Try: sox $FILE -n stats 2>&1 | awk '/^Length / {print $2}'

That will decode the entire file and run it through the
sox "stats" effect.

I just tried it on a 28MB FLAC file (3:49.80s) truncated to 5MB

	dd if=$ORIG of=truncated.flac bs=5M count=1

And was able to reproduce soxi showing the the length as
3:49.80 but "sox .. -n stats" showed only 44.304s
