Sun Sep 5 00:46:28 2004 UTC (14 years, 11 months ago) by schoenebeck
Original Path: libgig/trunk/src/gigdump.cpp
File size: 14922 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
