Others have told you what you need to do to get this working. I just
wanted to chime in to say that ecasound will use libsamplerate quite
well if you get things configured correctly. But, ecasound also has
builtin routines to do most of what libsamplerate does. It's just that
libsamplerate does those things with much greater quality. So, you can
still do pitch shifting with the -ei effect and resample with the
resample input object type without libsamplerate. If I understand
correctly once you have libsamplerate working with ecasound you have to
specifically ask for high quality resampling for input objects, but -ei
uses libsamplerate by default.
