[linux-audio-dev] Voice playback with varying speed and same pitch

by Mario Lang

Hi. I am currently trying to write a player for the DAISY 2 and 3 Digital Talking Book formats for UNIX machines. One of the big great features of the hardware DAISY players available is to set ones own prefers playback speed while retaining the original pitch of the voice. This only works within a certain percentage of variation of course, but it does actually help a lot if you're used to fast speech. I am wondering if there are any existing libraries/command-line tools to do this. DAISY uses mp3 as its main audio format, so it would help if this tool could do it with mp3 directly, but I can probably integrate other solutions too. Any suggestions would be appreciated. Note that I do not really need an algorithm that works well with music in general, it only has to work well with the typical spectrum of a human voice. -- CYa, Mario | Debian Developer <URL:http://debian.org/> | Get my public key via finger mlang(a)db.debian.org | 1024D/7FC1A0854909BCCDBE6C102DDFFC022A6B113E44

[linux-audio-dev] OpenJay Development Krew [OJDK]

by J_Zar

Finally, I would like to introduce the OpenJay Development Krew [OJDK], which actually is only a mailing list with little mail-traffic. The OJDK is the right place for OSS Dj oriented software developers: here you should find the right audience for discussing, sharing and improving code, take / give suggestions and similar. The OSS software is actually a powerful alternative (and with always greater occurrence a refferral point) in many fields. Although it is not the djing OSS case. There are many reasons for that: little OSS compatible hardware, few and small projects... few users... The closed ring of open dj software is based upon few users and few developers. Crashing it is my intention. To do that my efforts are enclosed in three projects (enough to cover the whole issue) : - OpenJay.org : the user side of the opensource dj world ; - OpenJay Development Krew [OJDK] : the developer side of the opensource dj world ; - Jay'O'Rama : my personal software solution which I'm developing since 1 year and that will be only an alternative ; You should think to OJDK not as a project factory, but mainly as an improving factor for code and a discussing place. Projects will come if needed and desired. Please...if you are an interested developer, CATCH THE OPPORTUNITY, join the OJDK list and mail it! More than money or hardware, I need more than ever some community help in these directions... There are already some project developers joined our little community.

[linux-audio-dev] minor updates to Linux soundapps site

by Dave Phillips

Greetings: I've made some minor updates and URL corrections for the Linux soundapps site, but I've also discovered a problem with the European mirror. The site at www.linuxsound.at now presents an advertisement for ATNET, and the advert includes a link to http://linuxsound.atnet.at. Alas, that link doesn't work correctly either. I've written to ATNET twice already and have heard nothing from them. If the problem persists for another week I'll remove that link. The Japanese mirror is also experiencing a problem: apparently it isn't updating the top and TOC pages, which is uncool because I've added material to both those parts. Hopefully the Japanese mirror will update completely by this weekend. For the time, the only completely current site for the Linux soundapps pages is now: http://linux-sound.org And you all know the rest... Best regards, dp

[linux-audio-dev] [ANN] JJack 0.1 - Java for JACK initial release

by Jens Gulden

Hello, JJack 0.1 - Java bridge API for JACK has initially been released. http://jjack.berlios.de/ JJack is a framework for the Java programming language that allows creating and running portable audio processor clients for the JACK Audio Connection Kit. There are 3 alternative ways to run JJack clients: - using the JJack shell application - as JavaBeans - as standalone application Please let me know if you have created a Java audio application with JJack, it can be made available for download on the JJack site if you like. If someone knows how to compile the native bridge library libjjack.c for other OSs than Linux, please send the resulting binary to me. Co-developers are always welcome. Make noise. Jens

[linux-audio-dev] kernel preemption patch and 2.4.19

by Michael Ost

What specific benefits have folks seen by turning on the kernel preemption patch in a 2.4.19 kernel? We found that a nasty system crash was fixed by turning off preemption. The crash would happen fairly reliably by switching between virtual terminals a number of times. It locked up the system hard. So hard that we can't really find the problem in the kernel; we just found a work-around basically by trial and error. We turned on kernel preemption basically because "everyone was doing it". We haven't noticed any obvious, serious problems or differences since turning preemption off. Does anyone have some suggestions about what differences to expect and what we might have a closer look at? Also, we are newbies about reporting this kind of crash. Any clues about where to report it or ask about it? Thanks for any help... mo =================================== Michael Ost, Software Architect Muse Research, Inc. most(a)museresearch.com

[linux-audio-dev] Latencytest of filesystems (ext2, ext3 w. defaults)

by Roger Larsson

Result looks OK with a SuSE kernel (I think they have lowlatency patch applied), worst was ext2 - it was diskread that had most problems... ext3 - diskread (!?) diskrm included for reference http://w1.910.telia.com/~u91005836/index.html [I have to recheck the results when I am awake :-] Patches are attached - with extras (see below). Hmm... the output should really add kernel version: uname -r "2.4.21-215-athlon" Close, but does not tell that it is precompiled by SuSE X11 server and filesystem type: how to find that automatically? I use, XFree86 nv Extras: * some filehandling (non local root of testing) and * run with min(SCHED_FIFO)+1 not max - it is a CPU hog (80%) [the more CPU usage the less prio] - show that it works to avoid creating a trend... /RogerL -- Roger Larsson Skellefteå Sweden
