Examples¶

See the Farrow arbitrary resampler example.

Constructors¶

FarrowResampler(streaming: bool = False)

Creates a new Farrow arbitrary resampler.

Special methods¶

__call__(x: NDArray, rate: float) → NDArray

Resamples the input signal \(x[n]\) by the given arbitrary rate \(r\).

Methods¶

reset(state: ArrayLike | None = None)

Streaming-mode only: Resets the filter state and fractional sample index.

Properties¶

property taps : NDArray

The Farrow filter taps.

property order : int

The order of the filter.

property streaming : bool

Indicates whether the filter is in streaming mode.
