[linux-audio-user] cd burning w/out gaps

by rossen

Hi all... There was a discussion some time ago about burning a CD without the automatic 2 sec gap between the tracks. I didn't really follow it until I needed to do the same thing. Sorry if I'm repeating an old posting but I found that cdrecord has an option, defpregap, that can be used in this case. Just give $cdrecord defpregap=0 -other-options *.wav and it works. The tracks are searchable,and still the mix goes uninteruppted. Unfortunately, the man page says "This option may go away in the future":( -- rossen

Re: [linux-audio-user] Quattro USB (EMI 6|2m)

Actually the card does perform a bit better at 48000. The thing is that at 48000 I get only 6 capture ports at 24-bit - no playback. Suprisinly I got rid of the noise by setting -n 512 -p 4. What I haven't figured out is how to make the EMI capture at 6*24/44100 and playback at 2*16/44100 which would be the maximum performance by this box. In other words how to tell Jack to use certain altset of the playback interface. With the -S switch I get 16-bit input and output but 24-bit capture at least sounds like a nice idea... Any suggestions on how to make that happen? I've tried using pcm slaves from the .asoundrc as Steve Harris suggested earlier but ended up with Segmentation Faults and missing library - notifications only...

RE: [linux-audio-user] Audacity/Windows/Plugins

by Matthew Allen

Ok after about 30 minutes of tweaking, Its non-realtime only, with a preview button. The preview button only gives you about 10 seconds of preview though. I tried it with all of the dfx http://www.smartelectronix.com/~destroyfx/ VST's and the all worked just fine. The lack of realtime operation is a pain. I have only really used Audacity at work to tweak minor things in sound files for our games, so I have never really out it through its paces. m. > -----Original Message----- > From: linux-audio-user-bounces(a)music.columbia.edu [mailto:linux-audio- > user-bounces(a)music.columbia.edu] On Behalf Of Mark Knecht > Sent: Thursday, April 29, 2004 1:43 PM > To: Linux-audio-users > Subject: [linux-audio-user] Audacity/Windows/Plugins > > Hi, > Sorry, but a very non-linux question. > > I wonder if anyone here can say anyting about how the Windows > version of Audacity works?

[linux-audio-user] How to get sound on remote X kde client

by Robert Rozman

Hi, I've managed to get some sort of thin client, but still have some problems. I've enabled XDMCP on my server, and run this on my diskless epia client: "X -query ip_of_server" and I got login screen, got into and could work as just at the server. But I would like to go further. It seems like that desktop is using resources on server (audio, graphic card). How can I get sound from server's desktop to my epia thin client ? I'd really like to get this working cause this will be right device for my kids. In this way they've got TV, entertainment box (running mythtv) and normal PC terminal. Thanks in advance for responses, Regards, Robert.

RE: [linux-audio-user] Audacity/Windows/Plugins

by Matthew Allen

I don't know about the vst stuff, but I have been using audacity here at work for a while (as a cooledit substitute and I have never had it hang or crash (on both XP and win2k pro/server). I will mess with the VST stuff today. m. > -----Original Message----- > From: linux-audio-user-bounces(a)music.columbia.edu [mailto:linux-audio- > user-bounces(a)music.columbia.edu] On Behalf Of Mark Knecht > Sent: Thursday, April 29, 2004 1:43 PM > To: Linux-audio-users > Subject: [linux-audio-user] Audacity/Windows/Plugins > > Hi, > Sorry, but a very non-linux question. > > I wonder if anyone here can say anyting about how the Windows > version of Audacity works?

[linux-audio-user] Linux & sound in swedish

by Andreas Andersson

This one is relevant only for people who understand swedish. Sorry. Jag har skrivit ett 5-poängsarbete om ljud med GNU/Linux (examensarbete på musikhögskolan i Örebro). Om någon är intresserad av att läsa det så kan jag maila det i pdf- eller openoffice-format, alternativt posta en papperskopia mot ersättning för porto och kopiering. (Den digitala versionen saknar försättsblad. Tycker man att det är viktigt bör man välja pappersversionen...)

[linux-audio-user] Is there no way to split L+R channels for ALSA applications?

by Malcolm Baldridge

I'm a bit surprised noone knows of a way to specify just one channel of a given output device, i.e., just the LEFT channel or the RIGHT channel of the main PCM output device. The asoundrc syntax documentation is extremely lightweight in this regard. The closest thing I've seen is an example showing how to bind two stereo output devices into a single 4-channel output device using "bindings" directives. I'd appreciate any pointers. Thank you, =MB= -- A focus on Quality.

[linux-audio-user] Digital distribution (was RE: Audigy 2 ZS Platinum Pro)

I tried xine and alsaplayer but neither was happy with the > very Windows-ish format. Yeah, it's a bit of a pain, but it's a good way at the moment of distributing songs without the hassle of posting CDs and handling payment. Bearing in mind that most people still use Windows it's the lesser of two evils to put songs out using DRM encoded WMAs. At least a large percentage of my audience can listen to the tracks in full before committing to purchase. Older tracks are available via Vitaminic and Soundclick, but I found I was spending more money promoting them than I was getting back. Links to those sites are below if Linux people want to check out some of my older material (plug! plug!) Anyway, Audigy2? External connectors? Anyone? Bueller? cheers daniel http://www.onionjack.com | http://www.soundclick.com/onionjack | http://stage.vitaminic.co.uk/onion_jack <http://www.stage.vitaminic.co.uk/onion_jack>
