|
|
|
|
* 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
|
|
