Make mpg123 write the sample data to standard output, pipe through a
filter, pipe into pcmplay:

    mpg123 -s foo.mp3 | ... | pcmplay -b1024 -

pcmplay is part of ports/audio/tosha.  If you examine the audio
section of the ports collection, you can probably find filters for
various functions.  sox is a good candidate.  Or you can write your
own. ;-)
