Subject: How to search for ascii char sequence in binary file

So I'm trying to convert e.g. 'RIFF' to e.g. '52494646'.  What's the
best way to do that?  I don't know what the former string will be, be I
know it will be exactly four characters.

I'm searching a binary file for the latter string, but I'm given the
former as the search term.  I'm thinking something like this for the
search:

puts File.read('file.wav').index('52494646')

So... best way to do the conversion, and best way to do the search.
Ideas?

Earle
