This may not match your needs, but may be of general interest.

I saw a recent announcement for a Walkman sized box that plugs into a 
parallel port on one side, and audio input from a mike or amplifier on
the other.  It uses a 16-bit adaptive differential pulse coding method that 
uses about a quarter of the usual space required by PCM coding.  It is
available now, costs about $250, does not take a slot, and complies with 
Microsoft's multimedia extensions to Windows 3.0.  Contact Meridian Data,
(408) 438-3100 and ask about "SoundByte".
