Comment (by bernhard):

 Thank you. Ok, I changed it to:

 ffmpeg -i exil1211212315_02.wav -af atrim=0:60 -acodec pcm_s24le
 outffmpeg2.wav

 I wonder whether it would make sense to use the same encoding as the
 source file by default. That's how sox handles the situation (from the
 help output of sox):
   FORMAT OPTIONS (fopts):
   Input file format options need only be supplied for files that are
 headerless.
   Output files will have the '''same format as the input''' file where
 possible and not
   overriden by any of various means including providing output format
 options.
