@item filter_size
@item linear_interp
Use linear interpolation if set to 1, default value is 0.
+@item exact_rational
+For swr only, when enabled, try to use exact phase_count based on input and
+output sample rate. However, if it is larger than @code{1 << phase_shift},
+the phase_count will be @code{1 << phase_shift} as fallback. Default is disabled.
+
@item cutoff
Set cutoff frequency (swr: 6dB point; soxr: 0dB point) ratio; must be a float
value between 0 and 1. Default value is 0.97 with swr, and 0.91 with soxr
