Re: [linux-audio-user] Making audio CDs - a simple way

by Sampo Savolainen

Quoting lanas <lanas(a)securenet.net>: > Folks, > > Not too long ago I've asked about how to make audio CDs. > ... Hi, Nice command line approach. I must be getting lazier with age as I prefer this: Applications->Sound & Video->Serpentine Audio CD Creator Drag ogg's into Serpentine Press "Write to Disc" This is not meant as a smug response to a well written script alternative, but more a testament to how the Gnome developers have succeeded in making this so simple.

[linux-audio-user] Late driver wakeup? Xruns? Why? Midi?

by Esa Linna

Yello, where should I search the problem, when Qjackctl gives me xruns and errors like these ################# 00:30:52.038 MIDI connection change. 00:30:52.051 MIDI active patchbay scan... load = 46.8052 max usecs: 2972.000, spare = 2361.000 delay of 2596.000 usecs exceeds estimated spare time of 2361.000; restart ... 00:31:07.437 XRUN callback (1). late driver wakeup: nframes to process = 512. ################# (Some lines edited) Problems so far with Bristol Audio and Qsampler, so I guess it has something to do with midi. Ardour works fine with audio, no Xruns. My setup: 1,2 ghz AMD 512 mb RAM Audigy 2 ZS plus SB Live! Edirol UM-1X Mandriva 2007 + multimedia kernel I had no problems with MDV 2006. -- ----------------------- http://www.emvg.net/esa http://www.emvg.net -----------------------

[linux-audio-user] rosegarden 4.1.4 crashes ubuntu

by Jeremiah Benham

For some reason when I use Rosegarden 4.1.4 in ubuntu it crashes my entire computer. I am not using any real time patch. I am just using the ubuntu kernel. Has anyone else experienced it? Do I need to install kubuntu desktop to get get it to work without crashing? I don't know how it could crash the system. Maybe I will try ssh'ing in later to make sure it is truly crashed and not just locking up X. Muse seems to work fine but I want Rosegarden to be able to work also. What else can I do to debug this? I am running 32bit ubuntu on an amd64. Thanks, Jeremiah

I was trying to type C-space, move the cursor using C-F (or similar), and then mark the end of the selection somehow. In other words, I expected that I could start a selection, move the cursor aribitrarily in any number of steps, and then somehow tell snd that "that is where I want the selection to end". I read that very section of the documentation, and it didn't seem to indicate any way to do that. As a beginner, I had not become comfortable to moving the cursor with numeric arguments. -Forest

How does one define the samples between two marks as a selection? I like being able to search through sound files based on a predicate. That's neat. Now, how can I search based on a predicate that applies to both channels of a stereo sound file? For example, what if I want to find time T such that both channels cross y = 0 when t = T? -Forest

[linux-audio-user] For all swedish lurkers out there

by Mathias Friman

I don't know how many swedish/norwegian speaking people there are on this list, but for those of you that do speak any of these languages, I would like to announce a "new" forum for Linux music, in affiliation with another part of the swedish hobby/semi professional music scene. The idea is to have some sort of first line support/discussion forum for newcomers and people not so fluent in english but eager to test Linux as their audio platform of choice. Well, here's a link: http://forum.studio.se/index.php?showforum=22 I hope to see you there. :) Regards, Mathias

[linux-audio-user] hdsploader / changing soundcards

by Georg Holzmann

Hallo! When I don't have plugged in my RME at bootup, I have sometimes the problem, that hdsploader is not able to upload the firmware onto the device: holzi@holzi:~$ hdsploader hdsploader - firmware loader for RME Hammerfall DSP cards Looking for HDSP + Multiface or Digiface cards : Card 0 : RME Hammerfall DSP at 0x34000000, irq 9 Upload firmware for card hw:0 Hwdep ioctl error on card hw:0 : Input/output error. Card 1 : Intel 82801DB-ICH4 Modem at 0x2400, irq 9 I searched a little bit and found this tip from Esben: http://lalists.stanford.edu/lau/2006/05/0436.html - which also works for me ... So my question, is there also a way to get hdsploader working without plugging out/in the card ? (and without a reboot) Thanks, LG Georg

To let C-space select both start and end of selection plus cancel it, put the following lines into your .snd-ls file: (bind-key (char->integer #\ ) 4 (let ((selstart #f)) (lambda () (let ((set-selstart! (lambda () (report-in-minibuffer (format #f "Selection start at ~A" (cursor))) (set! selstart (cursor))))) (if (c-selection?) (begin (set! (selection-member? #t) #f) (set-selstart!)) (if selstart (begin (c-set-selection! (c-selected-sound) 0 (min selstart (cursor)) (max selstart (cursor))) (report-in-minibuffer "") (set! selstart #f)) (set-selstart!))))))) (load-from-path "snd_conffile.scm") > BTW, I am not an emacs user.
