thanks, josh.  i had come across that quite some time ago (a fairly
memorable logo :^) ), but had since lost track of it.

browsing the api, it performs the following conversions on float sample
data, with conversion ratio represented by a double:

enum
      {
          SRC_SINC_BEST_QUALITY       = 0,
          SRC_SINC_MEDIUM_QUALITY     = 1,
          SRC_SINC_FASTEST            = 2,
          SRC_ZERO_ORDER_HOLD         = 3,
          SRC_LINEAR                  = 4
      } ;

where "SINC" is the "Julius O. Smith" method
( http://www-ccrma.stanford.edu/~jos/resample/ ).

it's designed to process data in streams..  so, this library would
probably work well for the 'standard' scaling methods.  and it's GPL.
