I hope you'll forgive me if I ask a *really* basic question. I'm running a mix of Debian stable and testing. Kernel 2.4.18. I have a Creative Ensoniq AudioPCI sound-card. I'm using the OSS kernel drivers, but working up to switching to Alsa. I want to get better audio output---partially just for listening but also because I'm doing more and more recording. I don't do games. So for audio reproduction it's mainly a matter of DVD playing (opera and jazz mostly, some rock). I use Xine for DVD playback; I also use Ogg123 and Xmms for pure audio. So my very basic question is: how necessary or how advisable is it to put an amplifier between the audio output jack and the PC speakers? Has anyone got a recommendation for a good mid-range or mid-price amplifier that would make a noticeable difference? Thanks a lot for your time, Jim

RE: [linux-audio-user] amplifiers

by Lars Åslund

Jim, I´m using a M-Audio card (Audophile 2496) and a LINN Numerik external DAC for Audio playback.(in a ReadHat 7.3 box with ALSA drivers) very nice! It´s very important to have a good source like uncompressed music (or a good compression like flac or someting), good Soundcard, DAC is also very important. If you can get a nice Surround processor you will have a Sdif input, and if you Connect computer from your Digital out to spdif in, you probably get better result. And of cause, ordanary PC speaker is not that fun to listen at... Try to get a pair of used nice speakers, you get more music for less money.

[linux-audio-user] Echo Layla 24

by Christian Schoenebeck

Hi! Has anybody tested the Echo Layla 24? I'm searching for an external audio interface with low latency (for soft synths) and high audio quality (I'm tired of internal cards, buzzing or making stupid sounds when I'm moving the mouse or something) and of course it should support Linux. Layla catched my eye first, because you can also use it in conjunction with a laptop. That's very handy, although not that important. Any pros or contras? Or can anybody recommend another device that matches these criterias? And whatabout DSP functionality? I read a while ago that there are interfaces which come with DSP chips. Is that useful? Or are they supported only by very few programs? Regards, Christian

[linux-audio-user] Free Music licenses: which to choose?

by Graham Percival

I'm finally ready (two months after I thought I'd be) to release some music under a GPL-type music license, but now I'm getting bogged down trying to decide which one to use. Unlike the free software community, which has two highly visible licenses (GPL and BSD), the free music community seems to have a number of licenses, with no clear popular choice. Although most (if not all) Free Music Licenses talk about "help build a common pool of creative expression that can be accessed and improved upon by all of society" (from the EFF's OAL), it's not clear that their licenses allow for that. AFAIK, I cannot combine music licensed under the OAL with music licensed under the Design Science License or Open Content License (except with express permission of the copyright holders, of course). This seems to result in a number of small ponds of artistic expression, rather than one big common pool. Is this a valid concern, or just a wild hypothesis? :) Does anybody have a favourite Free Music License? Right now I'm leaning towards the EFF's OAL, but I really don't like their idea that you should use (O) instead of (c). Two lists of Free Music Licenses: http://www.eff.org/IP/Open_licenses/licenseguide.html http://www.ram.org/ramblings/philosophy/fmp/formal_licenses.html Cheers, - Graham

RE: [linux-audio-user] New software synthesizer for Linux (free under GPL v. 2)

by mprims＠skynet.be

"If you want to use this program to make music that is against God and Jesus (like HeavyMetal, NewAge,..) STOP and think that you'll be judged someday by God Himself for causing many people to loose the Salvation and go to hell. This will happen, no matter if you'll use my program, else's program or anything else against Jesus's name. I wish to know that my work will be used to praise the name of Jesus." Could you be a bit more specific about the genres being against God and Jesus? I wouldn't want to end up in hell. And isn't this in contradiction with the GPL? mik Original Message: ----------------- From: Nasca Paul zynaddsubfx(a)yahoo.com Date: Wed, 25 Sep 2002 01:48:18 -0700 (PDT) To: linux-audio-user(a)music.columbia.edu, linux-audio-dev(a)music.columbia.edu, linux-audio-announce(a)music.columbia.edu Subject: [linux-audio-user] New software synthesizer for Linux (free under GPL v. 2) Hi, I wrote a software syntesizer for Linux, it is available at http://zynaddsubfx.sourceforge.net/ or http://sourceforge.net/projects/zynaddsubfx/ . It has many features including: polipohony, multi-timbral, microtonal capabilities, 2 synth engines, effects (system and insertion), user interface. I started this project on March 2002 and this is the first relase. I hope that you'll like it. Paul. __________________________________________________ Do you Yahoo!?

[linux-audio-user] Linux Laptop Sound article published

by Dave Phillips

Greetings: A while ago I polled this group for information and opinions about setting up sound on laptops running Linux. My article has been published, you can find it here: http://linux.oreillynet.com/pub/a/linux/2002/09/19/linuxlaptop.html Please note that it is rather model-centric, charting my experiences with the HP Omnibook 4150, but hopefully it will inspire other laptop owners who may have difficulty setting up a sound system on their machines. Again, my thanks to all who responded and shared their own experiences with me. As an aside, I must say I've been rather lucky with my 4150, and I had relatively few problems. Someday someone wil have to rate a variety of laptops by their ease of sound setup for Linux. It's evident that some machines and/or chipsets are just not very Linux-friendly, and that information could be very useful for a user looking for a laptop to run Linux audio apps.

[linux-audio-user] (no subject)

by Jago Pearce

The Alsa documentation is confusing me massively. I have no problems getting a basic setup sorted but I'm having trouble when trying to do more than one thing at a time. I have 2 soundcards: - via686 onboard (half-duplex hardware. Can only record OR playback, can only playback one thing at a time atm) - ymfpci (should be full-duplex. Can play back more than one thing at a time. Should be able to record whilst playing back) One way or another I need to record whilst playing back and be able to playback from >1 source (i.e. play 2 mp3 files at once). To do this: - How do I go about setting up /dev/dsp1 as well as /dev/dsp? (I have edited /etc/modules.d/alsa and update-modules to no avail. Can I do this with seporate soundcards or just one? (the ymfpci has 2 channels) - How do I get my yamaha to record whilst playing back (full-duplex)? I have followed install instructions and I think it should work Any links or suggestions would be great. I'm finding Alsa incredibly compilcated for me. Perhaps (as the most simple answer) I could have the via686 using standard OSS and the ymfpci using Alsa? ------------------- details to follow:- ------------------- #lsmod snd-pcm-oss 36804 1 snd-mixer-oss 9184 0 [snd-pcm-oss] joydev 6816 0 (unused) input 3424 0 [joydev] snd-opl3-synth 8604 0 (unused) snd-seq-instr 4432 0 [snd-opl3-synth] snd-seq-midi-emul 4560 0 [snd-opl3-synth] snd-seq 37868 0 [snd-opl3-synth snd-seq-instr snd-seq-midi-emul] snd-ainstr-fm 1540 0 [snd-opl3-synth] ppdev 8292 0 (unused) lp 6176 0 (unused) hid 15072 0 (unused) sr_mod 11864 0 (unused) apm 9608 1 uhci 24296 0 (unused) vfat 10780 0 (unused) fat 32056 0 [vfat] parport_pc 13252 1 parport 14208 1 [ppdev lp parport_pc] printer 7488 0 (unused) scanner 8512 0 (unused) NVdriver 1065920 10 ide-scsi 7680 0 eepro100 17456 1 snd-via686 7076 0 snd-ymfpci 41664 1 snd-pcm 56256 0 [snd-pcm-oss snd-via686 snd-ymfpci] snd-ac97-codec 24432 0 [snd-via686 snd-ymfpci] snd-mpu401-uart 2736 0 [snd-via686 snd-ymfpci] snd-rawmidi 12896 0 [snd-mpu401-uart] snd-opl3-lib 5408 0 [snd-opl3-synth snd-ymfpci] snd-timer 10688 0 [snd-seq snd-pcm snd-opl3-lib] snd-hwdep 3712 0 [snd-opl3-lib] snd-seq-device 3936 0 [snd-opl3-synth snd-seq snd-rawmidi snd-opl3-lib] snd 25928 0 [snd-pcm-oss snd-mixer-oss snd-opl3-synth snd-seq-instr snd-seq snd-via686 snd-ymfpci snd-pcm snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-opl3-lib snd-timer snd-hwdep snd-seq-device] # cat /etc/modules.d/alsa # Alsa 0.9.X kernel modules' configuration file. # $Header: /home/cvsroot/gentoo-x86/media-sound/alsa-driver/files/alsa-modules.conf,v 1.3 2002/06/24 18:05:58 agenkin Exp $ # ALSA portion alias char-major-116 snd # OSS/Free portion alias char-major-14 soundcore ## ## IMPORTANT: ## You need to customise this section for your specific sound card(s) ## and then run `update-modules' command. ## Read alsa-driver's INSTALL file in /usr/share/doc for more info. ## ## ALSA portion alias snd-card-0 snd-ymfpci alias snd-card-1 snd-via686 #alias snd-card-2 snd-ymfpci #alias snd-card-3 snd-via686 #alias snd-card-4 snd-ymfpci #alias snd-card-5 snd-via686 #alias snd-card-6 snd-ymfpci #alias snd-card-7 snd-via686 ## OSS/Free portion ## alias sound-slot-0 snd-card-0 ## alias sound-slot-1 snd-card-1 ## # OSS/Free portion - card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss ## OSS/Free portion - card #2 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-8 snd-seq-oss alias sound-service-1-12 snd-pcm-oss #alias /dev/dsp1 snd-pcm-oss? or something? ...? ----- Thank you for your time.
