[ardour-users] file lengths

This is serious. I was trying to record a long track from DAT source and
ardour hanged when I clicked stop :/ As a result no wav file was created -
1,5 hours of work were lost.

Is it possible to record using raw audio instead of WAV?

RIFF/WAV has an internal length field that holds (2^31) bytes as a maximum

your filesystem can probably get to a 64 bit length. this doesn't solve the
WAV internal length problem.

you can't even get 1 hour from WAV using 32 bit sample format @ 96kHz.
