Filter related query

Hello all,

In the GNU code, mmse fir interpolator filter code is used. In case we
detect less number of samples between two frames than expected sample
rate,
we do interpolation.

In case we detect more number of samples between two frames than
expected
sample rate, we need to do decimation. Can we use the same filer for
decimation purpose with modification or any other filters available in
the
GNU list?

Regards
