[linux-audio-user] xruns from ardour + softsynths

by Atte André Jensen

Hi I played a bit with ardour to the extend that I ended up with 12 tracks of backing vocals (playing at the same time) + a lead vocal + some talk + zynaddsubfx (running two pads + bass) + specimen (drums) + ams (lead) + seq24 for midi. This is too much for my setup, I get audible xruns every now and then (just after loading the song often, after a while about every minute, with no window activity) and qjackctl reports them all the time. However the cpu usage is below 50% so I'm led to believe that with some fine tuning it should be possible. My computer is a Pentium M 1.6 w 1G ram, 100G 7200 RPM HD running xubuntu/dapper/6.06 and I use the (I know shitty) onboard i8x0 . Basically all I did was: echo @audio - rtprio 99 >> /etc/security/limits.conf echo @audio - memlock 250000 >> /etc/security/limits.conf echo @audio - nice -10 >> /etc/security/limits.conf I think my soundcard works at 48000 hz, but I run jack at 44100 because of previous (now resolved) problems with zynaddsubfx. Could this be the cause of my problems? hdparms says: root@ajstrup:~# hdparm /dev/hda /dev/hda: multcount = 0 (off) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 16383/255/63, sectors = 195371568, start = 0 And: root@ajstrup:~# cat /proc/interrupts CPU0 0: 1435743 XT-PIC timer 1: 3861 XT-PIC i8042 2: 0 XT-PIC cascade 3: 28534 XT-PIC irda0 7: 0 XT-PIC parport0 8: 3 XT-PIC rtc 9: 916321 XT-PIC acpi 11: 2391090 XT-PIC uhci_hcd:usb1, uhci_hcd:usb2, uhci_hcd:usb3, ehci_hcd:usb4, ath0, yenta, Intel 82801DB-ICH4, yenta, eth0, radeon@pci:0000:01:00.0 12: 2488 XT-PIC i8042 14: 82500 XT-PIC ide0 15: 98767 XT-PIC ide1 NMI: 0 LOC: 0 ERR: 0 MIS: 0 This is how jackd is setup (run through qjackctl): atte@ajstrup:~$ cat .jackdrc /usr/bin/jackd -v -R -P65 -dalsa -dhw:0 -r44100 -p256 -n2 -S Any ideas? -- peace, love & harmony Atte

[linux-audio-user] [admin] spam handling on the linux-audio-* lists

by Joern Nettingsmeier

hi everyone! just fyi, the amount of spam in the moderation queues has risen to such an extent that the server admin, douglas repetto of columbia university, has implemented an auto-clear function for the queues. that means: if your message is not forwarded to the list, it will be dead, gone and forgotten. this happens either if you are using a non-subscribed address to post (regardless of whether you are subscribed with another account, even if it's in the same domain, i.e. if j(a)example.com is legitimate, j(a)dork.example.com will bounce), or if mailman determines you are posting html. due to a misunderstanding, this auto-nuking has been active on linux-audio-announce as well for the past couple of days. so if you tried to get an announcement out, please resend - the old one went straight to the bit bucket. regards, jörn -- jörn nettingsmeier home://germany/45128 essen/lortzingstr. 11/ http://spunk.dnsalias.org phone://+49/201/491621 if you are a free (as in "free speech") software developer and you happen to be travelling near my home, drop me a line and come round for a free (as in "free beer") beer. :-D

There is no copyright infringement involved in this tune that was posted. Although he did use samples from copyrighted works, that alone does not constitute copyright infringement. I won't go ahead and cite US copyright law (and it's not some little loophole either), but basically since there is no money being exchanged for this song and we as listeners are playing this in a private setting, this entire thing is perfectly legal. I won't/can't comment on originality of this work, as I'm not familiar with most of the artists Andrew cited. But I did like it, Andrew. The moral issue is another thing... but Andrew made it very clear that it wasn't original source material, he cited the artists he used, and he made no attempt to pass it off as his own. So anyway, as I said, I didn't write this to start a debate, I won't be posting anything else on this thread. I just felt something should be said about the legality of this. -Mike P.S. The system in place was meant to protect publishers, not artists. But that's another topic we can discuss elsewhere.

[linux-audio-user] problem with LASH

by Atte André Jensen

Hi I spend most of last night playing with LASH. I patched zyn, specimen and seq24 and also use lash_panel + patchage. However I have a problem. Often (almost precisely every other time) closing a session will make some programs (mostly zynaddsubfx) hang. They can't be killed with xkill or killall. If zyn is the hanging program it will still appear in qjackctl's midi connection. This will also take jack and lashd down, and this is output to the terminal where lashd was started: Project jesus_kristus removed LASH event: LASH_Quit Disconnected from Jack Disconnected from Alsa [JACK sync disabled] Writing [/home/atte/.seq24rc] JACK error: zombified - calling shutdown handler jack_mgr_shutdown_cb: JACK server shut us down; telling server to quit Cleaning up zombified - calling shutdown handler cannot read result for request type 7 from server (Connection reset by peer) cannot read result for request type 7 from server (Connection reset by peer) JACK error: cannot send request type 7 to server JACK error: cannot read result for request type 7 from server (Broken pipe) jack_mgr_destroy: could not deactivate jack client JACK error: cannot send request type 7 to server JACK error: cannot read result for request type 7 from server (Broken pipe) Finished So I figure it's a problem with lash in zynaddsubfx (if I only use specimen it seems to work very reliable). My questions are: 1) Is there a way to really kill a hanging zynaddsubfx, when killall and xkill won't work? 2) Does anyone have lash working reliable with seq24, sepcimen and zynaddsubfx? Which lash patches did you apply to which version, and did you have to do anything else? What distro? How do you start jack and lash? Which kernel? 3) I tried with both lash patched I could find (zyn-2.2.1-lash-jackmidi-060605.diff and zyn_lash-0.5.0pre0.diff) with ZynAddSubFX-2.2.1.tar.bz2. Is there something newer/better/different I should try? 4) Any ideas what could be wrong? Maybe it's something completely -- peace, love & harmony Atte

[linux-audio-user] [AN] QLoud-0.1 - measuring loudspeaker response

by Andrew Gaydenko

Hi! I have wrote this app for own audio-DIY use. Probably, somebody else will find the app useful too. I'll be happy in such case :-) Source: http://gaydenko.com/qloud/qloud-0.1.tar.bz2 Screenshot (180KB): http://gaydenko.com/qloud/shot01.png ===== README ====== QLoud is a tool to measure a loudspeaker frequency response. Writing this app is inspired by excellent applications written by Fons Adriaensen: http://users.skynet.be/solaris/linuxaudio/ Theoretical background belongs to Angelo Farina: http://pcfarina.eng.unipr.it/ In particular, this method was used: http://pcfarina.eng.unipr.it/Public/Papers/134-AES00.PDF Few hints: - move mouse above "?" sign at plot window and wait, - to delete measurement, use context menu on mesurements table, - to see what the app do, just connect app's JACK ports and try, - to see what your sound card do, use loopback for line in/out, - using "very smooth" fractional octave smoothing is hungry for CPU. So be patient when select more rather 1/3 octave smoothing (1/3 octave and less smoothing is rather interactive). Feedback: Please, add "QLoud" to your message subject. My email is: a(a)gaydenko.com ===== INSTALL ===== Requirements: - QT4 ( http://trolltech.com/ ), I use 4.1.4 version, - Qwt ( http://qwt.sourceforge.net/ ) from current CVS tree (probably, last official CVS qwt5 snapshot will work too), - JACK ( http://jackaudio.org/ ), - sndfile ( http://www.mega-nerd.com/libsndfile/ ), - fftw ( http://www.fftw.org/ ). Installation: - look in src/src.pro to modify include dirs if you want, - run qmake make 'qloud' excecutable will be in 'bin' directory.

[linux-audio-user] Plugins for bass

He all, I need to improve the bass tracks recorded with ardour. Compressor and enhancer for example. I usually use SC4 and SE4 but I hear some metallic nois and I'm not satisfied at all.
