am usually wrong but well..

mpg123 made at mac.mp3
shows the info of the file
and it says it is stereo

it is also the same with that of
the same file played by
the windows version of mpg123
this win version plays it ok

oh
but mpg123 also shows
that there is a junk at the biginning of the file

made at mac.wav
is also ok at windows
but half the speed at slackware

btw
workbone plays the cd ok

mmm
