Re: [LAU] L_ProAudio: A Linux Proaudio FrameWork with improved Wine/kernel(rt) support [Jordan]

And what about prop. drivers and the kernel? >Nvidia etc -- they are plague but on some machines they are needed.... Yup, rt-kernel with some extra options/patches for those who might want them. Any software that i have tested with this version of Wine (beyond audio stuff) seems to work fine. Other programs aren't using the L_ variables / RT stuff anyway, so their shouldn't be an issue with them. that being said, i'm not really interested in transgaming, using MsOffice in wine or anything like that, i mainly use VST/ASIO stuff... so you may be a better judge, if you happen to be running non-audio stuff. Nvidia should work fine - since i am a long-time Nvidia user (and I am using the latest 313.09 with rt / L_pa), that is a must have for me. I had hoped to fix my nvidia package over the weekend, but i had some important / work-related stuff come up, so hopefully later this week i can sit down and properly package it, but it probably won't be until the weekend. (2013 so far, has been extremely busy at work for me). I've got a small Wiki up too (now) that might answer a few of your other questions, i'll be adding some more stuff, (again) once i can free up some time (soon). Jordan

About Digital I/O

by Gabriel

Hey everyone !! I have a question here about my usb audio interface. For reference it is a UA 55 Quad Capture. But I'm specifically asking about the digital input it has. How can I use that digital input ( COAXIAL ) ? Can I "expand" my audio interface with two more channels coming from another usb interface or any outboard gear, and if that is doable, how can I do it ? And the outputs, what are they good for ? How can I use them to improve my recording workspace and gear ?

Library for simple audio programming

by Ivan K

I want to write a simple application that can open a .wav file (stereo or mono), grab the header, and then read and dump the sample values from a portion of the .wav file to an ascii data file (I want to plot minute portions of the sound file with application such as gnuplot). I am most comfortable working in C, though I would consider working in C++. What library or libraries do people suggest I work with? Thanks. P.S. Or maybe someone can suggest a command line utility that already does this.

L_ProAudio: A Linux Proaudio FrameWork with improved Wine/kernel(rt) support

by jordan

Hi, I tried to announce on the announce list - but no dice. I am subbed, have been for a long time. still fails...oh well. I've been working on a fun and worthwhile project and would like a broader testing audience. (dog-fooding, testing, feedback). So far a few people are aware here and there, but i thought i would share here too; L_ProAudio: consists of 2 main components; 1. L_pa-kernel: 3.6.11-rt25 with additional _bunch_ of patches. It is a high-performance RT kernel setup _specifically_ for proaudio *and* Wine(not upstream). It contains patches from Bao Mao, Muse Research, and others. I have it tweaked nicely. it not packaged specifically for xyz distro, although for archlinux, 2. L_pa-Wine: this is a highly multi-threaded version of wine that deprecates wine-rt patch. It handles multi-threading for wine VST/ASIO like a beast. It is my re-implementation of Muse Receptor GPL'd Wine Patchset :) ... I've also tweaked wine a bit by patching it to add the abiliaty to map your Windows 'desktop' color to menu lines (it's usually hard-coded to something, so you are stuck). This allows easier theming (screenshot @ sf.net). there are many bug fixes, vast improvements in most areas. note: it doesn't magically make _all_ vsts run. but you should see great improvements: new env variables (to enable new model); env L_RT_THREADS=1 L_ENABLE_PIPE_SYNC_FOR_APP=1 foo anyway, i won't be much help for your 'distro-specific' help, but i am certain, people whom have a little skill if they run into minor problems, don't mind dogfooding a little for _great_ bountry, will enjoy this one. NOTE: this is a two part system. Wine is tailared for linux, linux is tailered for wine and native proaudio (i've been using/building this code for a while and re-based onto upstream -rt and wine 1.5.20, as well as solved a reasonable latency/bottleneck issue - that makes me want to release and start this project. I'll be setting up a wiki shortly, with more information feel free to contact me - and please run both, provide feedback, patches, etc. Jordan Ps: Enjoy.

[OT] Anyone attending FUDCon?

by Charles Henry

While it's not a specific conference for Linux audio, I thought some of you might attend the Fedora conference in Lawrence, KS this weekend. I will be here in Lawrence (my home, I'm not directly related to the conference) and I will attend some of the papers and workshops. I'd be happy to meet anyone who's working on Linux audio projects and talk about computing. Chuck

More from the archives - The Radioplayer

by Julien Claassen

Hello evferyone! Being busy housekeeping, I also want to release this collection, even larger than the previous one. It contains themes and incidental music to radioplays - both used and unused -, jingles for the LAC (2005-2007) - also used and unused - and a small audiobook (in German I'm afraid. So forgive me for this: Ihr Deutschen und Deutschsprachigen: Es gibt Horror aus dem Hause Claassen. Ich bin nicht ganz Stolz darauf, aber ein bisschen. :-) what else is there than giving you: http://juliencoder.de/nama/radioplayer/ And mention - as always - that feedback, as long as it is kind and/or productive, is highly welcome. :-) Warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html

Free sample collection online

by Julien Claassen

Hello everyone! this is not really Linux-Audio since only four of these sounds were directly recorded into a Linux box. The rest was recorded with a Zoom H4N. First her's the link: http://juliencoder.de/samples the samples are provided under the terms of the Creative Commsn Attribution Non-Commercial license, just like those of freesound.org. Still, I'd be very grateful, if someone would drop me a link, when they use them, because I'm a curious bugger. :-) These are samples of bird songs, me walking through the village, walking staircases up and down, crossing corridors, the morning routine in the bathroom, a visit to the boiler room... They should be usable as background sounds in radioplays or movies or whatever. They are not edited in any way, so you will always have to cut the beginning and the end. Otherwise, it's stereo (mostly with the H4N buil-tin microphone twisted to a 120 degree angle), all that in CD quality. If you need something, there are flac files here. Enjoy and spread if you like. - As ever feedback is still welcome. Warmly yours Julien ---------------------------------------- http://juliencoder.de/nama/music.html
