 The default encoder is set to some fixed value (16-bit Signed Integer
 PCM). So, in most cases I have to specify the encoder explicitly:

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

 However, it would be more convenient if the default encoding would be the
 same as the input file. 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.
