It isn't detaild sufficiently. Say, if I have a signal with 10 tones at -20db 
level (in 20Hz - 20KHz range), I'd want to see 10 appropriate peaks at -20db 
with almost -inf db between (and harmonics and intermodulations at case this 
signal is was going and recorded through some hardware - all chain must work 
at 192K).

Hi,

Since you have an audio file, Sonic Visualizer is ideal for this:

Have you tried Audacity? Choose Analyze->Plot Spectrum and you probably 
get all the options you need.

[LAD] detailed spectrum for wide freq range

Andrew Gaydenko — 2010-03-12T06:26:50

Hi!

I have an audio file (say, ~10 seconds) and want to see detailed spectrum at 
wide range (say, from 10Hz up to Fs/2). There is excellent FA's jaaa analyzer 
(and I use it at constant base), but it has linear freq axis, while log scale 
is more appropriate at the case. Off-line (not real-time) analysis (with as 
well as possible quality) would be appropriate.

Suggestions?

this looks good, and will work.
you needs to set JACK_PROMISCUOUS_SERVER for all clients also.

Hello Gerald!
   I try to download your album via torrent (OGG) and it seems there's no peer. 
I started it this morning and then had to go out, still nothing going.
   Which alternative should I choose to download?
   Kindest regards
             Julien

Hi Guys,
At last I've managed to put my music online. 
Check out http://www.jamendo.com/de/album/62900.
'Let it go' is my first Linux only production, and now I have fully

Please send me your impressions.

[LAD] [ANN] QjackCtl 0.3.6 - Full D-Busification!

Rui Nuno Capela — 2010-03-09T20:45:35

Awe!

Times they are a-changing although Bob Dylan has no D-Business here. The
old and cutie gooey for JACK just got one turn around the verge of
bit-rotting. This time it brings full JACK D-Bus support, or almost. It
also adds D-Bus access for most GUI actions which some might find pretty
handy for keyboard shortcut binding from your desktop environment of
choice. However, if babies health is your top concern you can just turn
this D-Bus thing off and play with the old times ;) Ahem...

  QjackCtl 0.3.6 is now released!

Re: [LAD] [LAU] Descent synth as dssi

Paul Davis — 2010-03-09T20:13:43

it doesn't change anything about how applications save state. it
merely provides for a unified way to initiate a save, and a unified
way to restart everything back in the same state (or as close as each
individual application will allow.

Re: [LAD] [LAU] Descent synth as dssi

Julius Smith — 2010-03-09T19:43:40

2010/3/9 Burkhard Wölfel <versuchsanstalt-Mmb7MZpHnFY< at >public.gmane.org>:

Since I always use shell scripts to get as close as I can to a
particular set-up state, I would love to see more support for that, to
the point that it doesn't have to look like scripting to an end user.
For example, each app could respond to a message to return its state
in shell-script form, like a ~/.jackdrc file, and the session saver
would simply append these to a startup script that it can run behind
the scenes to restore the session.  Of course,  active connections
among apps need to be uniquely identified in some way (OSC?), and apps
should be able to accept connection specifications that are not
immediately "ready", etc., so that the segments can be run in any
order.

How would you share a complicated production setup, aka session, with  
other users? Script, or text explanation? Screenshot? Ardour audio  
project only?

I'd love to have a rather bullet proof way to make my sessions  
available to non-geek collaborators really fast and easy. And vice  
versa.


Software trying to outsmart the user can be painful. On the other  
hand, there are users out there waiting to hop on the linux audio boat  
as soon as there is an obvious way to save and restore complex setups  
without scripting. I'd love to make music with them.

It's good that you are happy with your way of using your DAW and so am  
I. But it makes me a little sad sometimes that for remote  
collaborators the learning curve is so steep.

[LAD] [ANN] Drumstick libs 0.3.0 released

Pedro Lopez-Cabanillas — 2010-03-09T15:54:13

Drumstick is a C++ wrapper around the ALSA library sequencer interface using 
Qt4 objects, idioms and style. ALSA sequencer provides software support for 
MIDI technology on Linux. Complementary classes for SMF and WRK file 
processing are also included. This library is used in KMetronome, KMidimon 
and KMid2, and was formerly known as "aseqmm".

Changes:
* Split into two libs: drumstick-alsa and drumstick-file
* Parse Cakewalk WRK files included in drumstick-file
* Some fixes and API additions. See the ChangeLog for details.

Re: [LAD] jack daemon scripts

Ray Rashif — 2010-03-09T00:18:12

I'd say they're indirectly related.

The primary feature request in this case would be:

"Allow mulitple users to start/run/access jackd, and allow multiple
client connections from these users."

And if that works, naturally an init script will work too. Or rather,
an init script will only work if the above is implemented.

Anyway, as far as the thread subject is concerned, the init scripts
have been removed from the package until the feature is supported
upstream: http://bugs.archlinux.org/task/15102

Re: [LAD] jack daemon scripts

Ray Rashif — 2010-03-09T05:02:13

It looks like the promiscuous part of the code hasn't changed:
http://trac.jackaudio.org/changeset/1028

So it should still work, but for some reason connections aren't
getting through, although jackd is setting the correct permissions for
/dev/shm/$jacktmpdir..a test case I ran by creating a normal user
"audio":

[root< at >localhost ~] # useradd -N -K SYS_UID_MAX=499 -K SYS_GID_MAX=499
-s /bin/bash -g audio -G users,video,network -c audio -d /var/lib/jack
audio

[root< at >localhost ~] # mkdir -p /var/lib/jack && chown audio:audio /var/lib/jack

[root< at >localhost ~] # su - audio -c 'umask 0000 && export
JACK_PROMISCUOUS_SERVER && jack -P55 -dalsa -dhw:0 -r48000 -p512 -n3'
*** server start success ***

[root< at >localhost ~] $ ls -l /dev/shm
total 0
drwx------ 3 audio audio 60 Mar  9 12:35 jack-1001

Perms are not correct, so try again with JACK_PROMISCUOUS_SERVER="":

[root< at >localhost ~] # killall jackd && su - audio -c 'umask 0000 &&
export JACK_PROMISCUOUS_SERVER="" && jack -P55 -dalsa -dhw:0 -r48000

[LAD] [ANN] QmidiCtl, QmidiNet 0.0.1 - New Kids On the Block

Rui Nuno Capela — 2010-03-09T08:12:56

Greetings,

QmidiCtl [1] is a MIDI remote controller application that sends MIDI data
over the network, using UDP/IP multi-cast. It has been designed primarily
for the Maemo [3] enabled handheld devices, namely the Nokia N900 [4]. In
its current development state, which is obviously alpha as of this
writing,
it puts a mini multi-track recording control surface on your hands and
on-the-go, so to speak. MMC is the feature and yours truly Qtractor [5]
the
target. However, any other MMC enabled DAW may be considered.

However nothing of this would be possible without this little thing that
gets also here its release announcement: QmidiNet [2] is a MIDI network
gateway application that sends and receives MIDI data (ALSA Sequencer)
over
the network, using UDP/IP multi-cast. Fundamentally inspired by
multimidicast [6] and designed to be compatible with ipMIDI [7] for
Windows, it's a little tiny application that sits as an icon on your
system
tray and exposes one or more ALSA Sequencer client ports which open the
