* added support for gig v3 multi-file format

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