\**********************************************/
* 28th Sept 1889 -- Fixed a bug associated with exiting the
program with sounds still playing.
Fixed a bug associated with using the
package in the absence of a sound card.
Added a new member function "working"
which is the opposite of "not_working",
(as demanded by a bunch of rabid optimists)!
Fixed a couple of typo's in the manual.
* 23rd Sept 1998 -- The Good News: Finally got around to
getting the pitch envelope working. (Hooray)
The Bad News: This costs quite a bit in
performance - and it was a MAJOR rewrite
of significant parts of the internals,
so we may need some bug fixes.
This version is 0.5
* 7th July 1998 -- Fixed some error checking in slSample.cxx and
a missing declaration in sl.h
* 6th July 1998 -- Fixed an initialisation problem when
slScheduler was not a static/global.
Tom Knienieder's port to SGI/IRIX is now
working, documentation updated to reflect that.
* 16th June 1998 -- Added some slPortability.h fixes for
FreeBSD and the Cygnus WIN32 compiler.
Many thanks to Curt.
* 14th June 1998 -- Tom Knienieder's port to OpenBSD is now
working, documentation updated to reflect that.
Tom's improved Makefiles included, also some
example sound samples that were accidentally
left out of the release are now present.
A couple of typo's in the WIN32 section
have been fixed. The top level Makefile
now requires you to type 'make linux',
'make win' or 'make openbsd'.
* 13th June 1998 -- Tom Knienieder's port to WIN32 engine is now
working, documentation updated to reflect that
revised status. Some default constructor parameters
have changed, slDSP no longer supports setRate/setBps/setStereo.
You now have to delete the slDSP and recreate it with
new parameters. This makes porting a little easier.
'sound_test' renamed 'example'.
* 7th June 1998 -- Volume envelopes (and inverse volume envelopes)
now work correctly. Pan envelopes won't work
until stereo is implemented. Pitch and filter
envelopes turn out to be a major pain to implement
with the present slSceduler/slSamplePlayer interface,
so some significant internal changes are to be
expected.
Changed the CHANGES file to be in reverse
chronological order.
This version is officially SL v0.3 (beta)
* 3rd June 1998 -- Moved sample program and it's data files into
'example', moved documents into 'doc' and sources
into 'src'. Final library goes into 'lib'.
The entire preempting mechanism was broken -
now it's fixed.
Added a callback mechanism that allows
applications to know when a sound
loops, finishes playing, is pre-empted, etc.
New mechanisms added to stop/pause/resume a
playing sample.
All the documentation - and some of the code -
for slEnvelopes has been added, they don't
work yet - so don't bother with them for now.
Made some code a little more bullet-proof.
slSample's are now reference-counted so you
can't accidentally delete one while it's
playing without getting a FATAL error.
* 2nd June 1998 -- Fixed bug in initialisation that prevented SL
from functioning correctly in the case were there
is no sound card present.
This version is officially SL v0.2 (beta)
* 1st June 1998 -- Split library into two parts - libsm and
libsl. libsm contains only the Mixer class
since it is likely to be hard to port to
a lot of non-OSS systems - and most programs
won't need it anyway. Hence the documentation
has blossomed into three files and all the
'slMixer' references have turned into 'smMixer'.
Also, I finally got a hold of the OSS documentation,
which is a lot more complete - and straightened
me out on a few points. slDSP has changed
(internally) somewhat as a result and in particular,
you can no longer mess with the sampling rate,
stereo and bps settings after the slDSP or
slScheduler has been created. This also allows the
scheduler to enforce it's rule about only mono/8bps
operations.
I also added an 'autoMatch' function to the slSample
class to automagically match incoming samples to the
current slDSP/slScheduler. This makes using the library
a lot less painful and error-prone.
This version is officially SL v0.1 (beta)
We need a better name!
* 30th May 1998 -- Almost total rewrite, library can now
play multiple sounds without interruption,
supports '.WAV' and '.AU' file formats as
well as raw binary files. Able to copy with
much shorter safetyMargin on sound buffers,
and play without using the 'stop' call.
All class and external symbols now begin
with 'sl' or 'SL'. HTML documentation now
available.
* 27th May 1998 -- First hack
