I want to record 16-bit wav files, but the files generated are 32-bit ones.
Put the "-b 16" option immediately before the output file argument. You
can also drop all the format options preceding the -p since the pipe
format already includes all information.
$ rec -c 2 -r 48000 -b 16 -p trim 0 20 | sox -p test.wav trim 0 10 : newfile : restart
rec WARN formats: sox can't encode to 16-bit

Done.

Is the position of "-b 16" option okay?
That said, why don't you do the splitting directly with the rec command?
This should work:
$ rec -c 2 -b 16 -r 48000 test.wav trim 0 10 : newfile : restart
I understand it, but I have to save test.wav first.
I just want to split into wav files while I record from the line input.
