Thu Feb 17 02:22:26 2005 UTC (19 years, 5 months ago) by schoenebeck
File size: 5943 byte(s)
* gig::Sample: external decompression buffers can now be used for streaming
  with Read() and ReadAndLoop() to avoid race conditions in case of
  multiple streaming threads
* fixed some memory leaks caused by non virtual base constructors

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
29 * src/gigdump.cpp:
30 - added output of UnityNote and FineTune
31
32 * src/gigextract.cpp:
33 - support for compressed mono samples and compressed 24 bit samples
34
35 Version 1.0.0 (26 Nov 2004)
36
37 * packaging changes:
38 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
39 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
40 - fixed man pages automake install rule (which didn't work on Mandrake,
41 SuSE and Fedora)
42 - fixed generation of Doxygen API documentation (now also included in
43 RPM and Debian packages)
44
45 * src/gig.cpp, src/gig.h:
46 - fixed / improved accuracy of all three velocity to volume
47 transformation functions a.k.a. 'nonlinear','linear','special'
48 (patch by Andreas Persson)
49 - denormals are filtered from the velocity to volume tables
50 - bugfix for dimension region switching (wrong handling of the release
51 trigger dimension, no bit range check for dimensions of split type
52 'split_type_bit')
53 - fixed panorama value in DimensionRegion (invalid conversion from
54 signed 7 bit to signed 8 bit)
55 - added class attribute 'Layers' to class 'gig::Region'
56 - symbol prototyping of gig::Region (fixes build failure with qsampler)
57
58 * src/gigextract.cpp:
59 - added support for libsndfile (if libaudiofile and libsndfile are
60 available then libsndfile is preferred)
61
62 * src/gigdump.cpp:
63 - added printout for dimension informations (amount, type, bits, zones)
64 - added printout for velocity response curve parameters
65 - added printout for crossfade definitions
66 - added printout for panorama value for each DimensionRegion
67 - replaced printout of DLS Region layer by printout of amount of
68 Gigasampler layers
69
70 Version 0.7.1 (2 Jul 2004)
71
72 * packaging changes:
73 - added libgig.spec and libgig.pc package configurations for generating
74 Redhat packages
75 - header files included on installation.
76 - autotools-generated files removed from CVS repository.
77 - added support for generating Debian packages
78 - version of shared library can be set in configure.in
79
80 Version 0.7.0 (3 May 2004)
81
82 * general changes:
83 - various big endian specific corrections
84 (successfully tested now on PPC)
85 - minor adjustments to avoid compile errors on some systems
86 (using now pow() instead of powl() and --pedantic g++ compiler switch)
87 - libtoolized the library
88 - added man pages for the command line tools
89 (gigextract, gigdump, dlsdump, rifftree)
90
91 * src/gig.cpp, src/gig.h:
92 - fixed bug in decompression algorithm which caused it not to detect
93 the end of a stream
94 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
95 takes the MIDI key velocity value as an argument and returns the
96 appropriate volume factor (0.0 ... 1.0) for the sample to be played
97 back, the velocity curve transformation functions used for this are
98 only an approximation so far
99 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
100 'Sample::LoopSize' which reflected wrong values
101 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
102 measured in sample points instead of byte offset
103 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
104 'Sample::FineTune'
105 - added class attribute 'Sample::LoopSize'
106 - added method GetInstrument(uint index) to class 'File'
107 - added ReadAndLoop() method to class 'Sample' which is an extension to
108 the normal Read() method to honor the sample's looping information
109 while streaming from disk
110 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
111 'eg2_ctrl_t': replaced this huge enumeration by a structure which
112 reflects the MIDI controller number in case of an ordinary control
113 change controller (this saves a huge switch-case block in the
114 application of the library user)
115 - renamed following attributes in class 'DimensionRegion':
116 'AttenuationContol' -> 'AttenuationController',
117 'InvertAttenuationControl' -> 'InvertAttenuationController',
118 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
119 - minor fix in API documentation for method GetVelocityAttenuation() in
120 class 'DimensionRegion'
121
122 * src/RIFF.cpp, src/RIFF.h:
123 - added additional API documentation
124 - minor fix in Chunk::Read() method (only a minor efficiency issue)
125
126 * src/gigdump.cpp:
127 - added printout of samples' looping informations
128
129 Version 0.6.0 (3 Nov 2003)
130
131 * initial release
