409 schoenebeck 58 Version 0.7.0 (3 May 2004)
410    
411     * general changes:
412     - various big endian specific corrections
413     (successfully tested now on PPC)
414     - minor adjustments to avoid compile errors on some systems
415     (using now pow() instead of powl() and --pedantic g++ compiler switch)
416     - libtoolized the library
417     - added man pages for the command line tools
418     (gigextract, gigdump, dlsdump, rifftree)
419    
420     * src/gig.cpp, src/gig.h:
421     - fixed bug in decompression algorithm which caused it not to detect
422     the end of a stream
423     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
424     takes the MIDI key velocity value as an argument and returns the
425     appropriate volume factor (0.0 ... 1.0) for the sample to be played
426     back, the velocity curve transformation functions used for this are
427     only an approximation so far
428     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
429     'Sample::LoopSize' which reflected wrong values
430     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
431     measured in sample points instead of byte offset
432     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
433     'Sample::FineTune'
434     - added class attribute 'Sample::LoopSize'
435     - added method GetInstrument(uint index) to class 'File'
436     - added ReadAndLoop() method to class 'Sample' which is an extension to
437     the normal Read() method to honor the sample's looping information
438     while streaming from disk
439     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
440     'eg2_ctrl_t': replaced this huge enumeration by a structure which
441     reflects the MIDI controller number in case of an ordinary control
442     change controller (this saves a huge switch-case block in the
443     application of the library user)
444     - renamed following attributes in class 'DimensionRegion':
445     'AttenuationContol' -> 'AttenuationController',
446     'InvertAttenuationControl' -> 'InvertAttenuationController',
447     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
448     - minor fix in API documentation for method GetVelocityAttenuation() in
449     class 'DimensionRegion'
450    
451     * src/RIFF.cpp, src/RIFF.h:
452     - added additional API documentation
453     - minor fix in Chunk::Read() method (only a minor efficiency issue)
454    
455     * src/gigdump.cpp:
456     - added printout of samples' looping informations
457    
458 schoenebeck 11 Version 0.6.0 (3 Nov 2003)
459    
460     * initial release
