Hello all,

Ecasound 2.7.0 has been released! Releases notes follow:

0. Special note: Ten years of Ecasound!
---------------------------------------

This is the 10th year anniversary release for Ecasound! The first public 
version, 1.1.4r1, of Ecasound, licensed under GPL, was released on 30th 
June 1999. See the following mailing list post for a quick rundown of what 
has happened so far:

- http://eca.cx/ecasound-list/2009/07/0004.html

1. Summary of changes in this release
-------------------------------------

Initial Open Sound Control (OSC) interface for parameter control has
been added. New '-chorder' and '-eadb' options, and 'cop-get'
interactive mode command, have been added. Optional build time support
has been added for using liboil to optimize inner loops, giving a
small performance boost to many common use-scenarios. Various bugs
fixed in JACK support, mp3 output and option parsing. Fixes to build
problems in Mac OS X.

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.

Primary platform for running Ecasound is GNU/Linux. Ecasound can also be
run on many UNIX-derived systems such as FreeBSD, Mac OS X and Solaris.
Limited support for Windows is available through Cygwin. Ecasound is
licensed under the GPL. The Ecasound Control Interface (ECI) is licensed
under the LGPL.

3. Changes in 2.7.x series
--------------------------

v2.7.0:

* Open Sound Control (OSC) support. See the initial announcement
   mail sent to ecasound-list:
   http://eca.cx/ecasound-list/2009/04/0036-fixed.html
   Current interface is documented at:
   http://eca.cx/ecasound/Documentation/ecasound_osc_interface.txt
   The interface is still limited and subject to change in
   later releases, but it's a start.

* New '-chorder' operator that allows to reorder channels of
   an audio stream. Also duplication and omission of certain
   channels is possible. See ecasound(1) man page for more
   information.

* Added new amplify/gain variant '-eadb' that allows to specify
   the gain in dB. See the related mail thread:
   http://eca.cx/ecasound-list/2009/03/0034.html

* Refactored POSIX signal handling in ecasound. See the following
   mail for some rationale, as well as a list of changes.
   See mail thread:
   http://eca.cx/ecasound-list/2009/02/0027.html

* Various optimizations to Ecasound inner loops using
   the liboil library. See http://liboil.freedesktop.org/wiki/
   To enable the optimizations, liboil-0.3 development files
   need to be installed and '--enable-liboil' must be passed
   to Ecasound's configure script.

* New 'cop-get' interactive mode command. See the updated
   ecasound-iam(1) manual page for further info.

4. Interface and configuration file changes in 2.7 series
---------------------------------------------------------

v2.7.0:

Output of '-ev' operator has been renewed.

The name for default chainsetup created from command line is now
"untitled-chainsetup".

Most of the entries in the installed ecasoundrc file 
(in ${prefix}/share/ecasound/ecasoundrc), are now commented
out by default.

Major changes to the libecasound library public interface.
This should not really affect anyone anymore, as direct use of 
libecasound has been discouraged for a long time and it is
available only as a static library, but just in case someone
is still using it. See libecasound/ChangeLog for a detailed
list of changes.
