* fixed the 24 bit decompression, the result should now be exact
  instead of an approximation

1 schoenebeck 652 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 persson 666 * 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 persson 695 - fixed the 24 bit decompression, the result should now be exact
12     instead of an approximation
13 persson 666
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 schoenebeck 632 Version 2.0.1 (12 Jun 2005)
22 schoenebeck 549
23 schoenebeck 634 * packaging changes:
24     - include debian/ directory on 'make dist'
25     - create a bzip2 tarball on 'make dist'
26    
27 schoenebeck 549 * src/gigextract.cpp:
28     - show also version of libsndfile or build version of libaudiofile when
29     using the -v switch
30 schoenebeck 608 - fixed mutual link dependency to libsndfile / libaudiofile
31 schoenebeck 549
32 persson 613 * src/gig.cpp, src/gig.h:
33     - added DimensionRegion::GetVelocityRelease function
34    
35 schoenebeck 530 Version 2.0.0 (9 May 2005)
36 schoenebeck 317
37 schoenebeck 383 * packaging changes:
38     - fixed conditional linkage of either libsndfile or libaudiofile
39     (if none of the two exist, configure script will abort)
40 schoenebeck 518 - man pages are now auto generated with the correct libgig version
41 schoenebeck 383
42 schoenebeck 317 * 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 schoenebeck 347 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 schoenebeck 317 - added some file format compatibility checks
49 schoenebeck 345 - 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 schoenebeck 355 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
55 schoenebeck 352 - fixed crash which occured when patches did not have a sample assigned

62     to avoid race conditions in case of multiple streaming threads
63 persson 406 - added pre-calculated sample attenuation parameter
64 persson 437 - added v3 "random" and "round robin" dimensions
65 schoenebeck 515 - implemented progress indicator callback mechanism for loading
66     instruments and samples
67 schoenebeck 518 - added functions libraryName() and libraryVersion()
68 schoenebeck 317
69 schoenebeck 518 * src/DLS.cpp, src/DLS.h:

76     position within the body of the given list chunk
77 schoenebeck 518 - added functions libraryName() and libraryVersion()
78 schoenebeck 515

97 persson 365
98 schoenebeck 315 Version 1.0.0 (26 Nov 2004)
99 schoenebeck 196
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 schoenebeck 315 - 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

107 schoenebeck 196
108 schoenebeck 231 * src/gig.cpp, src/gig.h:

110 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
111     (patch by Andreas Persson)
112 schoenebeck 231 - denormals are filtered from the velocity to volume tables
113 schoenebeck 241 - 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 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
117     signed 7 bit to signed 8 bit)
118 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
119 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
120 schoenebeck 231
121 schoenebeck 220 * src/gigextract.cpp:
122     - added support for libsndfile (if libaudiofile and libsndfile are
123     available then libsndfile is preferred)
124    
125 schoenebeck 229 * src/gigdump.cpp:
126     - added printout for dimension informations (amount, type, bits, zones)
127 schoenebeck 231 - added printout for velocity response curve parameters
128 schoenebeck 235 - added printout for crossfade definitions
129 schoenebeck 269 - added printout for panorama value for each DimensionRegion
130 schoenebeck 282 - replaced printout of DLS Region layer by printout of amount of
131     Gigasampler layers
132 schoenebeck 229
133 capela 168 Version 0.7.1 (2 Jul 2004)
134    
135     * packaging changes:
136 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
137     Redhat packages
138 capela 168 - header files included on installation.
139     - autotools-generated files removed from CVS repository.
140 schoenebeck 186 - added support for generating Debian packages
141     - version of shared library can be set in configure.in
142    
143 schoenebeck 58 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 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
193    
194     * initial release
