62 However, if you feel there is too much (or not enough) lowpass
63 filtering, you may need to try different values of the lowpass cutoff
64 and passband width (--resample, --lowpass and --lowpass-width options).
133 --lowpass Frequency(kHz), lowpass filter cutoff above freq.
135 --lowpass-width
136 Frequency(kHz), lowpass window width.

525 Enables a lowpass filter of the specified frequency when encoding the source.
