*** ecasound - user visible changes (NEWS)    (last edited: 231199) ***
-----------------------------------------------------------------------

About the version numbers... "vx.y.zRt" :

  x   = major version - changes in design and public interfaces 
  y.z = minor version - bug fixes, new features and new functionality
		        to current major version
  R   = 'r' or 'd'    - 'r' means that this a public (stable) release
		        while development versions are marked with 'd'
  t   = public release  - changes only when a stable version is 
		          officially released

-----------------------------------------------------------------------

Last officially released version is -*> v1.6.7r7 <*-

251199 (v1.6.7r7)  -** public release **-
	- changed: some not-so-important runtime info (opening and 
		   closing devices, etc) is now considered to be 
		   debug info and is not printed by default
	- changed: position is printed as a floating-point value
	- fixed: qtecasound - lots of bugs
221199 (v1.6.6d6)
	- fixed: cs-save and cs-save-as didn't work as expected
	- fixed: cs-load didn't work properly
221199 (v1.6.5d6)
	- added: safety-checks to prevent users from connecting
	         invalid chainsetups
	- added: underlines are accepted in ia-mode commands
	- fixed: problems with -ev
	- fixed: minor bugs in audvvio object positioning
191199 (v1.6.4d6)
	- added: -erc - channel copy (one-to-one) and
		 -erm - mix all channels (all-to-one) ; these are 
		 meant for handling multichannel files
	- added: -y option - set starting position for last specified
		 input/output
	- added: -t option - set processing time in seconds (makes 
		 multitrack cut&paste possible when used with -y)
	- added: -tl option - enable looping (see -y and -t)
	- added: ia-mode: cs-length (like -t), cs-loop (like -tl)
	- added: you can now pass additional options to external 
	         programs (mpg123, lame, mikmod), specified 
	 	 in ~/.ecasoundrc 
	- changed: mute + unmute -> mute (on/off toggle)
	- changed: bypass-enable + bypass-disable -> bypass
	- changed: minor changes in ~/.ecasoundrc format (see 
		   ecasoundrc(5))
	- fixed: tried to reconnect invalid chainsetups
	- fixed: global forward and rewind weren't working
	- fixed: dumped core if number of delays (-etd) was changed
		 during processing
	- fixed: gates are working once again
	- fixed: minor bugs in output mixing
	- fixed: -s option wasn't working properly
	- fixed: 8<->16bit conversion
  	- fixed: bugs in AIFF output
161199 (v1.6.3d6)
	- added: new ia-mode commands: aio-forward, aio-rewind, 
		 aio-setpos, aio-index-select and aio-wave-edit 
		 (load currently selected audio object into an
		 external wave editor)
	- added: support for using tracker modules as input 
	         sources - uses mikmod (mikmod 3.1.6 + libmikmod 
		 3.1.7 or newer required)
	- changed: cleaned up the audio object interface
	- changed: -f parameter format has changed - instead of 
		   bits, sample type is now specified as a formatted
		   string ("u8", "s16_le", "s24_le" and so on)
	- changed: in precise-sample-rate mode, removed all implicit 
		   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
		   more powerful as client programs can have direct
	           access to chainops they've added (see 
		   eca-controller.h for details)
101199 (v1.6.1d6) 
	- added: most interactive-mode commands are now implemented
	- added: new ia-mode commands: c-mute, c-unmute, c-process,
		 c-select-all, cs-save-as, 
	- added: documentation for nearly all implemented ia-mode
		 commands, see ecasound-aim(1)
	- changes: major changes in RPM-packaging
	- fixed: a very nasty bug in dynamic ALSA-support
	- fixed: some effects caused core dumps (bug in the sbuf
		 iterator routines)
	- fixed: many minor bug fixes
	- removed: ia-mode commands: exec, end
081199 (v1.6.0d6) 
	- added: iactive mode now uses GNU readline for user input 
		 - command-line editing, command history and command 
		 completion (use .inputrc for configuring)
	- added: 30-40 new interactive-mode commands
	- added: ecasound-iam(1) manual page - interactive mode 
		 documentation
	- added: ecasound user's guide and programmer's guide
	- added: 'default-to-precise-sample-rates' to ecasoundrc -
		 whether to ignore sample rate differences (and 
	         possibly avoid resampling), affects OSS-devices,
	         defaults to 'false'
	- added: -z:psr option (see above)
	- changed: reimplemented signal handling using POSIX 
	           signal handlers (ANSI interface was used before)
	- changed: divided all the bigger modules into smaller 
		   classes and files (these big modules were
		   causing lots of compiler and resource problems)
	- changed: major internal changes (multichannel chain operators,
		   improved mixing algorithms, etc)
	- changed: rewritten mp3-support (still using mpg123 and lame)
	- changed: lots of changes in handling external resources
	           (wave and text editors, mpg123 and lame parameters,
 		   etc.) - see 'man ecasoundrc'
	- removed: looping (interactive-mode loop commands)
	- removed: 'sfx' command (iactive-mode)
011099 (v1.5.16d6)

		 from now on logged to libecasound/ChangeLog
	- fixed: errors in -kf documentation
270999 (v1.5.15d6)

		   to improve ecasound's performance with
		   complex setups
	- fixed: "-ev" max-amplitude wasn't reseted
	- fixed: some finetuning of ALSA buffer handling
210999 (v1.5.14d6)
	- notice: from now on development versions will be marked 
		  with a 'd' in the version number
	- added: configure check for libdl library
	- added: "-eac:amp-%,channel" channel amplify
	- changed: "-ea" to "-eaw", amplify with clipping control
	- changed: "-eas" to "-ea", normal amplify
180999 (v1.5.13r6)
	- added: -sr:srate option - set chainsetup sample rate
	- added: 'default-samplerate' to ~/.ecasoundrc
	- fixed: problems with OSS es1370 drivers (thanks to Billy

140999 (v1.5.12r6)  -** public release **-
	- fixed: problems with libaudiofile (.aiff and .au/.snd
	         support)
	- fixed: extra noise when upsampling
	- fixed: qtecasound - chainsetup's name was changed to

	- fixed: qtecasound - conflict with Qt-libs when 
		 stopping processing (resulted in abort) 
120999 (v1.5.11r5)
	- added: ldconfig is now always run after (un)install of 
	         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)
	- fixed: ecasound tried to use ALSA headers even though 
	         --disable-alsa was given (eca-alsa-dyn.h and
	         eca-midi.h)
	- fixed: audiofx_compressor.h tried to include obsolete
	         error.h header file
	- fixed: pan effect (-epp) decreased overall volume level
	- fixed: fake-stereo effect (-etf) wasn't working properly
	- fixed: "make install" created (prefix)/share/ecasound
		 with permission mode 644 (only root could access

	- fixed: some problems with effect option parsing
	- removed: simple lowpass filter (-ef2)
070999 (v1.5.10r5)
	- added: qtecasound - file dialogs now remember the current
		 directory
	- added: a much more elegant system for dynamically loading 
		 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: in some rare cases, engine was started in interactive 
		 mixmode while the interface was in passive mode 
	         (-> program started but didn't do anything)
030999 (v1.5.8r5)
	- added: '!' shortcut to all windows (keyboard focus to 
		 control panel)
	- changed: some Makefile changes for excluding static
		   ecasound libraries from the binary dist packages
		   (managed to shrink binary-rpms by nearly a 1MB!)
	- fixed: qtecasound - shortcut-key fixes in chainsetup window
	- 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 - now asks for a name when adding chainsetups
	- 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: -q option (quiet mode), disables all output
	- 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
250699 (v1.1.3r0)
	- more bug fixes
	- tested rpm-packaging and seemed to work ok

       	- qtecasound: added a not-implemented message screen! ;)
180699 (v1.1.0r0)
       	- all major features of ecasound v0.9.x and earlier are 
          now implemented to the new program design 
       	- support for gates (time crop gate and threshold gate
          implemented)
       	- support for ~/.ecasoundrc configuration file
       	- 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)
       	- qtecasound: removed waveform and volume meter widgets;
		      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

       	- 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)
        - fixed a _lot_ of bugs
310599 (v1.0.0r0)

        - 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)
