       -E file, --equalizer
              Enables  equalization,  taken from file.  The file needs to con-
              tain 32 lines of data, additional comment lines may be  prefixed
              with  #.  Each data line consists of two floating-point entries,
              separated by whitespace.  They specify the multipliers for  left
              and  right  channel  of  a certain frequency band, respectively.
              The first line corresponds to the lowest, the 32nd to the  high-
              est frequency band.
