[francesco]

Hi

i started several years ago to rip my cd collection

i did start with audiograbber and AudioCatalyst under w98se

quickly i changed them to cdex and eac

now honestly i don't know if my mp3 have the gapless tag

outside auduicatalyst(i use few time) i always used lame.exe

i talking about my cd collections ripped about several and several years ago

now , my problem , i don't know if they have gapless tags

i use foobar , in the properties ,there is nothing about gapless 576

when i use edit mp3 gapless playback information , some mp3 has the 576 value , other nothing

if there are not gapless , is there a free software or an editor that can trim the silence in the beginning and the end of the songs without hack the quality or add this gapless tag?

maybe that can scan my collection and find the mp3 without gapless


thanks
i would appricate it a lot
