* 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 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 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 - added some file format compatibility checks
10 - 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 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
16 - fixed crash which occured when patches did not have a sample assigned
17 to their region or dimension region (patch by Andreas Persson)
18 - 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
23 * src/gigdump.cpp:
24 - added output of UnityNote and FineTune
25
26 * src/gigextract.cpp:
27 - support for compressed mono samples and compressed 24 bit samples
28
29 Version 1.0.0 (26 Nov 2004)
30
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 - 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
39 * src/gig.cpp, src/gig.h:
40 - fixed / improved accuracy of all three velocity to volume
41 transformation functions a.k.a. 'nonlinear','linear','special'
42 (patch by Andreas Persson)
43 - denormals are filtered from the velocity to volume tables
44 - 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 - fixed panorama value in DimensionRegion (invalid conversion from
48 signed 7 bit to signed 8 bit)
49 - added class attribute 'Layers' to class 'gig::Region'
50 - symbol prototyping of gig::Region (fixes build failure with qsampler)
51
52 * src/gigextract.cpp:
53 - added support for libsndfile (if libaudiofile and libsndfile are
54 available then libsndfile is preferred)
55
56 * src/gigdump.cpp:
57 - added printout for dimension informations (amount, type, bits, zones)
58 - added printout for velocity response curve parameters
59 - added printout for crossfade definitions
60 - added printout for panorama value for each DimensionRegion
61 - replaced printout of DLS Region layer by printout of amount of
62 Gigasampler layers
63
64 Version 0.7.1 (2 Jul 2004)
65
66 * packaging changes:
67 - added libgig.spec and libgig.pc package configurations for generating
68 Redhat packages
69 - header files included on installation.
70 - autotools-generated files removed from CVS repository.
71 - added support for generating Debian packages
72 - version of shared library can be set in configure.in
73
74 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 Version 0.6.0 (3 Nov 2003)
124
125 * initial release
