IIRC, 'ecasound' has high quality resampler.

http://ccrma.stanford.edu/planetccrma/man/man1/ecasound.1.html :

"
If ecasound was compiled with support for libsamplerate, you can
              use ´resample-hq´ to use the highest quality resampling algo-
              rithm available.
".

Anyway, since output sampling frequency is supposed to be 11025Hz, which is
pretty low, one can't expect high sound quality.
