File size: 3537 byte(s)
* src/gig.h, src/gig.cpp: fixed / improved accuracy of all three velocity
  to volume transformation functions (a.k.a. 'nonlinear','linear',
  'special'), denormals are filtered from the velocity to volume tables
* src/gigdump.cpp: added printout of velocity response curve parameters

1 schoenebeck 196 Version CVS HEAD (?)
2    
3     * packaging changes:
4     - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
5     'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
6    
7 schoenebeck 231 * src/gig.cpp, src/gig.h:
8     - fixed / improved accuracy of all three velocity to volume
9     transformation functions (a.k.a. 'nonlinear','linear','special')
10     - denormals are filtered from the velocity to volume tables
11    
12 schoenebeck 220 * src/gigextract.cpp:
13     - added support for libsndfile (if libaudiofile and libsndfile are
14     available then libsndfile is preferred)
15    
16 schoenebeck 229 * src/gigdump.cpp:
17     - added printout for dimension informations (amount, type, bits, zones)
18 schoenebeck 231 - added printout for velocity response curve parameters
19 schoenebeck 229
20 capela 168 Version 0.7.1 (2 Jul 2004)
21    
22     * packaging changes:
23 schoenebeck 192 - added libgig.spec and libgig.pc package configurations for generating
24     Redhat packages
25 capela 168 - header files included on installation.
26     - autotools-generated files removed from CVS repository.
27 schoenebeck 186 - added support for generating Debian packages
28     - version of shared library can be set in configure.in
29    
30 schoenebeck 58 Version 0.7.0 (3 May 2004)
31    
32     * general changes:
33     - various big endian specific corrections
34     (successfully tested now on PPC)
35     - minor adjustments to avoid compile errors on some systems
36     (using now pow() instead of powl() and --pedantic g++ compiler switch)
37     - libtoolized the library
38     - added man pages for the command line tools
39     (gigextract, gigdump, dlsdump, rifftree)
40    
41     * src/gig.cpp, src/gig.h:
42     - fixed bug in decompression algorithm which caused it not to detect
43     the end of a stream
44     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
45     takes the MIDI key velocity value as an argument and returns the
46     appropriate volume factor (0.0 ... 1.0) for the sample to be played
47     back, the velocity curve transformation functions used for this are
48     only an approximation so far
49     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
50     'Sample::LoopSize' which reflected wrong values
51     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
52     measured in sample points instead of byte offset
53     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
54     'Sample::FineTune'
55     - added class attribute 'Sample::LoopSize'
56     - added method GetInstrument(uint index) to class 'File'
57     - added ReadAndLoop() method to class 'Sample' which is an extension to
58     the normal Read() method to honor the sample's looping information
59     while streaming from disk
60     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
61     'eg2_ctrl_t': replaced this huge enumeration by a structure which
62     reflects the MIDI controller number in case of an ordinary control
63     change controller (this saves a huge switch-case block in the
64     application of the library user)
65     - renamed following attributes in class 'DimensionRegion':
66     'AttenuationContol' -> 'AttenuationController',
67     'InvertAttenuationControl' -> 'InvertAttenuationController',
68     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
69     - minor fix in API documentation for method GetVelocityAttenuation() in
70     class 'DimensionRegion'
71    
72     * src/RIFF.cpp, src/RIFF.h:
73     - added additional API documentation
74     - minor fix in Chunk::Read() method (only a minor efficiency issue)
75    
76     * src/gigdump.cpp:
77     - added printout of samples' looping informations
78    
79 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
80    
81     * initial release
