My understanding is that you don't need to do this - if they're
individually encoded with the same encoder, at the same quality, they
should use the same codebooks.  You could then just strip the headers,
and have your program use the headers to init the decoder before
playing back each headerless sample.  IANAVD, so I can't say whether
this method would be more or less efficient than seeking to selected
offsets in one big file.
