RE: [linux-audio-user] OT: need a video card

by Matthew Allen

I am currently using an nVidia Geforce 4 TI which you should be able to find under a 100bucks. Its not the latest whiz bang card but its very powerful and I have never had a problem with it. Vesa seems to love it too :) m. -----Original Message----- From: Joe Hartley [mailto:jh@brainiac.com] I'd appreciate it if some folks would email me off-list with their feelings about inexpensive (under $100 US) video cards that run well under Linux. Thanks!

[linux-audio-user] OT: need a video card

by Joe Hartley

The nVIDIA GForce2mx card in my studio machine is on its way out (weird streaks across the screen) and I'm temporarily using the sub-par onboard video do work. I'd appreciate it if some folks would email me off-list with their feelings about inexpensive (under $100 US) video cards that run well under Linux.

[linux-audio-user] Supporting Linux made music?

by Juhana Sadeharju

>From: Mark Constable <markc(a)renta.net> > >Where can I buy your music online, to help support music that >is produced with linux based software, wether I like your music >or not ? Many software would need presets, example sounds and loops, try-out demos. We need to support people who makes the software better. I don't see a point of giving money to people who only makes music.

[linux-audio-user] audacity 1.2pre3 and jack

by krozilo＠nm.ru

hi! i compiled audacity with ./configure --with-portaudio=v19 --without-portmixer and try to use with jack when i press "play" button, then auda not play audio. after EVERY pressing "play" button a pair: PortAudio client:out_0 PortAudio client:out_1 are added to jack_lsp list. f.e., after 4 pressing jack_lsp out: sh-2.05b$ jack_lsp alsa_pcm:capture_1 alsa_pcm:capture_2 alsa_pcm:playback_1 alsa_pcm:playback_2 PortAudio client:out_0 PortAudio client:out_1 PortAudio client:out_0 PortAudio client:out_1 PortAudio client:out_0 PortAudio client:out_1 PortAudio client:out_0 PortAudio client:out_1 sh-2.05b$ if i try to connect ports sh-2.05b$ jack_connect PortAudio client:out_0 alsa_pcm:playback_1 then audacity crash. Who success with pair audacity-jack? sorry for mistakes, regards.

[linux-audio-user] MalaWhaLa licence?

by Daniel James

Hello, Tom Schouten's music was recommended to me for DJ'ing from a laptop at an event we are doing in London, a 'GNU/Linux Audio Centre' at the Sounds Expo 2004 trade show. Although your website says the music is free to download, it doesn't say anything about live performance licensing, so I thought I'd check with you if this was OK. If you could let me know what the licence conditions are for DJ'ing - if any - I'd appreciate it. Cheers Daniel

[linux-audio-user] re: audacity

by BrbrOfSvl＠aol.com

->I think audacity uses the OSS emulation layer of ALSA, maybe there is a new "feature" (bug?) in the newest ALSA that breaks emulation for the HDSP? What sort of message do you get on startup? -- Fernando<- That's just it - there is no startup. It just hangs there with no message or any activity at all - until you interrupt the process or kill it in another shell. I'm going to try downgrading to the "latest stable release" (which is earlier than the 1.1-3 version on planetccrma) when the audacity site is back up - where did the ccrma audacity come from? Thanks, Matt

[linux-audio-user] audacity

by BrbrOfSvl＠aol.com

So, I'm running an HDSP/Multiface and a CCRMA redhat system. I can't get audacity to even start. It has worked just fine with past incarnations of the planetccrma kernel/drivers and this card/system. It works fine now with the onboard soundcard. What gives? Matt

[linux-audio-user] linux 2.6.1 realtime lsm, jackstart & ecasound success

by Eric Dantan Rzewnicki

I just completed a successful run of ecasound with my guitar_mix.ecs (attached) on my new box. This is a 15 minutes 5 track session, 4 tracks from disk, one live jack input. Three outputs: stereo wav, mono wav and live monitor. It uses amplify and panning effects controlled by ecasound generic oscillators. Details on the new box and it's current configuration: asus a7v8x-x athlon XP 2800+ (2071.203 MHz) 1.5GB PC2700 RAM 12GB / /dev/hda2 (actually a 40G disk) 160GB /mnt/audio/ /dev/hdc1 drives tuned 2GB swap /dev/hda1 onboard via8235 (M-Audio Delta-66 w/omni i/o -- still in old box) (ymfpci guillemot maxisound fortissimo -- midi only -- still in old box) debian testing (sarge) 2.6.1 (pre-empt on -- kernel.org sources compiled via make-kpkg) realtime-0.0.2 lsm alsa-1.0.2 (drivers, lib, envy24control, tools) drivers: ./configure --with-isapnp=no --with-sequencer=yes --with-oss=no \ --with-cards=dummy,virmidi,ice1712,ymfpci,via82xx libsndfile-1.0.5 from tar.gz. debian only had 1.0.4 jack-0.94.0 ./configure --enable-capabilities --enable-optimize \ --with-default-tmpdir=/mnt/ramfs/ --disable-portaudio ecasound-2.3.2 ./configure --enable-pyecasound --disable-oss --disable-arts \ --with-largefile I started jackd via jackstart like so: jackstart -v -R -d alsa -d via82xx -r 44100 -p 128 -n 3 I run the ecasound session from a script that does some pre and post processing. It assembles the 4 wav input files from other wav's and cuts the output files down to randomly selected 5 minute chunks, fades in and out the beginnings and ends, normalizes and encodes the stereo wav to ogg. The whole session ran on this onboard soundcard without xruns. I switched desktops numerous times in openbox3 and even switched out of X to tty2 to login and change my hostname back (I had changed it while in X and new apps weren't able to start because they couldn't connect to the display. duh ... 8) ). The session ran flawlessly. I'm not exactly sure what the stats jackd puts out when run verbosely mean, but I know the results I saw mean I'll be able to run this session with many more effects at lower latency than I could on my old box ... _And_ I don't have to do it as root! yay! :) The old box is a PII 400 w/768M PC100 RAM. On that box the whole session including pre and post processing takes around 21 minutes. On the new box that overhead is cut way down with the whole session taking only 16 minutes 20 seconds (only 1 min, 20 more than the actual recording time). While running jackd reports load averaging (just measured visually from jackd output, not hard numbers) around 7.5 with max usecs ~220. On the old box using my delta66 I have to run at -p 256 to avoid xruns in this session, load averages around 22 and max usecs around 1350. Admittedly, much of this performance gain is related to the new hardware. But, still , it's very cool that all this newish stuff (lsm, latest alsa, latest ecasound, latest jackd, 2.6 kernel) is working well In other testing with the via chip I've had jack running as low as -p 32 -n 3 with just a couple jack_metro's connected. I have to go down to -p 16 to get a few xruns. Not until -p 8 do things start to get really bad. /proc/interrupts says the card's on IRQ 4, too. I have a few more things to install, configure and test before I move my delta66 and midi setup over to the new box. But, these initial tests are very exciting. I just had to share. Thank you to all the developers for all this excellent software. And thanks to all the list members, too. :) -Eric Rz. # eric(a)zhevny.com guitar_mix chainsetup file ### general -b:128 -B:rtlowlatency -n:guitar_mix -X -t:902.802 ### audio inputs -a:1,6,11 -i:track1.wav -a:2,7,12 -i:track2.wav -a:3,8,13 -i:track3.wav -a:4,9,14 -i:track4.wav -a:5,10,15 -i:jack_alsa #-a:5,10,15 -f:16,1,44100 -i alsahw,0 ### audio outputs # live output -a:1,2,3,4,5 -f:16,2,44100 -o jack_alsa #-a:1,2,3,4,5 -f:16,2,44100 -o alsahw,0,0 # file outputs ### FIXME: change this output to .ogg when crop and fades work -a:6,7,8,9,10 -f:16,2,44100 -o:/mnt/audio/in_progress/guitar_mix/stereo_out.wav -a:11,12,13,14,15 -f:16,1,44100 -o:/mnt/audio/in_progress/guitar_mix/mono_out.wav ### chain operators and controllers # live output -a:1 -erc:1,2 -epp:0 -kos:1,0,100,0.02,0 -ea:0 -kos:1,0,200,0.01,0 -a:2 -erc:1,2 -epp:0 -kos:1,0,100,0.04,0 -ea:0 -kos:1,0,200,0.02,0 -a:3 -erc:1,2 -epp:0 -kos:1,0,100,0.06,0 -ea:0 -kos:1,0,200,0.03,0 -a:4 -erc:1,2 -epp:0 -kos:1,0,100,0.08,0 -ea:0 -kos:1,0,200,0.04,0 -a:5 -erc:1,2 -epp:50 -ea:205 # stereo file out for .ogg -a:6 -erc:1,2 -epp:0 -kos:1,0,100,0.02,0 -ea:0 -kos:1,0,200,0.01,0 -a:7 -erc:1,2 -epp:0 -kos:1,0,100,0.04,0 -ea:0 -kos:1,0,200,0.02,0 -a:8 -erc:1,2 -epp:0 -kos:1,0,100,0.06,0 -ea:0 -kos:1,0,200,0.03,0 -a:9 -erc:1,2 -epp:0 -kos:1,0,100,0.08,0 -ea:0 -kos:1,0,200,0.04,0 -a:10 -erc:1,2 -epp:50 -ea:205 ### crop and fade in/out ### generate an effects preset file for this in preprocessing #-a:6,7,8,9,10 -ea:0 -kl:1,0,100,4,0,0,10,1,290,1,300,0 # mono file out for pool -a:11 -ea:0 -kos:1,0,200,0.01,0 -a:12 -ea:0 -kos:1,0,200,0.02,0 -a:13 -ea:0 -kos:1,0,200,0.03,0 -a:14 -ea:0 -kos:1,0,200,0.04,0 -a:15 -ea:205 ### crop and fade in/out ### generate an effects preset file for this in preprocessing #-a:11,12,13,14,15 -gc:$pos,300 -ea:100 -klg:0,0,100,4,0,0,10,1,290,1,300,0
