12 * 28th Sept 1889 -- Fixed a bug associated with exiting the
13 program with sounds still playing.
14 Fixed a bug associated with using the
15 package in the absence of a sound card.
16 Added a new member function "working"
17 which is the opposite of "not_working",
18 (as demanded by a bunch of rabid optimists)!
19 Fixed a couple of typo's in the manual.
21 * 23rd Sept 1998 -- The Good News: Finally got around to
22 getting the pitch envelope working. (Hooray)
23 The Bad News: This costs quite a bit in
24 performance - and it was a MAJOR rewrite
25 of significant parts of the internals,
26 so we may need some bug fixes.
29 * 7th July 1998 -- Fixed some error checking in slSample.cxx and
30 a missing declaration in sl.h
32 * 6th July 1998 -- Fixed an initialisation problem when
33 slScheduler was not a static/global.
35 Tom Knienieder's port to SGI/IRIX is now
36 working, documentation updated to reflect that.
38 * 16th June 1998 -- Added some slPortability.h fixes for
39 FreeBSD and the Cygnus WIN32 compiler.
42 * 14th June 1998 -- Tom Knienieder's port to OpenBSD is now
43 working, documentation updated to reflect that.
44 Tom's improved Makefiles included, also some
45 example sound samples that were accidentally
46 left out of the release are now present.
47 A couple of typo's in the WIN32 section
48 have been fixed. The top level Makefile
49 now requires you to type 'make linux',
50 'make win' or 'make openbsd'.
52 * 13th June 1998 -- Tom Knienieder's port to WIN32 engine is now
53 working, documentation updated to reflect that
54 revised status. Some default constructor parameters
55 have changed, slDSP no longer supports setRate/setBps/setStereo.
56 You now have to delete the slDSP and recreate it with
57 new parameters. This makes porting a little easier.
58 'sound_test' renamed 'example'.
60 * 7th June 1998 -- Volume envelopes (and inverse volume envelopes)
61 now work correctly. Pan envelopes won't work
62 until stereo is implemented. Pitch and filter
63 envelopes turn out to be a major pain to implement
64 with the present slSceduler/slSamplePlayer interface,
65 so some significant internal changes are to be
68 Changed the CHANGES file to be in reverse
71 This version is officially SL v0.3 (beta)
73 * 3rd June 1998 -- Moved sample program and it's data files into
74 'example', moved documents into 'doc' and sources
75 into 'src'. Final library goes into 'lib'.
77 The entire preempting mechanism was broken -
80 Added a callback mechanism that allows
81 applications to know when a sound
82 loops, finishes playing, is pre-empted, etc.
84 New mechanisms added to stop/pause/resume a
87 All the documentation - and some of the code -
88 for slEnvelopes has been added, they don't
89 work yet - so don't bother with them for now.
91 Made some code a little more bullet-proof.
92 slSample's are now reference-counted so you
93 can't accidentally delete one while it's
94 playing without getting a FATAL error.
96 * 2nd June 1998 -- Fixed bug in initialisation that prevented SL
97 from functioning correctly in the case were there
98 is no sound card present.
100 This version is officially SL v0.2 (beta)
102 * 1st June 1998 -- Split library into two parts - libsm and
103 libsl. libsm contains only the Mixer class
104 since it is likely to be hard to port to
105 a lot of non-OSS systems - and most programs
106 won't need it anyway. Hence the documentation
107 has blossomed into three files and all the
108 'slMixer' references have turned into 'smMixer'.
109 Also, I finally got a hold of the OSS documentation,
110 which is a lot more complete - and straightened
111 me out on a few points. slDSP has changed
112 (internally) somewhat as a result and in particular,
113 you can no longer mess with the sampling rate,
114 stereo and bps settings after the slDSP or
115 slScheduler has been created. This also allows the
116 scheduler to enforce it's rule about only mono/8bps
119 I also added an 'autoMatch' function to the slSample
120 class to automagically match incoming samples to the
121 current slDSP/slScheduler. This makes using the library
122 a lot less painful and error-prone.
124 This version is officially SL v0.1 (beta)
126 We need a better name!
128 * 30th May 1998 -- Almost total rewrite, library can now
129 play multiple sounds without interruption,
130 supports '.WAV' and '.AU' file formats as
131 well as raw binary files. Able to copy with
132 much shorter safetyMargin on sound buffers,
133 and play without using the 'stop' call.
134 All class and external symbols now begin
135 with 'sl' or 'SL'. HTML documentation now
138 * 27th May 1998 -- First hack
