[linux-audio-user] OT: Hardware Question-- Is this a 64bit system?

by The Other

I bought a recycled HP x4000 Workstation with dual Intel Xeon processors and Intel 860 Chipset. (Came with no manuals or any software.) It has both 32bit PCI slots and 64bit PCI slots. Is this a 64bit system? Or is it a 32bit system with some 64bit PCI slots? I'm currently using an SMP 32bit kernel with DeMuDi to utilize the full capability of this workstation. Could I be using a 64bit SMP kernel instead? And if so, where would I find such a kernel? Thank you, Stephen.

[linux-audio-user] low fidelity, long duration recording

by Kevin Cosgrove

Hi, I'd like to record about 6-8 hours of one channel, very low fidelity sound. I'll be recording silence, punctuated by sound. It'd be even better if rather than recording that much silence, that the recorder would only record to hard drive when there was sound present. What recording software would be good for either task? Thanks! -- Kevin

[linux-audio-user] How to keep alsa sound card order with usb devices

by John Anderson

At last I figured this out, so I thought I'd share it. My setup is as follows: a terratec ews88mt, a BCF2000, and an evolution eKeys 49 midi keyboard. kernel 2.6.14, Gentoo. The following is a section from my /etc/modules.d/alsa (which ultimately ends up in /etc/modules.conf). The BCF2000 is always card 2 (in /proc/asound/cards) corresponding to /dev/snd/midiC2D0, the keyboard is always card 3 corresponding to /dev/snd/midiC3D0. This remains constant even if they aren't switched on when alsa starts, or if I switch the devices off and on. # 1) ews88mt alias snd-card-0 snd-ice1712 options snd-ice1712 index=0 # 2) virtual midi for softsynth and routing alias snd-card-1 snd-virmidi options snd-virmidi index=1 # 3) bcf2000 alias snd-card-2 snd-usb-audio options snd-usb-audio index=2 vid=0x1397 pid=0x00bc # 4) evolution keyboard alias snd-card-3 snd-usb-audio options snd-usb-audio index=3 vid=0x0a4d pid=0x0090 #Set this to the correct number of cards. options snd cards_limit=4 The key to this is the vid (Vendor id) and pid (product id) parameters for snd-usb-audio. Which in usb-speak are idVendor and idProduct, respectively. The values for these can be found using lsusb -v, which on my system gives the following: Bus 001 Device 011: ID 1397:00bc Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x1397 idProduct 0x00bc bcdDevice 1.00 iManufacturer 1 BEHRINGER iProduct 2 BCF2000 and Bus 001 Device 009: ID 0a4d:0090 Evolution Electronics, Ltd Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0a4d Evolution Electronics, Ltd idProduct 0x0090 bcdDevice 1.22 iManufacturer 1 iProduct 2 I hope someone finds this useful. bye John

[linux-audio-user] m-audio ozone alsa support?

by Lukas Erni

hi there after I've showed some linux audio applications to a friend of my, he wants to build a box running sooperlooper, ardour and some ladspa-plugins. the question is, if the audio-hardware will fit? It is about this usb audio-, midi-combo m-audio ozone http://www.midiman.de/ozone.htm on the m-audio-web-page they say it will run under linux but it is actually not listed on the alsa-soudcard-matrix. can pleas somebody tell me if it is partly (midi/audio) or completely working? since latency is a important issue for a live-tool, what can he expect with usb-audio? thanks for any input lukas

[linux-audio-user] active nearfield monitors

by Greg

Hi list, I'm thinking about getting some decent monitoring for mycomputer. I read good things about Bluesky mediadesk 2.1. $500 orless is what i'm looking at. The Samson ribbon monitors also lookinteresting but bass-lacking. Basically I'm interested in somethingaccurate and flat. I use low end a lot, but I don't like the XTREMEBASS SUBZ you find in most consumer equipment.so what are you using, what for? anything else I should know?

[linux-audio-user] External SB Live USB

by Sean Edwards

Does anybody have the Creative Labs Sound Blaster Live! External USB Sound Card (Model: SB0490) working with Linux/alsa? How is the performance? Was it difficult to install and setup? What audio software do you use with it? I am thinking about getting one. -=cybersean3000=- __________________________________ Yahoo! for Good - Make a difference this year. http://brand.yahoo.com/cybergivingweek2005/

[linux-audio-user] Re: vst: emulate mac instead of win?

by COCHARD Yves

> maybe i am missing something, but i think you're being really twisted > here. running win32/x86 VST plugins on linux/x86 is one thing. but > trying to run win32/x86 VST plugins on */ppc is something entirely > different, > I was missing something, not you! ;-) (my statement wasn't clearly enounced at all). My idea was to run macos/ppc VST plugins on linux/x86. And not that I want to run that, but I thought it could be an easier way to be able to use some vst plugin in linux than running a win32/x86 VST plugin on a linux/x86 system. But as you mention, it is insane... (as a damn simple user without lots of knowlegde about these issues, I thought that linux was "closer" to macos (because unix based) as win.) Thank's for the answers (if I won't be able this idea, I have at least improve my knowledge!). -- "Zwischen Hirn und Händen muss das Herz vermitteln", Metropolis, Fritz Lang.
