Hi everybody,
Fallowing up the long discussion i'm trying to sort of give the
information you all seem to be missing.
there was a meantion of this, but not too many of you have paid any
attention:
here you can find an article about the current status of the protocol mess:
http://prosoundnewseurope.com/pdf/PSNLive/PSNLive_2009.pdf (page 28)
obviously eas50 is good to go, but Ethernet AVB is right thing really.
the only thing that it's still work in progress, but many of the
proprietary vendors, which already have their own networking solution
(like Harman with HiQ-net, the one i can name of top of my head)
are involved in AVB stadard deveelopment.
The idea of AVB is to bypass the IP layer, which is right thing really.
you don't need to assign IPs to your audio nodes, really!
in avb you'd just have to select channels that nodes whant to listen to.
there is a fair bit of documentation on the ietf.org AVB group's page.
but XMOS is looking to be the best point of refference:
http://www.xmos.com/news/15-jun-2009/xmos-simplifies-ethernet-avb-implement…
is think we should forget everything else and crack on with the XS1 AVB
implementation!
their XS1 chips seem to be really great,
their are basically every innovative and open-source minded.
the official toolchain is LLVM-GCC based.
you can use C, C++ or their own XC.
XC is basically C with some stuff omited (like goto and floats)
and XMOS IO stuff added, don't just say WTF, look at it first!
you should also watch the videos here:
http://www.xmoslinkers.org/conference-online-wf
especialy the two about the "XMOS Architecture" and the AVB
presentation.
some dev-kits are quite expencive, but that's due to low-volume really
;)
there is alos a nice USB Audio kit!
plus there is alittle board that is cheap and has two RJ45's on it
already :)
I'm myself studying the XC book at the moment. And geting familiar with
the tool set :)~~
looks very exciting, cause these are the invovative chips!
ok, may be an FPU is really missing on XCore, but how many DSPs have
it anyway? well quite a few, but there was no FPU on dsps for ages! :))
also XC or C/C++ are so much more obvious then the bloody "menthal american military engeneers non-sense" called HDL-whatever!
Cheers Everyone,
Hope you will appreciate my excitment :)~ (l0l)

hi...
i am working on a c++0x DSP library.
variadic templates prove to be a nice way to handle
the massive function inlining required to build efficient samplebased
processing graphs.
the idioms i am currently using for the containers require gcc-4.5
though, so this is still a bit of a show-stopper :)
its still in a pretty early state. but you can already see where its
heading.

Dear Linux Audio developer, user, composer, musician, philosopher
and anyone else interested, you are invited to the...
Linux Audio Conference 2010
The conference about Open Source Software for music and audio
May 1-4 2010
Hogeschool voor de Kunsten Utrecht (HKU)
Utrecht, The Netherlands
Registration is open, and so is the call for abstracts and papers.
More information can be found on the website:
http://lac.linuxaudio.org/2010
For previous editions, look here:
http://lac.linuxaudio.org
For concerts, music and workshops a submission system and protocol will
be available soon. In the meantime, ideas and announcements can be sent by
e-mail ("lac -at- linuxaudio -dot- org ")
or written on the wiki:
http://wiki.linuxaudio.org/lac2010
We hope to see you all in Utrecht !
Kind regards on behalf of the LAC team,
Marc Groenewegen, lecturer music software design @ HKU
Hi, for the timebeing mp3 support is broken is sndfile doesn't actually
support it. You'll have to use wav files.
What do you mean by "It won't connect to Jack"? You dont see the
Terminator outputin qjackctl? Or you cant connect them?
Check the prefs if you've enabled Jack as the output.

Hi to all!
First post to this list :) and I will use it to present small project
I've been working on.
VocProc is a real time JACK application for vocal processing including
pitch shifting, automatic pitch correction and vocoder.
It is basically the same thing as fons' jretune or Tom's autotalent. I
wanted that functionality but at that time fons didn't made it and I
wasn't aware of autotalent. So I made it myself and decided to release
it. I have not tried any of the above for now, so I cannot say
anything about sound quality differences.
I made a working version of VocProc some time ago, but now finally
found some time to clean the code and prepare it to be released.
You can grab the code at:
http://hyperglitch.com/dev/VocProc
Currently, code was only tested and compiled on my computer (Arch
Linux, fftw-3.2.2, Qt4.5) and it works OK (for me).
Any feedback and bug reports are appreciated.
Cheers!
Igor
Dear fellow LA* members,
As some of you may be aware, instead of a static news page, Linuxaudio.org now has a direct LAA feed as its front page. Consequently, I would like to encourage everyone to please put special care in crafting your LAA posts, meaning much more so than those destined for lau/lad lists, as this is in part what everyone sees when they visit Linuxaudio.org (and if our awstats are any indication < http://stats.linuxaudio.org/cgi-bin/awstats.pl?config=www.linuxaudio.org>, then we do get tons of exposure there that is perhaps more importantly steadily growing). I say this not because there have been some grave offenses recently but rather because I think as a community it would really nice if we collectively put extra attention to this facet that is much considerably "public" than a typical lau/lad post. So, I guess what I am trying to say is perhaps having a post on lau/lad lists mirrored on laa may not be always a good idea.
If I had to single-out one post in there that could use some TLC :-) it would be the call for submissions for the upcoming LAC. Namely, suggesting that there has been little interest may end-up looking like a self-fulfilling prophecy--new and incoming potential contributors to LAC who may have come across this post could be easily discouraged by the way this reads despite the fact we all know that most conference submissions are usually uploaded in the last 72 hours before the submission deadline.
At any rate, don't mean to be preaching, so I hope no one will get offended. And if you do, I guess I owe you a pint (hear that Frank? ;-)
Just my 5-cents worth...

Hi,
Has anyone tested TerminatorX 3.83pre?
Gerald
>Hi guys, I'm proud to announce Terminator 3.83pre for testing
(http://www.set-germany.org/TerminatorX/terminatorX-3.83pre.tar.gz).
>Changes: support for rubberband, filehandling exclusively through
sndfile, some bugs fixed and i hope none introduced :)
>Rubberband is used for timestretching the samples. Each turntable has
now an extra 'tempo' knob to stretch/shrink the sample without change of
pitch. >Furthermore a tempo sync option was introduced to sync clients
tempo to that of the master: Select a master -> Select one or more
clients -> Press >play (load some samples before ) and turn the master
tempo knob and note the automatic change of the tempo of the clients.
>Note that the tempo is actually just the stretch factor of the entire
sample since the samples aren't analized for their transients (that's
the next feature!).
>To simplify the code, i decided to rely totaly on sndfile
(http://www.mega-nerd.com/libsndfile/). That means only the formats
understood by sndfile are >supported.
>I tried to contact Alexander König, but he hasn't answered. Maybe we
should pull up a sourceforge project?
>Looking foreward to answers, ideas and complaints.

Greetings,
A respondent to my latest article for LJ has asked if I can recommend an
audio function generator for Linux. He's using a command-line app now,
but he'd like to know if there's such an app with a GUI.
Any suggestions ?
Best,
dp
