It's the difference in time between the first beat of the song and the time the arrows start scrolling. Therefore, a gap of 28 would make the arrows start scrolling 0.028 seconds, or 2.8 ms, after the music starts. If it's a negative gap, like -157, then that would mean the arrows start scrolling 0.157 seconds, or 15.7 ms, before the song starts playing.
Sometimes at the start of the song, there's a delay before the music starts. You use GAP to get rid of this delay. It also makes the arrows more onsync.
I watched clouds awobbly from the floor o' that kayak. Souls cross ages like clouds cross skies, an' tho' a cloud's shape nor hue nor size don't stay the same, it's still a cloud an' so is a soul. Who can say where the cloud's blowed from or who the soul'll be 'morrow? Only Sonmi the east an' the west an' the compass an' the atlas, yay, only the atlas o' clouds.
