this year's first stable Ecasound release is now out!
Most of the final tuning for this release was done last Sunday while
watching and listening to the last sessions of 'laconf2'. Many thanks to
all the organizers and participants! And special thanks for the
excellant net coverage of the event!
But now, back to the 2.3.3 release -- here are the details:
1. Summary of changes
Bugs in ecasignalview, effect presets, NetECI protocol parser
and the C ECI implementation have been fixed. Many build system
issues, including errors in building against libsndfile-1.0.4
and older, have been resolved. A separate section covering
ecasound.el, the ecasound emacs interface, has been added to
the Ecasound Control Interface Guide. The Ecasound User's Guide
has also been updated.
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
* Preset handling fixes: When saving chainsetups containing
presets, values of preset parameters were not saved correctly.
Also problems with presets containing untitled parameters have
* New ecasoundrc(5) setting "autodetect" for "default-output"
has been added. When selected, libecasound will check for
JACK support and whether a JACK server is running, if not
found, check for ALSA, then OSS, and finally fallback to
using "rtnull". This feature is especially useful to apps
such as ecaplay.
* Fixes to ecasignalview: Proper cleanup after receiving an
interrupt from keyboard (SIGINT/CTRL-C) has been added.
Originally tested on FreeBSD, but helps on Linux as well.
* Ecasound Interactive Mode (EIAM) updates: Added new
command 'map-ladspa-id-list' to allow listing the available
plugins by their unique ID numbers. A special case
value of '-1' is now understood by 'cs-set-length'. This
allows undoing any previously set length value.
* Ecasound Control Interface (ECI) updates: Added a section
on ecasound.el - the Ecasound emacs interface - to the
ECI Guide . Several bugs have been fixed in the ECI
C implementation. A serious bug in NetECI protocol parser,
that caused parsing long (over 32 chars) commands to fail,
has also been fixed.
* Documentation updates: The Ecasound User's Guide  has
been updated. Also, a bug in the groff source for the
ecasound(1) man page that prevented man from showing the
last five pages of the document, has been fixed.
* Build system fixes: Problems in building against libsndfile-1.0.4
and older have been fixed. 'libecasound-config --libs' has been
fixed to return the full list of external libraries. Based
on recent discussions on linux-audio-dev, minor changes have
been made to processing CFLAGS, CXXFLAGS and LDFLAGS.
Full list of changes is available at
4. Interface and configuration file changes
* ecasoundrc(5) - "default-output": new value "autodetect" (default)
