[linux-audio-user] [OT] any Xemacs users here ?

by Dave Phillips

Greetings: I'd like to start learning more about emacs, and the Xemacs package has been recommended. I've installed it without problems, but I have some questions for an experienced user. Can anyone on this list help out ? I'm especially interested in using it with Common Music and Csound. Best regards, == Dave Phillips The Book Of Linux Music & Sound at http://www.nostarch.com/lms.htm The Linux Soundapps Site at http://linux-sound.org

[linux-audio-user] Syncronizing Audio file and sequencer

by linuxmedia4＠netscape.net

Greetings, I'm sure that (one) of the answers to my question is "jack will do the trick" but I would (first) like to know any program that will do it on it's own. I haven't used jack yet because I have my hands full testing all the many apps out there and want to know what they do on their own. When I have the chance to try differnt apps and see what's out there, then I will give jack the time it deserves (I hate "kinda, sorta" knowing a program). Anyways, can I get input from people about which app they find works best with syncronizing (multitrack) audio files (recording and playback) with sequencing. Of course, I will need the flexibility to record a sequence file along with audio files also. So far I've only tried Jazz and it doesn't allow you to playback the audio file from the middle. You are forced to start at the beginning of the file. So obviously, it's important to be able to start in the middle of an audio file. And hey... if it complile with little trouble with SuSE 8.1, it looks like we got a winner. Who knows, it may even come with the distrob. (-: Thanks, and I've gotten a lot out of being on this list.

If you app does not support Jack but Alsa, you can try ameter (an alsa plugin with a display taken from Meterbridge dpm): http://perso.club-internet.fr/lgeorget/ameter.html I would be interested in feedback about installation , usage etc...

[linux-audio-user] JACK 0.70.4 release

by Taybin

JACK 0.70.4 release JACK is a low-latency audio server, written primarily for the GNU/Linux operating system. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin"). JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation. CHANGES: qjackconnect/jack_lsp bug fixed. now can use either SysV or POSIX shm methods. Linxu 2.4.4 is required for the POSIX method. Defaults to SysV, but can be switched with a ./configure option (--enable-posix-shm) new --enable-optimize configure time flag, for compiler optimization. jack_set_buffer_size_callback() de-deprecated. added port metering API. added option --timeout (OR -t) for client timeout. The default time is as before: 500 msec. jack_lsp now has usage (-h or --help) and version (--version) options. various bug fixes and documentation updates. CAVETS: The shm code requires the tmpfs kernel module either loaded or compiled in. A tmpfs filesystem must be mounted as well. This can be done by adding: tmpfs /dev/shm shm defaults 0 0 to /etc/fstab and running "mkdir /dev/shm; mount /dev/shm". In versions of linux prior to 2.4.4, tmpfs was known as shmfs. Client programs compile with the previous stable release (0.61.0) will need to be recompiled to work with 0.70.4. Client programs now need to also link against librt. That library should be automatically included via pkg-config. Taybin Rutkin

[linux-audio-user] Wavio, Onkyo

by Thomas Sinczak

Hi I am planning to buy a USB Sound Card - or as they call it USB Audio Digital Processor. on ALSA page I have found a driver for Creative Extigy device, but I would rather buy Onkyo-Wavio SE-U55X(S) device: http://www2.onkyo.co.jp/product/products.nsf/view/72D59994EC1AE0BC49256BBF0… http://www2.onkyo.co.jp/what/news.nsf/view/se_u55x?OpenDocument http://ascii24.com/news/i/hard/article/2002/04/03/634895-000.html or google < SE-U55X(S) I would like to ask if there is any known driver? I have second less important question > does any of you think this Wavio system with Vector Linear Shaping Circuitry can deliver better sound than Creative Extigy?

[linux-audio-user] RE: Capture with DIGI9636 Hammerfall Light and playback with PCI 128

by Martin Buechler

Hi Steve, Paul, Mark Since I started this thread, I want to thank you for your interesting answers. What I understand is: The capturing/playback is tightly coupled to the same physical device, except one makes it to tie two different ones together by providing an external clock/sync or propagating an existing clock/sync-source. The solution introduced by Mark connecting the s/pdif clocks sounds _too interesting_ for my audio skills, that's why I decided to order an AEB/O-4 for the 9636 as Steve suggested, since the rest of my setup is completely analog ;) and my first goal still is to reduce delay to zero, when recording overdubs with analog instruments.

[linux-audio-user] tempo finder

by Antonis Galanopoulos

Hi all, Does anybody knows a program tha could help me find out the tempo of a given audio file ? Whay i want to do is extract loops from large audio files (usually mp3). So I get my selection, enter the length in bars and the sig and I get the BPM. Or something similar. What cames in mind is recycle. Does any of the wave editors (sweep, audacity, rezound) available can do something like that?

[linux-audio-user] xruns: file system ext3 --> reiserfs?

by derek holzer

dear list, i'm running Debian kernel version 2.4.20 with ext3 an an Asus L3 laptop with a Hammerfall HDSP, and my xruns using Jack are frequent and nasty! i would say in the nieghborhood of every 10-20 seconds, i get an xrun of 10-200 ms. i have done all the hdparm stuff, all the necessary low latency and preemptive patches, and have everything set up to run realtime capabilities for Jack. the problem, of course, is that with ext3 and kernel 2.4.20, the machine totally freezes when i do a "jackstart --realtime". [this is documented somewhere, so i know it's not just me!] so, i figure my solution is to convert the filesystem of my main partition to reiserfs, thereby allowing me to gain from its better journal [i.e. less disk activity, i guess] and the ability to use realtime capabilities. and here is where i start to feel like a dumb newbie :-) if my main partition is /dev/hda2, and i am working from another [temporary] root file system in /dev/hda6, how can i back up /dev/hda2 to /dev/hda7 and put it back again after doing the ext3-->reiserfs conversion WITHOUT transferring back over the old file system? i tried dd if=/dev/hda2 of=/dev/hda7, but when i mounted /dev/hda7, it was turned into an ext3 filesystem, although i had already made it reiserfs. i assume that means if i changed dev/hda2 to reiserfs and moved the backup copy there again, it would be ext3 all over again. i tried a few things with cpio that didn't work, and i am not sure i have the syntax right with tar. can someone please help me out here? thx. derek
