Slashdot Mirror

"According to their FAQ and their official statement in the Czech Linux mailing list (both links are in Czech, sorry), they plan to GPL the StarOffice localization files after May 31, 2001. To make things even more interesting, they additionaly permit to use the StarOffice localization under Debian and Slackware after February 28, 2001. But when you use Red Hat, Mandrake, TurboLinux or anything else, you either have to switch your distribution, or wait until June.

Do not get me wrong, they can put any license they want on the software they developed. But I definitely do not think this is the right thing to do for an Open source(tm) company.

I should probably add a background info about Linux in the Czech republic: The most difficult part about Czech localization is, that we do not use ISO 8859-1, but ISO 8859-2. So we cannot use the standard PostScript fonts directly, we have problems with software, authors of which think everyone uses ISO 8859-1, etc. The most popular distribution here is definitely Red Hat Linux, but others (such as Debian, Slackware, Mandrake or SuSE are widely used, too). Only SuSE has the development team here, though. In the SuSE Czech (or with its funding) are developed for example the ALSA project, Linux Input drivers, etc. A majority of the Czech kernel developers work at least partly for SuSE (Martin Mares, the kernel PCI guru, Vojtech Pavlik, to name at least few).

So SuSE Czech definitely does some good things, but their StarOffice localization licensing is, to be honest, unfortunate. What do you think about this?

In the computer world's neverending list of confusing acronyms, OSS is used in a lot of different ways. I had the opportunity to speak with Dev Mazumdar, president of 4Front Technologies, the people behind OSS (hang on, you'll find out which one!) and xmms to clear up the confusion.

"OSS is Open Sound System and in this case, the word 'Open' implies 'Open Systems' which are typically UNIX (aka Solaris, AIX, BSD, UnixWare, etc.) based."

"We coined the term OSS before there was any concept of Open Source Software pitched by ESR. However, there is an 'Open Source' version of OSS known as OSS/Free which is distributed with the Linux kernel sources. OSS/Free (aka Voxware) is also distributed in the FreeBSD kernel. OSS is actually an API with both commercial and free software implementations -- much like X Windows, where there are XFree and commercial implementations from companies like XiG, MetroLink, etc. We are just the copyright holders for the OSS API (which is distributed under a BSD-like license)."

So, what's new in the world of the Open Sound System? Dev continues:

"The biggest news, of course, is support for more and more soundcards and the fact that companies like Creative and Aureal are doing their own drivers based on the OSS API. Additionally, there are more and more commercial companies developing apps on top of the OSS API, which means that these apps work perfectly on either OSS/Free, or our commercial OSS drivers -- and this translates to FreeBSD, Solaris, and UnixWare users being able to use Linux binaries on their operating systems via Linux emulation."

"In terms of other stuff that we do, XMMS just won the Slashdot Beanie award ... that's huge."

Dev's company, 4Front Technologies, has gotten a lot of flak on Slashdot and other places for thriving on proprietary software. Dev said he hopes that Linux and Open Source advocates can see the forest for the trees, and he explained what 4Front is doing with OSS.

"If you are talking about OSS as in Open Source Software, then basically, we've given up the control of OSS/Free to Alan Cox so that he can shepherd the continuous development and as a matter of fact, there's tons of good work going on in the Linux 2.4 side -- people have been fixing configuration and driver bugs so that Linux 2.4 is going to have some really good sound support."

"However, we do have an Open Source Software program -- X MultiMedia System (XMMS) that's GPL'ed, and that as you know has been winning rave reviews. 4Front's employees, Peter, Olle and Thomas are being paid to work on XMMS. While XMMS doesn't earn us any revenue, we do sell the QSound plugin for XMMS which gives us a little more revenue from XMMS."

"XMMS is proof that 4Front is not all about closed-source software ... we do closed-source software (aka our sound drivers) to make money, in order to do other open-source stuff and of course to make a living. The fact that XMMS won Slashdot's Beanie award says volumes about 4Front's 'products' and our engineering ability."

You really couldn't ask for a better flagship sound product than XMMS, but working with OSS still has it's challenges.

"Currently [the biggest challenge is] getting the SBLive, Maestro and Vortex drivers working with all the bells and whistles. While Creative's and Aureal's own OSS compatible drivers work much better than ours, they are only Linux oriented. We have SBLive and Vortex running on other operating systems like Solaris, FreeBSD etc."

"Some of the other challenges are getting OSS supported on BeOS or other operating systems. It's more the case of lack of manpower than the engineering skills to do it."

Dev feels that the key to getting great audio authoring tools working on Linux is to pull in the celebrity angle on the production end.

"Right now, there are some really good programs like Snd, Slab, Jazzware, Rosegarden, Broadcast2K and MP3 stuff. But what is needed is one good example of a popular musician to come out and say 'I made this multiplatinum album using Linux!' The 'Titanic made on Linux' was a tremendous boost for Linux, we just need a similar boost -- even if Linux plays a small part in the production who cares as long as someone like Madonna, or any of the teen idols say they used Linux. This will be a wakeup call to the applications industry to start paying attention to Linux."

"The future of music on Linux lies in application support it receives. Currently, we do have all the major apps like RealAudio, MP3, Flash, ViaVoice [and] Loki Games working, but some of the 'pro' audio stuff like ProTools, SoundForge, or Cakewalk are sorely missed on Linux. But we think that these apps will never see the light of day on Linux because the userbase is most happy with the Macintosh or Windows environment. I have many friends in Hollywood who are either scoring music for movies and music videos or are sound engineers, and all of them are wedded to their Macs -- you couldn't pry their cold dead hands off their Macs! We really need support for the pro audio hardware -- stuff that sound engineers use on their Macs. We'll probably get there some day, but until then, we in the Linux community have to bite the reality pill and accept that Linux is not there yet."

"There is another side to music production and that's the realaudio or icecast/shoutcast MP3 stuff. This is where you'll see more Linux/Unix machines. We're working with a couple of radio stations to implement Real Audio live streaming servers using Linux."

When it comes to breaking into the semi-professional and professional audio production space, the ALSA team is making some strides. I spoke with Jaroslav Kysela, SuSE developer and head of the ALSA project. First, I asked Jaroslav about what ALSA was, and how it differed from the OSS efforts.

"The ALSA abbreviation means the Advanced Linux Sound Architecture. We offer a modern sound driver and basic audio library for this driver. Along these main goals, we are working on configuration tools for end users to simplify the installation and usage."

"We want to give the real audio power to the Linux users, because interfaces, used in Open Sound System, seem to be very limited to us. But compatibility is a major key for us, too. We provide the complete OSS emulation implemented in add-on layers."

"We definitely entered into world of semi-professional and professional audio. Actually, the ALSA driver package contains code for RME Hammerfall, RME Digi 96 and Envy24 (MidiMan Delta series) soundcards."

"Other hot news is that the ALSA driver can forward the AC3 stream through the S/PDIF output. Linux DVD players may use this feature."

"Also, we have positive signals that the ALSA driver is going to be merged into Linux 2.5 development kernels. That is a preliminary fact, but we hope that our dealing with Alan Cox will be successful."

SuSE is well-known for a solid Linux distribution as well as video card support out the wazoo. What's SuSE doing with ALSA?

"I have to do some advertisement here ;-) SuSE is very helpful, because the ALSA professional team works full-time on the ALSA project. The team has two members and we will grow to three members soon."

"More information about the ALSA professional team may be found at http://www.alsa-project.org/announce.html."

"The primary goal is the integration into the Linux 2.5 development kernel. Also, the development continues. Some things are still waiting for the implementation. I may notice support for four and six speakers to create a interface for 3D audio layers and software DVD audio decoders. We want to finish the documentation for application developers and the work on the driver configuration utility is in progress."

What about music production on Linux, Jaroslav?

"This is a bit difficult question, because I am not a musician and I spend most of my time only with the driver development. I personally think that the current progress in this area is very promising. For example, Jazz++ sequencer is covered with GPL now. The support for professional cards in ALSA provoked next reactions like Ardour (a multitrack recording application). I feel, the actual situation with Linux music and audio applications will be better and better."

Well, the worlds (and acronyms) of OSS and ALSA are no longer a mystery. Moving steadily from technology to the artist, we turn to the universe of notation. While it may have been good enough for the Beatles not to be able to read sheet music, the rest of us may need a staff and notes to know how to play 'Please Please Me.'

Well-known Linux music packages Brahms and Rosegarden handle notation, as do lesser-known programs like Lilypond, which can convert your source file to a TeX file, or Mup, which will convert your music to a postscript file that can be printed as standard sheet music.

For a super-techy way of handling notation under Linux, check out Haskore. From the Haskore web documentation: "Haskore is a collection of Haskell modules designed for expressing musical structures in the high-level, declarative style of functional programming. In Haskore, musical objects consist of primitive notions such as notes and rests, operations to transform musical objects such as transpose and tempo-scaling, and operations to combine musical objects to form more complex ones, such as concurrent and sequential composition. From these simple roots, much richer musical ideas can easily be developed." An example of Haskore expressions, check out http://haskell.org/haskore/onlinetutorial/childsong6.html.

I hope you've enjoyed reading this series as much as I have writing it. From professional music production to hobbyists, from track editors to free content licenses, from acronyms to notation, we've run the gamut.
