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 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
7 * 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 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 - added some file format compatibility checks
14 - 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 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
20 - fixed crash which occured when patches did not have a sample assigned
21 to their region or dimension region (patch by Andreas Persson)
22 - 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 - external decompression buffers can now be used for streaming samples
27 to avoid race conditions in case of multiple streaming threads
28 - added pre-calculated sample attenuation parameter
29 - added v3 "random" and "round robin" dimensions
30
31 * src/gigdump.cpp:
32 - added output of UnityNote and FineTune
33 - added output of Gain and SampleStartOffset
34
35 * src/gigextract.cpp:
36 - support for compressed mono samples and compressed 24 bit samples
37
38 Version 1.0.0 (26 Nov 2004)
39
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 - 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
48 * src/gig.cpp, src/gig.h:
49 - fixed / improved accuracy of all three velocity to volume
50 transformation functions a.k.a. 'nonlinear','linear','special'
51 (patch by Andreas Persson)
52 - denormals are filtered from the velocity to volume tables
53 - 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 - fixed panorama value in DimensionRegion (invalid conversion from
57 signed 7 bit to signed 8 bit)
58 - added class attribute 'Layers' to class 'gig::Region'
59 - symbol prototyping of gig::Region (fixes build failure with qsampler)
60
61 * src/gigextract.cpp:
62 - added support for libsndfile (if libaudiofile and libsndfile are
63 available then libsndfile is preferred)
64
65 * src/gigdump.cpp:
66 - added printout for dimension informations (amount, type, bits, zones)
67 - added printout for velocity response curve parameters
68 - added printout for crossfade definitions
69 - added printout for panorama value for each DimensionRegion
70 - replaced printout of DLS Region layer by printout of amount of
71 Gigasampler layers
72
73 Version 0.7.1 (2 Jul 2004)
74
75 * packaging changes:
76 - added libgig.spec and libgig.pc package configurations for generating
77 Redhat packages
78 - header files included on installation.
79 - autotools-generated files removed from CVS repository.
80 - added support for generating Debian packages
81 - version of shared library can be set in configure.in
82
83 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 Version 0.6.0 (3 Nov 2003)
133
134 * initial release
