12 * 6th July 1998 -- Fixed an initialisation problem when
13 slScheduler was not a static/global.
15 Tom Knienieder's port to SGI/IRIX is now
16 working, documentation updated to reflect that.
18 * 16th June 1998 -- Added some slPortability.h fixes for
19 FreeBSD and the Cygnus WIN32 compiler.
22 * 14th June 1998 -- Tom Knienieder's port to OpenBSD is now
23 working, documentation updated to reflect that.
24 Tom's improved Makefiles included, also some
25 example sound samples that were accidentally
26 left out of the release are now present.
27 A couple of typo's in the WIN32 section
28 have been fixed. The top level Makefile
29 now requires you to type 'make linux',
30 'make win' or 'make openbsd'.
32 * 13th June 1998 -- Tom Knienieder's port to WIN32 engine is now
33 working, documentation updated to reflect that
34 revised status. Some default constructor parameters
35 have changed, slDSP no longer supports setRate/setBps/setStereo.
36 You now have to delete the slDSP and recreate it with
37 new parameters. This makes porting a little easier.
38 'sound_test' renamed 'example'.
40 * 7th June 1998 -- Volume envelopes (and inverse volume envelopes)
41 now work correctly. Pan envelopes won't work
42 until stereo is implemented. Pitch and filter
43 envelopes turn out to be a major pain to implement
44 with the present slSceduler/slSamplePlayer interface,
45 so some significant internal changes are to be
48 Changed the CHANGES file to be in reverse
51 This version is officially SL v0.3 (beta)
53 * 3rd June 1998 -- Moved sample program and it's data files into
54 'example', moved documents into 'doc' and sources
55 into 'src'. Final library goes into 'lib'.
57 The entire preempting mechanism was broken -
60 Added a callback mechanism that allows
61 applications to know when a sound
62 loops, finishes playing, is pre-empted, etc.
64 New mechanisms added to stop/pause/resume a
67 All the documentation - and some of the code -
68 for slEnvelopes has been added, they don't
69 work yet - so don't bother with them for now.
71 Made some code a little more bullet-proof.
72 slSample's are now reference-counted so you
73 can't accidentally delete one while it's
74 playing without getting a FATAL error.
76 * 2nd June 1998 -- Fixed bug in initialisation that prevented SL
77 from functioning correctly in the case were there
78 is no sound card present.
80 This version is officially SL v0.2 (beta)
82 * 1st June 1998 -- Split library into two parts - libsm and
83 libsl. libsm contains only the Mixer class
84 since it is likely to be hard to port to
85 a lot of non-OSS systems - and most programs
86 won't need it anyway. Hence the documentation
87 has blossomed into three files and all the
88 'slMixer' references have turned into 'smMixer'.
89 Also, I finally got a hold of the OSS documentation,
90 which is a lot more complete - and straightened
91 me out on a few points. slDSP has changed
92 (internally) somewhat as a result and in particular,
93 you can no longer mess with the sampling rate,
94 stereo and bps settings after the slDSP or
95 slScheduler has been created. This also allows the
96 scheduler to enforce it's rule about only mono/8bps
99 I also added an 'autoMatch' function to the slSample
100 class to automagically match incoming samples to the
101 current slDSP/slScheduler. This makes using the library
102 a lot less painful and error-prone.
104 This version is officially SL v0.1 (beta)
106 We need a better name!
108 * 30th May 1998 -- Almost total rewrite, library can now
109 play multiple sounds without interruption,
110 supports '.WAV' and '.AU' file formats as
111 well as raw binary files. Able to copy with
112 much shorter safetyMargin on sound buffers,
113 and play without using the 'stop' call.
114 All class and external symbols now begin
115 with 'sl' or 'SL'. HTML documentation now
118 * 27th May 1998 -- First hack
