What advantage is there to keeping a static total recordings count (I
guess you could call it)?  Seems the most sane that each recording
should start at 1 and count up as it already does.  Also, instead of
changing the current numbering system, could using a hash provide you
with the same result you're looking for?  I would think hashing the
first X MB of a recording would suffice to create a unique identifier.
