History:

This library is not the highest-quality resampling library
available, nor is it the most flexible, nor is it the
fastest.  But it is pretty good in all of these regards, and
it is quite portable.  The best resampling library I am aware
of is libsamplerate by Erik de Castro Lopo.  It's small, fast,
and very high quality.  However, it uses the GPL for its
license (with commercial options available) and I needed
a more free library.  So I wrote this library, using
the LGPL resample-1.7 library by Julius Smith as a basis.

Resample-1.7 is a fixed-point resampler, and as a result
has only limited precision.  I rewrote it to use single-precision
floating-point arithmetic instead and increased the number
of filter coefficients between time steps significantly.
On modern processors it can resample in real time even
with this extra overhead.

Resample-1.7 was designed to read and write from files, so
I removed all of that code and replaced it with an API that
lets you pass samples in small chunks.  It should be easy
to link to resample-1.7 as a library.
