Pure user software doesn't have to. But system tools have.

For the others it's not visible. If you have full memory protection (paged) then even the address is wrong (may map anywhere in your process). And there are eventual pointers in the message itself.

I don't use WAV because i don't want to waste disk space. Btw AIFF is more suited for the Amiga (no little endian to convert).

Anyway you can't do that for video.
