JACK RELEASE 0.98.16
JACK is a low-latency audio server, written primarily for the GNU/Linux
operating system. It can connect a number of different applications to
an audio device, as well as allowing them to share audio between
themselves. Its clients can run in their own processes (ie. as normal
applications), or can they can run within the JACK server (ie. as a
"plugin").
JACK is different from other audio server efforts in that it has been
designed from the ground up to be suitable for professional audio work.
This means that it focuses on two key areas: synchronous execution of
all clients, and low latency operation.
JACK is available at http://jackit.sf.net
--CHANGES--
Buffer resizing enabled by default.
Added jack_ringbuffer_peak() to API.
Added jack_last_frame_time() to API.
--verbose will print the maximum usecs used on jackd termination.
Better compatibility with NPTL.
--version output changed for easier parsing.
New --unlock/-u option so that large libraries (gtk, qt, fltk, wine)
aren't memlocked.
Jack's tmp files now have the uid appended to them, so if there is a
crash, and then another user tries to use jack, it will still work.
New jack_create_thread() cleans up threading for portability. Available
for use by jack clients too.
New CoreAudio driver from the Jackosx project included in jack tree.
Prettier configure output.
and of course, updated documentation, better error reporting, and misc
internal fixes and cleanups.
Invitation for testing and API comments.

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
http://plugin.org.uk/libgdither/TESTING
Basic docs can be found in

Comments welcome,

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.
More information, downloads, and a screenshot at

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.
