Hi everyone,
I realise this is not strictly linux audio related, but I guessed that
the most likely people to be able to answer this would be on this
list.
I am wanting to get some audio and video recorded - sample accurately
- so there is minimal delay between audio and video, and no drift. Can
any format do this? Do you have recommendations about how to record a
file which will play back with perfect audio and video sync on all
players (file size is not an issue)?
Secondly, I am wanting to intentionally shift the audio timing so it
may be 5ms/10ms/50ms/100ms or more out of time with the video. Do you
have any suggestions on software which will do this?
Lastly, do any of you know any research about the limits of human
perception with these kinds of things?
Best wishes
James

I posted this weekend, page synthesizes sounds using three factors in the Qt
version.

reminder lm3jo :
Project synthesizer sounds lm3jo
The lm3jo synthesizer can play and create new sounds. It is a free download
for use with Linux. Lm3jo can be used as well by using the QWERTY keyboard,
the mouse , or plain text files . Lm3jo also allows you to mix up to 16
audio tracks.
Lm3jo was written using three basic principles innovative , one in
mathematics, one acoustic and one in the form of association of ideas,
while using a lightweight audio format I created it a few years ago .
Sound database contains thousands of files , built using spreadsheets. The
synthesizer uses the audio abadie.jo in its form of 2 bytes per wavefront
format. But useful three basic factors that can reconstruct all the sounds
in its creation part .
The synthesizer is primarily intended for children to play with the
keyboard playing several instruments .
It is also intended for musicians who are looking for new sounds.
And for the explorers to observe what I call the hammer transform his
guitar piano sound by increasing the length of the edges of the hammer.
I used to find my names :
The hammer , a large amplitude that decreases progressively increasing the
duration of the wavefront
As an example :
http://commons.wikimedia.org/wiki/File:De_la_caisse_au_piano.ogg
Marriage, different forms of association amplitude
The unicorn is a form of low amplitude crete example that allows me to surf
the consonants on vowels without the mixer
The dressings, it is the combination of the previous three definitions
associated with forms of variation of times .

lm3jo is writing on a proprietary audio format that limits its use Linux .

I recently purchased a Zoom H6, and today tried it out for the first time
on Linux. With a clean install of UbuntuStudio 13.10 (Just released this
morning), I found that it is recognized as an audio interface in two-track
mode, but in multitrack mode, Jack won't start, complaining that it can't
acquire hw:H6 or hw:1 or hw:(1,0), I tried them all.
Any word on an ALSA driver for multitrack mode?
...just as a reference point, the H6 was plug-n-play on a mac with
pro-tools 10 in multitrack mode. The manual also claims Windows support,
but with a manually-installed driver.

...I live in the hope that one day the fine line of distinction between
genius and insanity will be decided in my favor.
Is there a simpler way in Ardour to put different plugins on one side of
a stereo field than what is on the other side, than to split into to two
mono tracks/buses with their own completely separate channel strips?
I'm assuming there probably isn't, and if so, that's ok...just
wondering.

I'm happy to announce the second (v0.2) release of Linux Show Player!
Linux Show Player (LiSP) is a sound player specifically designed for
stage productions.
*I need developers / tester / helper to help me in the project (much
needed), I'm open to any suggestion that can improve it, but I can not
do it all alone* ;-)
New (major) Features:
Step based programming;
Reversible actions (do/undo operations);
MIDI remote control.
Plan for next release:
Better audio management (with output device selection);
New (timeline) gui for time-based programming;
Better standalone theme (if someone help me);
Any other.
Linux Show Player is available at:
http://code.google.com/p/linux-show-player/
Please report bugs using the issue tracker:
http://code.google.com/p/linux-show-player/issues/list
Sorry if this is an obvious question, but I'm short of time today and
really tired of Google searching.
I'm running:
Linux dlm-A6200 3.2.0-54-lowlatency #56-Ubuntu SMP PREEMPT Thu Sep 19
17:22:47 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
I have jack 2 connected via ALSA to an M-Audio Fast Track Pro.
If there is any slight glitch in the USB power -- for instance, in a
performance space where the sound engineer might need to plug/unplug cables
frequently -- jackd spins out of control on one CPU and often locks up the
user interface, forcing a hard shutdown and reboot. If I'm very lucky, I
can get into the terminal, find jack's PID and kill it, but when the mouse
and keyboard stop responding, there's nothing I can do reach for the power
button.
This occurs less frequently in 12.04 than it did when I started with 10.04,
but when it does happen (as it did just now), it really, really ticks me
off.
I think there must be some automated way for the system to recognize that
jack is out of control and kill it. [1] notes:
-t, --timeout int
Set client timeout limit in milliseconds. The default is
500
msec. In realtime mode the client timeout must be smaller
than
the watchdog timeout (5000 msec).
Interesting... "watchdog timeout"... but I have never seen any effect from
the watchdog mentioned here. Jack just keeps locking up the system for way
longer than 5 seconds.
I'm happy to provide more info if you can tell me what commands to run.
Normally I would research it myself, but I'm just not in the mood today. If
there's already good documentation on this, great, but... too many pages to
read and I have no idea which is the best one.
Thanks,
hjh

Dear list,
is this computer a good choice for linux+audio+GFX?
Lenovo ThinkPad E531 68851B3
intel i7-3632QM Ivy Bridge processor, NVIDIA GeForce GT 740M 2GB GFX Card.
thx,
m.
Sorry Ralf... I hit the wrong button :(
Have a good week all!

Agreed Ralf.
I run a similar setup, but it's not laptop. Same processor, but graphix is
Nvidia GeForce GT770 4Gb...
No problem at all. I can record and playback with the build-in audio card.
I did have to install the ethernet drivers manually for the motherboard.
Which took me some time to figure out (not so experienced) It's an MSI
motherboard.
Like i said, i'm no pro...just sharing my personal experience
Best of luck!
maybe i should add, that i run ubunustudio 13.04 on it....

Hi, after writing to falkTX, problem resolved.
I had changed audio driver from JACK to JACK with ALSA MIDI, but I did't
noticedm that it cjanged the item below: Process mode - to continuous rack.
The solution is change process mode to MULTIPLE CLIENTS.
have a nice day.

Hi,the new version of carla doesnt show correctly the ins & outs of plugins
in
the patchbay. Also in patchage they aren't, so i think the new carla is not
creating good jack conections... or ?
thanks
fero
