and all major OMR programs these days do export to MusicXML as well, I decided to use MusicXML as the base input format for my project. Its also lots easier to develop than NIFF based software since the file format is actually human-readable, not a binary format and very easy to parse (XML). That said, braille music is a very complex standard. FreeDots as of now does only implement the very rudimentary basics, i.e. notes and rests, interval symbols and some basic form of repetition detection. That said, it has already been useful to myself as a tool to study music scores for memorisation. FreeDots can already play back the score (via MIDI) and also provides an interactive mode for braille display users which allows you to "click" (using the so-called cursor routing keys) on an individual braille music symbol and have it played back to you. This is extremely useful (at least to me) while learning to read braille music. If you aren't quite sure what is written in a measure, just invoke the symbol you are unsure about, and it will be played back. I know that probably most people on this list do not have any use for this software, but I also know that we have at least one other blind user here. Since FreeDots is being developed on Linux (I actually plan to port it to Windows as well so that blind users can use it as an alternative to the unnamed, high-priced commercial software available to do the same thing), I could not resist to announce it here :-) FreeDots is written in Python, using the lxml library for XML processing and the pygame library for playing back MIDI output. The design should make it relatively easy to add more input formats. For instance, a Humdrum parser is one thing I'd like to have at some point. MIDI should also be possible as an input format, but that would require a bit of pseudo-AI for good results. http://delysid.org/freedots.html Why not use Lilypond? There are several reasons why I did not use Lilypond for this project: 1. OMR programs do export to MusicXML, not .ly I want a simple way to scan a sheet of music and be able to read it myself. Since MusicXML is what the good OMR engines support, this format was chosen as a starting point. 2. MusicXML has a nice and clear distinction between the graphical representation of musical events, and the sound representation. This makes it much easier to write code for braille music translation if you are yourself blind, and can not look at the score you are working with. 3. The Lilypond source code is unreadable to me. I've played with the idea of adding a braille music export feature to lilypond since years, but whenever I tried understanding enough of lilyponds codebase to actually try to attempt such a thing, I failed completely. The destinction between different output format rendering in lilypond is not at all clear to me. I just dont understand how to add a new output format. If anyone on this list is knowledgeable enough to start such a project off, I'd be more than willing to help to get the implementation of the actual braille music formatting rules done, but I just can't get the initial work required to add a new format to lilypond done. -- CYa, ⡍⠁⠗⠊⠕ | Debian Developer <URL:http://debian.org/> .''`. | Get my public key via finger mlang(a)db.debian.org : :' : | 1024D/7FC1A0854909BCCDBE6C102DDFFC022A6B113E44 `. `' `- <URL:http://delysid.org/> <URL:http://www.staff.tugraz.at/mlang/>

[LAD] LAC 2008: live online Now!

by Eric Dantan Rzewnicki

The 6th annual Linux Audio Conference has begun in Cologne, Germany. It runs today through March 2nd, 2008. As with each previous year this year's conference is streamed live over the internet in ogg theora via icecast. The stream status page can be found at: http://lac.linuxaudio.org This year we are in the unique situation of having a Gigabit link donated by CITIZENMEDIA: http://www.ist-citizenmedia.org/ They have asked us to use up as much of their bandwidth as we can so they can see how well the link performs. Please forward this information widely so we can help them out. This year the core team, Joern Nettingsmeier and myself, are recruiting volunteers to spread the workload. To that end we have set up a mailing list and irc channel to coordinate our efforts. If you are here in Cologne for the conference please consider joining us. If you are not coming, please enjoy the fruits of our labors by watching the streams and participating via irc. stream team mailing list: http://zhevny.com/mailman/listinfo/lac-streams general conference chat: #lac2008 on irc.freenode.net stream team tech talk: #lac2008-tech on irc.freenode.net Thanks, LAC streamteam -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[LAD] BCEdit 2000 for jre1.6

by Jens M Andreasen

Hi! I got meself a new java runtime (1.6) which has support for ALSA midi, so I thought that I would give Behringers BCEdit another go. This time around it actually finds the BCR2000, but ... unfortunately it couldn't save any edits back to the device. So I disassembled the application :-D The main reason for disaster appears to be in bcedit/ThreadSendScript.java where too much verbose error checking for timeout causes the very timeout it is checking for and then also - for no apparent good reason at all - closes the midi device underneath the application, leading straight into a burn and crash. I have an updated bcedit.jar here, so if anybody is interrested in trying it out or placing it somewhere on the web, just give me a call. Decompiled sources are available on request as well (beware though, not everything builds just yet.) License: Free as in Behringer ;) -- mvh // Jens M Andreasen

[LAD] ingen & slv2 build on amd64 workaround (Gentoo ebuild)

by audio-mobster

The build didn't work for me at first. Don't know if stuff works, but it compiles! Workaround, if slv2 doesn't compile set-fPIC: CFLAGS="-march=nocona -O2 -pipe -fomit-frame-pointer -fPIC" \ CXXFLAGS="${CFLAGS}" emerge -uDvNa slv2 then: ln -s /usr/lib64/pkgconfig/slv2.pc /usr/lib64/pkgconfig/libslv2.pc emerge ingen stop emerge ingen after src unpack ln -s /usr/lib64 \ /var/tmp/portage/media-sound/ingen-9999/work/ingen-9999/lv2/lv2/osc/.libs ln -s /usr/lib64 \ /var/tmp/portage/media-sound/ingen-9999/work/ingen-9999/redlandmm/src/.libs restart emerge Hopefully complete.
