Err, actually, up to 2^32+7 bytes is ok for WAV [0]. More than
that and you have an invalid file. Many programs will produce
an invalid WAF file if you ask them :-).

[0] A WAV file consists or four bytes 'RIFF' followed by an uint32_t
    with the length of the file following the length field. Biggest
    number in a uint32_t is 0xffffffff so the file can be that big
    plus 8 bytes for 'RIFF' and the length.
