preparations for release 2.0.0

1 Version 2.0.0 (9 May 2005)
2
3 * packaging changes:
4 - fixed conditional linkage of either libsndfile or libaudiofile
5 (if none of the two exist, configure script will abort)
6 - man pages are now auto generated with the correct libgig version
7
8 * src/gig.cpp, src/gig.h:
9 - experimental support for Gigasampler v3 format;
10 64 bit file offsets are truncated to 32 bit, 24 bit samples are
11 truncated to 16 bit, up to 8 dimensions are read, additional
12 articulation informations are ignored at the moment
13 (patch by Andreas Persson)
14 - added some file format compatibility checks
15 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
16 never used, because the necessary check was made before
17 initialization)
18 - fixed crossfade points order (structure for big endian and little
19 endian systems was interchanged)
20 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
21 - fixed crash which occured when patches did not have a sample assigned
22 to their region or dimension region (patch by Andreas Persson)
23 - support for compressed mono samples
24 - experimental support for compressed 24 bit samples
25 - fixed decompression on big-endian CPUs
26 - fixed decompression bug that truncated the last block of samples
27 - external decompression buffers can now be used for streaming samples
28 to avoid race conditions in case of multiple streaming threads
29 - added pre-calculated sample attenuation parameter
30 - added v3 "random" and "round robin" dimensions
31 - implemented progress indicator callback mechanism for loading
32 instruments and samples
33 - added functions libraryName() and libraryVersion()
34
35 * src/DLS.cpp, src/DLS.h:
36 - fixed File constructor which caused variable File::Instruments always
37 to be zero
38 - added functions libraryName() and libraryVersion()
39
40 * src/RIFF.cpp, src/RIFF.h:
41 - fixed method List::LoadSubChunks() which did not restore the original
42 position within the body of the given list chunk
43 - added functions libraryName() and libraryVersion()
44
45 * src/rifftree.cpp:
46 - added command line switch -v to show rifftree's revision and the used
47 libgig version
48
49 * src/dlsdump.cpp:
50 - added command line switch -v to show dlsdump's revision and the used
51 libgig version
52
53 * src/gigdump.cpp:
54 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
55 LoopPlayCount
56 - added command line switch -v to show gigdump's revision and the used
57 libgig version
58
59 * src/gigextract.cpp:
60 - support for compressed mono samples and compressed 24 bit samples
61 - added command line switch -v to show gigextract's revision and the
62 used libgig version
63
64 Version 1.0.0 (26 Nov 2004)
65
66 * packaging changes:
67 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
68 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
69 - fixed man pages automake install rule (which didn't work on Mandrake,
70 SuSE and Fedora)
71 - fixed generation of Doxygen API documentation (now also included in
72 RPM and Debian packages)
73
74 * src/gig.cpp, src/gig.h:
75 - fixed / improved accuracy of all three velocity to volume
76 transformation functions a.k.a. 'nonlinear','linear','special'
77 (patch by Andreas Persson)
78 - denormals are filtered from the velocity to volume tables
79 - bugfix for dimension region switching (wrong handling of the release
80 trigger dimension, no bit range check for dimensions of split type
81 'split_type_bit')
82 - fixed panorama value in DimensionRegion (invalid conversion from
83 signed 7 bit to signed 8 bit)
84 - added class attribute 'Layers' to class 'gig::Region'
85 - symbol prototyping of gig::Region (fixes build failure with qsampler)
86
87 * src/gigextract.cpp:
88 - added support for libsndfile (if libaudiofile and libsndfile are
89 available then libsndfile is preferred)
90
91 * src/gigdump.cpp:
92 - added printout for dimension informations (amount, type, bits, zones)
93 - added printout for velocity response curve parameters
94 - added printout for crossfade definitions
95 - added printout for panorama value for each DimensionRegion
96 - replaced printout of DLS Region layer by printout of amount of
97 Gigasampler layers
98
99 Version 0.7.1 (2 Jul 2004)
100
101 * packaging changes:
102 - added libgig.spec and libgig.pc package configurations for generating
103 Redhat packages
104 - header files included on installation.
105 - autotools-generated files removed from CVS repository.
106 - added support for generating Debian packages
107 - version of shared library can be set in configure.in
108
109 Version 0.7.0 (3 May 2004)
110
111 * general changes:
112 - various big endian specific corrections
113 (successfully tested now on PPC)
114 - minor adjustments to avoid compile errors on some systems
115 (using now pow() instead of powl() and --pedantic g++ compiler switch)
116 - libtoolized the library
117 - added man pages for the command line tools
118 (gigextract, gigdump, dlsdump, rifftree)
119
120 * src/gig.cpp, src/gig.h:
121 - fixed bug in decompression algorithm which caused it not to detect
122 the end of a stream
123 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
124 takes the MIDI key velocity value as an argument and returns the
125 appropriate volume factor (0.0 ... 1.0) for the sample to be played
126 back, the velocity curve transformation functions used for this are
127 only an approximation so far
128 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
129 'Sample::LoopSize' which reflected wrong values
130 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
131 measured in sample points instead of byte offset
132 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
133 'Sample::FineTune'
134 - added class attribute 'Sample::LoopSize'
135 - added method GetInstrument(uint index) to class 'File'
136 - added ReadAndLoop() method to class 'Sample' which is an extension to
137 the normal Read() method to honor the sample's looping information
138 while streaming from disk
139 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
140 'eg2_ctrl_t': replaced this huge enumeration by a structure which
141 reflects the MIDI controller number in case of an ordinary control
142 change controller (this saves a huge switch-case block in the
143 application of the library user)
144 - renamed following attributes in class 'DimensionRegion':
145 'AttenuationContol' -> 'AttenuationController',
146 'InvertAttenuationControl' -> 'InvertAttenuationController',
147 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
148 - minor fix in API documentation for method GetVelocityAttenuation() in
149 class 'DimensionRegion'
150
151 * src/RIFF.cpp, src/RIFF.h:
152 - added additional API documentation
153 - minor fix in Chunk::Read() method (only a minor efficiency issue)
154
155 * src/gigdump.cpp:
156 - added printout of samples' looping informations
157
158 Version 0.6.0 (3 Nov 2003)
159
160 * initial release
