as already noted, wav can't go this big. the header has a 32 bit value
inside it to indicate the filesize.

if you search the LAU archives you'll find someone else who managed to
do this with another tool, and someone (2 or 3) people came up with
tools/solutions to save the day.

use w64 format, or CAF.
