Libgdither is a GPL'd library library for performing audio dithering on
PCM samples. The dithering process should be carried out before reducing
the bit width of PCM audio data (eg. float to 16 bit int conversions) to
preserve audio quality.
It can do conversions between any combination of:
in out (optionally interleaved)
-------------------------------------------------------------
normalised mono float 8bit unsigned ints
normalised mono double 16bit signed ints
32bit signed ints
normalised float
normalised double
At any bitdepth supported by the input and output formats
Instructions for testing are in

Patchage is a modular patch bay for jack (and soon alsa sequencer)
This release fixes glaringly obvious bugs, 0.0.3 is broken. Also, you
can now run patchage without installing (in the src directory).
Thanks to Steve Harris and pasp(a)ll.pl for pointing out said bugs.

Hi,
Just less than a week after some user complaints about that glossy-glass
light effect featured on the front panel display, here comes a couple of
fixes that were made into this rather minor dot release.
Now's the perfect time for a recommended upgrade: qjackctl 0.2.11 is here,
grab it from:
http://qjackctl.sourceforge.nethttp://sourceforge.net/projects/qjackctl
Simply as is, as taken from the changelog:
* Fixed Input/Output channels settings, being now either enabled when the
ALSA driver is selected for Capture/Playback only.
* Shiny display effect: after some conservative user complaints this pure
cosmetic feature is now made optional ;)
Enjoy.

Hello all,
I just finished the jMax-SDIF package version 0.8 for jMax 4.1 CVS.
You can now import SDIF files into a track of matrices, and export a track to
SDIF. There is also an sdifinfo object that reads and outputs information
about the contents of an SDIF file.
Download:
http://sourceforge.net/project/showfiles.php?group_id=26076&package_id=1062…
SDIF is the Sound Description Interchange Format, see
http://www.ircam.fr/sdif and the freesoftware wiki
http://freesoftware.ircam.fr/wiki/index.php?pagename=HomePage.
Cheers...

Oggz 0.8.4 Release
------------------
liboggz is a C library providing a simple programming interface for reading
and writing Ogg files and streams. Ogg is an interleaving data container
developed by Monty at Xiph.Org, originally to support the Ogg Vorbis audio
format.
This release is available as a source tarball at:
http://www.annodex.net/software/liboggz/download/liboggz-0.8.4.tar.gz
New in this release:
* added support for building on Symbian OS (by Colin Ward)
* new OGGZ_ERR_IO_AGAIN handling for network reads
* added test for reading packets one-by-one
* expanded --help output for oggzdump tool
* added option to run test suite under valgrind
Additionally, a thorough audit of memory leaks has been completed and
various minor bugs have been fixed.
About Oggz
----------
Oggz comprises liboggz and the command-line tools oggzdump and oggzdiff.
liboggz supports the flexibility afforded by the Ogg file format while
presenting the following API niceties:
* Full API documentation.
* Comprehensive test suite of read, write and seeking behavior.
* Developed and tested on GNU/Linux, Darwin/MacOSX, Win32 and
Symbian OS. May work on other Unix-like systems via GNU autoconf.
For Win32: nmake Makefiles, Visual Studio .NET 2003 solution files
and Visual C++ 6.0 workspace files are provided in the source
distribution.
* Strict adherence to the formatting requirements of Ogg bitstreams,
to ensure that only valid bitstreams are generated; writes can fail
if you try to write illegally structured packets.
* A simple, callback based open/read/close or open/write/close
interface to raw Ogg files.
* Writing automatically interleaves with packet queuing, and provides
callback based notification when this queue is empty
* A customisable seeking abstraction for seeking on multitrack Ogg
data. Seeking works easily and reliably on multitrack and multi-codec
streams, and can transparently parse Theora, Speex, Vorbis and Annodex
headers without requiring linking to those libraries. This allows
efficient use on servers and other devices that need to parse and
seek within Ogg files, but do not need to do a full media decode.
Full documentation of the liboggz API, customization and installation,
and mux and demux examples can be read online at:
http://www.annodex.net/software/liboggz/html/
Tools
-----
The Oggz source tarball also contains the following command-line tools,
which are useful for debugging and testing Ogg bitstreams:
* oggzdump: Hexdump packets of an Ogg file, or revert an Ogg file
from such a hexdump.
* oggzdiff: Hexdump the packets of two Ogg files and output
differences Oggz is Free Software, available under a BSD-style
license.

http://plugin.org.uk/timemachine/
Timemachine is a JACK app for recording sounds that have just happened.
It can also be used as a generic JACK sound recorder. Read the website for
more retails.
Changes
* Now builds properly without LASH installed (thanks to Joern Nettingsmeier)
* Can specify recording format on command line (wav or w64)
* Filename extension reflects the format (ie .w64 to help user confusion)
* Can specify ports to connect to on the command line
* Desktop icon (thanks to Anarcat) pixmaps/timemachine-icon.png
Known Bugs / Omisions
* There is a race condition - locks up the app, but recordings are OK.
Not fixed, as I dont understand the problem fully, and I've not
received a patch for it.
* TM wont auto-connect to JACK hardware capture ports, I've had one
request for this, but dont care enough to add it right now.

Hi everybody,
After the holiday season, and late for the 1st anniversary, here comes
another dot release for QjackCtl, the Qt GUI for the JACK Audio Connection
Kit:
Qjackctl 0.2.10 is out, with some minor enhancements and fixes.
>From the change log:
- New pre-shutdown script setup option, allowing to specify a shell-script
to be run before the JACK server daemon is shutted-down. This overrides
any previous shutdown script setting, which should be now moved onto the
existing post-shutdown script option, as to keep old procedural behaviour.
- Avoid stopping JACK prematurely with QProcess::kill() (oneliner fix);
stopping JACK will now take a little bit longer, but hopefully will take
the time to cleanup properly (thanks to Kjetil Matheussen).
- ALSA driver Duplex mode accepts alternate Input or Output device name.
- Context menu reset option is now always enabled (yet another suggestion
from Sampo Savolainen).
- Main display background gets shinny effect; adjusted system tray
background palette color mode.
- Priority and setup control is now a spinbox ranging from 0..89 (as
suggested by Florian Schmidt). Same for Periods/Buffer.
- Patchbay connection lines are now drawn correctly when items are
scrolled out of view. Additionally, the connection lines can now be
optionally drawn as bezier spline curves (big thanks to Wilfried Huss).
Just head to the homepage:
http://qjackctl.sourceforge.net
or, in case that's not up-to-date yet, to sourceforge's project page:
http://sourceforge.net/projects/qjackctl
Hope you enjoy.

Hi all,
I am pleased to announce the first beta release
(and the first public release, as well) of
Aqualung, a music player for GNU/Linux
--------------------------------------
Homepage: http://aqualung.sf.net
Aqualung is a new music player for the GNU/Linux operating system.
It plays audio files from your filesystem and has the feature of
inserting _no_gaps_ between adjacent tracks.
Aqualung is released under the GNU General Public License.
Features at a glance
====================
Supported file formats:
* Almost all sample-based, uncompressed formats (eg. WAV, AIFF, AU
etc.), files encoded with FLAC (the Free Lossless Audio Codec), Ogg
Vorbis and MPEG Audio files (including, but not limited to, MP3) are
supported. Naturally, any of these files can be mono or stereo.
Supported output devices:
* OSS and ALSA driver interface, as well as support for connecting to
the JACK Audio Connection Kit.
Key features:
* Continuous, gap-free playback of consecutive tracks! Your ears get
exactly what is in the files -- no silence inserted in between.
* Ability to convert sample rates between the input file and the
output device, in high quality. (Thanks to libsamplerate!)
* LADSPA plugin support -- you can use any suitable LADSPA plugin to
enhance the music you are listening to.
Some other niceties:
* Internally working volume and balance controls (not touching the
soundcard mixer).
* Support for multiple skins; changing them is possible at any time.
* Support for random seeking during playback.
* Track repeat, List repeat and Shuffle mode (besides normal playback)
* All windows are sizable. You can stretch the main window
horizontally for more accurate seeking.
* State persistence via XML config files. Aqualung will come up in the
same state as it was when you closed it, including playback modes,
volume & balance settings, currently processing LADSPA plugins,
window sizes, positions & visibility, and other miscellaneous
options.
In addition to all this, Aqualung comes with a Music Store that is an
XML-based music database, capable of storing various metadata about
music on your computer (including, but not limited to, the names of
artists, and the titles of records and tracks). This is much more
efficient than the all-in-one Winamp/XMMS playlist.
Hope you will like this program. Please report any problems.
Tom
