Hello all,
Ecasound 2.4.5 has been released! Releases notes follow:
1. Summary of changes
---------------------
Native support for FLAC files has been added using the
sndfile library.
New debugging tools for ecasound scripting and ECI
applicatin development
have been added. Bugs related to ecasound process return
values, memory
corruption in ECI apps, handling of 24/32bit big-endian
audio files,
robustness of mp3/ogg/flac/aac support, managing loop
devices, parsing user
input, and build errors on cygwin, have been fixed. A set of
new
processing ops for channel routing and mixing has been
added.
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 since last release
-----------------------------
* Full read/write support for flac files with support for
seeking.
Requires libsndfile 1.0.12 or newer.
* Some bugs in setting the ecasound return value have been
fixed.
Ecasound now properly signals errors like insufficient
write
permissions, or running out of storage space during
processing,
via non-zero return values. The possible return values
are now
also documented in ecasound(1).
* A new debugging mechanism controlled by ECASOUND_LOGFILE
and
ECASOUND_LOGLEVEL environment variables. This is meant
especially
for debugging ECI applications, and scripted uses of
ecasound.
You can test this for instance by issuing:
sh> ECASOUND_LOGLEVEL=ecalog.txt ecaplay *.wav
And look at 'ecalog.txt' afterwards. This mechanism for
ECI
debugging really should have been there from the start.
See
ecasound(1) for more details.
* A set of new audio operators have been added for channel
routing/mixing: -chcopy (alias for -erc), -chmove,
-chmute and
-chmix (alias for -erm). See the full documentation in
ecasound(1).
* The in-tree sources for readline-4.0 have been removed
from
the package. Originally, some time around 1999, readline
was included
to the package due to numerous problems with Linux
distros of the time
that came with old versions of readline. This however no
longer is the case.
Nowadays, pretty much all non-ancient systems have at
least readline-4.0,
and most have already readline-5.0. Ancient machines are
however still
supported. To this end, ecasound now provides an option
to compile with
readline disabled.
* Various bugfixes including: severe memory handling error
in ECI C
implementation, bugs in processing 24/32bit big-endian
audio files,
problems with interactive mode commands operating on
controllers, handling
loop devices when saving chainsetup state, batch
processing of setups with
mp3/ogg/flac/aac outputs, build errors on cygwin, ...
* Sourceforge.net bug items affected: #1415814, #1531042,
#1456510
