When I set the LOGFILE field with TAG utility from the following file:
CODE

Used output format : Internal WAV Routines
                    44.100 Hz; 16 Bit; Stereo

fb2k displays 3 LOGFILE tags splitted exactly by semicolon chars, i.e., fb2k displays:

CODE
LOGFILE=(...)
LOGFILE=16 Bit
LOGFILE=Stereo
