-* linear2ulaw() - Convert a linear PCM value to u-law

-* In order to simplify the encoding process, the original linear magnitude
-* is biased by adding 33 which shifts the encoding range from (0 - 8158) to
-* (33 - 8191). The result can be seen in the following encoding table:

-*	01wxyzabcdefg			110wxyz
-*	1wxyzabcdefgh			111wxyz
-*
-* Each biased linear code has a leading 1 which identifies the segment
-* number. The value of the segment number is equal to 7 minus the number
-* of leading 0's. The quantization interval is directly available as the
-* four bits wxyz.  * The trailing bits (a - h) are ignored.
