[linux-audio-user] commandline info viewer ?

by Michelle Konzack

Hello *, I have made a BASH script which I use to view varius attachments in my MUA (mutt). Because I get often mp3 I have made this: ____( '/usr/bin/tdfileview' )_________________________________________ / | elif [ `echo "$1" |grep -E ".mp3$"` ] || [ `echo "$1" |grep -E ".mpa$"` ]; then | # MPEG audio | # | echo $"MPEG ID3 Tag:" | echo $"=============" | mp3info -x -p "File: %fnTitle: %tnTrack: %nnArtist: %anAlbum: %lnYear: %ynComment: %cnGenre: %g (%G)n" "$1" | echo "" | echo $"MPEG technical informations:" | echo $"============================" | mp3info -x -p "Media Type: MPEG %3.1v Layer %LnRate: %r KB/s, %q KHz (%o)nEmphasis: %enCRC: %EnCopyright: %CnOriginal: %OnPadding: %pnTime: %m:%snGood Frames: %unCorrupt Frames: %bn" "$1" | else \______________________________________________________________________ Which works perfectly and fast. Now I am searching for a similar commandline wave-info viewer. Does such proigram exist ? It must be in the Debian distribution.

[linux-audio-user] How to automate hdsploader on 2.6 kernel?

by ico＠fuse.net

Hi all, In the light of my upcoming presentation at ICMC, I am wondering whether it is possible to somehow automatically start hdsploader as soon as the snd-hdsp cardbus has been connected? I tried adding the snd-hdsp executable shellscript to the /etc/hotplug/pci folder but that apparently did absolutely nothing and since there is no suggested syntax for the pci.usermap file (at least not under the mandrake), I have no idea how to make hotplug aware of it. Furthermore, it seems that hotplug has very little or nothing to do with the cardbus as nowehere in the hotplug script do I find the syntax for this dmesg output: PCI: Enabling device 0000:02:00.0 (0080 -> 0082) ACPI: PCI interrupt 0000:02:00.0[A] -> GSI 17 (level, low) -> IRQ 17 Hammerfall-DSP: no Digiface or Multiface connected! card initialization pending : waiting for firmware Hence, I've been wondering what do I need to do to automate hdsploader as soon as the cardbus has been connected? I would greatly appreciate any help I can get! Best wishes, Ico

[linux-audio-user] [ANN] realtime-lsm-0.8.3 beta test

by Jack O'Quin

The realtime Linux Security Module is an installable kernel module that enables realtime capabilities for any 2.6 kernel without needing to directly patch the kernel. It was originally written by Torben Hohn and Jack O'Quin, who make no warranty concerning the safety, security or even stability of your system when using it. It is provided under the provisions of the GPL. We are preparing a new version of this LSM for inclusion in an upcoming 2.6.x kernel version. Special thanks to Jody McIntyre and Chris Wright for many improvements to the LSM, and to Lee Revell for patiently shepherding it through the kernel patch acceptance process. No one *needs* to use this new version, the older ones work fine. But it would help for some of you to download a beta version and try it out. Two test files are available, use either one. The first is a tarball[1] for building stand-alone, like previous LSM releases. This version no longer supports kernels earlier than 2.6.4. The second is a patch[2] for the current (2.6.10-rc1-mm2) development kernel. This patch should apply cleanly against any recent kernel since 2.6.9-mm1, and should work with some earlier ones with a little fiddling. [1] http://www.joq.us/realtime/realtime-lsm-0.8.3.tar.gz [2] http://www.joq.us/realtime/linux-2.6.10-rc1-mm2-rt2.patch.gz There are some small changes to the user interface. (*) The `allcaps' option is no longer supported. It was an unnecessary security exposure to include in standard kernel sources. Consequently, you will not be able to use the `jackstart' command with this version, unless you are running a recent CVS version of JACK (>=0.99.2). There is really no need for `jackstart' with realtime-lsm, invoking `jackd' directly works fine. (*) Recent kernels (>=2.6.9-mm1) externalize module parameters in sysfs. With this feature, realtime-lsm options can be queried and set via files in /sys/module/realtime/parameters, each named after the corresponding parameter (any, gid, mlock). Please report directly to me (i.e. mostly off-list) any problems or successes you have with this version. Thanks, -- joq

[linux-audio-user] WMA

by Alejandro Lopez

>By the way, on the page you talk about Winamp for M$ and now it's time to >talk about www.zinf.org, which is *really* free (as in free speech ;) Hi, This post reminds me I need to burn an audio CD from a set of .WMA files I've been given :-((( So far, the only thing I've been able to do with these is playing them with Windows Media Player (and putting them in an audio tape, remember those?). I absolutely fail to understand why, if I have some codec installed (and I have since I can play the files), I still can't do a file conversion to a raw waveform I could then use to burn the audio CD. As for Linux, none of the tools that come with DeMuDi recognizes the format either. Any suggestions, apart from asking the guy to be nicer to everyone by using a convenient format?

Barcelona, Spain http://www.icmc2005.org/ ------------------------------------------------------------ SUMMARY OF DEADLINES Music, video, and installations -- February 5, 2005 Papers, posters, and demonstrations -- March 5, 2005 Panels, workshops and special events -- April 5th, 2005 Exhibitors -- June 5th, 2005 CALL FOR PARTICIPATION The Phonos Foundation, the Pompeu Fabra University of Barcelona, and the Higher School of Music of Catalonia in conjunction with the International Computer Music Association, is proud to announce ICMC 2005. The conference will take place in Barcelona, Spain, from the 5th to 9th of September 2005, with pre-conference workshops on September 1st and 2nd. ICMC is the pre-eminent annual gathering of computer music practitioners from around the world. Its unique interleaving of professional paper presentations and concerts of new computer music compositions creates a vital synthesis of science, technology, and the art of music. By choosing 'free sound' as this year's leitmotif, we aim to emphasise the idea of freeing sound from its current aesthetic, technical and legal confines. We wish to promote an open discussion on the extent to which sound is considered a community asset -- an asset that belongs to society and cannot be privatised. Thus, we encourage contributions that emphasise these and related topics. We invite original contributions in all areas of the computer music field in a number of formats. However, we are also open to any proposal, and encourage all submissions, including those that do not fit the categories below. We issue the following calls: * Call for music, video, and installations (deadline February 5, 2005) We invite submissions of electroacoustic music, video, and installation works that reflect the diversity of the field. Opportunities exist to combine digital resources with a variety of instrumental ensembles. For further details visit http://www.icmc2005.org/index.php?selectedPage=76 * Call for papers, posters, and demonstrations (deadline March 5, 2005) We invite submissions for papers, posters, and demonstrations examining the aesthetic, compositional, educational, musicological, scientific, or technological aspects of computer music and digital audio. For further information visit http://www.icmc2005.org/index.php?selectedPage=73 * Call for panels, workshops and special events (deadline April 5th, 2005) We invite proposals for panel sessions, workshops and special events, especially those with relevance to the conference theme of 'free sound'. * Call for exhibitors (deadline June 5th, 2005) The conference will provide a forum for the world's leading music technology companies to showcase their latest product information and for schools and institutions to highlight their educational programs. We invite submissions from interested parties. To promote the idea of 'free sound', the organisers of ICMC 2005 are setting up the Free Sound Project, a website dedicated to the sharing and usage of copyleft [1] sounds. Thus, we are making a special call for copyleft sounds with no specific deadline. For more information, visit http://www.icmc2005.org/ in the near future. For detailed information on the conference, and submission formats, visit http://www.icmc2005.org/ To keep up to date with all of the latest news and information about ICMC 2005 please subscribe to our mailing list by visiting http://www.icmc2005.org/index.php?selectedPage=64 We are looking forward to your contributions!

My multiface AUDIO works (save for hdspmixer not displaying, but unmuting), Just not MIDI. For info on getting the audio to work checkout my page above for tips on kernel building. Im running with a 2.66 ms latency! (but with other problems as well...) > Furthermore, if I stop alsa and run hdsploader by hand, I get a kernel > oops and the system, which is otherwise very stable, becomes unstable > and requires a reboot. You can only load the firmware once. If you try to load firmware for the multiface after its already been loaded bad things happen. Takashi Iwai fixed my multiface/cardbus and now < 2.6.9-rc3 should contain that fix... Good Luck! -thewade
