[linux-audio-user] pam modules / non root users can't get realtime privileges.

by Marcos Guglielmetti

Hi I see this: /lib/security/pam_unix.so /lib/security/pam_unix_acct.so /lib/security/pam_unix_auth.so /lib/security/pam_unix_passwd.so /lib/security/pam_unix_session.so lsmod | grep pam (nothing) I dont know how does it works... I have: apt-cache policy libpam-modules libpam-modules: Instalados: 0.79-4 Candidato: 0.79-4 Tabla de versión: *** 0.79-4 0 990 ftp://ftp.fr.debian.org testing/main Packages kernel: Linux 2.6.20-rc5-rt2 #2 SMP PREEMPT Mon Jan 15 22:24:12 EET 2007 i686 GNU/Linux But, non root users can't get realtime privileges. Lee told me to use something like this into /etc/security/limits.conf @audio hard rtprio 99 @audio hard nice -20 @audio soft nice -20 @audio hard memlock 500000 My user is into the audio group, of course But the problem is still here: no realtime JACK audio for non root users... I cant install an Ubuntu libpam-modules into this system, because it will break the package dependency system.

[linux-audio-user] [ANN] Aqualung 0.9beta7 released

by Tom Szilagyi

The authors are proud to announce the release of Aqualung 0.9beta7. Aqualung is an advanced music player originally targeted at GNU/Linux, today also running on other operating systems such as FreeBSD and MS Windows. We are striving to create one of the finest music players available, with respect to sound quality, stability, features and ease of use. This release is the latest in a series of beta releases on our way to the future stable release of Aqualung 1.0. It adds significant new functionality as well as important bugfixes. The ChangeLog for this release is listed below. Homepage: http://aqualung.sf.net Enjoy, Tom 2007-02-05 Tom Szilagyi <tszilagyi at users dot sourceforge dot net> * Aqualung 0.9beta7 http://aqualung.sf.net This release introduces important new features and bugfixes. Main reasons for upgrading: * CD Audio support, complete with CDDB, CD-Text, etc. You can play Audio CDs directly, or rip them to WAV, FLAC, Ogg Vorbis or MP3 (CBR/VBR, gapless via LAME) complete with tagging, on the fly. * Revamped Music Store Builder: better operation, greater flexibility. * Support FFmpeg library enabling the recognition of numerous formats e.g. AC3, AAC, WMA, WavPack, and the soundtrack of many video files. * Replaygain support for APEv2 tags. * Ability to set looping range when looping a single file. Should be useful for people playing along a recording, trying to learn phrases of a song. * Adding music to the playlist is now a non-blocking, interruptible background operation. * Drag-and-drop files from external sources (Nautilus, Konqueror, etc) into the Aqualung playlist. * Several critical memory leak fixes. * Numerous GUI refinements; fixed some rare bugs in engine, too. * Support for building against the new FLAC 1.1.3 API. * Aqualung operates correctly on bigendian systems (32 and 64 bit). * Running natively on MS Windows. A port of TAP-plugins is included in the installer. See http://aqualung.sf.net/win32 for more. NEW LIBRARY DEPENDENCIES: All of these are optional; Aqualung will build without them, disabling the functionality they provide. * libcdio >= 0.76 is required for CD audio support. http://www.gnu.org/software/libcdio/ * libvorbisenc for ripping into Ogg Vorbis. http://www.xiph.org/ogg/vorbis/ * libmp3lame for ripping into MP3. http://lame.sourceforge.net/

[linux-audio-user] Which distribution? (Used to be DeMuDi)

by Asbjørn Sæbø

Hi, and sorry for the newbie-ish subject. I have mostly been away from Linux audio for the most part of a year, and things seems to have changed during that time. So, now I am wondering where to pick up. DeMuDi, the distribution which I used to use, seems to have little activity. Is is maintained in such a way that it is sensible to go with it again? And if not so, what other suggestions do you have for a distribution for audio work? (Studio64 is out of the question, as I have no 64-bit hardware.) Simple low-latency setup is appreciated, as is something Debian-based and quite up-to-date. With kind regards Asbjørn Sæbø

[linux-audio-user] [ANN] Aldrin 0.10 (Venus)

by Leonard Ritter

Aldrin is an open source modular music sequencer/tracker for the GNU/Linux operating system. We're proud to announce the release of Aldrin 0.10 (Venus). This release is the second release of the "planet" release cycle, and introduces a lot of new features to Aldrin. Here is a short overview of the most relevant features introduced in this version: * The vertical-time sequencer view has been replaced by a horizontal-time sequencer view to get more screen real estate. It is pretty similar to what you might be used from commercial sequencers, the difference is that it's controllable by keyboard only. * Support for The Freesound Project. Browse and download samples on the fly without leaving Aldrin. * The pattern editor has scrollbars now, so you can easily reach that itchy back of the M4wII even with a low screen resolution. * Support for loading FLAC, AIF and MP3 samples. * Aldrin recognizes now multiple MIDI inputs. * A new set of small icons. * The CPU monitor has been improved. You get proper numbers now, and a nifty graphical gauge. * Redrawing speed has been speed up in the router and sequencer views. * Various wording changes. * Numerous bugs fixed. Enjoy this new version and visit us on #aldrin on freenode.net, or subscribe to the Aldrin mailing list. http://www.leonard-ritter.com/announcement_aldrin_0_10_venus -- Leonard Ritter -- Freelance Art & Logic -- http://www.leonard-ritter.com

[linux-audio-user] Advice about dithering

by yves＠jazzcomputer.org

Hi. Could the wise members of this list give me an advice ? :) Is it a good practice, or even useful, to activate dithering in jackd when exporting a session to a wave file in Ardour ? And which kind of dithering is the most efficent, or the most commonly used, between the three types available ? I imagine that the same type must be chosen in Jackd and in Ardour, if the two ones must be activated... Thank you very much in advance, Y.

[linux-audio-user] looking for the most competitive bastard (you have ever seen)

by Burkhard Wölfel

Hi all, Hi Ron P. one of my favourite songs got lost in a disk crash some time ago. It's a song by Ron Parker containing the line "I'm the most competitive bastard you have ever seen". Can somebody point me to an url if it's still available for download? If not, Ron, could you repost? - Burkhard

[linux-audio-user] Does the ESI RoMI/O work with USB 1.1?

by linuxmedia4＠netscape.net

I googled forever and can't find this info anywhere. Does the ESI RoMI/O work with USB 1.1? If so, is 1.1 sufficient for decent midi recording? My demands are pretty low. I will just be connecting my midi keyboard to it and recording in MuSE. The data will only be going in one direction (no external devices will be triggered). Thanks, Rocco
