18                                       the Gigasampler file format.                                       the Gigasampler/GigaStudio file format.
19    
20      Despite its name, libgig also provides (since version 4.0.0) support for
21      other sampler file formats as well:
22    
23      - SoundFont classes (SF.h, SF.cpp):  They provide support for the very popular
24                                           SoundFont v1 and v2 format (.sf2).
25    
26      - KORG classes (Korg.h, Korg.cpp):   Provides support for sample based sounds
27                                           used on many KORG synthesizer keyboards.
28    
29      - Akai classes (Akai.h):             Currently S1000, S01, S2000 and S3000
30                                           series are supported.
31    
32      Additionally libgig contains the following separate API:
33    
34      - Serialization classes (Serialization.h, Serialization.cpp):
35                                           Framework to serialize and deserialize
36                                           the runtime state of native C++ objects
37                                           (for saving and restoring their states
38                                           as abstract data).
39    
40      Beside the actual library there are following example applications:
41    
42        gigdump:     Demo app that prints out the content of a .gig file.
43        gigextract:  Extracts samples from a .gig file.
44        gigmerge:    Merges several .gig files to one .gig file.
45        gig2mono:    Converts .gig files from stereo to mono.
46        gig2stereo:  Converts .gig files to true interleaved stereo sounds.
47        wav2gig:     Creates a new .gig file from a set of .wav files.
48        dlsdump:     Demo app that prints out the content of a DLS file.
49        korgdump:    Prints out the content of the various KORG file types.
50        korg2gig:    Convert KORG sound file to Gigasampler/GigaStudio format.
51        sf2dump:     Prints out the content of a .sf2 file.
52        sf2extract:  Extracts audio samples from a .sf2 file.
53        rifftree:    Tool that prints out the RIFF tree of an arbitrary RIFF
54                     file.
55        akaidump:    Dump an AKAI media i.e. from a CDROM drive as disk image file
56                     to your hard disk drive.
57        akaiextract: Extracts samples from an Akai disk image, either from a media
58                     (i.e. CDROM or Zip drive) for from a AKAI disk image file.
59    
60      Since version 3.0.0 libgig also provides write support, that is for
61      creating modifying .gig, DLS and RIFF files.
62    
63  Requirements  Requirements
64  ============  ============
   I simply used automake & co this time so you will need to have automake,  
   autoconf and libtool installed. I used the following versions:  
65    
66      automake  1.6.3    All systems
67      autoconf  2.57    -----------
68    
69    If you want to compile the 'gigextract' application that comes with these    Since libgig 4.3.0 you need at least a C++11 compliant compiler.
   sources then you will additionally need to have libaudiofile (>= 0.2.3)  
   or libsndfile (>= 1.0.2) installed. Note: for Windows systems only  
   libsndfile is available.  
70    
71  Non-POSIX systems    POSIX systems (e.g. Linux, macOS):
72  =================    ---------------------------------
   If you don't have a POSIX system, you have to set 'POSIX' to '0' in RIFF.h.  
   Instead of using POSIX calls then standard C calls will be used for file  
   access. This applies e.g. to Windows systems.  
73    
74  Compiling    You need at least to have libtool installed to be able to build the
75  =========    library with "./configure && make".
76    
77      Additionally you need to have either libaudiofile (>= 0.2.3) or
78      libsndfile (>= 1.0.2) installed which is mandatory to be able to compile
79      the 'gigextract' example application. But of course 'gigextract' is still
80      just an example application, so it would make sense to compile it only if
81      one of those libraries are available. That would remove that hard
82      dependency to those two libs. But that's not a priority for me now.
83      Note: for Windows systems only libsndfile is available.
84    
85      If you want to regenerate all autotools build files (that is configure,
86      Makefile.in, etc.) then you need to have automake (>= 1.5) and autoconf
87      installed.
88    
89      Windows:
90      --------
91    
92      The precompiled versions of libgig (and its tools) should be compatible
93      with any Windows operating system of at least Win95 or younger. Notice
94      that all example / demo applications coming with libgig are pure console
95      applications, thus you won't see a GUI showing up! :)
96    
97      If you want to compile libgig and its tools by yourself, please also
98      notice the requirements under "Compiling for Windows".
99    
100      Other Operating Systems:
101      ------------------------
102    
103      libgig was written to compile for any operating system, using standard C
104      library functions. However there are some OS dependent requirements:
105    
106      * Since libgig 3.0.0 an OS dependent implementation for a tiny method called
107        RIFF::File::ResizeFile() is required. So you would either have to add
108        native OS API calls for that particular method, that is dependant to your
109        OS, or you have to add a portable implementation. No matter which way you
110        choose, please let us know! :)
111    
112      * Since libgig 4.3.0 presence of some UUID generating function is required to
113        be provided by the underlying system. This was an optional feature in
114        previous versions of libgig for many years, its absence only meant that you
115        were unable to load gig files created/modified by libgig to be accepted by
116        Tascam's original GigaStudio studio software, did not mean any restriction
117        for being used with LinuxSampler though. This has changed in the meantime,
118        so this is now a hard build requirement, as you would potentially encounter
119        misbehaviours now even if you stay entirely in the Linux eco system if UUIDs
120        were missing in gig files.
121

170    
171  Tools  Compiling for Windows using CMake
172  =====  =================================
173    The easiest way is to compile is to use vcpkg (https://github.com/Microsoft/vcpkg)
174    to install libsndfile (required) and cppunit (optional). In the vcpkg install dir
175    type:
176    .\vcpkg.exe install libsndfile cppunit [--triplet x64-windows]
177    
178    This should install the libraries in vcpkg, add the triplet option if you wish to
179    get the 64bit libraries.
180    
181    In an empty directory type:
182    cmake <libgig source dir> -DCMAKE_TOOLCHAIN_FILE=<vcpkg dir>\scripts\buildsystems\vcpkg.cmake
183    [-G"Visual Studio 15 2017 Win64"]
184    
185    Use the -G option to select the visual studio version and whether to compile for
186    64bits.
187    
188    This will create libgig.sln file which you can open in visual studio or you can use
189    the following command line to compile:
190    
191    cmake --build . --config <Release|Debug|MinRelSize|RelWithDebInfo>
192    
193    Compiling for Windows using Dev-C++
194    ===================================
195    
196      libgig and its tools can also be compiled on Windows using Bloodshed Dev-C++,
197      which is a free (GPL) C++ integrated development environment for Windows.
198      It is also possible to use MSYS from MinGW, which allows you to use
199      './configure && make' like the linux builds.
200    
201      You can download Dev-C++ here:
202    
203        http://www.bloodshed.net/devcpp.html
204    
205      Make sure you install a version with Mingw integrated.
206    
207      a) Compiling libgig.dll
208    
209      Simply open the project file "win32/libgig.dev" either directly in Dev-C++
210      or by double clicking on the project file in the Windows explorer, then
211      click on "Compile" in the Dev-C++ menu and that's it! After compilation
212      finished, you can find the files "libgig.dll", "libgig.a" and
213      "liblibgig.def" in the "win32" directory.
214    
215   Beside the actual library there are four applications:    b) Compiling the example tools "rifftree", "dlsdump" and "gigdump"
216    
217       gigdump:     Demo app that prints out the content of a .gig file.    You need to have libgig.dll compiled as described in a). Then you can
218       gigextract:  Extracts samples from a .gig file.    compile the respective tool by simply opening the respective project
219       dlsdump:     Demo app that prints out the content of a DLS file.    (.dev) file and clicking on "Compile" from the Dev-C++ menu. After
220       rifftree:    Tool that prints out the RIFF tree of an arbitrary RIFF    compilation you can find the respective .exe file in the "win32"
221                    file.    directory.
222    
223      c) Compiling the example tool "gigextract"
224    
225      You need to have libgig.dll compiled as described in a). Also you need
226      libsndfile (as DLL) which is used to create the .wav files. You can
227      download libsndfile already precompiled as DLL here:
228    
229        http://www.mega-nerd.com/libsndfile/
230    
231      Extract the .zip file i.e. to "C:\". The libsndfile .dll file should then
232      be i.e. under "C:\libsndfile-1_0_17". Beside the .dll file, make sure
233      libsndfile's .lib file exists in that directory as well. If the .lib file
234      does not exist yet, you have to create it with:
235    
236        dlltool --input-def libsndfile-1.def --output-lib libsndfile-1.lib
237    
238      Then you have to ensure the settings of gigextract's Dev-C++ project file
239      are pointing to the correct location of your local copy of libsndfile. For
240      that click in the Dev-C++ menu on "Project" -> "Project Options". Then
241      click on the tab "Parameter" and make sure the path to "libsndfile-1.lib"
242      in the "Linker" list view is correct. Then click on the tab "Directories"
243      and then on the tab "Include Directories" and make sure the path to
244      libsndfile points to the correct location there as well.
245    
246      After that you should finally be able to compile "gigextract" by clicking
247      on "Compile" in the Dev-C++ menu. After compilation succeeded, you can
248      find the "gigextract.exe" file in the "win32" directory.
249    
250    Test Cases
251    ==========
252      The libgig sources come with a tiny console application which allows to
253      automatically test libgig's functions on your system. This test
254      application is not compiled by default, you have to compile it explicitly
255      with the following commands on the console (cppunit has to be installed):
256    
257        cd src/testcases
258        make libgigtests
259    
260      and then run the test application from the same directory with:
261    
262        ./libgigtests
263    
264    License
265    =======
266      libgig and its tools are released under the GNU General Public License (GPL).
267    
268      libakai and its tools are released under the GNU Lesser General Public (LGPL).
269      Due to its different license model the Akai support part is built as separate
270      DLL (.so) file.

296  =======  =======
297    This library is based on the reverse engineering work of Paul Kellett and    The initial library (Gigasampler part) was based on the reverse engineering
298    Ruben van Royen. Thanks for your great work!    effort of Paul Kellett and Ruben van Royen. We owe current support for the
299      Gigasampler v3/v4 format to Andreas Persson. Please also have a look at the
300      ChangeLog for all those who contributed.
301    
302      Akai support files are a ported version of Sébastien Métrot's libakai. The
303      original libakai only supported Mac and Windows. This forked version of
304      libakai now also supports Linux and other POSIX compliant operating systems
305      as well and does not have a dependency to libngl as the original libakai had.
306    
307      The SoundFont 2 file format C++ classes were written by Grigor Iliev.
