-----------------------------------------------------------------------
18032003 (v2.2.2) -** stable release **-
- edi-entries: edi-35 and edi-36 added
- added: ecacontrol.py - a native python implementation of
the ECI API [jhalttun]

filename has a url-prefix
- added: author name to the description of LADSPA plugins
- added: latest config.guess and config.sub added to
the dist package
- added: ecamonitor - a warning is printed if you try to
run with python-1.x; python-2.x is required
- added: new tutorials pages added to documentations;
see Documentation/index.html
- changed: ecasound.el updated to 0.8.2, lots of small
changes, see ecasound.el for details [mlang]
- changed: alsa-0.9 - better support for pcm devices such as
dmix which have strict period size constraints
- fixed: libecasound sample conversion unit test failed when
compiled with gcc-2.91.66 on certain platforms
- fixed: compile failed on systems that don't have nanosleep()
- fixed: subtle bug in -kl and -kl2 (and possibly others)
with fade lengths under 1s
- fixed: alsa-0.9 - prevent ecasound from prefilling too
much data to output devices
- fixed: a ':' in LADSPA plugins parameter name confused
ecasound (swh's sc4 is one example)
- fixed: theoretical problem with ecalength argument
parsing
- fixed: use LOGNAME instead of USER for creating temporary
files for ecanormalize and ecafixdc
- fixed: -tl has been broken since 2.2.0-pre5
- fixed: copp-list dumped core if no was cop selected
15022003 (v2.2.1) -** stable release **-
- added: sane default param hints for chainops: -ec, -etd,
-ete, -etf, -etl, -etm, -etp, -etr and -epp
- added: if configured with JACK-support, ecasound will
fetch the correct bufsize and srate parameters from
the JACK server when connecting a chainsetup with
JACK inputs or outputs

resampling library; used both by the resample
audio i/o object and the pitch shifter chainop (-ei);
enable with --with-libsamplerate
- added: --disable-libsamplerate; don't enable libsamplerate
support even if the library is found during configure
- added: resample-hq audio object type; like resample, but
use the highest available resampling quality;
currently only has an effect if libsamplerate
support is enabled
- added: alternative UNIX signal handling for platforms that
don't provide sigwait() (cygwin is one)
- changed: ecasoundrc - ladspa-plugin-directory can contain
multiple directories, separated by colons; this
change was done to avoid any confusion with
the LADSPA_PATH syntax and ecasoundrc
- changed: rewritten much of the JACK slave-mode code; enables
much faster and reliable transport-sync
- fixed: compiling pyecasound failed on alpha w/ gcc-3.2

24062002 (v2.1dev10)
- added: -G:mgrtype,optstring switch for setting
audio object manager level options
- added: -G:jack,client_name,operation_mode option; see

man page for better documentation
- added: pyecasound - if python version is 2.2 or higher,
pyeca.py sets custom dlopen flags before importing
the actual pyecasound python module; this makes it
possible to access ecasound's plugins (ALSA, JACK,
libaudiofile) from python ECI apps
- added: ecasoundrc - 'default-audio-format'; same syntax
as with the -f option; defaults to s16_le,2,44100,i

set automatically - if object sample rates don't
match, an error is printed
- added: edi-21 implemented; a much improved framework
for handling audio position information is now
in place; -kl, -kl2 and -klg are now position
aware - changing chainsetup position also affects
controller sources

to pyecasound.so
- changed: programmer's guide updated; added a new chapter
about library organization
- changed: minor user's guide update
- changed: looping with -tl always loops from the start;
-y can't be used for setting the loop start
offset -> ewf-files should be used instead
- changed: s24_le and s24_be sample formats are interpreted
as three-byte values, not as four-byte
24-in-32bits values as before; to access
unpacked 24bit data, use s32_le and s32_be
formats instead
- changed: configure.in cleanup
- changed: the libkvutils binary API has changes so its
version number was changed from 3:0:1 to 3:0:0
(libkvutils.so.3); this interface will be
frozen together with libecasound.so.8
- changed: rewritten rtnull implementation; now imitates
soundcard behaviour much more accurately
- changed: numerous portability improvements to the
autoconf scripts

first command
- fixed: after mp3/ogg/mikmod/timidity objects had reached
finished state, playback couldn't be started
without doing a disconnect-connect

is abruptly shutdown and then restarted
- fixed: sometimes an incorrect length-field was written to
newly created wav-files
- fixed: problems with using ewf-files with doublebuffering

chainsetup was connected but the resulting
setup was not valid for reconnection
- fixed: -klg didn't work as documented
16012002 (v2.1dev7)
- edi-entries: edi-12
- added: a watchdog thread that handles thread cleanup;
this is needed especially for audio and chainop
objects which create their own threads (like jack)
- changed: unification of interactive and passive
modes; running ecasound without -c is now
pretty close to "echo run | ecasound -c cmds"
- changed: if an invalid chainsetup is given on the command
line, and -c is given, ecasound will print an
error but will not exit as it did before; you
can continue editing in the ia-mode to check
what was wrong in the setup
- changed: compilation of eca-iamode-parser.cpp is now
significantly faster and takes less resources;
this should fix problems with compiling ecasound
on machines with <256MB of memory
- fixed: audio-manager.h was missing from the dist-package

containing white-space; either by quoting
with ("a token") or backslash espacing
(a\ token) [junichi]
- removed: ecasoundrc - 'user-resource-directory' tag
removed; user-specific preset/oscillator
definition directory now '~/.ecasound'
- changed: ecasoundrc - to avoid versioning conflicts,
all 'ext-*' tags are renamed; see ecasoundrc(5)
- changed: 'make install' will now overwrite old
data files ({prefix}/share/ecasound/*)
- fixed: problems with automake1.5

devices connected to multiple input objects
- fixed: using loop devices in setups with non-default
internal sample rate could cause unwanted
resampling
- fixed: -kog and -f were broken (since dev4)
- fixed: bugs in passing audio format params to
mp3 and ogg encoders; note! update your
~/.ecasoundrc to match the new defaults,
see ecasoundrc(5) man page

- fixed: work-around for environments without the C99 stdint.h
header file [anarcat]
- fixed: eiam - problems with 'cs-set-position-samples',
'cs-rewind' and 'cs-forward' with unconnected
chainsetups
31102001 (v2.1dev4)
- added: eiam - 'cs-option' commmand; although explicit use
of cmd-line options as iactive-mod commands (like
"-i:file.wav") is still supported, "cs-option
-i:file.wav" is now the preferred syntax
- removed: ecasound FAQ file - it only contains about
a pageful of useful text - I moved that
precious piece of content to the user's
guide :)

- added: engine profiling info (printed to stderr)
- added: -z:multitrack, -z:nomultitrack for forced enabling
and disabling of multitrack-mode
- added: variable-like preset parameters; it's now possible
to bind one preset parameter to multiple chainops'
parameters (control multiple settings with one
parameter)
- added: support for describing preset parameters (edi-3)
- changed: pyecasound - makefile-hack that allows pyecasound
to work even though compiled against libecasound
and libkvutils that are not installed to
a directory listed in /etc/ld.so.conf
- changed: db-subsystem - is put to sleep more
aggressively, which should further decrease
its cpu-load
- changed: db-subsystem - runs once again under sched_fifo
scheduling if -r is enabled

rt-object-only chainsetups
- fixed: misplaced tab prevented eci.py from working
with python 2.1 (nested scopes)

stopped in multitrack mode and -z:db was enabled,
it continued producing unwanted noise to the
monitor output
- fixed: eiam - ladspa-register output had plugin names
and descriptions mixed

sample rate conversions - instead a warning is issued
121199 (v1.6.2d6)
- added: all ia-mode commands now implemented&documented
- added: a little bit of artificial intelligence to command
interpreting :) - as an example, if you want to start
processing but no chainsetup is connected, ecasound
tries to connect the currently selected setup, etc
- fixed: given a certain combination of forward and rewind
commands, processing wouldn't start anymore
- fixed: delay surround mode now works normally
- fixed: ecatools - files not in the default sample format
were not handled properly
- fixed: some bugs in double-buffering
- removed: adding chain operators to multiple chains is no
longer possile - this makes the library interface

defaults to 'false'
- added: -z:psr option (see above)
- changed: reimplemented signal handling using POSIX
signal handlers (ANSI interface was used before)

binary RPM packages
- added: if underruns/overruns occur when using ALSA devices,
a warning message is given on exit (stderr)
- changed: gcc's -fomit-frame-pointer isn't used anymore
(caused lots of problems with exceptions)

error.h header file
- fixed: pan effect (-epp) decreased overall volume level

ALSA support
- added: support for ALSA MIDI devices (/dev/snd/midiCxDy)
- changed: rewrote the MIDI-input sybsystem (works better
with multiple controllers)
- fixed: kvutils -package also needed configure script fixes
to recognise FreeBSD's pthread implementation
- fixed: although "make install" worked in all cases,
plain "make" didn't work if installing ecasound
1.5.x for the first time
- fixed: crashed if you had two chainsetups with ALSA devices
and you tried to delete the other one
- fixed: crashed in some conditions when closing .wav and
.raw files
040999 (v1.5.9r5)
- changed: qtecasound - in all windows with list widgets,
if no item is selected, current item (if any)
is used for all operations
- changed: in most cases, '-r' option (raise priority) isn't
needed anymore (see ecasound and ecasoundrc man
pages for more info)
- changed ecasoundrc - 'x-text-editor-use-getenv' is now
'true' by default
- fixed: resonant lowpass filter was once again broken
- fixed: configure should now recognise FreeBSD's pthread
implementation (not tested yet)

- fixed: qtecasound - waveform view positioning is now much
more precise than before
- fixed: qtecasound - core dumps when exiting
020999 (v1.5.7r5)
- added: qtecasound - chainsetup window now has a wave-edit
button which loads the active file into a external
wave editor; defaults to "snd", can be changed by
changing the value of "x-wave-editor" in
~/.ecasoundrc
- added: qtecasound - support for external text editors
(can be launched from session window) - saves the
active chainsetup to a text file, loads it to an
editor and afterwards updates file's content back
to ecasound - if "x-text-editor-use-getenv true"
is specified in ~/.ecasoundrc, ecasound uses
EDITOR environment variable if it's available,
otherwise value of "x-default-text-editor" is
used ... an of course, default value for this is
the ultimate musicians tool: emacs! ;)
- changed: qtecasound - some minor changes to session and
chainsetup widgets
- changed: .ews format (wave view cache files) has changed,
ecasound can still read the old format
- changed: qtecasound - "activate" button changed to a
"change status" button which rotates through
inactive->active->connected->inactive ...
- fixed: qtecasound - enabling/disabling chains sometimes
resulted in program crashes
- fixed: all structs found in ecasound source code now
use the standard type definations from sys/type.h
(format "[u_]int'bits'_t") - this should solve some
compatibility problems with non-x86 platforms -
thanks for Guenter Geiger for notifying about these
- fixed: a few fixes to the new double-buffering system -
lots of buffer parameter fine-tuning
290899 (v1.5.6r5)
- added: "-z:feature" command line option for enabling
misc features
- added: mmap-based double-buffering now disabled by
default, enable it with "-z:db" or by putting
"default-to-double-buffering true" to your
~/.ecasoundrc
- added: when upgrading ecasound, new resource values
will be automatically added to your ~/.ecasoundrc
- fixed: crashes when getting error messages from alsa-lib
(for instance when using invalid card and device
numbers)
- fixed: a few Makefile problems in 1.5.x versions
(thanks for Vadim Tkachenko for reporting these)
280899 (v1.5.5r5)
- added: improvements to resource file (~/.ecasoundrc)
handling - resource files can now have comment
lines (lines beginning with a '#'); resource
files are rewritten only if resource values are
changed directly from ecasound; '=' sign can be
used as a name-value separator
- fixed: since version 1.5.2r5, .cdr input/output hasn't
worked (reversed byteorder when reading .crd
files, .cdr output files weren't padded correctly)
270899 (v1.5.4r5)
- added: experimental support for double-buffered
mmap() file i/o (currently implemented
for .wav/.raw input only)
- fixed: thread-priority was always risen (once again)
210899 (v1.5.3r5)
- added: a lowpass filter effect (-ef2); not as good
as the other lowpass filters (-efl and -ef3), but
should be a bit faster
- fixed: 1.5.2r5 was really _slow_ (a file seek bug)
200899 (v1.5.2r5)
- added: "-x" command line option - truncate outputs
- added: sample rate conversion (resampling) - if audio
object's sample rate differs from ecasound's
internal rate the signal gets resampled
(internal rate is currently 44100; can be
changed from samplebuffer.h)
- changed: gcc 2.95.1 is now used when developing
ecasound; precompiled packages require libstdc++
2.10.0 (comes with gcc 2.95.1) or newer
- fixed: few minor fixes to the noisegate effect
- fixed: upon creation, more precision is used to print
effect parameters
190899 (v1.5.1r5)
- fixed: problems with filters
180899 (v1.5.0r5)
- added: ecatools package which now consists of programs
ecatools_normalize, ecatools_fixdc and
ecatools_play - see ecatools(1) man page
- changed: ecasound and qtecasound now have their own
source trees; rest of ecasound is compiled
into the libecasound.so shared library
- changed: to make ecasound relocatable, preset files are now
installed to standard data dir (defaults to
/usr/local/share/ecasound)
- changed: lot of source file name changes
- changed: ALSA support (libasound.so library) is now loaded
dynamically at runtime
- fixed: you had to have yodl installed to to install ecasound
man pages
150899 (v1.4.6r5) -** public release **-
- added: qtecasound - along with some other improvements,
waveform widget now uses cache files to store
wave statistics; for file "somefile.wav", cache
file "somefile.wav.ews" is used
- fixed: reading and writing aiff files works again;
some aiff files created with sox still seem to
cause trouble (might be a problem with
libaudiofile)
- fixed: qtecasound - a nasty mutex bug which caused ecasound
to crash if you tried to use a chainsetup which has
more inputs than chains
120899 (v1.4.5r4):
- added: qtecasound - dialogs for adding, removing and
attaching inputs and outputs
- added: support for null inputs/outputs
- added: effect status is now printed when exiting ecasound
(doesn't affect interactive mode)
- added: if OSS drivers for your soundcard don't support
trigger functions, you can disable these with
configure option "--disable-osstrigger"
- added: -ev effect (analyze sample data) now also tells
how much the analyzed signal can be amplified
without clipping
- added: debug level can now be set in iactive mode with
"debug level" command
- changed: qtecasound - shortcuts a, A and ctrl-a now do
the same thing; applies to all shortcuts
- fixed: adding a chain without a valid output resulted in
hangs when using multithreaded mixmode
- fixed: didn't compile with alsa-lib versions older than 0.3.1
- fixed: "ecasound -h" dumped core
010899 (v1.4.4r4)

- added: qtecasound - adding and deleting chains
- changed: some layout changes
290799 (v1.4.3r4)
- changed: if format supports it, outputs are now opened in
read-write mode; currently supported by .wav,
.cdr and .raw; when you use these as outputs, files
aren't truncated if they exist
- fixed: qtecasound - active chainsetup was always saved even
if some other chainsetup was selected
- fixed: qtecasound - crashed if you changed the active
chainsetup and you had a waveform window open
- fixed: qtecasound - crashed if tried to activate
a invalid chainsetup
- fixed: if you wrote to a output file, its length was
not changed (from ecasound's viewpoint)
270799 (v1.4.2r4)
- fixed: samplebuffer.h still tried to include <soundcard.h>,
which is both not necessary and a wrong place to
look for it; thanks to Torbjorn Tornkvist and
Xavier Hosxe for notifying me
- fixed: qtecasound - using multithreaded mixmode, changing
chainsetups on the fly caused a lot of problems
- fixed: qtecasound - shortcut keys didn't work with CLI
270799 (v1.4.1r4)
- added: qtecasound - chain widget now monitors effect
parameters
- added: qtecasound - support for double clicks and return
presses for various widgets
- added: qtecasound - some new features to the waveform widget
- changed: from now on, interactive mode isn't automatically
enabled, if a realtime input is specified
- changed: names of some functions (I'm trying to be careful
how I use 'new' and 'add', 'load' and 'open', etc
- fixed: qtecasound - waveform widget crashed qtecasound if
the analyzed file had less than 76800 samples
- fixed: if processing was completed and was restarted without
a rewind/setpos, ecasound crashed/hang
- fixed: raised-priority mode was sometimes enabled even
without the -r option
- fixed: qtecasound - when using multithreaded mixmode,
exiting sometimes resulted in core dump or segfault
250799 (v1.4.0r4)
- added: qtecasound - waveform widget; graphical representation
for input/output objects
- added: qtecasound - chain widget; view chain status
- added: qtecasound - chainsetup widget; status of input,
output and chain objects, enable/disable chains
- added: qtecasound - session-setup widget; load and save
chainsetups, create new ones, etc
- changed: can now be started without a valid chainsetup if
interactive mode is enabled
- fixed: *serious bug* if end of input was reached,
that input remained silent until ecasound was
restarted (has been broken since 1.3.0r3)
240799 (v1.3.3r4)
- added: -n option, sets chainsetup's name
230799 (v1.3.2r4)
- added: a new compressor - thanks for Viktor Endersz for
sending it to me and John S. Dyson for coding it;
it really works like a dream! (option -eca)
- fixed: some fixes to my old compressor (now that we
have a better one, this should be used only if
you really want brutal results :))
- fixed: due to some changes in ALSA libs, ecasound
wouldn't compile with ALSA versions >0.3.2;
haven't tested it, but should now work with both
new and old ALSA libs
200799 (v1.3.1r4) -** public release **-
- fixed: delay effect was broken; while fixing this I also
added a new surround mode, 2 = stereo-spread
- fixed: more bugs with ALSA and OSS input routines;
did some multitrack recording with both of them
and got suprisingly good results (it seems that
finding the optimal buffer size is the key to success)
190799 (v1.3.0r3)
- added: support for sessions and chainsetups; now you can
store the whole runtime setup to an ascii file and
load it back; the syntax used is exactly the
same as the command line syntax so editing these
saved chainsetup files is easy
- added: "-s[:]filename" command line option for loading
chainsetup files
- added: "load filename" and "save filename" commands to
the interactive-mode (for chainsetups)
- added: support for libaudiofile (SGI audiofile) library;
new file formats: .aiff, .au and .snd; (linking to
audiofile can be prevented with --disable-audiofile
option to the configure script)

- added: support for raw/headerless (.raw) input/output files
- added: support for using standard system input and output
streams (-i:stdin, -o:stdout)
- added: finished the man pages, all important options and
features should now be covered
- fixed: file name ending with a upper-case extension
wasn't recognised
- fixed: when using multithreaded mixmode with complex setups,
threads sometimes went out of sync causing strange
behaviour
- changed: size of sample buffer objects can now be changed
on-the-fly (output files are not aligned to
buffersize anymore) -> this makes ecasound more
usable as a format conversion tool
- changed: compressor wasn't working, decided to code
a new one (still experimental but works better
than the last one)
140799 (v1.2.3r3)
- added: support for .mp2 files
- fixed: still some bugs in selecting mixmode
- fixed: automatic stereo-mono conversion wasn't working
at all (as all chains are internally stereo, this
occured everytime you specified a mono output, even
if the input was mono, too)
130799 (v1.2.2r3)
- added: ALSA devices can now also be opened by specifying
the actual device name (/dev/snd/pcm...)
- changed: default output is now always attached to chain 'all'
- fixed: start/stop/forward/rewind with ALSA-output sometimes
resulted in loud crackle
- fixed: some bugs in the position slider of qtecasound
- fixed: 'noise-gate-mono' effect was rewritten as it didn't
seem to work very well
120799 (v1.2.1r3) -** public release **-
- added: 'make install' now creates /etc/ecasound directory
and copies all the configuration/preset files
to this directory (existing files/dirs are skipped)
- added: lots of crash-guards to command line parsing
- added: frequently-asked-questions file (both txt and html)
- added: new options to the configure script: --disable-alsa,
--disable-oss and --disable-qt
- fixed: bugs in mixmode multithreaded-iactive (crashed
pretty much everytime)
- fixed: estatus output was sometimes pretty messy
110799 (v1.2.0r2)
- added: support for ALSA input/output
- added: a lot of new documentation to the man pages
- added: new configurable options to ~/.ecasoundrc
(default-buffersize, default-to-interactive-mode,
default-to-raisepriority)
- added: finally implemented the 'help' command in
the interactive-mode; also added a prompt, which
should help a bit :)
- added: autoconf and automake additions; now qtecasound is
compiled only if qt library is found, OSS and
ALSA modules are compiled if the necessary
headers and libraries are available
- added: support for single-chain effect presets (-ps command
line option)
- fixed: bugs with OSS-input (device was sometimes closed
multiple times resulting in core dumps)
- fixed: auto-runmode used 'simple-iactive' mixmode
although iactive-mode wasn't set
- fixed: looping wasn't working properly
- fixed: -m option wasn't working
- removed: simple filter effect (not really useful)
- removed: 'Waiting for the processing thread'
messagebox (qtecasound)
100799 (v1.1.8r2)
- fixed: more synchronisation bugs
050799 (v1.1.6r2)
- added: rewrote the man-pages using Yodl; now they're
also available in HTML-format
- fixed: OSS-output module used a non-standard location
for soundcard.h (noticed by D.Phillips)
010799 (v1.1.5r2) -** public release **-
- tested: did some real recording and mixing work with this
version and after a few fixes, everything seems
to work ok
- added: now checks whether a chainop supports parameter
controlling or not
- added: a lot of new documentation (especially to
'Documentation/examples.html')
- fixed: chain 'all' wasn't working properly
- fixed: multitrack chain synchronization was broken; should
now work even with complex setups
- fixed: a serious bug in OSS-input: ecasound always threw
an "read-error" exception when trying to read from
OSS input
- fixed: analyze effect (-ev) output didn't work
300699 (v1.1.4r1) -** public release **-
- notice! first release; should be considered beta
- fixed: if mp3 files had white-spaces in their filenames,
filenames weren't interpreted correctly

- support for GNU autoconf and automake
- added some new command line shortcuts
- qtecasound: added a position slider widget (displays and
enables to change current position)

they will reappear in the "Chain Setup"
window (still under work)
160699 (v1.0.8r0)
- mp3 output support (using lame)
150699 (v1.0.7r0)
- fixed: waveform -output now works with all inputs
(for instance showing mp3 waveforms is now possible)
- routines for interfacing with mpg123 recoded;
a lot more stable than before
- qtecasound now uses the new qt library (v2.0beta2)
- support for various controllers (sine oscillator, MIDI
cc-controllers, generic oscillator etc)
- fixed: when ecasound was stopped with ctrl-c or kill,
proper cleanup wasn't done
100699 (v1.0.6r0)
- a new wave-form view
080699 (v1.0.5r0)
- multitrack-mode sync-routines rewritten and tested
- various mixmode bugs fixed
040699 (v1.0.4r0)
- simple graphical vu-meters added to test the new io-system
030699 (v1.0.3r0):
- multithread-io mode: one chain can be processed and mixed
while waiting for getting data from other chains
020699 (v1.0.2r0):
- a better way to deal with system endianess
- new chain-operator routines; unless there are no no chainops,
signal is always put through a clip control routine which
ensures that all sample values fit the value range
010699 (v1.0.1r0)

- support for MIDI-controllers
- now uses glibc v2.0 and linuxthread libraries
041098 (v0.70)
- began to upkeep this history file
- fixing the gate-functions
---
1998: - changed development platform from Os/2 to Linux
1997-98: - complete rewrite in C++; name changed from "wavstat" to "ecasound"
1995-97: - started working with this project; original program
was called "wavstat" and it basicly was just
a very simple command line DSP util (running under Os/2)
