[PD] Repairing wav files written by pd 64bit

[thewade]

Someone on linux-audio-user suguested ghex to view the header data.
I only installed hexedit as I have to do a major update to my machine
to get libgnimeprintui22 up to date, and I tried by hand but I gave
up after I had downloaded 40 rpms and there were still more to be
downloaded. Yum aparently cant find all the files it needs.
Anyway I gave up.
