you're just resampling and reformatting?

sndfile-resample and sndfile-convert can both be given "-" as the name
of their output or input. they are much simpler programs that mplayer
and will also likely do a better job.

--p

af resample=44100:0:1,channels=2,format=s16le
is not so imoprtant, because most  files already are 44k stereo S16LE
If some sound files are not 44k stereo S16LE, they are just forced -to-be- 44k stereo S16LE .

Impotrant is gotta decoded RAW data (and only RAW data) to STDOUT,
and not any messages mixed with RAW data !
NEVER !
mplayer  - -ao pcm:nowaveheader:file=/dev/stdout -quiet -really-quiet  'saund_file.ext'  |  nextprog -options ...
