Big problem there. Valid WAV files cannot be larger than 4 gig. Many
programs won't open a WAV file larger than 2 Gig. 2 Gig is 90 minutes
of stereo float data at 48kHz.

W64 allows files very much larger (2^63 bytes).

Would it help if sndfile-play had a Jack back end?

Seems to work here with small files. Can you be more specific?

Does libaudiofile even support the W64 file format?

Any editor which uses libsndfile should read that file quite happily.
I use Sweep (http://sweep.sf.net) but Audacity should also work.

The main confusion about C++ is that its practitioners think
it is simultaneously a  high and low level language when in
reality it is good at neither.
