Revision 518 - (show annotations) (download)
Sun May 8 16:19:34 2005 UTC (18 years, 10 months ago) by schoenebeck
File size: 7194 byte(s)
* added functions libraryName() and libraryVersion() to each of the three
  library units (RIFF,DLS,gig)
* all tools now offer a command line switch -v to show the tools revision
  and the used libgig version
* man pages are now auto generated with the correct libgig version

1 Version CVS HEAD (?)
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 and FineTune
55 - added output of Gain and SampleStartOffset
56 - added output of LoopPlayCount
57 - added command line switch -v to show gigdump's revision and the used
58 libgig version
59
60 * src/gigextract.cpp:
61 - support for compressed mono samples and compressed 24 bit samples
62 - added command line switch -v to show gigextract's revision and the
63 used libgig version
64
65 Version 1.0.0 (26 Nov 2004)
66
67 * packaging changes:
68 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
69 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
70 - fixed man pages automake install rule (which didn't work on Mandrake,
71 SuSE and Fedora)
72 - fixed generation of Doxygen API documentation (now also included in
73 RPM and Debian packages)
74
75 * src/gig.cpp, src/gig.h:
76 - fixed / improved accuracy of all three velocity to volume
77 transformation functions a.k.a. 'nonlinear','linear','special'
78 (patch by Andreas Persson)
79 - denormals are filtered from the velocity to volume tables
80 - bugfix for dimension region switching (wrong handling of the release
81 trigger dimension, no bit range check for dimensions of split type
82 'split_type_bit')
83 - fixed panorama value in DimensionRegion (invalid conversion from
84 signed 7 bit to signed 8 bit)
85 - added class attribute 'Layers' to class 'gig::Region'
86 - symbol prototyping of gig::Region (fixes build failure with qsampler)
87
88 * src/gigextract.cpp:
89 - added support for libsndfile (if libaudiofile and libsndfile are
90 available then libsndfile is preferred)
91
92 * src/gigdump.cpp:
93 - added printout for dimension informations (amount, type, bits, zones)
94 - added printout for velocity response curve parameters
95 - added printout for crossfade definitions
96 - added printout for panorama value for each DimensionRegion
97 - replaced printout of DLS Region layer by printout of amount of
98 Gigasampler layers
99
100 Version 0.7.1 (2 Jul 2004)
101
102 * packaging changes:
103 - added libgig.spec and libgig.pc package configurations for generating
104 Redhat packages
105 - header files included on installation.
106 - autotools-generated files removed from CVS repository.
107 - added support for generating Debian packages
108 - version of shared library can be set in configure.in
109
110 Version 0.7.0 (3 May 2004)
111
112 * general changes:
113 - various big endian specific corrections
114 (successfully tested now on PPC)
115 - minor adjustments to avoid compile errors on some systems
116 (using now pow() instead of powl() and --pedantic g++ compiler switch)
117 - libtoolized the library
118 - added man pages for the command line tools
119 (gigextract, gigdump, dlsdump, rifftree)
120
121 * src/gig.cpp, src/gig.h:
122 - fixed bug in decompression algorithm which caused it not to detect
123 the end of a stream
124 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
125 takes the MIDI key velocity value as an argument and returns the
126 appropriate volume factor (0.0 ... 1.0) for the sample to be played
127 back, the velocity curve transformation functions used for this are
128 only an approximation so far
129 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
130 'Sample::LoopSize' which reflected wrong values
131 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
132 measured in sample points instead of byte offset
133 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
134 'Sample::FineTune'
135 - added class attribute 'Sample::LoopSize'
136 - added method GetInstrument(uint index) to class 'File'
137 - added ReadAndLoop() method to class 'Sample' which is an extension to
138 the normal Read() method to honor the sample's looping information
139 while streaming from disk
140 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
141 'eg2_ctrl_t': replaced this huge enumeration by a structure which
142 reflects the MIDI controller number in case of an ordinary control
143 change controller (this saves a huge switch-case block in the
144 application of the library user)
145 - renamed following attributes in class 'DimensionRegion':
146 'AttenuationContol' -> 'AttenuationController',
147 'InvertAttenuationControl' -> 'InvertAttenuationController',
148 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
149 - minor fix in API documentation for method GetVelocityAttenuation() in
150 class 'DimensionRegion'
151
152 * src/RIFF.cpp, src/RIFF.h:
153 - added additional API documentation
154 - minor fix in Chunk::Read() method (only a minor efficiency issue)
155
156 * src/gigdump.cpp:
157 - added printout of samples' looping informations
158
159 Version 0.6.0 (3 Nov 2003)
160
161 * initial release
