Yes. But back to the point, I think there is an extremely good chance that
mus_src (even by setting the width-argument to 5 (default value is 10
which is also faster than SRC_SINC_FASTEST)) will sound better than whats
being produced by a linear resampler, and might be exactly be what the
person asking the question is looking for.
