[linux-audio-user] New Asus Ath. XP 2500 Delta 1010LT performance

by Russell Hanaghan

Okay.,,, So I bought this new box and have been working on getting it setup and stable for a few days now. When I run with Jack {.9.8.1 with Qjackctl 2.9} and Ardour {beta 17.1} at 48000khz I get mostly "pop" and crackle free operation in software monitoring (Which I have no choice to use as I'm using it as a live fx processor) But if I try to run at 96000 it pops and stuff even at higher intervals (512, 1024,etc). I guess I expected it should be able to do this no problem and I would get better fidelity as a result. What would the possible verdict be here? Thanks in advance R~

Your speaker system (and your ears) are probably incapable of resolving >20kHz signals in a live PA-type situation. Audio professionals ( mixers, mastering engineers, etc - not manufacturers ) are still undecided whether higher sampling rates is a good thing. If you are looking for higher fidelity sound, your time will be much better spent examining the gain stages of your system ( matching the impedances of inputs and outputs, etc ) rather than trying to get hicher frequency response though your DSP box. -Ben Loftis

[linux-audio-user] Audacity now works with JACK

by Daniel James

Hello all, I've been trying out the newly improved JACK support in Audacity and can confirm that it does work. If other people could give this some testing I'm sure it would help solidify the feature. Please consider joining the audacity-devel list and sending feedback. To build Audacity with JACK support you need to do this: cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/audacity login (hit the enter key when it asks for a password) cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/audacity co audacity (the above is all one line) cd audacity ./configure --with-portaudio=v19 --without-portmixer (edit src/Makefile and add this to the end of the LIBS line if it's not there): -lasound -ljack Then make and make install as usual. Start JACK, start Audacity and you should have a JACK option in Preferences under Audio I/O. You may need to disable the VU meters to get reliable playback on a slow machine - that option is on each meter's drop-down menu. Cheers Daniel

[linux-audio-user] normalize with sox

by luis jure

hello list, is there a way to normalize with sox in one pass? from the manual it seems that you must first find out the max value, and then pass 32768 (or whatever)/max to the vol effect... best, lj --

[linux-audio-user] Alsa / OSS support in Linux

by Alejandro Lopez

While on the topic, I seem to remember having read about a plan to incorporate Alsa in an upcoming version of the Linux kernel, that would be a plan to switch from OSS to Alsa as the "official" / preferred sound support in Linux. I think I heard about it something like 1 year ago as something that was in Linus' mind for the near future? Does this make any sense or am I talking b_llocks here? Reason I'm asking is because of your responses regarding Alsa support in the different distributions Mandrake / Debian / Fedora, I was thiking hey wait a second, I thought it was part of the kernel by now? Anyone familiar with the status of sound support? Cheers, Alex _________________________________________________________________ Horóscopo, tarot, numerología...

[linux-audio-user] ANNOUNCE: qjackctl 0.2.9 released!

by Rui Nuno Capela

Hi everyone, It's been a while, although this time there's not much. Just minor fixes, nothing very outstanding. However here it is, a new public release for QjackCtl, the little Qt (cutie:) application to control the JACK sound server daemon, specific for the Linux Audio Desktop infrastructure. Check it out from the usual place: http://qjackctl.sourceforge.net >From the changelog: - Patchbay socket dialog client and plug list option items are now properly escaped as regular expressions. - JACK callbacks are now internally mapped to QCustomeEvent's instead of using the traditional pipe notifications. - The system tray popup menu is now featured as a context menu on the main application window too. - The reset status option is now included in the system tray popup menu. - Server stop command button now enabled during client startup interval; this makes it possible to stop the server just in case the client can't be activated for any reason. - Top level sub-windows are now always raised and set with active focus when shown to visibility. Hope you enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org
