There is nothing in Unix/Linux which prevents the playback of a file
while it is being recorded. File locks in Linux are purely advisory; it
is up to the applications whether they choose to respect them.

The only challenge is whether the header has been written correctly, and
you should be able to do without that in a pinch. What happens if you
copy the half-written file to a computer with speakers and try to play
it through the speakers?
