File size: 8247 byte(s)
* fixed the 24 bit decompression, the result should now be exact
  instead of an approximation

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - require automake (>= 1.5) for 'make -f Makefile.cvs'
5 (mandatory for 'dist-bzip2' automake option)
6
7 * src/gig.cpp, src/gig.h:
8 - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
9 the extension files are read automatically when the samples are
10 loaded
11 - fixed the 24 bit decompression, the result should now be exact
12 instead of an approximation
13
14 * src/DLS.cpp, src/DLS.h:
15 - the upper bits of the pool table indices are read (used as
16 extension file numbers for gig v3)
17
18 * src/RIFF.cpp, src/RIFF.h:
19 - the file name is remembered in the RIFF::File object
20
21 Version 2.0.1 (12 Jun 2005)
22
23 * packaging changes:
24 - include debian/ directory on 'make dist'
25 - create a bzip2 tarball on 'make dist'
26
27 * src/gigextract.cpp:
28 - show also version of libsndfile or build version of libaudiofile when
29 using the -v switch
30 - fixed mutual link dependency to libsndfile / libaudiofile
31
32 * src/gig.cpp, src/gig.h:
33 - added DimensionRegion::GetVelocityRelease function
34
35 Version 2.0.0 (9 May 2005)
36
37 * packaging changes:
38 - fixed conditional linkage of either libsndfile or libaudiofile
39 (if none of the two exist, configure script will abort)
40 - man pages are now auto generated with the correct libgig version
41
42 * src/gig.cpp, src/gig.h:
43 - experimental support for Gigasampler v3 format;
44 64 bit file offsets are truncated to 32 bit, 24 bit samples are
45 truncated to 16 bit, up to 8 dimensions are read, additional
46 articulation informations are ignored at the moment
47 (patch by Andreas Persson)
48 - added some file format compatibility checks
49 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
50 never used, because the necessary check was made before
51 initialization)
52 - fixed crossfade points order (structure for big endian and little
53 endian systems was interchanged)
54 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
55 - fixed crash which occured when patches did not have a sample assigned
56 to their region or dimension region (patch by Andreas Persson)
57 - support for compressed mono samples
58 - experimental support for compressed 24 bit samples
59 - fixed decompression on big-endian CPUs
60 - fixed decompression bug that truncated the last block of samples
61 - external decompression buffers can now be used for streaming samples
62 to avoid race conditions in case of multiple streaming threads
63 - added pre-calculated sample attenuation parameter
64 - added v3 "random" and "round robin" dimensions
65 - implemented progress indicator callback mechanism for loading
66 instruments and samples
67 - added functions libraryName() and libraryVersion()
68
69 * src/DLS.cpp, src/DLS.h:
70 - fixed File constructor which caused variable File::Instruments always
71 to be zero
72 - added functions libraryName() and libraryVersion()
73
74 * src/RIFF.cpp, src/RIFF.h:
75 - fixed method List::LoadSubChunks() which did not restore the original
76 position within the body of the given list chunk
77 - added functions libraryName() and libraryVersion()
78
79 * src/rifftree.cpp:
80 - added command line switch -v to show rifftree's revision and the used
81 libgig version
82
83 * src/dlsdump.cpp:
84 - added command line switch -v to show dlsdump's revision and the used
85 libgig version
86
87 * src/gigdump.cpp:
88 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
89 LoopPlayCount
90 - added command line switch -v to show gigdump's revision and the used
91 libgig version
92
93 * src/gigextract.cpp:
94 - support for compressed mono samples and compressed 24 bit samples
95 - added command line switch -v to show gigextract's revision and the
96 used libgig version
97
98 Version 1.0.0 (26 Nov 2004)
99
100 * packaging changes:
101 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
102 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
103 - fixed man pages automake install rule (which didn't work on Mandrake,
104 SuSE and Fedora)
105 - fixed generation of Doxygen API documentation (now also included in
106 RPM and Debian packages)
107
108 * src/gig.cpp, src/gig.h:
109 - fixed / improved accuracy of all three velocity to volume
110 transformation functions a.k.a. 'nonlinear','linear','special'
111 (patch by Andreas Persson)
112 - denormals are filtered from the velocity to volume tables
113 - bugfix for dimension region switching (wrong handling of the release
114 trigger dimension, no bit range check for dimensions of split type
115 'split_type_bit')
116 - fixed panorama value in DimensionRegion (invalid conversion from
117 signed 7 bit to signed 8 bit)
118 - added class attribute 'Layers' to class 'gig::Region'
119 - symbol prototyping of gig::Region (fixes build failure with qsampler)
120
121 * src/gigextract.cpp:
122 - added support for libsndfile (if libaudiofile and libsndfile are
123 available then libsndfile is preferred)
124
125 * src/gigdump.cpp:
126 - added printout for dimension informations (amount, type, bits, zones)
127 - added printout for velocity response curve parameters
128 - added printout for crossfade definitions
129 - added printout for panorama value for each DimensionRegion
130 - replaced printout of DLS Region layer by printout of amount of
131 Gigasampler layers
132
133 Version 0.7.1 (2 Jul 2004)
134
135 * packaging changes:
136 - added libgig.spec and libgig.pc package configurations for generating
137 Redhat packages
138 - header files included on installation.
139 - autotools-generated files removed from CVS repository.
140 - added support for generating Debian packages
141 - version of shared library can be set in configure.in
142
143 Version 0.7.0 (3 May 2004)
144
145 * general changes:
146 - various big endian specific corrections
147 (successfully tested now on PPC)
148 - minor adjustments to avoid compile errors on some systems
149 (using now pow() instead of powl() and --pedantic g++ compiler switch)
150 - libtoolized the library
151 - added man pages for the command line tools
152 (gigextract, gigdump, dlsdump, rifftree)
153
154 * src/gig.cpp, src/gig.h:
155 - fixed bug in decompression algorithm which caused it not to detect
156 the end of a stream
157 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
158 takes the MIDI key velocity value as an argument and returns the
159 appropriate volume factor (0.0 ... 1.0) for the sample to be played
160 back, the velocity curve transformation functions used for this are
161 only an approximation so far
162 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
163 'Sample::LoopSize' which reflected wrong values
164 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
165 measured in sample points instead of byte offset
166 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
167 'Sample::FineTune'
168 - added class attribute 'Sample::LoopSize'
169 - added method GetInstrument(uint index) to class 'File'
170 - added ReadAndLoop() method to class 'Sample' which is an extension to
171 the normal Read() method to honor the sample's looping information
172 while streaming from disk
173 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
174 'eg2_ctrl_t': replaced this huge enumeration by a structure which
175 reflects the MIDI controller number in case of an ordinary control
176 change controller (this saves a huge switch-case block in the
177 application of the library user)
178 - renamed following attributes in class 'DimensionRegion':
179 'AttenuationContol' -> 'AttenuationController',
180 'InvertAttenuationControl' -> 'InvertAttenuationController',
181 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
182 - minor fix in API documentation for method GetVelocityAttenuation() in
183 class 'DimensionRegion'
184
185 * src/RIFF.cpp, src/RIFF.h:
186 - added additional API documentation
187 - minor fix in Chunk::Read() method (only a minor efficiency issue)
188
189 * src/gigdump.cpp:
190 - added printout of samples' looping informations
191
192 Version 0.6.0 (3 Nov 2003)
193
194 * initial release
