[linux-audio-user] Skipping audio output?

by Anthony DiSante

Hello, When I'm running an audio app like XMMS to play music, the sound skips somewhat frequently (maybe 5 times in the course of an album). That's with no load on the system, and nothing using the processor heavily. However if I do something that peaks the CPU (like dragging a window around really fast), this also causes the sound to skip immediately. I recently installed jack and ardour and mean to install the low-latency kernel patches when I get around to it; they are mentioned here: http://www.linuxdj.com/audio/lad/faq.php3 But I'm wondering, is this XMMS audio-skipping problem related to that too? Will intalling the low-latency patches help with that? Thanks, Anthony http://nodivisions.com/

Yeah, and (God I hate to say this) Micro$oft Excel is actually a damn good product. On it's own merits it beats the pants off just about anything else out there.

She's probably receiving Excel spreadsheets from others that already have stuff embedded that won't work with Linux tools. I ran into this problem big time when we looked at Star Office and Open Office for work. We couldn't use either as their compatibility with both Word and Excel wasn't good enough and broke our compatibility with both our vendors and our customers. As someone who runs a business, why would I want to pay someone $600 to fix 10 documents when I can buy Microsoft's tools for $300 and have guaranteed compatibility? That's a tough sell...

[linux-audio-user] License free Linux ??

by Patrick Shirkey

While browsing your site I noticed you are promoting your software as running on a license free Linux OS. You should be aware that Linux software is generally provided under two Licenses. The GNU Public License(GPL) and the Lesser GNU Public License(LGPL). It is a gross misrepresentation of the GPL/LGPL to mislead your customers into thinking they are buying a license free product. In the interests of promoting your goods fairly it is your obligation to inform your customers they are buying into the GNU Public License(GPL). While Linux software is usually free as in beer and speech it is not license free. We are waiting for your action and response. Please be aware that many people read the LAU list which I have included in this post. Some of them even write articles for well known audio publications.

Banking is usually not a problem. There are a few banks that screwed up and went Micro$oft specific but if you load Crossover you'll get Internet Exploder anyway.

Greetings: My thanks to everyone who replied to this subject. Lots of good ideas, I'll definitely put some of them to use. Here a few more notes on what I plan to do : Red Hat (Fedora?) or Mandrake install totally GUI for the user Crossover stuff (thanks for the reminders!) And here's what they have for peripherals : a scanner, not sure what kind an HP printer (610C ? 810C ? I'll find out later... ) Things they need to do include : Web browsing print from Web (color, b&w) on-line banking via Web browser (I'm afraid IE may be required, don't know though) print from file manager (color, b&w) operate scanner basic image editing Their net connection is DSL through SBC/Yahoo. I don't expect problems with that, I had the same connectivity at my old apartment, no problems with various Linux distros. They don't have games installed, they don't really run any apps beyond the browser. My only concern is wrt the on-line banking requirements. Does anyone here do on-line banking via a Linux browser ?

[linux-audio-user] Video card and sound

by Robert Epprecht

There are some issues with video cards and sound: * First of all I want the video card to be quiet! I do not need the fastest and hottest one... * I guess, onboard grafics are problematic, as they don't have separate RAM. Memory operations could be slowed down in applications. Is this true? Are there other sound related issues I should be aware of, when choosing a video card? Robert Epprecht

[linux-audio-user] New tunes.

by Patrick Shirkey

For those into a bit of raw, lofi, hard rock check out some new tracks which were recorded with my Linux powered music machine: http://www.djcj.org/audio/Voipit/ You can read about the machine here: http://www.boosthardware.com/products-mahine.php3 Click on the "rua" link. All the recordings were done with ardour and an hdsp. -- Patrick Shirkey - Boost Hardware Ltd.

[linux-audio-user] voice note recorder

by Helge Hielscher

Hello, hope this is the right list to ask. Does anybody know if there is an audio voice recorder for linux? Like a normal audio recorder, but one that automatically switches between pause and record. The only voice note recorder I found on the web is Windows only and has a huge feature list. http://www.xemico.com/anr/index.html TIA, Helge

[linux-audio-user] Rewrite sfxload for native ALSA

by Mark Constable

You have to load a soundfont with the utility sfxload (available > in the aweutils package). This also implies that you need to setup > OSS-compatibility support in ALSA since the awe utils use that. I anyone aware of ANY non-OSS tool to load soundfonts into an SBlive card ? If not, would anyone be interested in looking in to how to rewrite sfxload so it, at least, uses the native ALSA API ? Even with ALSA in the 2.6 kernel (yay, no more modules) and most apps now converted to ALSA/jack I am still stuck with this small but useful utility. I get around it by simply not using the the soundfont capability of my SBlive. Pity. --markc

[linux-audio-user] Success with midi

by Eduardo Guerrero

Hi, this success story with my midi setup is dedicated to all of you who have helped me these days. I'm finally being able to play with my keyboard the sounds generated by ZynAddSubFX hearing them coming out from the speakers as I play. That's great by itself due to the almost unlimited capabilities of Zyn. Then I got stereo sound which was previously unavailable. Frankly I don't know the reason, but when I upgraded from Mandrake 9.1 to 9.2 panning started to work properly. Then I have Hydrogen. I'm making some good beats with it and playing along with my keyboard. This brings me to my 2 questions: - Is there a way to mix levels of the audio streams going to the alsa_pcm port? I have the possibility of turning up or down the volume in Zyn but it isn't as flexible as it could be since, in this case, Hydrogen doesn't have a volume control (or I haven't figured out where is it). - Can I use some FX on the audio stream? A filter bank, a reverb or a delay line can do wonders to the already-wonderful sound I now have. With audio stream I'm referring to the mixed sounds coming from Zyn and Hydrogen to the alsa_pcm port (labeled as input, but in my point of view it could be the output port --sorry for being selfish here). - Is there a way to share bpm information between apps? For syncing delays it would be great not to have to fire up the delay calculator. I don't have many, if any, programming skills but I guess it would be as simple as using an environment variable. Perhaps the functionality is already there but I haven't found it or nobody uses it. For mixing levels right now I'm thinking that a possible solution could be to program the whole song in Hydrogen and then using it on MusE or Rosegarden but a lower-level mixer (lower in the sense of operating at the alsa level) seems conceptually more interesting. Thank you for the previous help received and for the future comments this post will surely arise. The spirit on this mailing list is beautiful. Eduardo.
