[linux-audio-user] Looking for an external sound card for 'nix -- recommendations?

by Louis Acresti

(Forgive me if this is a duplicate, but it looks like the mailer dropped this message the first time..) I've been lurking on LAU for a few months now and I've finally managed to come up with something worth asking: I'm looking for an affordable external sound card for music production. What are your recommendations? Being a novice, I'm having trouble finding what I "need" (and I'm growing wary of google's pagerank system...) so I thought I'd query the real experts. ;-) I try to keep my options open, but there are some things I prefer: -It should be a hell of a lot better than the crappy onboard AC'97 sound I use right now (SNAP-CRACKLE-POP) -It should be external: USB or Firewire or otherwise are all OK (I'll be using it with my desktop now, but I plan on setting up a laptop for music some time) -It should be affordable: I can always make exceptions here (especially since I'm not very familiar with this type of hardware), but I'd prefer if it were around $200 USD or less. -It should be *exceptionally* functional with Linux and JACK. (Naturally, this is best proven through experience) -Although the above should cover this, it ought to work with my Novation X-Station synthesizer (which already works great through USB with JACK) I'd really appreciate any recommendations -- or blacklists (although ALSA's soundcard matrix usually faithful enough) -- of hardware to be used by a novice electronic musician. I try to be brief, so if I'm being too ambiguous just ask me for details! Thanks, -Lou

[linux-audio-user] sticky VU-meter for ALSA

by Florin Andrei

I'm looking for a stereo VU-meter that has the following characteristics: 1. can monitor any arbitrary (configurable) ALSA output 2. is "sticky", so it stays displayed when I switch between virtual desktops in my Gnome environment I guess #2 means it's either a Gnome applet, or some kind of OSD-based thing (with the aspect of the "LEDs" configurable in terms of size and coordinates). Suggestions please? -- Florin Andrei http://florin.myip.org/

[linux-audio-user] [ANN] Mammut V0.59

by Kjetil Svalastog Matheussen

*About: Mammut will FFT your sound in one single gigantic analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms prior to resynthesis. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. *Homepage: http://www.notam02.no/arkiv/doc/mammut/ *Screenshot: http://www.notam02.no/arkiv/doc/mammut/mammut.png Changes 0.57 -> 0.59 --------------------- -Added workaround for rare sound corruption bug. -Added the "Redo it!" buttons. (The same as pressing "Undo" + "Do it!") -If playing while pressing a "Do it!" or "Redo it!" button, continue playing after processing as well. -Added the "Random Phases" toggle button in the "Multiply Phase" dialog. Checking this button will freeze the sound. Thanks to Tim Blechman for the idea. -Fixed looping which wasn't turned off if using a different sampling rate. -Added "make install" and "make uninstall" -Fixed animation bug. (should allways be shown now) -Fixed a couple of more int->uint32 time variable cases. Hopefully, the animation stuff shouldn't stall the machine anymore.

[linux-audio-user] List of prefered apps...

by Russell Hanaghan

Hi all, Oh...FWIW.... I LOVE you guys! :) Meanwhile, I would like a list of preferred apps from anyone who responds. If you had an Audio LiveCD you could pop in your machine and boot it up, what would you most prefer to see there? I have sampled them all recently and while they look great, work reasonably well and have lots of stuff in them application wise, I'm not convinced the simplicity is as honed as it can be. 1. What are your top 10 critical "must have" audio apps? 2. What are your top 5 utility apps? 3. Considering a mid powered box, (say 1800mhz, 1 gig ram, etc) what is your favorite WM or desktop? 4. How many people *don't* have at least a DVD read only drive that you can boot from? YOur contribution would be very much appreciated. Regards, Russell

[linux-audio-user] LAC Recording Guidelines

by Esben Stien

It would be nice with some recording guidelines for LAC. Both for video and for audio. Maybe post a mail to linux-graphics-dev;). I'm talking about issues such as telling the participants to use big text on the slides. Maybe also, if the person is on the right side, maybe a vector overlay could be done, cheaply. It's also wise to position the camera such that there is little movement other than the speaker. This would save bandwidth and allow us to use higher resolution. Also, to not move the camera is nice. Also, to not allow questions from the audience without a microphone;). There are also many issues recording the speaker. -- Esben Stien is b0ef@e s a http://www. s t n m irc://irc. b - i . e/%23contact sip:b0ef@ e e jid:b0ef@ n n

[linux-audio-user] Re: [linux-audio-dev] List migration to linuxaudio.org : remaining issues.

by Marc-Olivier Barre

Hi, Two more question have been raised in another thread : > Wouldn't it be easier then to subscribe the consortium list address to > LAA? Agreed, it would be very easy... Ico, comments are welcome. > And by the way, it's been considered good practice to cross-post > announcements to LAA, LAU, and LAD. If this is the case, why aren't > announcements to LAA forwarded automatically to LAU and LAD? Good question. Normally there should not be any problems either for this. Comments are welcome. Once more, try to reply to both lists. __________________ Marc-Olivier Barre, Markinoko.

[linux-audio-user] Release Announcement, Musix GNU+Linux 0.99

by Marcos Guglielmetti

More info: http://www.musix.org.ar/wordpress/?p=64 Musix Project is proud to announce the release of Musix GNU+Linux 0.99, a new version of the 100% Free Software multimedia Operating System for artists and general users. This is the most stable and user friendly version until now. Since version 0.79, Musix GNU+Linux is focused on multimedia content creation and specially on music, that is: music production, audio edition, video edition, 3D animation, graphic design, image edition, web design… without forgetting the usual software for desktop’s PCs. Hundreds of software packages has been updated to the Debian/Etch’s versions. New additions include the audio/midi sequencer Muse and the sampler/sequencer/synthesizer SpiralSynthModular. The most remarkable programs in Musix 0.99 are: Ardour 0.99.3 (audio sequencer), Rosegarden 1.4.0 (audio/midi sequencer), Cinelerra (video edition), Bluefish (web design), GIMP (image manipulation), Inkscape (vectorial graphic design) and Blender3D (3D animation). System and desktop startup English and Spanish are 100% supported by Musix from the Live-CD out of the box, that means: you don’t need to install extra software packages to use the system in english or spanish. Other languages are only partially supported from the Live-CD out of the box, but we must remark the improvements in language support, specially German and Portuguese, as well as improvements in support for Finnish, Polish, Italian, Catalan and French. The file manager Rox-Filer, supports 22 languages. Since Musix 0.59, the system’s startup is 100% graphical. A “splash screen” was added in order to avoid confusing the new users with the less understandable system messages and the desktop is also started without need of any user action. A bug has been fixed: it was not possible to disable the audio hardware autodetection feature, but now the “nosound” switch works correctly (ej.: musix dma nosound). That can avoid system hangs when trying to load an incorrect driver at startup. Video Since Musix 0.99 we added the Xorg’s video autodetection method as a new “boot argument” (also called “cheatcode”): xorgmusix dma It’s in testing phase: in some computers this method works really better than the Knoppix’s one, also you can obtain 2D and 3D video hardware acceleration without installing or configuring anything. Sound Since Musix 0.59 the soundcard’s autodetection method was changed because the hotplug system was replaced by udev, following general trends of all GNU/Linux distributions. Now the autodetection it’s made by the old alsaconf script, but reformed to act automaticaly. If you want to avoid this autodetection method after installing Musix on your HD, just open a root terminal and type: rm /etc/rcS.d/S50sndconf-musix.sh So the system will boot faster. To enable it againg, type: ln -s /bin/sndconf-musix.sh /etc/rcS.d/S50sndconf-musix.sh Update without re-instalation Musix 0.99 should be able to update a previous version without reinstalling the hole system. You can start the Knoppix’s Installer in graphic or text mode, select the Package-Updater, then mark the packages to be upgraded using Synaptic and apply the changes. Abstract Musix 0.99 tries to offer the greater possible amount of 100% free software multimedia applications for creative users who need to express their works in different multimedia formats. For instance: nowadays for a music group it’s not sufficient with recording a song, perhaps the group needs to design a Web site, to film and to publish a video and to graphically design the cover of his CD or DVD. Musix it’s a complete artistic’s production factory, apt for the use in classrooms at educative establishments, in graphical design or recording studios, in video edition workstations, particular houses, state institutions or companies of any type. Upgraded software packages More than 350 software packages were upgraded from Debian/Etch, lets see just some of them: * Rosegarden4: 1.4.0-2 * Jackd: 0.101.1-2 * Gimp: 2.2.13-1 * Abiword: 2.4.5-2 * Konqueror: 3.5.5a.dfsg.1-6 * Icewm: 1.2.28-4 * Xorg: 7.1.0-12 * cinelerra: 2.1.0-2svn20070221 * KDE 3.5.5 New Software Packages * Inkscape; 0.45-1 (Description: vector-based drawing program) * SpiralSynthModular (An Object orientated modular softsynth / sequencer / sampler) * gnome-cups-manager (CUPS printer admin tool for GNOME) * acpi-support (scripts for handling many ACPI events) * RecordMydesktop y gtk-recordmy-Desktop (Captures audio-video data of a linux desktop session) * Muse (Qt-based midi/audio sequencer) * xjadeo (simple video player with jack sync) * mencoder (MPlayer’s Movie Encoder AVI/ASF/OGG/DVD/VCD/VOB/MPG/MOV/VIV/FLI/RM/NUV/NET) * Kompose (full screen task manager for KDE) * konq-plugins (plugins for Konqueror, the KDE file/web/doc browser) * 3ddesktop (”Three-dimensional” desktop switcher) * Kernel 2.6.17-2-multimedia (64studio’s kernel) * xlibmesa-dri (transitional package for Debian etch, 3D video acceleration) * Foobillard (a 3D billiards game using OpenGL) * Not installed yet into the Live-CD, it needs more testing: http://linux.ilmainen.net/musix/linux-2.6.21-rc2-SMP/linux-image-2.6.21-rc2… Full changelog https://www.musix.org.ar/wiki/index.php/Musix099_tasks Known problems into Musix 0.99 In some equipments it is possible that the printers cannot be configured correctly without installing more software packages, thus we created a script that installs those packages: get-more-print-packages If you want to install them open a root terminal and type: apt-get update get-more-print-packages * In order to compile software (for example: drivers) it’s necessary to install development packages that were removed… open a root terminal and type: restore-dev.sh * Some scripts still exist without translation. * kanotix-update doesn’t works Recommendations for the download It is recommended to use a download manager as far as possible, since it helps to manage recources better. You can use graphical ones like kget or gwget, or “wget -c” from a text console (terminal). -- Marcos Guglielmetti * Director del desarrollo de Musix GNU+Linux, 100% Software Libre * CD Donwload: (http://www.musix.org.ar/en/) * Colabora: http://www.musix.org.ar/wiki/index.php/Musix099_tasks * Videos, programas y otras cosas en: ftp://musix.ourproject.org/pub/musix/ * Reporte de errores a: https://www.musix.org.ar/wiki/index.php?title=Problemas-Bugs *IRC: #musix channel on freenode * http://autosus.wordpress.com/

[linux-audio-user] Midi recording

by Bob van der Poel

Hi guys. Hope you can help me figure this all out ... I've been reading this list for awhile and, even though I figure I'm a not-so-bad musician and fairly computer literate ... I have to admit that half the comments/questions I read here just turn to jelly in my brain. Anyway, what I want to do is to create some decent recordings using MMA backing tracks and me playing sax. So, what I'm doing right now is to play the MMA midi file though a keyboard and record that onto a little multi-track recorder. Then, I listen to the background track and record myself playing sax. Next, I transfer the tracks to the computer and do some rudimentary mixing with Audacity. Honestly, it doesn't sound all that awful (for my latest effort, http://mellowood.ca/music/recordings/). Biggest problem I see with this is that I can't tweak just the (for example) bass or piano in audacity since all the background is "mixed" into a stereo track. But, I'd like to do better :) So, I see a need to be able to split the MMA track into several audio tracks ... one for each MIDI track. So, question 1: what linux software will act as a synth which will split the midi out into separate audio tracks? I looked at timidity, and it doesn't appear to have that feature. If I've missed something there, I still have a problem with the quite awful default sounds it has ... so if I need to use timidity, where would I get better sounds. Or would I be better off to play/record the background multiple times though the hardware synth ... But I don't see how I'd ever get that synchronized. Question 2: Assuming that I have recorded a decent multi-track background, can I use audacity to record my sax playing off a mixer board? I've got a ICE1712 - M Audio Audiophile 24/96 audio card. Question 3: what questions have I forgotten to ask? Thanks. -- Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca
