I had a look at that program. The time streching is done in the time
domain so its only ever going to be any good on certain signals and
over small stretch/pitch factors. The interpolator is also limited
to linear interpolation.
However, I do not think it would be too hard to drop libsndfile into
the SoundStretch code to do the file I/O and you could probably also
replace the existing linear interpolator with Secret Rabbit Code.

That final part I have no answers for (yet).
