I think the pitch shift works by either compressing or stretching the
time....
-ei:pitch-shift-%
Pitch shifter. Modifies audio pitch by altering its length.
which i think means that -ei:50, for instance, will make the file play
twice as long while sounding at half pitch and -ei:200 will make
the file play half as long while sounding at twice the pitch.
I did some simple tests on this at home the other night. A pitch shift
of less than 100% is equivalent to time stretching while a pitch shift
of greater than 100% is the same as time compressing.

Only you'd need a file as
input, not a device.
Have you found a way to use ecasound's pitch-shift to stretch a sound at
all? If so, could you post the command line you are using please?
'man ecasound' and 'ecasound --help' didn't mention anything about
time-stretch, only pitch-shift.
Be curious to know.
Best,
D.
