Hi there ...
When watching a DVD one can sometimes select which language to listen
to. I'm looking for a solution where I can playback a movie with two
different languages at the *same* time:
Most of my friends understand english quite well so we want to see a
movie in its original tongue. Just one friend often needs translation
so I would like to be able to listen to german translation with a
headset.
As I do not know of a player that can manage two different languages at
the same time I thought of recording the DVD to harddisk, also record
english and german audio and then mix both audio channels together.
This could either be mixing each language to mono and combine them to
a pseudo stereo containing a different language on the left or right
channel. Or mixing two stereo channels to a pseudo surround sound, one
language at the front the other at the rear.
As written above I do not need to edit (cut or somehow modify) the
streams. All I need is to remix them. Could you please give me a hint,
which tool I can use for that?
TIA
Thomas

Greetings:
As I announced on the LAD/LAU mail lists I will soon put a new edition
of linux-sound.org online. This one will be the last edition for the
foreseeable future. I hope to see the community take over the site and
its maintenance, but for this last publication I have a request for all
developers:
If you have any software listed on http://linux-sound.org please take
a look to see if your preferred URL is listed. If you have software you
would like to see listed there, send me its URL as soon as possible.
Ditto for logos. I'm going through every page on the site, culling dead
links and correcting bad addresses. It takes time, so I'll be putting up
the corrected pages over the next week or so. The latest New Additions
is already up, and I've already corrected some pages (dsp.html took all
day today), but I'll delay an official announcement until all pages have
been emended.
The site will remain online and unmaintained until it's replaced by
something better or I just get tired of looking at it. So, send
corrections, logos, etc. to me directly at dlphillips(a)woh.rr.com if
you'd like your stuff listed so people might actually find it. :)
Best,

Well, probably maybe. Its hard to know what GUI toolkits closed source
software use. And it doesn't matter very much either until there is a
big enough marked for commercial vst plugins on linux, which might never
happen because we have better standards than vst for fitted for linux
audio: The trouble of getting various x toolkits to work with each other
is probably more easely solved by using dssi or just making jack programs
out of the plugins. Besides, ladspa is a much more supported standard than
vst on linux, and for most vst plugins, it probably doesn't require that
much work to make them support ladspa as well as vst.
I think it boils down to vst plugin developers not having much interest
in linux audio. Thats where the work needs to be done I think.
I am quite sure that PureData is the tool you are looking for!
Getting the amplitude value at certain moments and storing them to a
table (storage in pd-speak) is a very easy thing.
Recording could also been done within Pd, in .wav format and then be
encoded by a shell command such as oggenc.
I am not sure howto implement the image (.jpg) display right now, but it
can't be too hard and is possible for sure (using the Pd-addon library Gem)
good luck, post again for more questions if you like!

Hi y'all
I finally managed to get my Intel 965 motherboard (DG965WH) working
nicely - accelerated graphics, talking to all drives. I'm using
2.6.19-rt1 and this patch that I pulled out of the mm tree.
The patch applies to 2.6.19-rt6 as well, but I haven't rebooted to that
yet.
I hope someone finds this useful.
bye

>From 8am-11pm I am recording the audio from a lecture theatre. I want to be
able to programatically and/or visually identify when the lecture theatre is
in use -- the audio feed is silent when not in use. I don't know what tools
could do this. Here are my ideas/desires (the first two are preferable):
-- Every 20 seconds, take a numerical reading of the amplitude level
currently being captured, like a "VU meter" with a "data logger" attached.
(This number would then be saved to a database along with a timestamp and
later processed -- the saving is the easy bit, it's just getting that
number.) I know ecasignalview shows the current level but it requires:
ecasound, ncurses (not possible to automatically grab relevant output so
useless here), and an open audio device (disadvantage).
-- After 11pm, process the audio file and record the amplitude level every
few seconds to a database.
-- Continually save a "spectrum analysis" of the live stream as an image
(eg. JPG) that could be viewed at any time.
-- After 11pm, get a "spectrum analysis" of the whole static file and save
it as an image (eg. JPG). The file is AAC within MP4, but I could convert
it to a compatible format (eg. WAV) with FAAD just for the analysis if
necessary. I don't think this could be done via an X GUI application as it
needs to be automated.
Do you know which application(s) will help in these situations?
Many thanks!

When trying different port options I no longer receive any error messages
before the segfault and everything seems to connect fine. I've found that
using the -jack option with any other option while jack is running is what
causes both './startBristol: line 188: [: too many arguments' and the
program choosing port 0 by default. When running in the non-RT kernel, where
Bristol works as expected, gives './startBristol: line 188: [: too many
arguments' when jack is running and -jack with any other option is used,
though selects the correct default port and works fine. All options I have
tried still result in the segfault on the RT kernel (./startBristol: line
272: 3877 Segmentation fault brighton $*), though, which is the only
real error message left considering that the 'too many arguments' problem
does not effect the working of Bristol on the other kernel.
I use the same software on both kernels and the jack audio interface for low
latency.
p.s. Thank you for Bristol, it's a great joy to play with and it being free
is wonderful.
Thanks,
Glen.

Responding to option 2:
I've terminated the book project, at least my involvement in it is over.
My publisher and the contributors have known this for a few months, I
apologize for not announcing the fact earlier, but as you can see from
my updates to http://linux-sound.org I've not exactly been keeping up.
Various reasons prompted my decision, family concerns being the most
influential.
Re: book structure: As far as I'm concerned, go ahead, use it, it's just
a chapter succession. Lots of new headings should be added anyway.
By the way, I'm fairly certain that all my stuff published by LJ and
O'Reilly still belongs to me. They're pretty decent about it, all rights
revert to the author after a certain period, a nice nod from publishers
towards reusability. Anyway, again as far as I'm concerned the community
can assemble and revise that stuff as it sees fit.
And let's face it, folks, http://linux-sound.org and its mirrors are
doomed. I'm so tired of the maintenance that I'm just not doing any at
all. I'd like to see the community take over the lists and perhaps use
them as bases for a wiki catalog of Linux sound and music software.
Meanwhile I plan for one more update this month, then I'm unlikely to
continue working with it any longer.
I'm sorry but too many other important factors in my life require my
attention now. Writing another book and maintaining linux-sound.org are
unfortunately excluded. I'm not disappearing, I just can't manage those
particular projects.
Best regards,

Hi list.
In my quest for good audio related documentation for the Linux platform, several things
strike me:
1. It is very scattered around the internet.
2. It has no unified structure
3. It is, in some cases, downright ugly. ;)
Don't take this as critisism of webdesigning skills on a community wide basis, I know
most of the people responsible for the websites have better things to do than to put
days or weeks designing their content to please the eye. As everyone knows already,
content is king and webdesign is for sissies. ;)
However, a non-cluttered look and feel should make a newcomer more inclined to find what
they seek, a link-farm of some sort would enable people to delve further into the world of
linux audio and so on and so forth. It seems to me that most places throughout the Linux
audio community are scattered like islands in a very big ocean with nothing to bridge them.
I was thinking about a top row somewhat like the OSTG-bar on slashdot.org and the like,
with maybe 6-10 of the most central sites in the linux audio community. Any rating of
these sites will not be done by me, that's for sure. ;)
The thought was to incorporate this bar on as many sites as possible, with a central link
repository of some kind. How do you feel about such an idea?
I'm willing to implement it, it there's any interest.
Regards,
Mathias
A bit off topic except for the FLAC part. Anyway I thought maybe a
folks would be interested if for no other reason than the technology
they are adopting or maybe doing remixes, etc.
http://www.bnlmusic.com/music/
I caught these guys on NPR this morning. They now have their own
label. They are trusting their customers to do the right thing with
their music. They want folks to spread it around to see if it builds a
market. Granted, the band has been around awhile and has lost most of
it's buzz, but I liked the sound of what I heard.
Cheers,
Mark
