+/*
+** Intel/DVI ADPCM coder/decoder.
+**
+** The algorithm for this coder was taken from the IMA Compatability Project
+** proceedings, Vol 2, Number 2; May 1992.
+**
+** Version 1.2, 18-Dec-92.
+**
+** Change log:
+** - Fixed a stupid bug, where the delta was computed as
+** stepsize*code/4 in stead of stepsize*(code+0.5)/4.
+** - There was an off-by-one error causing it to pick
+** an incorrect delta once in a blue moon.
+** - The NODIVMUL define has been removed. Computations are now always done
+** using shifts, adds and subtracts. It turned out that, because the standard
+** is defined using shift/add/subtract, you needed bits of fixup code
+** (because the div/mul simulation using shift/add/sub made some rounding
+** errors that real div/mul don't make) and all together the resultant code
+** ran slower than just using the shifts all the time.
+** - Changed some of the variable names to be more meaningful.
