* src/gig.cpp, src/gig.h, src/gigextract.cpp: Support for compressed
  mono samples. Experimental support for compressed 24 bit
  samples. Fixes for decompression on big-endian CPUs. Fix for bug
  that truncated end of compressed samples.

1 schoenebeck 317 Version CVS HEAD (?)
2    
3     * src/gig.cpp, src/gig.h:
4     - experimental support for Gigasampler v3 format;
5     64 bit file offsets are truncated to 32 bit, 24 bit samples are
6 schoenebeck 347 truncated to 16 bit, up to 8 dimensions are read, additional
7     articulation informations are ignored at the moment
8     (patch by Andreas Persson)
9 schoenebeck 317 - added some file format compatibility checks
10 schoenebeck 345 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
11     never used, because the necessary check was made before
12     initialization)
13     - fixed crossfade points order (structure for big endian and little
14     endian systems was interchanged)
15 schoenebeck 355 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
16 schoenebeck 352 - fixed crash which occured when patches did not have a sample assigned
17     to their region or dimension region (patch by Andreas Persson)
18 persson 365 - support for compressed mono samples
19     - experimental support for compressed 24 bit samples
20     - fixed decompression on big-endian CPUs
21     - fixed decompression bug that truncated the last block of samples
22 schoenebeck 317
23 schoenebeck 334 * src/gigdump.cpp:
24     - added output of UnityNote and FineTune
25    
26 persson 365 * src/gigextract.cpp:
27     - support for compressed mono samples and compressed 24 bit samples
28    
29 schoenebeck 315 Version 1.0.0 (26 Nov 2004)
30 schoenebeck 196
31     * packaging changes:
32     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
33     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
34 schoenebeck 315 - fixed man pages automake install rule (which didn't work on Mandrake,
35     SuSE and Fedora)
36     - fixed generation of Doxygen API documentation (now also included in
37     RPM and Debian packages)
38 schoenebeck 196
39 schoenebeck 231 * src/gig.cpp, src/gig.h:
40     - fixed / improved accuracy of all three velocity to volume
41 schoenebeck 315 transformation functions a.k.a. 'nonlinear','linear','special'
42     (patch by Andreas Persson)
43 schoenebeck 231 - denormals are filtered from the velocity to volume tables
44 schoenebeck 241 - bugfix for dimension region switching (wrong handling of the release
45     trigger dimension, no bit range check for dimensions of split type
46     'split_type_bit')
47 schoenebeck 269 - fixed panorama value in DimensionRegion (invalid conversion from
48     signed 7 bit to signed 8 bit)
49 schoenebeck 282 - added class attribute 'Layers' to class 'gig::Region'
50 schoenebeck 315 - symbol prototyping of gig::Region (fixes build failure with qsampler)
51 schoenebeck 231
52 schoenebeck 220 * src/gigextract.cpp:
53     - added support for libsndfile (if libaudiofile and libsndfile are
54     available then libsndfile is preferred)
55    
56 schoenebeck 229 * src/gigdump.cpp:
57     - added printout for dimension informations (amount, type, bits, zones)
58 schoenebeck 231 - added printout for velocity response curve parameters
59 schoenebeck 235 - added printout for crossfade definitions
60 schoenebeck 269 - added printout for panorama value for each DimensionRegion
61 schoenebeck 282 - replaced printout of DLS Region layer by printout of amount of
62     Gigasampler layers
63 schoenebeck 229
64 capela 168 Version 0.7.1 (2 Jul 2004)
65    
66     * packaging changes:
67 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
68     Redhat packages
69 capela 168 - header files included on installation.
70     - autotools-generated files removed from CVS repository.
71 schoenebeck 186 - added support for generating Debian packages
72     - version of shared library can be set in configure.in
73    
74 schoenebeck 58 Version 0.7.0 (3 May 2004)
75    
76     * general changes:
77     - various big endian specific corrections
78     (successfully tested now on PPC)
79     - minor adjustments to avoid compile errors on some systems
80     (using now pow() instead of powl() and --pedantic g++ compiler switch)
81     - libtoolized the library
82     - added man pages for the command line tools
83     (gigextract, gigdump, dlsdump, rifftree)
84    
85     * src/gig.cpp, src/gig.h:
86     - fixed bug in decompression algorithm which caused it not to detect
87     the end of a stream
88     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
89     takes the MIDI key velocity value as an argument and returns the
90     appropriate volume factor (0.0 ... 1.0) for the sample to be played
91     back, the velocity curve transformation functions used for this are
92     only an approximation so far
93     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
94     'Sample::LoopSize' which reflected wrong values
95     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
96     measured in sample points instead of byte offset
97     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
98     'Sample::FineTune'
99     - added class attribute 'Sample::LoopSize'
100     - added method GetInstrument(uint index) to class 'File'
101     - added ReadAndLoop() method to class 'Sample' which is an extension to
102     the normal Read() method to honor the sample's looping information
103     while streaming from disk
104     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
105     'eg2_ctrl_t': replaced this huge enumeration by a structure which
106     reflects the MIDI controller number in case of an ordinary control
107     change controller (this saves a huge switch-case block in the
108     application of the library user)
109     - renamed following attributes in class 'DimensionRegion':
110     'AttenuationContol' -> 'AttenuationController',
111     'InvertAttenuationControl' -> 'InvertAttenuationController',
112     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
113     - minor fix in API documentation for method GetVelocityAttenuation() in
114     class 'DimensionRegion'
115    
116     * src/RIFF.cpp, src/RIFF.h:
117     - added additional API documentation
118     - minor fix in Chunk::Read() method (only a minor efficiency issue)
119    
120     * src/gigdump.cpp:
121     - added printout of samples' looping informations
122    
123 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
124    
125     * initial release
