[linux-audio-announce] ecasound 2.3.0 released

by Kai Vehmanen

1. A short summary of changes A set of severe bugs in audio mixing code have been fixed. Pyecasound build process has been improved. Reporting chainsetup parsing errors has been improved significantly. Support for the JACK 0.80 transport interface has been added. Support for reading and writing aiff, snd and au files has been fixed. Changes have been made to ensure correct operation with the NPTL package recently added to Linux kernel and glibc. A serious bug in metronome timing was fixed. Minor bugs in dynamic sample rate changes, MIDI-server initialization and the ewf file format have been fixed. --- 2. What is Ecasound? Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. --- 3. Changes since last release * Support for JACK 0.80 transport interface. The recently released JACK 0.80.0 marks another milestone for Linux audio development. The new transport interface allows concurrent use of multiple independent audio applications with full sample-accurate transport synchronization. This release of Ecasound provides full support for the new transport API. See the following links to ecasound-list postings that give examples of how to use Ecasound with the new transport API: http://eca.cx/ecasound-list/2003/08/0005.html http://eca.cx/ecasound-list/2003/08/0070.html * Metronome timing bug. There was a subtle bug in the pulse gate operator that is used to generate the metronome signal. This bug caused a small (<0.5%) timing error in metronome speed. The bug has been fixed, but the change in speed might cause problems for working with sessions recorded with previous versions of Ecasound. Thanks to Carsten Bauer for finding the bug. Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes Libecasound interface version number was incremented to 11. This release is backwards compatible with interface versions 9 and 10. See 'ecasound/libecasound/ChangeLog' for a detailed list of changes. Libkvutils interface version number was incremented to 6. This release is backwards compatible with versions 5 and 4. See 'ecasound/kvutils/ChangeLog' for a detailed list of changes. Note! Using libecasound and libkvutils outside Ecasound has been discouraged since the release of 2.2.0 in Jan 2003. The interface changes introduced in this 2.3.0 release should only affect a small group of distributors and developers. Apps such as Ecamegapedal need to be recompiled only if you want to take advantage of the new features introduced in the latest Ecasound release. --- 5.

[linux-audio-announce] JACK Release 0.80.0

by Taybin Rutkin

JACK RELEASE 0.80.0 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. CHANGES: New transport API (details (of a sort) below). new example client for control the transport. ignoring of first xrun on jackd startup. Much more portable across processors (details below). jackd -v (--verbose) now prints useful transport state change information for debugging JACK and clients. Also reports timeout info in seconds, not microseconds now. new dummy driver (along side the existing alsa and portaudio drivers). Removed incomplete Solaris driver. support for asymmetric soundcards (for example, es1968 chip has interleaved stereo for playback but non-interleaved stereo for capture). Now enforces power of two sized buffer lengths. Many minor bug fixes. DETAILS: The new transport API: It has greatly changed; if you're a developer, please see the documentation. But as a highlight: jack_set_transport_info() and jack_engine_takeover_timebase(), (the old timebase master interfaces) now do nothing. Instead, use jack_set_timebase_callback(). Portability: <jack/types.h> typedefs are now defined using the C99 standard fixed-size integer typedefs. These new typedefs are binary compatible with 32-bit platforms, but not 64-bit machines. Programs using printf on these values will get GCC compiler warnings. To suppress the warnings, use the corresponding C99 printf specifications defined in <inttypes.h>. That header is already implicitly included by <jack/types.h>, but can also be included explicitly to maintain compatibility with older versions of JACK without messy #ifdef's. Adding explicit casts will also work, but may suppress future warnings you might want to see. jack_get_sample_rate() now returns jack_nframes_t rather than unsigned long. These are the same on 32-bit machines, but not on 64-bit platforms. These changes were made to accommodate the increasingly popular 64-bit platforms; specifically, the new Opteron with it's 32-bit compatibility mode. 32-bit mode probably won't work, but if all programs are compiled as 64-bit (which Jack supports), it should work fine.

[linux-audio-announce] ecamegapedal 0.4.3 released

by Kai Vehmanen

1. A short summary of changes Bugs in build process were fixed. Support for transport functionality in JACK 0.77.0 and newer has been added. Transport functions are enabeld only if Ecamegapedal is compiled against Ecasound newer than 2.2.3. Ecamegapedal was verified to work if compiled against Qt-3.2. --- 2. What is Ecamegapedal? Ecamegapedal is a real-time effect processor software with a graphical user interface for controlling the effect parameters. It is meant to be used as a virtual guitar-fx or studio effect box. In addition to real-time operation, ecamegapedal also supports reading from and writing to audio files. All audio object and effect plugin types provided by the ecasound libraries are supported. This includes ALSA, JACK, OSS, aRts, over 20 file formats, over 30 effect types, LADSPA plugins and multi-operator effect presets. Ecamegapedal's implementation is based on ecasound and Qt libraries. Ecamegapedal is licensed under the GPL. --- 3. Contributors Patches Junichi Uekawa (1) -- Qt -rpath build optimization Kai Vehmanen (1) -- JACK transport support --- 4.

[linux-audio-announce] jackEQ: dj eq and meter.

by Patrick Shirkey

For those of you who are interested in dj tools or tools for live performance, Steve Harris has made a new plugin called DJ EQ which is a three band EQ commonly found on dj mixing consoles. It's currently only available in the snapshots directory. You may also be interested in a new app we are creating based on the code from JAMin. It's called jackEQ. http://sf.net/projects/jackeq. No webpage yet and only cvs. It is in its infancy but it already connects to JACK and has a one channel (multiple i/o via qjackconnect) EQ and meter. I would like it to be able to do all these things eventually: unlimited channels. jack port connection ala freq tweak style route signal to monitor if monitor button is toggled for channel independant monitor gain control (with meter) and output to alternate alsa_pcm:outs With the above I could use my four channel card as a complete djing tool . You could also use a two channel card in a similar (mono) way. The monitor will be assignable to seperate output channels than the main outs. All the channels can be routed to it if needed. The eq's are all adjusted before the signal arrives at the monitor. This is how I intend to use it: mon ch1 ch2 ch3 ch4 echo ardour | |----------------| | out1&2 out3&4 internal internal If you are interested in contributing please join the mailing list. -- Patrick Shirkey - Boost Hardware Ltd. Http://www.boosthardware.com Http://www.djcj.org - The Linux Audio Users guide ======================================== Being on stage with the band in front of crowds shouting, "Get off! No! We want normal music!", I think that was more like acting than anything I've ever done. Goldie, 8 Nov, 2002 The Scotsman
