On the same day that Mozilla 1.0 was released last week, we released version 1.0.0 of Audacity, our GPL cross-platform audio editor that has been under development for nearly three years. It is based on wxWindows and runs natively on Linux (of course!), Windows, Mac OS (both 9 and X), and some other POSIX systems. Version 1.0.0 just adds a couple of minor features and bug fixes, but it is basically stable and quite useful, though it has some limitations. In addition, we also released a snapshot of our unstable development branch as Audacity 1.1.0. This version adds support for 24-bit and 32-bit samples, automatic resampling, LADSPA plug-ins, and internationalization, plus it has many nifty new UI enhancements."

    Euw. A package management system, like any other management system, has network effects. I.e, the power of the system is the square of the nodes. I don't install unpackaged applications because removing one of those nodes has a substantial effect on the usefulness of the system. I.e, I can't install any apps on top of Cinererella if I install it from an unpackaged tarball. Luckily we have the Linux Standard Base and RPM, but the
    Cinererella package apparently must be force installed. Euw.

    If Heroine Warrior or anyone reading this will host it, I can provide RPMs that will install on most major Linux distributions. If package dependencies are a support issue that HW don't want to deal with, make an apt repository to serve out the RPMs. Any dependent package will be downloaded as necessary from the apt source of the main distro and installed automatically.

      Reminds me of Broadcast 2000 (from the same authors). When I once downloaded the source, and started looking at it, the source tree contained about 10 general-purpose libraries (maybe some of them modified?), and I recall very soon finding a note somewhere basically saying "Do not try to compile this yourself! If the binaries work at all, use them! This will probably not compile!"

      Now looking at the source of cinerella, I see directories such as:
      cinelerra-beta1/audiofile
      cinelerra-beta1/freetyp e-2.0.4
      cinelerra-beta1/libavc
      cinelerra-beta1/l ibsndfile

      cinelerra-beta1/qu icktime/ffmpeg-2.4.5
      cinelerra-beta1/quicktime/la me-3.92


      Maybe the HW people can roll up some spiffy software, they sure don't know how to do it the clean, unix-like way! It was quite a surprise to download the huge Broadcast 2000 package over a modem line, only to discover it contained half a dozen libraries I already had installed. So be careful of what you promise.

      (Not to mention their over-arrogant way of expressing things. Somebody already commented on their page, and as I understand from cinelerra-beta1/make_packages, the package info is along the lines of:

          That's funny. I've been saying this about Linux for the past few years. The problem you describe is entirely true, but it is much more severe. This isn't just a problem with Multimedia in Linux, this is a problem with binary compatability between distros.

          The only way to ensure you get the libraries you need is to package them with your application. But, RPM is only good at packaging one thing at a time. One application, or one general library. If you try to cram both into a single RPM, you'll get funny problems when you try to install it.

          For instance, I can see why they suggest rpm -i --nodeps --force package.rpm. If one of the libraries is already installed, RPM will refuse to install the entire package because it doesn't want to overwrite a file. Obviously their solution could have been better implemented (put the libs in a subdir that won't break things and L_PRELOAD them from there), but the problem really shouldn't have been an issue in the first place!

          But it is, and it is because Linux has no standards. Anyone can roll their own Linux system, but that potentially breaks everything that a software vendor could ever expect to find on that system.

          The fact is, we need to get a standard to cover what a Linux distro must have to be considered a usable system. The LSB has about zero steam on its own. Its best shot is UnitedLinux, but of course everyone wants to instantly condemn UL because of what they thought they heard someone think they believed last tuesday under a full moon.

          All I can say is, I hope UL make it through long enough to at least establish some consistency between the involved distros, and that people notice how useful that really is before it is too late... I'm not the only one who sees this.
          • I don't think the "library hell" we have imposed on ourselves is so much a function of limitations in RPM, but rather inconsistent packaging. You can do anything with an RPM if you know how to tweak it. The problem in my mind comes from inconsistent library naming.

            For example, say you have libfoo which you package as Version: 1.0. When you move to libfoo v2.0, you introduce feature changes that make it incompatable with v1.0. Theoretically, you could have libfoo.so.1.0 and libfoo.so.2.0 installed at the same time, but you kept your RPM named libfoo for both RPMS. Thus, the RPM engine won't let you have both installed at once. If the new library had simply been named "libfoo2", no problem.

            All this gets back to what you called for: standards. While I don't think UL is the best way of doing it (they are only interested in dethroning RedHat), LSB would be a good place to start.

            As for multimedia applications, they have a different sort of library hell. Most of these libraries are 0.x betas and thus their feature sets are evolving by the day. To release your application, you generally have to include the libraries from a given day just to lockdown what features your application will use. Once these libraries and applications mature, maybe things won't be so bad?
          • Unfortunately, we have a little thing called "competition," and when two or more businesses have a bottom line, on the line, then you get inconsistencies. They may all state that they support LSB, and they all probably do. But then every distro will add their features which make them different from every other distro and then you have the same problem over again! Developers will become dependent upon distro-specific features and the LSB will fall very very behind. One person claimed that the LSB would simply be updated. I say this is horseshit. You can't have a moving standard because then it is no standard at all! There would become many many LSB versions in a short time and you would have LSB-version incompatibilities.

            In the end, it will be Red Hat that sets the standards for Linux. Infact, they already do with RPM. Even Slackware comes with RPM integration (strong *ix philosophy meets desktop user-friendly philosophy).

            There are problems with LSB itself. It has to define way too much to be useful (which it can't and doesn't) and LSB-compliant applications are way too restricted to be useful. GNOME/KDE applications are not LSB-compliant, for example. And never will because then LSB would require all implmentations to have KDE/GNOME installed (and would have to define the precise version of every library which consists of a "GNOME system" and a "KDE system".. a near impossible task at that).

            The LSB is a pseudo-standard. It defines many interfaces, but it leaves it wide open for interpretation. For example [linuxbase.org] (context: LSB application compliance):
            5. It does not use any interface or data format that is not required to be provided by a conforming implementation, unless:


            [...]

            * The use of that interface or data format, as well as its source, is identified in the documentation of the application.
            As you can see, this is pointless standardization and, IMO, will never get anywhere. The problem with defining Linux is that Linux can be anything to anyone and programmers tend to not conform to standards unless there is a _technical_ barrier that conforming to the standard is the only way to get around that barrier. For example, not too many people conform to UI guidelines, but everyone who wishes to use an internet RFC follows it precisely.
    • Unfortunately apt-get and RPM don't solve much either.
      I've tried today to get my system to use this, but I can not find many RPMS that I need. It basically means that I must use those that are provided which are often old versions or they link against optional things that I don't want. Still can't find an xvid RPM what avifile links against for example.
      Still, using the source is the best way and the little problem I have to maintain my own list of dependencies isn't that hard to do.
      • I've tried today to get my system to use this, but I can not find many RPMS that I need.

        Freshrpms contains all of Red Hat 7.3 plus a wide variety of additional packages. It doesn't include avifile (but rather, mplayer and xine) but Mathhias Saou, the maintainer, will generally provide additional packages on request.

        Alternatively, you could set up your own local apt repository. All you need is a http server (apt-get install thttpd), some packages, and the genbasedir command, which creates some indexes.

        The source is the best way, but unpackaged source isn't. It takes less than five minutes to create an RPM from any app that uses GNU autoconf once you're familiar with the system, and if you have the brains to compile your own software, you have the brains to create packages. I'd suggest taking a look at the IBM Developerworks RPM tutorial sometime.

      • >If they can afford to pay for a computer, digital cameras, and a cast, I think it's safe to say most of them can afford something much nicer, like Final Cut Pro.

        I would say not. Final cut pro costs $1000 [macworld.com]. A decent Mac costs $3000 [apple.com]. Pi (an independent filmt that actually "made it") had a budget of $60,000 [imdb.com]. If 7% of that budget was on computers, I doubt the film would ever be made!
        • You could easily run Final Cut Pro on an iMac, or even an eMac. I've run it on a 450Mhz G4, it should work fine on anything faster - such as a used Power Mac, or possibly even a G3 iMac with a memory upgrade. That means the entire computer+software budget is a one-time-only $2000-$3000.

          Besides, Final Cut Pro is definately worth the money if you're doing anything serious. Or, if you don't want to buy a Mac, you could use Adobe Premiere or another such program. As promising as Cinelera might be, I seriously doubt it will ready for production use anytime soon.

    The cross-platform compatibility is done with Qt, so the basic user-interface quality is very good. Some strangeness in some video editing UI concepts, but otherwise excellent.

    • I've tried the Linux demo version abt two years ago. It was rather nice even then.

      I've used MainActor (I paid the $99 license fee), and it will turn your GNU/Linux box into a Microsoft Windows box ... the program is very unstable, and the one rule of thumb was 'save early, save often' (and you still will probably lose some of your work).

      Worse, GNU/Linux bugs seemed to get fixed last ... support was much better for Windows users than GNU/Linux users.

      I have since switched to using kino for my NLE needs (which are quite simple: cut, rearrange, export into a form transcode can manipulate), and while it isn't perfect, it is a heck of a lot better than MainActor. I don't need fancy star wipes (hey Homer) or text overlays ... I just need to be able to snip commercials out of my Max Headroom recordings, to edit out the dead space in my home videos, and rearrange some of the takes in my home movies. For that, kino is sufficient.

      I do hope Cinelerra is good, works, and actually remains supported by the authors for a time, but as another noted, the authors do seem pretty 'flighty', particularly in the context of the bizarr removal of Broadcast/2000 off the web a while back. One hopes it is, as another noted, just a quirky sense of humor on the authors' part and not a sign of deeper waffling on the whole software freedom thing, as even a buggy (and discontinued) GPLed product can at least be improved upon ... something I waited quite a while in vain for with Main Actor.

During capture, it went into an infinite loop, and quickly filled up my entire HD with a bogus video file. Oh yeah, and installing it suid root was great- it overrided system files. Not even an fsck could save my poor box. I'll stick with trying to learn Cinelerra and Jahshaka, thank you very much.

      The GUI is written in QT so it is quite possible that he is just using a very dark unflattering theme.

      They could probably benefit from a more convential interface and include Menus and keyboard shortcuts (i cannot see any from the screenshots).

      iFrames on the website cramped layout, no Menus in the program. Definately a project that would benefit from a some usuabilty analyis.

        • i can see the resemblance but the problem is the mac does have a toolbar and menus (just not in the main window)

          and "once you get the hang of it" does not mean it is even easy to use or remotely likely to meet the reasonable expectations of an ordinary desktop user.

      Hi, I'm one of the Audacity developers. A few of us are following the discussion here, so feel free to ask questions of us.

      Regarding the MP3 exporting, the next Audacity 1.1 release can export to arbitrary command-line programs on Linux. The code in 1.1.0 has some bugs (doesn't work on big-endian hardware) and no user-interface yet, but see this mailing list post [geocrawler.com] for more information.

Dominic is planning a "Smart Record" mode where the program will do nothing but record samples with the minimum possible latency. On Linux, we also hope to move to ALSA eventually, which should help with latency.

    For working on audio samples, Audacity is GREAT. I had some old records that are not available on CD that I wished to preserve. The problem is that I've had these since the early 1970's and they are scratched and worn. I sampled them in, fired up Audacity, and used Audacity's noise filter. One of these days I'm going to look over the code for it - it must be some pretty tricky signal processing....

    You mark a section of noise, and tell the filter "See that: that's noise. Kill!". The filter will then remove that noise from the signal. The first sample I had the noise went from a "Schoosshh Schooshh" ever rotation to a very faint, high frequency "twinkle". Since the record was speech, I was able to then brick-wall filter that off, and Voila! I had an MP3 that was a pleasure to listen to, rather than a nasty scratchy mess.

    Audacity works. Well. Get it. Use it.

    (now, if only I could us it to filter out all the crap on the radio... But then I don't listen to the radio....)
    • >The problem is that I've had these since the early 1970's and they are scratched and worn.

      Well, now I'm confused. I've seen slashdotters tell me all vinyl beats CDs, and now you're basically saying it sucks?

      Can I use your comment next time I'm trying to explain to a vinyl always beats CD pusher that they're wrong? :-)
      • A coworker of mine has a good saying that is applicable when dealing with audiophiles like that:

        I don't argue with wheelbarrows, I push them.


        You may use my comments, for what little good it will do.
      • Scratched and worn vinyl sounds worse than CD audio.

        Vinyl only sounds better than CD audio if (1) the vinyl is in pristine condition and (2) it is played on some very expensive kit. Being analog, the sound quality of vinyl is only limited in theory by the quality of the gear used to record and playback. In practice, most equipment used to record and playback the vinyl medium has worse sound than CD audio.

        Of course, YMMV.

        • Vinyl only sounds better than CD audio

          It also sounds significantly better than a nonexistant CD. That's the case with 99% of my album collection. Stuff that will never be released on CD, like all of Tim Curry's albums, Little Nell's singles, etc. I listen to them on CDs and MP3s, yes, but those are captures from vinyl, either my own or a collector. One of these days (read: been planning it forever, probably never do it) I'm going to find a recording studio, pay a few hundred bucks for time, and play my virgin albums with a top of the line needle on a really good player, and do a serious high quality transfer.

          Vinyl is still important for quite a few things of historic and cult value. For that matter, so are casettes. I have the master casettes for quite a few interesting interviews and live performances that I'd like to get into a more portable media.

          • One would think (and I could be wrong on this) that the noise filters on software like Audacity and Cool Edit Pro could clean up the sound well enough that any moderately good ATDC would produce digital music that sounds at least as good (if not better) than the analog original played on regular stereo equipment. This should especially be true for your interviews and recordings of live performances unless you had some seriously good recording gear. The distortion introduced by conversion to digital should be well below the improvements that can be made by filtering out noise.

            The noise filter on Audacity is simply amazing. And Audacity is free!

            • This should especially be true for your interviews and recordings of live performances

              Yes, true for them, but not for the records. The interviews et. al I wouldn't do in a studio - a simple phono-phono plug to a sound card would be perfectly acceptable, as the source itself is low quality (as you point out). I've been slowly collecting MP3s via opennap and gnutella of all my casette only filk albums, and it's just easier to have a search for "Bayfilk" running rather than hooking up a casette player to my computer, and spend the time slicing and dicing the songs out myself. :)

      • Try some CDs you've got now after 30 years of use and then tell me that vinyl sucks. Goddamn I've got CDs less than a year old that don't play properly (and yes, I do look after them... well mainly).
        • I've got 15 year old CDs, and I copied them to CDRs to ensure they're preserved perfectly the other year. A couple of scratches made it a little difficult, but it could have been worse (I could have not recorvered the CDs at all)...

          Try doing that with vinyl ;-)
      • I'm not really a "vinyl beats CD pusher" or an "audiophile" but I do appreciate vinyl. I just bought 15 records today for a $1 a piece, most of which were classic albums (some of which I already owned on CD). I don't have great equipment (my cartridge costed $100 new), but even so, in most cases I like listening to the record better than the CD. If you actually sit down and actively listen you can't deny it. If anything, the sound is just different in a way that is pleasant and offers something that CD doesn't. When you record vinyl to CD quality you lose that something, I've experienced that myself.

        Though I won't say it beats CD, or vice versa. You've gotta take care of your records, putting them on is a bit of trouble, a flaky pitch control can be annoying, and you can't listen in your car or while you're on the go. I often rip my CDs (as WAV's) and queue up playlists, a convenience you generally don't have with vinyl.

        Digital audio is the way to go these days, but vinyl is still good. Though, maybe one of these 24-bit higher sampling rate formats will obsolete vinyl (I personally haven't experienced much of them so I can't say).
    • From looking at the site, it looks like audacity is mainly a stereo soundfile editor... does it do multitrack mixing a la Pro Tools? Or is there something else that does?
      • Dude, If you find the "multitrack audio recording and editor" for Linux that will do recording studio processes for Linux, please let me know as well.

    Another poster pointed out that the source tarball contains the libraries of some 10 other OS projects. These include things like lame and libogg. Their previous product bcast2000 used it's own (ugly) widget set as well. We're probably fortunate that this NLE works as well as it does and is polished as it is.

    It's hard for me to fathom just where these guys are coming from. Their methodology seems to suggest that they are talented Windows developers who don't even remotely get how UNIX works. They spring this NLE on us almost fully grown and then abruptly pull it because of some shadowy "liability" concern. They then spring its successor on us and are threatening to take it to Windows. There is also an announcement of an upcoming beta on their page where they point out that "it is STILL a native Linux program and won'
    t take advantage of "win32 features".

    I won't be in the least optimistic about this project's long term Linux prospects until I see a credible UNIX focused fork. These guys are good and wrote some nice software in spite of themselves but as far as their UNIX support goes they're flighty.
    • I think the HeroineWarrior coders simply enjoy pulling people's chain. Its very obvious to me that they're pure-bred *NIX people with an over-active sarcasm-center.
      If you go through the site you'll find all sorts of odd statements, and ultimately, I think the whole "pulled because of liability concerns" thing was just another manifestation of their odd sense of humor, as is the "moving to win32" thing.
    • A couple of points:

      1. I'm under the impression that "these guys" is actually "this guy". Incredible as it sounds, I think this entire app is the work of one brilliant and somewhat eccentric developer, Adam Williams.

      2. I don't think he's a Windows developer at all; in the documentation that comes with Cinelerra, he provide an explanation of why he chose to use symlinks rather than use the usual libraries.
  • I've used Broadcast 2000 and found it servicable for some things, but not as stable as I'd like.

    I'm still searching for the multi-track recording software of my dreams (ardour sure looks nice -- if only I could make sound come out!)

    No matter -- this is pretty exciting to me, even if I am little more than an end user and not the sophisticated sort the authors are aiming at.

    About cinelerra: As I understand it, the author of broadcast 2000 (which is the same as cinelerra) had an agreement with a company that packaged broadcast 2000 and sold it with support. At some point it appears someone threathened to sue the author, and he withdrew the project.

    You can still find the sources to broadcast 2000 on the internet (I even think it is part of the cinelerra sources) and there is also a patch floating around that adds ogg vorbis and openDivx support to it.

    Its about a month since I last checked out Cinelerra. At that point it was rather complicated to build - the makefile has errors that will allow the build process to fail but will make it appear to the user that it went OK. When built, it does work, but it is limited in its supports of Video encodings, which is a shame. The DV import module crashed for me, which means that I would have to convert all my DV streams to MPEG2 or MOV format, which is not so great. If you wish, however, the mjpegtools can be used for this.

    Cinelerra has a number of transitions etc, which is great. However, a month ago, there were many glitches, and in general the program did not seem stable.

    Several people mentioned MainActor. This program works well (for me) and the demo edition will work for as long as you wish, although it will print "MainActor" on any frame rendered by the program. (Read: If you do not manipulate the individual frames, you can actually edit all that you want, but transitions will have the stamp and so on). It does cost money though, and is not OSS. MainActor also have support for text effects, titles and so on. (Which I have not seen on any other Video editor for Linux).

    If you are taking up video editing on Linux and you have a DV camera, you should definitively check out Kino. (at sourceforge). Disclaimer: I recently got cvs write access to kino. Kino is build for DV editing, and will keep the DV metainformation, etc, while editing. It has a nice interface - both menus, toolbars and vi style keyboard shotcuts. But, there are currently no support for transitions, titles, or anything like that. Kino cvs, which currently depends on libdv cvs, contains a module called "dvscript" that can be used to create some simple transitions, as well as streams from pngs, etc. I believe it is the plan to eventually integrate this functionality into kino proper.

    If you are taking up editing, but mostly with analog video, you shold consider buying an analog to DV converter (An external box that works with Linux costs about $199 + a firewire card). In any case you also want the mjpegtools (sourceforge) to be able to work with captured streams, remove noise, constructs streams that can be used for videoDC's etc. Mjpegtools also support some hardware accelerated capture cards and jpeg compressors.

    Kino can export a playlist to a format the mjpegtools can read, which means that it is easy to create e.g. mpeg2 or DivX streams from your DV input.

  • Ok, so let me get this straight... the initial program that was put out was Broadcast 2000.
    However, the program was capable of doing "Professional" quality and features, but there was the chance that it had a few major bugs.
    Soo.... the company pulled the product in case some major company sued them for lost information when the program crashed. This just doesn't seem to make much sense.

    Question: Can I sue Abobe/Macromedia/Digidesign/Avid/(Insert company here), when Photoshop/Flash/Protools/etc... crashes and I lose a client's information? Because that's what they seem to be afraid of. Instead, couldn't have they just called it a Beta or put a disclaimer on the page (or in the EULA?...)

    Don't tell me that each of you haven't lost information ever (well if you had a Beowulf cluster of redundant machines perhaps you haven't), to a program crash?
    Why could people sue about it in the first place? Java even has this little neat disclaimer....

    The Software may contain support for programs written in Java. Java technology is not fault tolerant and is not designed, manufactured, or intended for use or resale as online control equipment in hazardous environments requiring fail-safe performance, such as in the operation of nuclear facilities, aircraft navigation or communication systems, air traffic control, direct life support machines or weapons systems, in which the failure of Java technology could lead directly to death, personal injury, or severe physical or environmental damage.

    Which to me, tends to make me think that a simalar software disclaimer could put saying "If you are producing Starwars III on this, it probably won't handle the 1.7TB of information that the movie has..."

    Thoughts anyone?

      Hmmm, If Bcast2000 was distributed under the GPL, then there's a "No Warranty" clause already a part of the licence, which says that the developer is not responsble for any damages, losses, etc. you incur as a result of using the software. Of course, that's assuming it was distributed under the GPL...

    Now if only I could get xawtv to recognize that I have libquicktime.so on my machine so that I could save my video to .mov's (so that I can get more than 2GB at a time) I'd be set...

    Well, that and support for .ogg [XVid/VP3]/Vorbis video file encoding (MPlayer already supports playback at least, or so I'm told, and it sounds like support for this in ffmpeg [sourceforge.net] may be coming Real Soon Now from what I've seen on the mailing list...)

  • For a long time, we didn't have a Really Good audio editor to use in our magazine (and put on our cover CD) when writing about sound editing and conversion. The rest are either complex crippleware (GoldWave, CoolEdit), or too bad to be considered. Audacity fits the entry-level bill nicely with a few Very Obvious buttons right up front, and when you dig in, has lots of good stuff underneath.

I'd rather not use a app that is also built for Windows as I fear it's linux integrety is compromised. Also eventually I am interested in SACD production. Does Audacity support 24/96 x 6 channels and 24/192 x 2 channels natively. Is there a linux app that can write to DSD? Thanx, Bearcat
    • Don't fear, audacity is a gtk app as well. It is written to the wxWindows api, which is a cross-platform 'wrapper' that will allow you to compile to native applications on gtk, windows, or mac. Glame seems to me to be more concerned with creating effect networks for real-time processing, whereas audacity is more about recording, editing, and playing sound files. Furthermore, the linux version of audacity is probably the most stable, because almost all of the developers are using linux. It accomodates an unlimited number of channels, and the "unstable" branch release has the ability to use high-quality 32-bit float audio. But don't take my word for it, the download is small--try it out. You can even use both of them on your system, and neither will get jealous.
