File size: 6101 byte(s)
* src/gig.h, src/gig.cpp: 24-bit decompression now supports the 20 and
  18 bit formats
* src/gig.h, src/gig.cpp: added "random" and "round robin" dimensions

1 schoenebeck 317 Version CVS HEAD (?)
2    
3 schoenebeck 383 * packaging changes:
4     - fixed conditional linkage of either libsndfile or libaudiofile
5     (if none of the two exist, configure script will abort)
6    
7 schoenebeck 317 * src/gig.cpp, src/gig.h:
8     - experimental support for Gigasampler v3 format;
9     64 bit file offsets are truncated to 32 bit, 24 bit samples are
10 schoenebeck 347 truncated to 16 bit, up to 8 dimensions are read, additional
11     articulation informations are ignored at the moment
12     (patch by Andreas Persson)
13 schoenebeck 317 - added some file format compatibility checks
14 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
15     never used, because the necessary check was made before
16     initialization)
17     - fixed crossfade points order (structure for big endian and little
18     endian systems was interchanged)
19 schoenebeck 355 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
20 schoenebeck 352 - fixed crash which occured when patches did not have a sample assigned
21     to their region or dimension region (patch by Andreas Persson)
22 persson 365 - support for compressed mono samples
23     - experimental support for compressed 24 bit samples
24     - fixed decompression on big-endian CPUs
25     - fixed decompression bug that truncated the last block of samples
26 schoenebeck 384 - external decompression buffers can now be used for streaming samples
27     to avoid race conditions in case of multiple streaming threads
28 persson 406 - added pre-calculated sample attenuation parameter
29 persson 437 - added v3 "random" and "round robin" dimensions
30 schoenebeck 317
31 schoenebeck 334 * src/gigdump.cpp:
32     - added output of UnityNote and FineTune
33 persson 406 - added output of Gain and SampleStartOffset
34 schoenebeck 334
35 persson 365 * src/gigextract.cpp:
36     - support for compressed mono samples and compressed 24 bit samples
37    
38 schoenebeck 315 Version 1.0.0 (26 Nov 2004)
39 schoenebeck 196
40     * packaging changes:
41     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
42     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
43 schoenebeck 315 - fixed man pages automake install rule (which didn't work on Mandrake,
44     SuSE and Fedora)
45     - fixed generation of Doxygen API documentation (now also included in
46     RPM and Debian packages)
47 schoenebeck 196
48 schoenebeck 231 * src/gig.cpp, src/gig.h:
49     - fixed / improved accuracy of all three velocity to volume
50 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
51     (patch by Andreas Persson)
52 schoenebeck 231 - denormals are filtered from the velocity to volume tables
53 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
54     trigger dimension, no bit range check for dimensions of split type
55     'split_type_bit')
56 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
57     signed 7 bit to signed 8 bit)
58 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
59 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
60 schoenebeck 231
61 schoenebeck 220 * src/gigextract.cpp:
62     - added support for libsndfile (if libaudiofile and libsndfile are
63     available then libsndfile is preferred)
64    
65 schoenebeck 229 * src/gigdump.cpp:
66     - added printout for dimension informations (amount, type, bits, zones)
67 schoenebeck 231 - added printout for velocity response curve parameters
68 schoenebeck 235 - added printout for crossfade definitions
69 schoenebeck 269 - added printout for panorama value for each DimensionRegion
70 schoenebeck 282 - replaced printout of DLS Region layer by printout of amount of
71     Gigasampler layers
72 schoenebeck 229
73 capela 168 Version 0.7.1 (2 Jul 2004)
74    
75     * packaging changes:
76 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
77     Redhat packages
78 capela 168 - header files included on installation.
79     - autotools-generated files removed from CVS repository.
80 schoenebeck 186 - added support for generating Debian packages
81     - version of shared library can be set in configure.in
82    
83 schoenebeck 58 Version 0.7.0 (3 May 2004)
84    
85     * general changes:
86     - various big endian specific corrections
87     (successfully tested now on PPC)
88     - minor adjustments to avoid compile errors on some systems
89     (using now pow() instead of powl() and --pedantic g++ compiler switch)
90     - libtoolized the library
91     - added man pages for the command line tools
92     (gigextract, gigdump, dlsdump, rifftree)
93    
94     * src/gig.cpp, src/gig.h:
95     - fixed bug in decompression algorithm which caused it not to detect
96     the end of a stream
97     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
98     takes the MIDI key velocity value as an argument and returns the
99     appropriate volume factor (0.0 ... 1.0) for the sample to be played
100     back, the velocity curve transformation functions used for this are
101     only an approximation so far
102     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
103     'Sample::LoopSize' which reflected wrong values
104     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
105     measured in sample points instead of byte offset
106     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
107     'Sample::FineTune'
108     - added class attribute 'Sample::LoopSize'
109     - added method GetInstrument(uint index) to class 'File'
110     - added ReadAndLoop() method to class 'Sample' which is an extension to
111     the normal Read() method to honor the sample's looping information
112     while streaming from disk
113     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
114     'eg2_ctrl_t': replaced this huge enumeration by a structure which
115     reflects the MIDI controller number in case of an ordinary control
116     change controller (this saves a huge switch-case block in the
117     application of the library user)
118     - renamed following attributes in class 'DimensionRegion':
119     'AttenuationContol' -> 'AttenuationController',
120     'InvertAttenuationControl' -> 'InvertAttenuationController',
121     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
122     - minor fix in API documentation for method GetVelocityAttenuation() in
123     class 'DimensionRegion'
124    
125     * src/RIFF.cpp, src/RIFF.h:
126     - added additional API documentation
127     - minor fix in Chunk::Read() method (only a minor efficiency issue)
128    
129     * src/gigdump.cpp:
130     - added printout of samples' looping informations
131    
132 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
133    
134     * initial release
