I think you can simplify that awk code by telling it to use all whitespace as record separators. One statement instead of four. Then you just tell it to process the "odd" lines -- 1, 3, 5, ...

You can get rid of the BEGIN block by feeding variables into awk on the commandline. This also lets you script the value of the outputfile.

I started adding pipes and stuff then saw the BINMODE, and realized that's probably why you were forced to use temp files. Oh well.

Code:
awk --characters-as-bytes 'NR%2 { printf("%c", ($1+32768)/256)) > OUT }' RS="[ \r\n\t]+" BINMODE=3 OUT="/tmp/leftbinary" /tmp/signed16bit.txt
