I don't know if it is the right place to propose some table feature. Am i wondering, if it is possible to attribute to each ship their respective FlyBy sound. I know a X wings have their own flyby sound, and tie fighters have also their own flyby sound.
But, unfortunately, the sound.tbl have some limitation because each race have their flyby sound. So, my idea is to add a new variable into the ships.tbl where we could (optional) put a flyby and engine sound.
$Name: X wing
