When you use -s option, mp3splt attempts to detect silence points in all the file (or just in some parts, see -a and -c below for this). To detect silence we need to decode files, so this option can be really slow if used with big files. It accepts some parameters with -p option (see below for a detailed description): threshold level (th) which is the sound level to be considered silence, number of tracks (nt) which is the desired number of tracks, cutpoint offset (off) which is the offset of cutpoint in silence, minimum_length (min) which is the minimum silence length in seconds, remove silence (rm) which allows you to remove the silence between split tracks. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN AS43859
