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 2.9.x series

* Thanks to Jeremy Salwen, Ecasound now supports LV2 plugins!
   See http://eca.cx/ecasound/Documentation/examples.html#lv2 for
   simple usage information.

* New commands: cop-bypass, cop-is-bypassed, stop-sync, c-is-muted,

* Chain operator state is now flushed when position is changed with
   a seek. Previously Ecasound effects worked like their analogue
   counterparts, and e.g. a delay operator would not flush its internal
   delay line when a seek was performed.

* Various minor bug fixes, see NEWS file and git history.

Full list of changes is available at:
  - http://www.eca.cx/ecasound/history.php

4. Interface and configuration file changes in 2.9? series

* New params to c-bypass and c-mute
   - 'c-mute on' -> set mute on
   - 'c-mute toggle' -> old behaviour, toggle existing setting
   - 'c-mute' -> old behaviour as well
   - 'c-is-muted' -> returns current state

   And same applies to 'c-bypass'.

* 'cop-remove' and 'ctrl-remove' cannot be used on a connected
   chainsetup anymore.

* Python C implementation of the ECI (Ecasound Control Interface) now
   deprecated. The Python ECI implementation is still available,
   and has been updated to work with more recent versions of Python.

* RPM packaging files (ecasound.spec) have been removed from git
   and tarball releases due. They've not been maintained since 2006
   and serve no practical purpose anymore.
