If you compile
ecasound with SRC support the shift is limited to 12x in either
direction.
That was true for SRC up to and including 0.0.15. For version 0.1.0
released a couple of days ago, that has changed to +/- 256.
Also, be aware that this is not a pitch shift effect, because the
durartion is not constant. The effect is more accurately described
as a vari-speed effect.
But, as Steve pointed out to me on #lad last week(?)
you can
do multiple iterations to get greater shifts/stretches. Using SRC the
resulting sound is somehow smoother sounding than with the internal
ecasound version.
If the internal ecasound on is linear or polynomial interpolation,
then that would make a lot of sense.
