Indeed, some kind of flag will be required.  Perhaps including the
algortihm type such as LS_LINEAR or LS_BANDLIMTED.=20

I have also changed ls_get_resampler to return ls_resample_t:

typedef struct
{
  ls_resampler_init_t init;
  ls_resampler_term_t term;
  ls_resampler_run_t resample;
}
ls_resampler_t;

You need to get a 'void* state' by calling init and then pass
that state on to the resample and term routines.  This is so
the resmapler can save state.  It also means that that you only=20
need to pass 'from_type' and 'to_type' into init and the resmapler
will save the info it needs (such as the resampling factor) between
calles to resample.

cheers,
