The Aqualung development team is pleased to announce the latest release of the Aqualung music player. Aqualung is an advanced music player originally targeted at the GNU/Linux operating system, today also running on FreeBSD, OpenBSD and Microsoft Windows. It plays audio CDs, internet radio streams and podcasts as well as soundfiles in just about any audio format and has the feature of inserting no gaps between adjacent tracks. The ChangeLog lists major new features and is included below. Packagers, please note that from this release, TagLib is no longer a dependency of Aqualung. Website: http://aqualung.sf.net Enjoy, Tom 2007-12-19 Tom Szilagyi <tszilagyi at users dot sourceforge dot net> * Aqualung 0.9beta9 http://aqualung.sf.net This is a major release bringing significant new functionality and many important fixes. All users are encouraged to upgrade. As always, the up-to-date User Manual is available at: http://aqualung.sourceforge.net/?tab=docs Major additions: * Fundamentally new Metadata system, using native decoders and private code instead of TagLib to provide complete support for reading and writing metadata, including ID3v1, ID3v2.3, ID3v2.4, APE, Ogg Xiph comments and FLAC picture frames, as well as read-only support for ReplayGain in Musepack stream data and various metadata received in internet radio streams. Aqualung also provides a batch tagger facility to quickly propagate Music Store metadata to file metadata. * Support for podcasts. Aqualung can subscribe to RSS and Atom audio podcasts, and automatically download and add new files to the Music Store. Optional limits for the age, size and number of downloaded files can be set. * Support for exporting files from Music Store or Playlist with audio transcoding and intelligent metadata transfer. Useful for burning your favourite tracks to CD, filling your portable player, etc. * Aqualung now compiles and runs on OpenBSD. * Smoother skin changing. * Option to disable skin support (for themed environments). * Lots of fixes, cleanups & refactoring. DROPPED DEPENDENCIES: * TagLib is not used anymore.

[ANN] Qsynth 0.3.2 (unstable-qt4) is out!

by Rui Nuno Capela

Yes, it's about time. Much as the long due FluidSynth 1.0.8 release, really "Its about funky time!". Time also for season greetings and some gift exchange. Don't ask for a second best, here you have the finest pair of socks for the holiday ;) Qsynth 0.3.2 (unstable-qt4) is out! The official download site is, as always have been: http://qsynth.sourceforge.net http://sourceforge.net/projects/qsynth Straight from the change-log: - A new option to start the program minimized when the system tray icon is enabled, is now available from Setup/Misc/Start minimized to system tray. - Regression from QSystemTrayIcon (Qt4 >= 4.2) implementation, at least on X11 environments: while the main application widget was minimized to the system-tray, closing any other top-level widget was causing the immediate and unexpected application shutdown. - Minor corrections on the output peak meter scale aesthetics. - Tool/child windows position and size preservation fixed. - Orphaned MIDI device name no longer mistaken when switching between MIDI drivers on engine setup. - A bit more of precision is achieved over the output peak meters. - Messages line limit was not being checked, now honored. - Simple as it could ever be, the build executive summary report is now given on configure. - Get configure to try and detect the correct qmake location and insert it the search order, so let the qt4 tools take precedence when --with-qt option is given and older qt3 ones coexist and are found located ahead in the PATH. - The infamous "Keep child windows always on top" global option is now supposed to behave a little better when disabled, layering child windows as naturally as far the window manager dictates. - Inspired on Andreas Persson patch, while on qjackctl-devel, which made it possible to compile and run with older Qt 4.1, similar arrangements were carried out on qsynth too, without hesitation. - Main panel spin-boxes gets accelerated when stressed (Qt >= 4.2). Cheers && Enjoy, -- rncbc aka Rui Nuno Capela

cross platform network audio ... port it now!

by Paul Davis

http://createdigitalmusic.com/2007/12/17/wormhole2-tool-routes-audio-over-n… as if you needed another reason for eternal gratitude from the entire planet ... could be a pair of JACK client or even a JACK backend, or a replacement/alternative to netjack .... and lets try to temporarily ignore the call from Anders to port to "Linux VST", which benefits precisely 1 or 2 applications :) --p

new releases

by Fons Adriaensen

Some new stuff on <http://www.kokkinizita.net/linuxaudio/downloads> Two new shared libraries: zita-resampler-0.1.0 zita-convolver-0.1.0 Both C++. Unlike the libcl* series which are my 'personal toolset' that I assume nobody will want to re-use, the zita series of libraries will be fully documented. The resampler already comes with HTML documentation, for the convolver this is 'under construction'. This release of zita-convolver is provided mainly as a dependency of jconv-0.2.0 Command line JACK app for real-time fft-based partitioned convolution with non-uniform partition size. Provides low or zero delay processing at moderate CPU loads. Any convolution matrix up to 64 * 64 as long as your CPU(s) can take it. From the README: New in this release ------------------- - The convolution engine has been separated into a shared library, libzita-convolver. For more information on the internals of the convolution engine, see the documentation provided with this library. - A non-real-time, file processing version of jconv, called fconv, has been added. It accepts the same configuration files. The input can be any file readable by libsndfile. The output will be a 24- bit WAV or WAVEX (for more than 2 channels). - Large configurations requiring too much memory will fail with an error message rather than just crash with a segfault. - Now uses jack_client_open(), so multiple instances can be run even without using the -N <jack_name> option. - Optional use of FFTW_MEASURE. - Added the mkwavex utility, converts multichannel responses stored in separate files to a single WAVEX file. - New config files for some AMB reverbs. The nicest one of these is York Minster, which really sounds great. Enjoy ! -- FA Laboratorio di Acustica ed Elettroacustica Parma, Italia Lascia la spina, cogli la rosa.

How to save and restore MIDI connexion (ALSA sequencer)

Hello ! Thanks for your response but I don't succeed to have something working :( my code : init: if (snd_seq_open(&seq, "default", SND_SEQ_OPEN_DUPLEX, 0) >= 0) { m_iClient = snd_seq_set_client_name(seq, "LiveMix"); m_iPort = snd_seq_create_simple_port(seq, "control", 0, SND_SEQ_PORT_TYPE_MIDI_GENERIC | SND_SEQ_PORT_TYPE_SOFTWARE | SND_SEQ_PORT_TYPE_APPLICATION); m_iMidi = snd_seq_create_simple_port(seq, "control", SND_SEQ_PORT_CAP_READ | SND_SEQ_PORT_CAP_SUBS_READ | SND_SEQ_PORT_CAP_WRITE | SND_SEQ_PORT_CAP_SUBS_WRITE, SND_SEQ_PORT_TYPE_APPLICATION); } else { qDebug() << "The ALSA MIDI system is not available.

Hello, I've installed the slv2 package on my machine but can't run any plugins? When I start lv2_jack_host get lots of known plugins URI's like http://ll-plugins.nongnu.org/lv2/dev/klaviatur/0.0.0 which I want to run. But when I start I get lv2_jack_host http://ll-plugins.nongnu.org/lv2/dev/klaviatur/0.0.0 Failed to find plugin http://ll-plugins.nongnu.org/lv2/dev/klaviatur/0.0.0. also running it with lv2_jack_host /usr/lib/lv2/klaviatur.lv2/manifest.ttl URI: /usr/lib/lv2/klaviatur.lv2/manifest.ttl Failed to find plugin /usr/lib/lv2/klaviatur.lv2/manifest.ttl. or lv2_jack_host file://usr/lib/lv2/klaviatur.lv2/manifest.ttl URI: file://usr/lib/lv2/klaviatur.lv2/manifest.ttl Failed to find plugin file://usr/lib/lv2/klaviatur.lv2/manifest.ttl. fails.

IR/phase response tool anyone?

by Joern Nettingsmeier

hi everyone! i'm looking for a simple way of creating a system's phase response graph from its impulse response. i know the maths is trivial, but i couldn't find a program that does it... anyone? if possible, i'd prefer a quick solution that does not involve having to learn GNU octave or the intricacies of gnuplot :) thanks, jörn -- jörn nettingsmeier home://germany/45128 essen/lortzingstr. 11/ http://spunk.dnsalias.org phone://+49/201/491621 Kurt is up in Heaven now.

[PATCH] jack dbus and logs improvement

by Nedko Arnaudov

Attached are two patches: * The logs patch replaces various calls to fprintf(),printf() and fputs() with calls to jack_error() and newly appeared jack_info() functionality. It also fixes some obvious error/info log mismatches in current code. * The dbus patch provides additional fronted to jack server, alternative to jackd. the dbus object is auto activatated when needed. Starting and stopping of the jack server are methods of the dbus object. Other methods are for setting/getting jack settings. Settings are being persisted. D-Bus patch requires logs patch. As currently exported it also requires midi-alsa-munge patch, but this is not real requirement. So patch apply order is (against latest svn, tested with r1070): * jackd-midi-alsa-munge-r1051.patch (p0) * jack-logs-20071209-r1070.patch (p1) * jack-dbus-20071209-r1070.patch (p1) What is not implemented yet: * Provide access to clock source parameter (tricky) * Provide access to debug-timer parameter (not fully documented - optarg) * Send signals to (control) apps (status changes, connections, clients, port renames, xruns, error and info logs) * In client library, when compiled with dbus support, try to start via dbus frontend first (auto-activation) * Implement configurator supporting multiple user configurations (separate D-Bus object) D-Bus patch currently requires dbus-glib for main code and libxml2 for settings persistence. Applying patch enables configure time checks for required libraries and if they are not present, corresponding feature is not built. Currently there is problem with ffado driver (freebob works). libffado uses libxml++ that uses libxml2. libxml2 has quite lot of global things, Including global hooks used by libxml++ and initialized in constructor global object. To avoid crashes when ffado driver is available, it is ignored by the jackdbus frontend (it is still available in jackd). This is temporary solution. I could of course don't use libxml2 but this will only delay effect in ffado driver until some other driver is starts using libxml2. After compiling and installing jackdbus, you will get also a small python app, jack_control that allows accessing of jackdbus. jack_control is test app, and while quite usable is not supposed to be in line with full-featured jack control apps like qjackctl and patchage. Theory of operation: JACK server works in background with log file and settings preserved in ~/.jackdbus/ directory. jack controller dbus object is autoactivated when accessed. Thus jack server works in background while allowing to access it post factum, either logs, settings or start/stop. Multiconfig functionality is provided by separate object to be reused by control apps like patchage and qjackctl. All of them will reuse jack presets and user will get transparent workflow. If they adapt it. Dave, Rui? -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

jack app help

by Stefanos K

hello, I am trying to develop an app using jack. My first goal is to play a stereo wav. I've used clockloop http://plugin.org.uk/clockloop by Steve Harris as a starting point. It uses libsndfile to open a mono wav. I've reached a point where 2 outputs are created and connected to the first two outputs of the sound card. I managed to send a mono file to both outs. I've opened a stereo file, but I'm having trouble outputting it correctly. I am a bit confused on how to continue. If someone could give me some pointers would be much appreciated. thanks in advance stefanos This is what I have so far: //================ audio.c =============== /* * Copyright (C) 2003 Steve Harris * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
