I wasn't aware that WAVEFORMATEXTENSIBLE covered file sizes - the spec
seems to be mostly about "higher resolution" sample formats. what did i
miss?

more portable solutions, i think, include using w64 format or even CAF,
which are both defined with (unsigned) 64 bit file size limits.

I'm a little surprised sox doesn't do that by default.I wasn't aware that WAVEFORMATEXTENSIBLE covered file size=
