This isn't too critical, though, as the string is stopped at the succeeding longname string. This patch fixes such entries by dropping "SB" prefix (it's enough to fit within 32 bytes, so far). Meanwhile, it also changes strcpy() with strlcpy() to make sure that this kind of problem won't happen in future, too.

And it should be 256 * sample rate of AIF1.
