[linux-audio-announce] [ANN] Jack Audio Connection Kit 0.98.16 Release

by Taybin Rutkin

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.

[linux-audio-announce] [ANN] Prerelease of libgdither 0.2 dithering library

by Steve Harris

Invitation for testing and API comments. http://plugin.org.uk/libgdither/ 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 http://plugin.org.uk/libgdither/libgdither-0.2/gdither.h Examples of use can be found in http://plugin.org.uk/libgdither/libgdither-0.2/examples/ex1.c Comments welcome, Steve

[linux-audio-announce] [ANN] qjackctl 0.2.11 released!

by Rui Nuno Capela

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.net http://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. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-announce] liboggz 0.8.4 Released

by Conrad Parker

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. License ------- Oggz is Free Software, available under a BSD style license. More information is available online at the Oggz homepage: http://www.annodex.net/software/liboggz/ enjoy :) -- Conrad Parker Senior Software Engineer, Continuous Media Web, CSIRO Australia http://www.annodex.net/ http://www.ict.csiro.au/cmweb/
