I made this patch (attached) that does it either the long way (for current 
releases of GridFlow) or the short way (with a feature I re-added to 
GridFlow today).

The trick is to open the file, skip the first 22 bytes, and then read the 
next 4 bytes as a 32-bit number with the most important byte first 
(«big-endian»).

However, because the command for reversing the order of the bytes was 
missing, I had to make my own converter by taking 4 separate bytes...

Anyway. Now you have something that works, and it's easy to add to your 
patches. It does basically the same thing that [soundfiler] does, but 
without reading the actual sound.

You need to install GridFlow from http://gridflow.ca/
