CHANGES 0.3.1 -> 0.9.0:
-----------------------
* Removed timer process testing. This was only a problem with older 2.6
kernels. (think it was fixed early 2006 or thereabout). No scary
messages printed to the screen anymore.
* Tested on Fedora core 10.
* Cleaned up documentation a bit and added instructions for installing on
Fedora, Gentoo and Debian.
This patch adds selection logic to ALSA timer initialization, trying to find
the best available ALSA timer (a non slave timer with lowest resolution).
Currently muse uses only the ALSA system timer, even when the system has an
ALSA RTC or ALSA HPET drivers available, which are probably better for many
users.
This patch applies to muse CVS REL07 branch, dated 20090214 (post 1.0rc1
release).

Hello all,
Trying to control a cluster of computers from the
only 'headed' one I've run into two unexpected
problems. Any thoughts or suggestions are welcome.
(all the ssh in the examples below use dsa keys
to authenticate without a password, logins are
always OK)
The first is this:
Open an xterm and do
ssh -X remotemachine
. ~/.jackdrc
This runs jackd on the remote machine, and
a Ctl-C in the local terminal stops it.
All OK.
But then
ssh -X remotemachine ". ~/.jackdrc"
runs jackd as expected and its output appears
in the local xterm. But a Ctl-C in the local
xterm does terminate the ssh connection but
not the remote jackd. Why not ? It's not
backgrounded.
The second is this:
Open an xterm and execute scriptA which
contains a line like
ssh -X remotemachine scriptB
This runs scriptB on the remote machine. The
script contains 'make' commands, one of which
is 'sudo make install'.
The produces an error from sudo, complaining
there is no terminal. But surely there is one,
even if it is via an ssh connection.
Replacing the line in script A with
ssh -X remotemachine xterm -e scriptB
runs the script in a new temporary xterm
and then the sudo command is executed
without any problem.
Why does sudo think there's no tty in the
first case ?
TIA,

Hi all,
On behalf of the developer team, it is my pleasure to announce the
latest release of Aqualung, an advanced cross-platform gapless music
player. This release is the result of a year's work, much of which has
been done by our newly joined developer Jeremy Evans. Please see the
ChangeLog below for the highlights of this release.
As usual, the platform independent source tarball and the
self-extracting installer for Microsoft Windows, as well as up-to-date
documentation is immediately available from the project website:
http://aqualung.factorial.hu
Thanks,
Tom
2009-02-08 Tom Szilagyi <tszilagyi at users dot sourceforge dot net>
* Aqualung 0.9beta10
http://aqualung.factorial.hu
* Add programmable title format support.
This commit embeds a Lua interpreter inside of Aqualung for the
purpose of allowing the user full control over the title format. It
allows the user to use any metadata field that Aqualung recognizes,
as well as a few fields from the file info in order to compose a
title field. See the documentation update included in this release
for usage information for this feature.
* Loop playback enhancements:
New key bindings '<' and '>' for adjusting loop range start and end
(respectively) to the current playing position. Active only when
track repeat mode is on and a track is currently playing or paused.
Added tooltip showing loop range in percentage and time (if there is
a track loaded). Tooltips must be globally enabled for this feature.
* Allow the systray to be disabled even if support is compiled in.
* Add support for saving single playlists in M3U format. If the
playlist file name ends with .m3u, it will save in M3U format (one
filename per line) instead of the Aqualung XML format. This only
affects the logic around saving single playlists; if you save all
playlists at once, it will always use the XML format, because the
M3U format does not support multiple playlists.
* Add support for sndio backend, bringing the total number of
backends to five. libsndio was recently introduced in OpenBSD as
a simple audio API that supports OpenBSD's builtin sound server,
aucat.
* Add playlist context menu option 'Roll to active song'.
* Optionally combine Play and Pause buttons into a single button.
* Fix gapless MPEG audio playback (correct offset calculation) when
ID3v2 tag is present.
* Export can now copy files instead of reencoding them using the new
target format "Copy".
* A subset of input files can be forced to be copied instead of being
reencoded. There are two criteria for this: when the source file is
already in the target format, and when the source file matches any
of a comma-separated list of wildchards (similarly to the builder
exclusion list). Both options can be enabled/disabled from the
Export dialog.
* Handle HTTP/1.0 responses.
* When updating all feeds, insert 1 second delay between
individual feeds.
* Added right-click menu items for adding only new podcasts to playlist.
* Music Stores can now use relative paths instead of absolute ones,
allowing users to mount the same collection on different mount
points (just one use case). Implementation is based on the patch by
Russell Johnston, big thanks for both the idea and the
contribution. A checkbox for toggling this feature is added to the
Edit Store dialog (accessible via the right-click menu of stores).
* All filenames use the GLib filename encoding instead of locale
encoding. This is the proper and official way of doing it; if you
have issues using filenames with special characters, consider
setting the G_FILENAME_ENCODING or G_BROKEN_FILENAMES environment
variables. If you are using an UTF-8 locale (a very wise choice),
you have nothing to worry about.
* Add extra check for mad.h presence to configure.
* New store builder option to automatically remove non-existing files
from the store. It is disabled by default.
* Added new Swedish translation by Niklas Grahn.
* Numerous minor bugfixes.

Thanks a lot for your kind answers. Any of your suggestions work realtime?

Sorry for the crossposting, but I don't know which list is more
suitable to what I'm asking.
One friend of mine is looking for a solution based in Linux. I admit I
don't understand fully what he needs. That's why I am asking to you
gurus out there... :)
He needs something for level measurement of spectrograms, callibrated
as K-14, also for phase measurement. He used [1]a plug-in for Nuendo
in the past, but now he's looking for a netbook devoted only to this
task, and he wants to use an open source solution.

Any suggestions welcome.

Hi,
In the spirit of organizing a well executed Awards ceremony and due to
lack of interest from the business community in sponsoring the inaugural
Linux Audio Awards for 2009 I have decided to withdraw from organising
the event and will postpone the inaugural event to the next Linux Audio
Conference in 2010.
Hopefully conditions will be more suitable for sponsors to get involved
next year.
Cheers.

Hi everyone,
Fons, thanks to your essay "Using a DLL to filter time" [1], that you mentionned
in a discussion we had in August, I've put together a small library, named
Pendule, for accurate timing within a real time context. It's a tiny piece of
code, but offers a very easy to use replacement for gettimeofday().
Plus, it includes some benchmarking/measuring tools, that produce that sort of
fancy graphics (this one using a PCI hda intel card):
http://www.samalyse.com/code/pendule/shortgraph.png
Usage is very simple. first create an instance:
#include <pendule.h>
Pendule *pendule = pendule_new(buffer_size / sample_rate, bandwidth);
Then, in the realtime thread, update the loop every process cycle:
pendule_cycle(pendule);
And use pendule_gettime() instead of gettimeofday():
double current_time_in_seconds = pendule_gettime(pendule);
As expected, looking at the graph above, the obtained time doesn't drift as the
audio time, and has a lower jitter than the system time. Well, at least, it
works for me.
However, although my measures are pretty encouraging, I am not 100% sure of my
DLL implementation. Could you please review it ? It's there:
http://svn.samalyse.com/pendule/trunk/src/pendule.c
You can grab everything using svn:
svn co http://svn.samalyse.com/pendule/trunk pendule
I'd like to know how it works for others. You can easily test your
hardware/system and make graphs with:
./waf configure
./waf build
./measure
./graph
Check the README for more.

You're not the first US resident to deplore this...

I'm not so sure of that... The US finally have a
respectable president, we still have Berlusconi.
Italy is in crisis - and not only the economy.
Last weekend some kids (youngest was 17, and all
from 'respectable' families) set fire to a homeless
Indian sleeping outdours, just 'per divertirsi'...
