Almost. There's a single field in the primary header (the first ~50 bytes
or so of the file) for sample rate. However, you also need to fix the
page checksum if you change that (which is not something you want to do
by hand). It'd be pretty easy to write a simple tool to fix this up using
libogg (and maybe libvorbis)
