Sat Sep 24 14:00:46 2016 UTC (7 years, 6 months ago) by schoenebeck
File size: 28383 byte(s)
* src/gig.cpp, src/gig.h: Fixed samples' CRC checksums were misordered
  when a Sample was deleted.
* src/gig.cpp, src/gig.h: Added new method
  Sample::GetWaveDataCRC32Checksum().
* src/tools/gigdump.cpp: print samples' CRC32 checksums.
* Bumped version (4.0.0.svn9).

1 Version SVN trunk
2 * general changes:
3 - removed 2 GB limitation when loading a gig or DLS file
4 - using now native integer size where appropriate
5
6 * src/gig.cpp, src/gig.h:
7 - fixed bug in Script::SetGroup: the script chunk wasn't moved
8 - fixed compilation error with clang 3.4
9 - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
10 as one single monolithic gig file. In case .gig file is >= 2GB expect a
11 large monolithic file, otherwise if .gig file is < 2 GB check for
12 "extension" files (.gx01, .gx02, ...) instead.
13 - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
14 if there were dimensions after the velocity dimension: it only created
15 valid velocity tables for cases of dimensions lower than the velocity
16 dimension.
17 - added new method Sample::VerifyWaveData() which allows to check whether
18 a sample had been damaged for some reason
19 - Fix: samples' CRC checksums were damaged on file structure changes.
20 - Fix: samples' CRC checksums were misordered when a Sample was deleted.
21 - Added new method Sample::GetWaveDataCRC32Checksum().
22
23 * src/DLS.cpp, src/DLS.h:
24 - Sample: wave pool offsets are now 64 bits (to allow support for files
25 larger than 4 GB).
26
27 * src/RIFF.cpp, src/RIFF.h:
28 - added support for RIFF files larger than 4 GB, by default the required
29 internal RIFF file offset size is automatically detected (that is RIFF
30 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
31 automatically use 64 bit offsets), a particular offset size can be forced
32 with a new option added to the RIFF File constructor though
33 - when saving a modified, grown RIFF file, the temporary file size during
34 Save() operation will no longer be larger than the final grown file size
35
36 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
37 - improved output of non-ascii characters in usage messages
38 - fixed printf format strings
39
40 * src/tools/korg2gig.cpp:
41 - fixed c++11 narrowing warnings
42 - fixed fine tuning which was not translated at all
43
44 * src/tools/gigdump.cpp:
45 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
46 dimension regions
47 - additionally print RIFF chunk file offset and RIFF chunk size of sample
48 data
49 - added and implemented new parameter "--verify" which allows to check
50 the raw wave form data integrity of all samples
51 - added and implemented new parameter "--rebuild-checksums" which allows
52 to recalculate the CRC32 checksum of all samples' raw wave data and
53 rebuilding the gig file's global checksum table (i.e. in case the
54 file's checksum table was damaged)
55 - print samples' CRC32 checksums
56
57 * src/tools/gigextract.cpp:
58 - Fix: if sample name contains a path separator (slash or backslash) then
59 replace them by a minus sign to avoid file system issues.
60
61 * packaging changes:
62 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
63 auto detect whether it (sh/c)ould output its messages in color.
64
65 Version 4.0.0 (14 Jul 2015)
66 * general changes:
67 - minor Makefile fix for parallel make
68 - Mac OS X: link with CoreFoundation (for the UUID function)

88
89 * SoundFont file format:
90 - initial implementation
91 - changed region lookup API to avoid malloc in RT threads
92 - fixed GetEG1Sustain which didn't return correct value
93 - bugfix: GetPan always returned -1, 0 or 1
94

96 - initial support for sample based instruments in KORG's file format
97 (.KMP and .KSF files)
98
99 * AKAI file format:
100 - Added Linux/POSIX ported version of libakai. Note that libakai is released
101 under LGPL terms while libgig is released under GPL terms. To handle this
102 license difference appropriately the AKAI support part is built as
103 separate DLL (.so file).
104 - Fixed Mac OSX support so that the Akai lib files and tools compile without
105 any exotic third party libraries.
106 - Fixed various compilation errors for Windows.
107 - POSIX fix: open() requires third (mode) argument if used with O_CREAT

135 - added new method Region::GetDimensionRegionIndexByValue()
136 - added new method Script::GetGroup()
137 - added new method Region::SetDimensionType()
138 - Added support for custom progress notification while saving to gig file.

173 - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
174 allows to move a subchunk within the current List, whereas the new 2nd
175 one allows to move the subchunk from the current list to another list
176 - POSIX: only assume -1 result value as error on open() calls
177 - POSIX: show operating system's error reason if opening a file failed

278 - write support: DLSID is now generated on the file and the
279 instruments
280 - write support: improved the default values for dimension region
281 parameters

284 when dimensions were added or deleted, v3 wave pool offsets were
285 not saved correctly
286 - write support: 24 bit samples can now be written

330 with the group
331 - added Instrument::MoveRegion method
332 - fixed constructor for Region, which did not initialize correctly
333 when used from Instrument::AddRegion
334 - when saving, override the gig::Regions sample reference simply by
335 the region's first dimension region's sample (avoids an exception
336 when trying to save a new instrument)

512 libgig version
513
514 * src/gigdump.cpp:
515 - added output of UnityNote, FineTune, Gain, SampleStartOffset an
516 LoopPlayCount
517 - added command line switch -v to show gigdump's revision and the used
518 libgig version
519
520 * src/gigextract.cpp:
521 - support for compressed mono samples and compressed 24 bit samples
522 - added command line switch -v to show gigextract's revision and the
523 used libgig version
524
525 Version 1.0.0 (26 Nov 2004)
526
527 * packaging changes:
528 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
529 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
530 - fixed man pages automake install rule (which didn't work on Mandrake,
531 SuSE and Fedora)
532 - fixed generation of Doxygen API documentation (now also included in
533 RPM and Debian packages)
534
535 * src/gig.cpp, src/gig.h:
536 - fixed / improved accuracy of all three velocity to volume
537 transformation functions a.k.a. 'nonlinear','linear','special'
538 (patch by Andreas Persson)
539 - denormals are filtered from the velocity to volume tables
540 - bugfix for dimension region switching (wrong handling of the release
541 trigger dimension, no bit range check for dimensions of split type
542 'split_type_bit')
543 - fixed panorama value in DimensionRegion (invalid conversion from
544 signed 7 bit to signed 8 bit)
545 - added class attribute 'Layers' to class 'gig::Region'
546 - symbol prototyping of gig::Region (fixes build failure with qsampler)
547
548 * src/gigextract.cpp:
549 - added support for libsndfile (if libaudiofile and libsndfile are
550 available then libsndfile is preferred)
551
552 * src/gigdump.cpp:
553 - added printout for dimension informations (amount, type, bits, zones)
554 - added printout for velocity response curve parameters
555 - added printout for crossfade definitions
556 - added printout for panorama value for each DimensionRegion
557 - replaced printout of DLS Region layer by printout of amount of
558 Gigasampler layers
559
560 Version 0.7.1 (2 Jul 2004)
561
562 * packaging changes:
563 - added libgig.spec and libgig.pc package configurations for generating
564 Redhat packages
565 - header files included on installation.
566 - autotools-generated files removed from CVS repository.
567 - added support for generating Debian packages
568 - version of shared library can be set in configure.in
569
570 Version 0.7.0 (3 May 2004)
571
572 * general changes:
573 - various big endian specific corrections
574 (successfully tested now on PPC)
575 - minor adjustments to avoid compile errors on some systems
576 (using now pow() instead of powl() and --pedantic g++ compiler switch)
577 - libtoolized the library
578 - added man pages for the command line tools
579 (gigextract, gigdump, dlsdump, rifftree)
580
581 * src/gig.cpp, src/gig.h:
582 - fixed bug in decompression algorithm which caused it not to detect
583 the end of a stream
584 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
585 takes the MIDI key velocity value as an argument and returns the
586 appropriate volume factor (0.0 ... 1.0) for the sample to be played
587 back, the velocity curve transformation functions used for this are
588 only an approximation so far
589 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
590 'Sample::LoopSize' which reflected wrong values
591 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
592 measured in sample points instead of byte offset
593 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
594 'Sample::FineTune'
595 - added class attribute 'Sample::LoopSize'
596 - added method GetInstrument(uint index) to class 'File'
597 - added ReadAndLoop() method to class 'Sample' which is an extension to
598 the normal Read() method to honor the sample's looping information
599 while streaming from disk
600 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
601 'eg2_ctrl_t': replaced this huge enumeration by a structure which
602 reflects the MIDI controller number in case of an ordinary control
603 change controller (this saves a huge switch-case block in the
604 application of the library user)
605 - renamed following attributes in class 'DimensionRegion':
606 'AttenuationContol' -> 'AttenuationController',
607 'InvertAttenuationControl' -> 'InvertAttenuationController',
608 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
609 - minor fix in API documentation for method GetVelocityAttenuation() in
610 class 'DimensionRegion'
611
612 * src/RIFF.cpp, src/RIFF.h:
613 - added additional API documentation
614 - minor fix in Chunk::Read() method (only a minor efficiency issue)
615
616 * src/gigdump.cpp:
617 - added printout of samples' looping informations
618
619 Version 0.6.0 (3 Nov 2003)
620
621 * initial release
