@ -318,7 +318,7 @@ It can decimate by a floating point ratio.
It uses Lagrance interpolation, where `num_poly_points` (12 by default) input samples are taken into consideration while calculating one output sample.
It can use an additional FIR filter before applying the Lagrange interpolation. This filter can be activated by:
It can filter the signal with an anti-aliasing FIR filter before applying the Lagrange interpolation. This filter is inactive by default, but can be activated by:
* passing only the `transition_bw`, or both the `transition_bw` and the `window` parameters of the filter,
* using the `--prefilter` switch after `num_poly_points` to switch this filter on with the default parameters.
